It is so refreshing to hear such an intelligent doctor with a sense of humor. All of Dr. Mason’s lectures are very informative and I look forward to listening to him.
Dr. Mason is spot on! Carnivore here. I'm extremely white and all my life have been highly sensitive to Sun exposure! Usually resulting in burns! Not so long ago, most of my company went for a outdoor all day long work. Under the Summer Sun. I was the ONLY one not using Sunscreen, of any sort. Being a office/desk guy I gambled that. Side by side with some colleagues who indeed spend most of their days outside. Lo & behold I DID NOT get any Sun burn. And most surprising on the next day(s) I had a hint of tan!!! 🙂 I'm 55 and I was mesmerized by the experience! Cheers
Unfortunately this was just an 'off the cuff' talk so there is no 'full talk'. I was considering doing a presentation on vitamin D, however I changed my mind to do a deep dive on cholesterol and heart disease instead. The conference programme indicated I was going to do something on vitamin D however, so Rod Tayler asked me to give a short impromtu talk on vitamin D.
@@drpaulmasonMD Hi Paul, firstly you're amazing, I'm kind of addicted to macadamia nut butter, generally otherwise a carnivore diet - but I top up my fat with macadamia nut butter as it's divine and it helped get me off all high-carb and sugar sources!! I thought it was the perfect nut - high in sat/monounsat fats, v. low pufa, low in phytic acid, allergies uncommon... BUT - could the phytosterols contained be a hidden problem? I have at least 100g a day... but concerned about the possible phytosterols which you have also mentioned before are undesirable. Would truly appreciate your thoughts... might I be setting myself up for future cardiovascular complications by my innocent (so I thought) macadamia nut consumption :D
@@MrSidReal I think the research is divided and conflicted on that issue. a lot. 100g is probably a lot from my personal experiences with the nuts themselves. when consuming nuts, I think it is wise to ponder how difficult it is to open them. and. thus. how many could you actually eat (vs a bag of shelled .. or a crushed product in a jar). nature put them in a hard tough shell for a multitude of reasons. if you are seeking benefit .. I would stick to whole foods ... such as Nuts: macadamia nuts, hazelnuts Seeds: watermelon seeds Fruits: pineapples, oranges, berries, bananas, apples, apricots Vegetables: artichokes, sweet potatoes, celery, cauliflower Legumes: mung beans. Oils: olive oil, argan oil. and be thankful that the mac-butter has let you transition to a better state of being. keep going.
I can vouche dor this. After a few months on a hypercarnivore diet, my skin was extremely resilient and resistant to the sun and I held most of my tan through the winter months.
I'm pretty sure this is due to a reduction in excess PUFA intake, specifically Linoleic Acid. Over time avoiding seed oils and other foods high in Linoleic acid, I've noted I am sunburn resistant. I just spent 8 hours in the sun without prior exposure this year. While I did burn slightly, it was very minor, did not hurt at all, then fully healed in a few days. I've also noted an end to chronic pain, arthritis, asthma, reduced allergy severity, and improved cognition and mental health. I'm mostly animal based, but probably moderate carb at this point after 5 years of avoiding Linoleic Acid. I'm not 100% sure the primary cause was the linoleic acid, but am fairly confident. I'm of course open to other ideas and potential causes though, if given convincing and robust data.
I agree. I went Ketovore and now I can go unprotected into the summer sun and not get burned. Quite amazing. It is truly correct. I don't eat anything but pure meat, fat and organs and I now do not fear the sun at all. I just get tanned and it feels good. For 25 years I would have been burned. It's definitely correct that Ketovore gives you sun tolerance.
Let's not ever forget, Dr Keyes 'seven countries' study was created as such, because the other 14 countries that he ALSO had data for, didn't support the hypothesis he was presenting. So he just ignored them.
Dr. Eric Westman, founder of the Keto Clinic at Duke University, said that in his many years of medical practice he never prescribed vitamin D supplements to any of his patients. He said that as his patients lost body fat with his prescribed, very meat heavy keto diet, their vitamin D levels always improved significantly.
Amazing, what a brilliant discovery; it's almost like vitamin D is stored in the fat precisely because it's so important. Man, what a moron that guy must be. When the vitamin D reserves run out, many of those people are going to experience serious adverse consequences.
@@DP-yu4rr You missed the point. It's not about Keto. It's about losing body fat by any means. A published study titled "Vitamin D Deficiency: Consequence or Cause of Obesity?" says "weight loss is currently the only actually proven treatment that leads to improvement in a number of disorders, including Vitamin D deficiency."
Man this doc just continues to blow my mind. Now I’ve got to completely rethink my love of the sun. He goes into this deeper on his podcast with Dr. Chaffee plus a whole bunch of other gems. I highly recommend it!
The worst things to ever happen in OZ were Slip Slop Slap and Don't eat red meat and saturated fat. Since going Ketovore I am so much more sun tolerant and don't burn. I have never used sun screen.
I'm not sure what Mason's overall point is here thought. I think he's saying getting vitamin D via the sun is good. But it won't work if you're obese. Is that the main point YourLifeRedifined?
Outstanding! This makes so much sense. I've had a question about the importance of VitD because I live in a northern country (Scotland) where it is often not sunny (even in summer) and between October & April it is impossible to get VitD from the sun. My ancestors were not renowned for running around naked (except perhaps in battle) because it is either too cold or the midges would make your life hell! Not to mention the matter of modesty... Rickets is a relatively modern affliction on the Scots (think Victorian slums up until they started to get knocked down after WWII) so how were we getting our VitD for the past 2000-8000 years if it can't have been from the sun? Eating animal fats makes complete sense, of course, but maybe we just didn't need it because we were metabolically healthy in the past (we certainly aren't now!) & were not subject to lots of sun exposure. Anecdotally, I also lived in New Zealand in childhood & suffered terrible sunburn at times & continued to do so throughout adulthood in Scotland & working in the tropics or holidaying in southern Europe. I grew up with a 'perfect' plant-based diet until my early 40s (& have health problems to show for it). I went mostly plant-free about 5 years ago & my ability to cope with sun exposure has never been so good. I do burn but nowhere near as badly as I used to.
I went Keto 2 years ago and then Ketovore 1 year ago and my sun tolerance (and not getting burned) went up. I actually crave sunshine and feel great. I used to avoid the summer sun and now I love it. My experience is simply that you don't get burned even when in hot midday summer sun. I was quite amazed. I am zero carb and consume no seed oils, sugars, carbs nor processed foods - Only meat and fat (nose to tail).
Ketovore is such a funny word, since it implies "eating ketones" even if it means halfway between a pure animal-based die and an unrestricted ketogenic diet.
Tim Spector of the ZOE program, in his Twins study, found there is no one perfect diet. Diff. diets affect diff. people differently. The key is to find what works for YOU!@@Matto_Harvo
There are some awesome doctors, scientists, and journos in the low carb sphere. Mason is among the top, as well as Bikman. They're brilliant people with the knowledge to save millions, the desire to spread that knowledge to anyone who seeks it, and the gift of being able to communicate that knowledge in an approachable manner.
Carnivore for 5 months prior to a San Diego summer. Surf, swim, run regularly in the sun. One day, got caught up at the beach for 2 + hours (unplanned) no sun screen, zero sun burn at all.
It's an interesting topic. Where do animals get their vit D from? And fish, for that matter, does UVB penetrate water? Why were almost all covid patients vit D deprived? Why were people of color over-represented in the hospital intakes? Doesn't the sun also produce nitric oxide for us? How much do we really know of the processes going on when we're out in the sun?
one of our sources of supplemental vitamin d3 was (not sure these days) from sheep's wool. So animals can make d3 from hair/fur, skin or if carnivores, from food. Fish get vitamin d from plankton who get their vitamin d from the sun and are very very good at the process of making this vitamin.
Concerning patients with low vit D. He talks exactly about that. People with large BMI were also at considerably higher risk. Since vit D is fat soluble one can argue that the same intake of vitamin D manifests itself in lower blood values in people with large BMI. And large BMI correlates with poor metabolic health.
You are absolutely correct that we can synthesise nitric oxide from the sun which has significant health benefits - this however is produced by UV-A rather than UV-B which stimulates vitamin D production -- all covered in this video - ua-cam.com/video/Kvh4D_osFXs/v-deo.html
@@FedorBP But this is also an association only. The real question is whether it s the obesity which lowers vit D in the blood stream, or rather the same condition which has caused obesity is also what is causing vit D deficiency. I would bet the later (dietary sugar and subsequent high insulin being the most suspicious)...
I don't get sunburned anymore, 18 months keto, heading towards carnivore. I do limit my sun but even if I overdo it, I still just redden and then that tans. Interesting talk, thank you!
Brilliant as always. I spent 6 weeks on the sun in northern hemisphere and got back with highest vitamin D levels ever in my life and a significantly reduced cholesterol levels. So yes, it makes sense.
I believe in Vitamin D but I do not have access to sunlight and most people don't. I work 12+ hours a day - not by choice - and I live far north. Supplementation is fine for me right now thank you very much.
Have you watched the video? He clearly states that getting the vit.D one needs is much less related to sunlight exposure than people give it credit for. It helps, but it's not ultimately needed. If your diet is right, you won't be needing that much sun... or supplementation.
This is my experience. I used to fear getting burned and now I go in the hot midday Qld summer sun and simply go brown with no burning. Ketovore makes you sun tolerant.
@@DaKeezl I quit all oils plant oils, including Avo, Olive & Coconut. Dr Mason has a talk on how plant oils are slightly different to animal oils, search "Differences between phytosterols with different structures in regulating cholesterol synthesis, transport and metabolism in Caco-2 cells"
Very interesting. So you don’t need sunlight to maintain healthy vitamin D levels. What about the other benefits of sunlight, for example, increasing serotonin, treating some skin conditions, and generating nitrous oxide. Are these still valid, or do we need to also rethink them?
There is no doubt there are other benefits of sunlight exposure, mainly relating to nitric oxide. I discuss that in this older lecture - ua-cam.com/video/Kvh4D_osFXs/v-deo.html. (also circadian entrainment is also hugely beneficial).
Good question, to me the vitamin D from supplements to treat Covid initially seem positive, but subsequent looks were not so positive. What seem to be the positive affect was the exposure to sunlight, and the things you talked about, including melatonin at the myocardial level. However, the larger point of this presentation to me is the idea of supplements. On the one hand, unhealthy people take supplements to be healthy and the research on that does not bear out supplements work. The question is do metabolically healthy people need to be taking supplements and I think Dr. Paul is saying vitamin D may not be needed for people with healthy diets and lifestyles.
I would add that whilst it might not be necessary to get your Vitamin D from the sun. The Sun also provides other important benefits such as circadian rhythm regulation, sleep, increases in nitric oxide. improvements in mental health and the list goes on.
Dr. Mason doesn't negate that, he actually has talked about the subject many times, mentioning all these points in fact. Sunlight is great for us in many ways, really. Case here is that he just doesn't overstate the role of sunlight in getting the actual vitamin D we need like many people do.
I am a redhead/fair skinned, this feature evolved in humans living in the high latitudes in europe where extra absorption of of sunlight was an evolutionary advantage (Via D maybe only one of many advantages). Too much sunlight for redheads is bad, as I live in Sydney and spent my childhood outdoors, I have had many skin cancers burnt off/cut out over the years. My siblings with blond hair and darker skin eating the same diet (included margarine) do not suffer from skin cancers. The benefits/risks of sun exposure are complex and even with the risk of more skin cancers I still get 10/15 minutes of sunlight in the middle of the day when I can.
I saw a video just two days ago talking about the bullet holes in planes were misinterpreted by engineers due to 'survivorship bias'. I got that one correct...
It could be like vitamin C. Very tiny amounts go a long way in a healthy carnivore human. A human that doesn't consume mineral-sucking phytates, for example.
Interesting presentation. No mention however that the majority of people are Vit D deficient when tested, so this potentially implies two things. One that people do not get the full body exposure to sunlight that they used to, and second, that diet alone is not delivering the goods. P.S. Begs the question: are the defined levels for Vit D deficiency actually correct?
Interesting proposition. Counter-point: sunlight is a requirement of a heathy lifestyle Sunlight and UV provides more to the skin and body than just vitamin d synthesis
Agreed. While bodies shield us from the more harmful spectrum of radiation but rely on the near infrared rays for circadian rhythm, switching back and forth from the pineal producing melatonin at night to the mitochondria producing it during the day. Sunlight is more natural to the eyes while unnatural LEDs and flourescents are harming our health. Sun bathing used to be considered healthy before so called experts started fear mongering about cancer. What could be more natural than sunshine?
All I know is before I supplimented with vitamin d i would get 2 or 3 bad colds a year but since taking 20000 iu a day I have not been sick In 5 years nothing else has changed including my weight.
This sounds amazing to me... I get sick almost weekly for the past 4 months and it's really making me go insane.... Meanwhile everyone else is fine ... I just order 50k IU to take weekly so I'm gonna see if that helps... I have a new born so I'm sure he is sucking the vitamin d stored out of me and plus we r indoors a lot
This sounds very eye opening and does make sense but also raises one question for me: If not for low levels of vit D, why are people more susceptible for sickness at the end of winter? Or is it only the part of population that eats (mostly) vegetable oil based diet that get more susceptible?
Studies have shown Vit D is important in immune function, and on a cellular level. Vit D produced within the cell is likely superior. In a similar manner, melatonin is produced in the mitochondria when exposed to near infrared light. Being an antioxidant, this can help combat reactive oxygen species. This is in much larger quantities and more effective than the melatonin produced by your pineal gland.
Given how low risk even milligrams of daily vitamin D3 seem to be, and of the potential benefits, I'm not going to stop microgram level supplementation anytime soon. The discussion around it is interesting though, and likely the purpose of the talk/video, rather than convincing people to stop supplementing.
Don't forget one thing: the Inuit diet is fructose-free. Inuits don't have to fight with excessive fructose intake. (btw their blood sugar levels are perfectly fine)
I can't stop laughing. Do you seriously believe your own bullshit? Inuit blood sugar levels are perfectly fine? Inuits have historically been the shortest-living and most disease-ridden populations on the entire planet by a wide margin. And no, it's not because of "Western diet", it's their traditional diet which has historically led to those abysmal outcomes. In fact, the opposite is true: more access to "Western" foods has drastically served to improve their health. Get a grip. *_«These data show high CHD and stroke prevalence in Alaska Eskimos, despite low average LDL-C and high HDL-C. Hypertension and high LDL-C were independent correlates; identifying these risk factors early and treating to target is recommended.»_* *_«The current belief that the Inuit are protected from CVD is seriously questioned by the results of the present study. Considering the extremely high prevalence of CVD risk factors, a population-based intervention reinforced for women is urgently needed to reduce their risk.»_* *_«The data collected through this new investigation shows that Eskimos do have a similar prevalence of CAD to non-Eskimo populations, and in fact, they have very high rates of mortality due to cerebrovascular events (strokes). Overall, their life expectancy is approximately 10 years less than the typical Danish population and their overall mortality is twice as high as that of non-Eskimo populations.»_* *_«“Considering the dismal health status of Eskimos, it is remarkable that instead of labeling their diet as dangerous to health, a hypothesis has been construed that dietary intake of marine fats prevents CAD and reduces atherosclerotic burden,” remarks Dr. Fodor.»_* *_«The mortality from all cardiovascular diseases combined is not lower among the Inuit than in white comparison populations. If the mortality from IHD is low, it seems not to be associated with a low prevalence of general atherosclerosis. A decreasing trend in mortality from IHD in Inuit populations undergoing rapid westernization supports the need for a critical rethinking of cardiovascular epidemiology among the Inuit and the role of a marine diet in this population.»_*
at 2:47, dr mason seems to imply that the synthesis of vit d uses up and reduces the level of cholesterol. considering that vit d is measured in micro-grams, this doesn't make sense. removing micro grams of cholesterol should not make much difference to the amount of cholesterol in total.
i love thinking differently. I also love thinking quantitatively. The argument that people in sunny areas have lower cholesterol because of synthesis of Vit D is most likely garbage. GFirst, between 5..7g of chol are turned over by the body without external supply of it, that is, the body maintains that throughput, and makes 1g to replace the loss. Vit D is FAR LESS by weight. Conclusion. hose people have a completely different set point for chol, not the direct causality sun -> vit D, but because lide in these sunny areas is very different. Those other differences are the important ones: more antioxidants, more movement, less cellular damage, hence less need for the bodies garbage collecting system (==cholesterol)
I do feel he’s undershot the truth about sun’s primary hypothesis position as a highly necessary and beneficial aspect of metabolic and hormonal health. Other talks list more cellular effect pathways of vitamin D. While the amount of D in foods does seem to be up to larger debate than I’d seen, I still don’t buy that little sun and just the right foods is the ideal solution, at all. Evolutionary framework has to undergird. He mentioned plankton using vitamin D as sunscreen, but still adopts the “the sun is damaging” motif. Seems like a thin motif to me.
Not all sun is damaging. UV-A which stimulates the production of nitric oxide is quite beneficial. Unfortunately I was just asked to speak for 5 minutues, and I was getting the 'your time is up' signal from the back as I was about to discuss nitric oxide.
@@drpaulmasonMD: So you decided, "hmm, how can I cram as much as possible of the diametric opposite of the truth into this 5-minute presentation?"; nice going, well done; you certainly achieved your objective.
I would disagree with the statement that Vit D is a "sunscreen". I believe it is melanin ( derived from an amino acid, not a fat) that is the sunscreen. I am very happy to hear a counter argument.
All this is great. But what should we do with dr John Campbell and his reviewing of vitd sypplementation studies and the huge health benefits?? Especially in dementia and Alzheimer's
Completely ignores all the other reasons why we need direct sunlight exposure. Regulating biorhythms, positive effects on mental health, etc. Also, humans lived outside for most of our history, so why didn’t our species die of skin cancer if sunlight were so bad for us?
His theory is a huge stretch. Seems like he confused vitamin D with melanin. As vitamin D synthesis drops after melanin production kicks in. So if you are tanned you produce less vitamin D.
Paul’s talk was targeted to D3 specifically - not total sunlight exposure benefits. His lengthier videos contain much more data. Sunlight has many benefits for optimal human functioning… getting a sunburn is detrimental to humans health.
Im a carnivore a year, keto 8 yrs, NO seed oils but I havent seen the sun in 10 yrs. I wonder alot about this Vitamin D. I take 5000 IU a day but often wonder if its enough. Thank you for your video.
Supplemental dose of vitamin D3 is 600-800 IU /day (NIH,America). Maximum tolerable dose is 4000 IU/day.Check your Vitamin D level in blood which should be 50-125 nmol/L . Blessed be.
I also take 5000 IU a day Got my blood tested and the results were: 170 nmol/L It’s Above the ”optimum levels” but it’s still in the range which you can aquire naturally by the sun. Toxic levels are 375 btw. So I will continue taking 5000 IU and cut down a bit when I’m out in the sun.
An actual carnivore doctor who brings us real, useful information based on his intelligent thinking. The majority in this community just give you a sales pitch, copying what someone else said, or basing their talking points on a flimsy study or two. I have turned away fromthe carni community lately because of the hucksters, but Mason and a few others bring me back.
Dr. Michael Hunter in the TV series about how famous people died (Autopsy: The Last Hours of) keeps being negative about meat based diet. Dr. Mason should have a talk with him.
@@byoken yes. It is a weird phenomena. Every year (not as a child late 60's or early 70's) I would get burned quite easily that first couple/few times out. You do not realize but when you get home it comes on.... peeling every year. Been 100% carnivore for 2 summers now and both times no sunburn WSE. Not to mention the shopping list of illnesses I cured doing it...metabolic (severe), liver, prediabetes, chronic hay fever, polymyalgia rhuematica, chronic fatigue.
I'm Carnivore 8 months, but i do take vitamin d supplements because here in the uk, the sun is a rare thing to be seen, the cloud's are most common sight.
I've been listening to LCDU and Dr. Mason for some time. Great information. I am wondering if there are any studies on Cholesterol levels and low Vitamin D. From what I understand, our body will make the level of Cholesterol it thinks it needs. Vitamin D is extremely important for overall health and sun exposure to the cholesterol in our cells produce Vit. D. Most of us are Vit. D deficient. Is it possible that the high cholesterol in many people is the attempt of the body to generate more Vit. D?
I used to get bad, really bad sunburns from as little as 30 minutes in the sun. When fasting or on a carnivore diet my resistance goes up to two, even three hours in the sun without a burn.
I am in my early 60s, and in addition to eating a keto/carnivore diet for several years, I have also supplemented with 8,000 IU of vit D3 daily for about 2 years, yet when I recently got blood tests that included vitamin D, 25-Hydroxy, my level was 42.9 ng/mL on a scale of 30.0 - 100.0 so not even in the upper half of the normal range. Also, I work outdoors in the subtropical state of Florida in the US, though I do cover up and wear sunscreen to avoid skin aging and skin cancer.
Supplemental dose of vitamin D3 is 600 IU/day(NIH,America).In spite of higher dose your D3 level is within normal range.Some factors must be playing.What other medicines are you taking?
The sunscreen/cover prevents your body from producing vit D. It does seem common for very low levels of vitD in populations of sunny places where sun exposure is avoided, or screened, with low animal fat diets providing hardly any either.
I always sufferd with winter depressions, tought it run in the family until i learned that i had Lipedema and a study been done that showed that the patients in the study had low vitamin D. I love the din and eat vitamin d but still get realy low in winter time.
Im always curious how ancient peasants in Europe fared without any sunscreen yet prominent exposure to UV rays, let alone those exported to colonial areas to work the fields there for example the Portuguese used their jewish population on their colonial islands. Would the skins melatonin after prolonged exposure be good enough? Does sun burn help the skin to more rapidly protect itself? Did they use mud or other forms of protection?
I took a vitamin D supplement for a few months this winter, because my levels were a bit low, I wasn't getting much sunlight, and I thought it couldn't hurt. I ended up with a low platelet count. Apparently vitamin D supplements lower platelet count, but my doctor didn't tell me this when she recommended a vitamin D supplement while my platelet count was near the bottom of the reference range.
" According to the results of this study, lower vitamin D levels will cause higher platelet counts in people with normal calcium and magnesium levels. " As per - cms.galenos.com.tr/Uploads/Article_40039/GMJ-62-174-En.pdf
A high vitamin D level is an indicator of good metabolic health. We can get enough from animal foods. You don’t need to rely on the sun to get your vitamin D. Don’t get your vitamin D from a bottle. Also, don’t be fat.
Just because vitamin D may also be a good sunscreen doesn't mean that getting it by all 3 ways (diet, sunshine, and supplements) isn't beneficial for other reasons.
So other than as a sunscreen and doing something to make healthy bones, does vitamin D have any other functions? And why those two very different functions (sunscreen and bone health)?
I am confused now. Other keto doctors like dr. Berg, dr. Berry say that supplementation of vitamin D3 is essential for good health because this vitamin take part in multiple reactions in the body (not only for sunscreen or rickets). Now dr. Mason says that supplementation is not necessary. Hmmmm.
If you just eat human food (Ketovore) you don't need supplements. Paleo man didn't have D3+K2 pills.... We have the same genetics as we did 2 million years ago. Don't think so hard.
Eric Berg is a chiropractor and a Scientologist who just repeats things from others and sells questionable, ineffective supplements. Unsubscribe from him.
Interesting conjecture. I'm not going to hold my breath waiting for research into it though, probably won't happen in my lifetime. On the sun-burn side, I had never thought about it until now. After 6 years low-carb then keto, I can't recall a single incident of sun-burn. But shortly before starting, I watched a tri-athlon in Provence in the month of May, I think. I had forgotten to bring a cap and got well sun-burned. It was quite embarrassing because I had to renew my passport and the photo was taken with my sun-burn... A couple of weeks ago I had a one day stopover in Abu Dhabi and spent the time walking around between the city centre and the beaches. It was 39°C and I was just stupidly wearing a T shirt. Back home I realised I didn't get sun-burned, which vaguely surprised me, but hadn't thought about it until viewing this video. Maybe there's something in his conjecture - at least for sun-burn.
I have vitiligo, very patchy all over, European ancestry. I am on basically high protein, healthy fats, few vegetables and nuts, 13 hr intermittent fasting. Vitamin levels 70+. Can I do sun?
Dr. Mason just did a slam dunk on the normie view of vit D and I’m all for it. Next up: we need your take on vit A and copper toxicity from excessive organ meat consumption 😅
Hmm.. I think it's scary how people can change their beliefs after a 5 minute talk of one person expressing his thoughts without showing any bit of evidence. It's a research and discussion subject at best, I don't see the slam dunk.
Help me understand, Inuit eat fish which is high in vitamin D, if you don't eat fish, then all I am left with is eggs and not much else, meat, poultry and cheese are very low in vitamin D.
A very important point to consider is that our nutritional databases are possibly significantly underestimating the amount of vitamin D in terrestrial animal source foods. Due to not accounting for the Calcifediol content in said sources. the form which our body turn vitamin d3, d2 and alike into in order for it to use it. And it is known that Calcifediol has a much greater affect on blood vitamin d levels tham d3. There is actually some data on the content of Calcifediol in terrestrial animal source foods. And there is a paper which attempts to calculate the vitamin d content of such foods, adjusting for the Calcifediol content and it’s average affect on blood levels of vitamin d. it estimated that the actual vitamin d content was much higher than the current databases report. offering a potential explanation for how people going on low carb or even carnivore diets aren’t lacking in vitamin d. As well as explaining the discrepancy between apparent vitamin d consumption and lack of deficiency in the general population. Which was the main focus of the paper. academic.oup.com/jn/article/144/5/654/4578279
I can listen to Dr. Paul Masson speak for hours.
the same! :)
Yes, he does a good job of making things understandable...
He's a rock star!!!
Brilliant listenable young man!
Same here! Brilliant human being
It is so refreshing to hear such an intelligent doctor with a sense of humor. All of Dr. Mason’s lectures are very informative and I look forward to listening to him.
Yes he cured me from veganism, eating fibre, and many other things. Now I don't take any drugs, lost weight naturally and feel great thanks to him.
He's a pleasure to listen to. You can tell he's a really kind man as well. 💗
Dr. Mason is spot on!
Carnivore here. I'm extremely white and all my life have been highly sensitive to Sun exposure! Usually resulting in burns!
Not so long ago, most of my company went for a outdoor all day long work. Under the Summer Sun. I was the ONLY one not using Sunscreen, of any sort. Being a office/desk guy I gambled that. Side by side with some colleagues who indeed spend most of their days outside. Lo & behold I DID NOT get any Sun burn. And most surprising on the next day(s) I had a hint of tan!!! 🙂
I'm 55 and I was mesmerized by the experience! Cheers
OMG How can one person share so much useful knowledge in just 5 minutes !!!
Now we need to see the full talk please.
Unfortunately this was just an 'off the cuff' talk so there is no 'full talk'. I was considering doing a presentation on vitamin D, however I changed my mind to do a deep dive on cholesterol and heart disease instead. The conference programme indicated I was going to do something on vitamin D however, so Rod Tayler asked me to give a short impromtu talk on vitamin D.
@@drpaulmasonMD Hi Paul, firstly you're amazing, I'm kind of addicted to macadamia nut butter, generally otherwise a carnivore diet - but I top up my fat with macadamia nut butter as it's divine and it helped get me off all high-carb and sugar sources!! I thought it was the perfect nut - high in sat/monounsat fats, v. low pufa, low in phytic acid, allergies uncommon... BUT - could the phytosterols contained be a hidden problem? I have at least 100g a day... but concerned about the possible phytosterols which you have also mentioned before are undesirable. Would truly appreciate your thoughts... might I be setting myself up for future cardiovascular complications by my innocent (so I thought) macadamia nut consumption :D
@@MrSidReal I think the research is divided and conflicted on that issue. a lot.
100g is probably a lot from my personal experiences with the nuts themselves.
when consuming nuts, I think it is wise to ponder how difficult it is to open them. and. thus. how many could you actually eat (vs a bag of shelled .. or a crushed product in a jar). nature put them in a hard tough shell for a multitude of reasons.
if you are seeking benefit .. I would stick to whole foods ... such as
Nuts: macadamia nuts, hazelnuts
Seeds: watermelon seeds
Fruits: pineapples, oranges, berries, bananas, apples, apricots
Vegetables: artichokes, sweet potatoes, celery, cauliflower
Legumes: mung beans.
Oils: olive oil, argan oil.
and be thankful that the mac-butter has let you transition to a better state of being. keep going.
I can vouche dor this. After a few months on a hypercarnivore diet, my skin was extremely resilient and resistant to the sun and I held most of my tan through the winter months.
I'm pretty sure this is due to a reduction in excess PUFA intake, specifically Linoleic Acid.
Over time avoiding seed oils and other foods high in Linoleic acid, I've noted I am sunburn resistant.
I just spent 8 hours in the sun without prior exposure this year. While I did burn slightly, it was very minor, did not hurt at all, then fully healed in a few days.
I've also noted an end to chronic pain, arthritis, asthma, reduced allergy severity, and improved cognition and mental health.
I'm mostly animal based, but probably moderate carb at this point after 5 years of avoiding Linoleic Acid.
I'm not 100% sure the primary cause was the linoleic acid, but am fairly confident.
I'm of course open to other ideas and potential causes though, if given convincing and robust data.
What's hypercarnivore?
I, unfortunately, can't. Got burned just the same this spring as the last.
@@AnnabellaRedwood good question, maybe just eating raw meat and nothing else?
I agree. I went Ketovore and now I can go unprotected into the summer sun and not get burned. Quite amazing. It is truly correct.
I don't eat anything but pure meat, fat and organs and I now do not fear the sun at all. I just get tanned and it feels good. For 25 years I would have been burned.
It's definitely correct that Ketovore gives you sun tolerance.
I'm a simple girl... I see Dr Mason and I click play.

Circular profits of the Medical -Pharmaceutical-Agricultural Complex #MPAChealth
Dr. Eric Westman, founder of the Keto Clinic at Duke University, said that in his many years of medical practice he never prescribed vitamin D supplements to any of his patients. He said that as his patients lost body fat with his prescribed, very meat heavy keto diet, their vitamin D levels always improved significantly.
Interesting.
Amazing, what a brilliant discovery; it's almost like vitamin D is stored in the fat precisely because it's so important. Man, what a moron that guy must be. When the vitamin D reserves run out, many of those people are going to experience serious adverse consequences.
BUT NOT EVERYBODY WANT TO DO KETO°
@@DP-yu4rr You missed the point. It's not about Keto. It's about losing body fat by any means. A published study titled "Vitamin D Deficiency: Consequence or Cause of Obesity?" says "weight loss is currently the only actually proven treatment that leads to improvement in a number of disorders, including Vitamin D deficiency."
@@Slopo777 interesting
Every physician on the face of the earth should be strongly encouraged to take in this information. Sadly, I don’t see it ever happening. Thanks Doc!
Man this doc just continues to blow my mind. Now I’ve got to completely rethink my love of the sun. He goes into this deeper on his podcast with Dr. Chaffee plus a whole bunch of other gems. I highly recommend it!
he also gave a presentation on benefits of UVA vs UVB. worth a watch!
The worst things to ever happen in OZ were Slip Slop Slap and Don't eat red meat and saturated fat. Since going Ketovore I am so much more sun tolerant and don't burn. I have never used sun screen.
Sun bathing your eyes, not directly to the retina, is really good for your brain chemistry. Check out doc Huberman.
I'm not sure what Mason's overall point is here thought. I think he's saying getting vitamin D via the sun is good. But it won't work if you're obese. Is that the main point YourLifeRedifined?
One of the best sources of health and nutrition information I have found.
Mason is a wealth of knowledge and I am thankful he shares it with us.
Outstanding! This makes so much sense. I've had a question about the importance of VitD because I live in a northern country (Scotland) where it is often not sunny (even in summer) and between October & April it is impossible to get VitD from the sun. My ancestors were not renowned for running around naked (except perhaps in battle) because it is either too cold or the midges would make your life hell! Not to mention the matter of modesty... Rickets is a relatively modern affliction on the Scots (think Victorian slums up until they started to get knocked down after WWII) so how were we getting our VitD for the past 2000-8000 years if it can't have been from the sun? Eating animal fats makes complete sense, of course, but maybe we just didn't need it because we were metabolically healthy in the past (we certainly aren't now!) & were not subject to lots of sun exposure.
Anecdotally, I also lived in New Zealand in childhood & suffered terrible sunburn at times & continued to do so throughout adulthood in Scotland & working in the tropics or holidaying in southern Europe. I grew up with a 'perfect' plant-based diet until my early 40s (& have health problems to show for it). I went mostly plant-free about 5 years ago & my ability to cope with sun exposure has never been so good. I do burn but nowhere near as badly as I used to.
Great to see relevant shorter segments for those of us with limited time.
yes
I went Keto 2 years ago and then Ketovore 1 year ago and my sun tolerance (and not getting burned) went up. I actually crave sunshine and feel great. I used to avoid the summer sun and now I love it. My experience is simply that you don't get burned even when in hot midday summer sun. I was quite amazed.
I am zero carb and consume no seed oils, sugars, carbs nor processed foods - Only meat and fat (nose to tail).
That's the proper human diet.
Ketovore is such a funny word, since it implies "eating ketones" even if it means halfway between a pure animal-based die and an unrestricted ketogenic diet.
I don’t eat meat, try and prioritise fruit, and same; love the sun and don’t get burnt.
Tim Spector of the ZOE program, in his Twins study, found there is no one perfect diet. Diff. diets affect diff. people differently. The key is to find what works for YOU!@@Matto_Harvo
There are some awesome doctors, scientists, and journos in the low carb sphere. Mason is among the top, as well as Bikman. They're brilliant people with the knowledge to save millions, the desire to spread that knowledge to anyone who seeks it, and the gift of being able to communicate that knowledge in an approachable manner.
Carnivore for 5 months prior to a San Diego summer. Surf, swim, run regularly in the sun. One day, got caught up at the beach for 2 + hours (unplanned) no sun screen, zero sun burn at all.
Dr Mason amazes me every lecture by how easy and fun he delivers information
It's an interesting topic. Where do animals get their vit D from? And fish, for that matter, does UVB penetrate water? Why were almost all covid patients vit D deprived? Why were people of color over-represented in the hospital intakes? Doesn't the sun also produce nitric oxide for us? How much do we really know of the processes going on when we're out in the sun?
We should get something straight: sunlight is life.
one of our sources of supplemental vitamin d3 was (not sure these days) from sheep's wool. So animals can make d3 from hair/fur, skin or if carnivores, from food. Fish get vitamin d from plankton who get their vitamin d from the sun and are very very good at the process of making this vitamin.
Concerning patients with low vit D. He talks exactly about that. People with large BMI were also at considerably higher risk. Since vit D is fat soluble one can argue that the same intake of vitamin D manifests itself in lower blood values in people with large BMI. And large BMI correlates with poor metabolic health.
You are absolutely correct that we can synthesise nitric oxide from the sun which has significant health benefits - this however is produced by UV-A rather than UV-B which stimulates vitamin D production -- all covered in this video - ua-cam.com/video/Kvh4D_osFXs/v-deo.html
@@FedorBP But this is also an association only.
The real question is whether it s the obesity which lowers vit D in the blood stream, or rather the same condition which has caused obesity is also what is causing vit D deficiency. I would bet the later (dietary sugar and subsequent high insulin being the most suspicious)...
I don't get sunburned anymore, 18 months keto, heading towards carnivore. I do limit my sun but even if I overdo it, I still just redden and then that tans. Interesting talk, thank you!
Me too. Sometimes I'm a red lobster, but then it turns tan. Never burns.
Many people don't burn. People with darker skin. White people with darker skin don't really burn. What shade of white dude are you?
Brilliant as always. I spent 6 weeks on the sun in northern hemisphere and got back with highest vitamin D levels ever in my life and a significantly reduced cholesterol levels. So yes, it makes sense.
Man, he brings a lot of useful info.
Dr. Mason is when a doctor is also a scientist.
My favorite doctor alongside dr.Andrew Kaufman
I believe in Vitamin D but I do not have access to sunlight and most people don't. I work 12+ hours a day - not by choice - and I live far north. Supplementation is fine for me right now thank you very much.
Have you watched the video? He clearly states that getting the vit.D one needs is much less related to sunlight exposure than people give it credit for. It helps, but it's not ultimately needed. If your diet is right, you won't be needing that much sun... or supplementation.
Yes. I am one of them. Since I quit seed oils and improved my Omega 6 to Omega 3 ratio, I don't need to use any sunscreen at all. I live in Gold Coast
This is my experience. I used to fear getting burned and now I go in the hot midday Qld summer sun and simply go brown with no burning. Ketovore makes you sun tolerant.
sounds great. i am having olive oil instead of butter and lard to see if my psoriasis improves. when you quit seed oils, did you even quit olive oil?
How did ya go about fixing that ratio specifically?
I also experienced this, also on the Gold Coast and I try to spend at least half an hour a day in the sun now since last year June.
@@DaKeezl I quit all oils plant oils, including Avo, Olive & Coconut. Dr Mason has a talk on how plant oils are slightly different to animal oils, search "Differences between phytosterols with different structures in regulating cholesterol synthesis, transport and metabolism in Caco-2 cells"
Very interesting. So you don’t need sunlight to maintain healthy vitamin D levels. What about the other benefits of sunlight, for example, increasing serotonin, treating some skin conditions, and generating nitrous oxide. Are these still valid, or do we need to also rethink them?
Maybe we don’t need much d3 if it’s natural (from diet and from the Sun) but for sure we need lots of sunshine.
There is no doubt there are other benefits of sunlight exposure, mainly relating to nitric oxide. I discuss that in this older lecture - ua-cam.com/video/Kvh4D_osFXs/v-deo.html. (also circadian entrainment is also hugely beneficial).
Good question, to me the vitamin D from supplements to treat Covid initially seem positive, but subsequent looks were not so positive. What seem to be the positive affect was the exposure to sunlight, and the things you talked about, including melatonin at the myocardial level.
However, the larger point of this presentation to me is the idea of supplements. On the one hand, unhealthy people take supplements to be healthy and the research on that does not bear out supplements work. The question is do metabolically healthy people need to be taking supplements and I think Dr. Paul is saying vitamin D may not be needed for people with healthy diets and lifestyles.
Yes you do. You need both.
And for intra cellular melatonin
I would add that whilst it might not be necessary to get your Vitamin D from the sun. The Sun also provides other important benefits such as circadian rhythm regulation, sleep, increases in nitric oxide. improvements in mental health and the list goes on.
Dr. Mason doesn't negate that, he actually has talked about the subject many times, mentioning all these points in fact. Sunlight is great for us in many ways, really.
Case here is that he just doesn't overstate the role of sunlight in getting the actual vitamin D we need like many people do.
I am a redhead/fair skinned, this feature evolved in humans living in the high latitudes in europe where extra absorption of of sunlight was an evolutionary advantage (Via D maybe only one of many advantages). Too much sunlight for redheads is bad, as I live in Sydney and spent my childhood outdoors, I have had many skin cancers burnt off/cut out over the years. My siblings with blond hair and darker skin eating the same diet (included margarine) do not suffer from skin cancers. The benefits/risks of sun exposure are complex and even with the risk of more skin cancers I still get 10/15 minutes of sunlight in the middle of the day when I can.
This guy is very good at explaining stuff. I was extremely confused by other people who claimed it's rat poison
Sunshine is part of a "healthy" lifestyle IMO
I agree. Just not overhead sun that will burn you.
I saw a video just two days ago talking about the bullet holes in planes were misinterpreted by engineers due to 'survivorship bias'. I got that one correct...
Paul Mason does it again!!! What an Amazing Doc 😂👍
Beautiful and thought provoking talk.
It could be like vitamin C. Very tiny amounts go a long way in a healthy carnivore human. A human that doesn't consume mineral-sucking phytates, for example.
It seems that it is specifically sugar what depletes vit D (and vit D being able to counteract to some degree the damage done by sugar).
That's exactly what I think. The level "number" required for carb eaters is different from that of carnivores/ low-carbers.
Interesting presentation. No mention however that the majority of people are Vit D deficient when tested, so this potentially implies two things. One that people do not get the full body exposure to sunlight that they used to, and second, that diet alone is not delivering the goods. P.S. Begs the question: are the defined levels for Vit D deficiency actually correct?
Interesting proposition. Counter-point: sunlight is a requirement of a heathy lifestyle
Sunlight and UV provides more to the skin and body than just vitamin d synthesis
Agreed. While bodies shield us from the more harmful spectrum of radiation but rely on the near infrared rays for circadian rhythm, switching back and forth from the pineal producing melatonin at night to the mitochondria producing it during the day.
Sunlight is more natural to the eyes while unnatural LEDs and flourescents are harming our health.
Sun bathing used to be considered healthy before so called experts started fear mongering about cancer. What could be more natural than sunshine?
Adorable and brilliant as usual.
Very good and informative presentation as always, thank you Paul Mason … ❤
Left out much of the beneficial and necessary effects.
All I know is before I supplimented with vitamin d i would get 2 or 3 bad colds a year but since taking 20000 iu a day I have not been sick In 5 years nothing else has changed including my weight.
This sounds amazing to me... I get sick almost weekly for the past 4 months and it's really making me go insane.... Meanwhile everyone else is fine ... I just order 50k IU to take weekly so I'm gonna see if that helps... I have a new born so I'm sure he is sucking the vitamin d stored out of me and plus we r indoors a lot
@1TLA7 good luck I suggest you take zinc and magnesium glycinate as well.
This sounds very eye opening and does make sense but also raises one question for me: If not for low levels of vit D, why are people more susceptible for sickness at the end of winter?
Or is it only the part of population that eats (mostly) vegetable oil based diet that get more susceptible?
Studies have shown Vit D is important in immune function, and on a cellular level.
Vit D produced within the cell is likely superior.
In a similar manner, melatonin is produced in the mitochondria when exposed to near infrared light. Being an antioxidant, this can help combat reactive oxygen species. This is in much larger quantities and more effective than the melatonin produced by your pineal gland.
Given how low risk even milligrams of daily vitamin D3 seem to be, and of the potential benefits, I'm not going to stop microgram level supplementation anytime soon. The discussion around it is interesting though, and likely the purpose of the talk/video, rather than convincing people to stop supplementing.
Don't forget one thing: the Inuit diet is fructose-free. Inuits don't have to fight with excessive fructose intake.
(btw their blood sugar levels are perfectly fine)
I can't stop laughing. Do you seriously believe your own bullshit? Inuit blood sugar levels are perfectly fine? Inuits have historically been the shortest-living and most disease-ridden populations on the entire planet by a wide margin. And no, it's not because of "Western diet", it's their traditional diet which has historically led to those abysmal outcomes. In fact, the opposite is true: more access to "Western" foods has drastically served to improve their health. Get a grip.
*_«These data show high CHD and stroke prevalence in Alaska Eskimos, despite low average LDL-C and high HDL-C. Hypertension and high LDL-C were independent correlates; identifying these risk factors early and treating to target is recommended.»_*
*_«The current belief that the Inuit are protected from CVD is seriously questioned by the results of the present study. Considering the extremely high prevalence of CVD risk factors, a population-based intervention reinforced for women is urgently needed to reduce their risk.»_*
*_«The data collected through this new investigation shows that Eskimos do have a similar prevalence of CAD to non-Eskimo populations, and in fact, they have very high rates of mortality due to cerebrovascular events (strokes). Overall, their life expectancy is approximately 10 years less than the typical Danish population and their overall mortality is twice as high as that of non-Eskimo populations.»_*
*_«“Considering the dismal health status of Eskimos, it is remarkable that instead of labeling their diet as dangerous to health, a hypothesis has been construed that dietary intake of marine fats prevents CAD and reduces atherosclerotic burden,” remarks Dr. Fodor.»_*
*_«The mortality from all cardiovascular diseases combined is not lower among the Inuit than in white comparison populations. If the mortality from IHD is low, it seems not to be associated with a low prevalence of general atherosclerosis. A decreasing trend in mortality from IHD in Inuit populations undergoing rapid westernization supports the need for a critical rethinking of cardiovascular epidemiology among the Inuit and the role of a marine diet in this population.»_*
That’s information I’ve never heard before! Good to know! 👍
at 2:47, dr mason seems to imply that the synthesis of vit d uses up and reduces the level of cholesterol. considering that vit d is measured in micro-grams, this doesn't make sense. removing micro grams of cholesterol should not make much difference to the amount of cholesterol in total.
there's almost nothing he is saying here that is accurate on vitamin d, it's like he just threw some shite together because that's what he believes.
That was eye opening!
i love thinking differently. I also love thinking quantitatively. The argument that people in sunny areas have lower cholesterol because of synthesis of Vit D is most likely garbage. GFirst, between 5..7g of chol are turned over by the body without external supply of it, that is, the body maintains that throughput, and makes 1g to replace the loss. Vit D is FAR LESS by weight. Conclusion. hose people have a completely different set point for chol, not the direct causality sun -> vit D, but because lide in these sunny areas is very different. Those other differences are the important ones: more antioxidants, more movement, less cellular damage, hence less need for the bodies garbage collecting system (==cholesterol)
I do feel he’s undershot the truth about sun’s primary hypothesis position as a highly necessary and beneficial aspect of metabolic and hormonal health.
Other talks list more cellular effect pathways of vitamin D.
While the amount of D in foods does seem to be up to larger debate than I’d seen, I still don’t buy that little sun and just the right foods is the ideal solution, at all.
Evolutionary framework has to undergird. He mentioned plankton using vitamin D as sunscreen, but still adopts the “the sun is damaging” motif.
Seems like a thin motif to me.
Not all sun is damaging. UV-A which stimulates the production of nitric oxide is quite beneficial. Unfortunately I was just asked to speak for 5 minutues, and I was getting the 'your time is up' signal from the back as I was about to discuss nitric oxide.
@@drpaulmasonMD Glad you replied to this excellent comment.
Not only has he "undershot the truth", he's a clueless moron with zero idea what he's talking about.
@@drpaulmasonMD:
So you decided, "hmm, how can I cram as much as possible of the diametric opposite of the truth into this 5-minute presentation?"; nice going, well done; you certainly achieved your objective.
I would disagree with the statement that Vit D is a "sunscreen". I believe it is melanin ( derived from an amino acid, not a fat) that is the sunscreen. I am very happy to hear a counter argument.
Thought the same!
Thank you
All this is great. But what should we do with dr John Campbell and his reviewing of vitd sypplementation studies and the huge health benefits?? Especially in dementia and Alzheimer's
Completely ignores all the other reasons why we need direct sunlight exposure. Regulating biorhythms, positive effects on mental health, etc. Also, humans lived outside for most of our history, so why didn’t our species die of skin cancer if sunlight were so bad for us?
His theory is a huge stretch. Seems like he confused vitamin D with melanin. As vitamin D synthesis drops after melanin production kicks in. So if you are tanned you produce less vitamin D.
@@NataliaKarnaukh not really … you just need to be in the sun a bit longer to keep approximately the same levels …
Paul’s talk was targeted to D3 specifically - not total sunlight exposure benefits.
His lengthier videos contain much more data. Sunlight has many benefits for optimal human functioning… getting a sunburn is detrimental to humans health.
Very nice, thank you

Im a carnivore a year, keto 8 yrs, NO seed oils but I havent seen the sun in 10 yrs. I wonder alot about this Vitamin D. I take 5000 IU a day but often wonder if its enough. Thank you for your video.
Supplemental dose of vitamin D3 is 600-800 IU /day (NIH,America). Maximum tolerable dose is 4000 IU/day.Check your Vitamin D level in blood which should be 50-125 nmol/L . Blessed be.
@@mithidas4295 thank you!
I also take 5000 IU a day
Got my blood tested and the results were:

It’s Above the ”optimum levels” but it’s still in the range which you can aquire naturally by the sun.
Toxic levels are 375 btw. So I will continue taking 5000 IU and cut down a bit when I’m out in the sun.

I'm Carnivore 8 months, but i do take vitamin d supplements because here in the uk, the sun is a rare thing to be seen, the cloud's are most common sight.
I've been listening to LCDU and Dr. Mason for some time. Great information. I am wondering if there are any studies on Cholesterol levels and low Vitamin D. From what I understand, our body will make the level of Cholesterol it thinks it needs. Vitamin D is extremely important for overall health and sun exposure to the cholesterol in our cells produce Vit. D. Most of us are Vit. D deficient. Is it possible that the high cholesterol in many people is the attempt of the body to generate more Vit. D?
Very interesting talk, thank you!
OMG, this makes so much sense why I don't burn anymore!
I used to get bad, really bad sunburns from as little as 30 minutes in the sun. When fasting or on a carnivore diet my resistance goes up to two, even three hours in the sun without a burn.
Think you could find dozens of scientists who would say he is talking a load of rubbish.
amazing, so intelligent , a complex idea digested and enjoyed :-)
Omg this makes so much sense
I am in my early 60s, and in addition to eating a keto/carnivore diet for several years, I have also supplemented with 8,000 IU of vit D3 daily for about 2 years, yet when I recently got blood tests that included vitamin D, 25-Hydroxy, my level was 42.9 ng/mL on a scale of 30.0 - 100.0 so not even in the upper half of the normal range. Also, I work outdoors in the subtropical state of Florida in the US, though I do cover up and wear sunscreen to avoid skin aging and skin cancer.
Supplemental dose of vitamin D3 is 600 IU/day(NIH,America).In spite of higher dose your D3 level is within normal range.Some factors must be playing.What other medicines are you taking?
Did you take K2 too? If not then you can be happy with your 42.9ng/ML. You need K2 for better absorption
@@mithidas4295 Perhaps the D3 supplements are not that effective, no matter what your dose.
What is your bmi?? and weight?
The sunscreen/cover prevents your body from producing vit D. It does seem common for very low levels of vitD in populations of sunny places where sun exposure is avoided, or screened, with low animal fat diets providing hardly any either.
Very unique perspective
quite insightful 7 mins on Vit D3. thanks Doc
No it's not. It's lop sided.
I always sufferd with winter depressions, tought it run in the family until i learned that i had Lipedema and a study been done that showed that the patients in the study had low vitamin D. I love the din and eat vitamin d but still get realy low in winter time.
You may want to try to use a SAD light during the winter months. Look into it.
I can see he hasn’t seen sunshine in years 🤣
Im always curious how ancient peasants in Europe fared without any sunscreen yet prominent exposure to UV rays, let alone those exported to colonial areas to work the fields there for example the Portuguese used their jewish population on their colonial islands. Would the skins melatonin after prolonged exposure be good enough? Does sun burn help the skin to more rapidly protect itself? Did they use mud or other forms of protection?
If only Paul would apply the same scientific scepticism to the ‘science’ of virology.
I took a vitamin D supplement for a few months this winter, because my levels were a bit low, I wasn't getting much sunlight, and I thought it couldn't hurt. I ended up with a low platelet count. Apparently vitamin D supplements lower platelet count, but my doctor didn't tell me this when she recommended a vitamin D supplement while my platelet count was near the bottom of the reference range.
" According to the results of this study, lower vitamin D
levels will cause higher platelet counts in people with normal
calcium and magnesium levels. " As per - cms.galenos.com.tr/Uploads/Article_40039/GMJ-62-174-En.pdf
Wow. Thanks for sharing this!
Three days ago I purchased vit D for the first time in my life. I'm super lean, know nothing about it and only did it on instinct. I'm in the zone!
hi bro , how do you feel on it ?
I want to hear more!
It would have been constructive to hear Dr Mason's opinion of an adequate range of blood vitamin D levels.
A high vitamin D level is an indicator of good metabolic health. We can get enough from animal foods. You don’t need to rely on the sun to get your vitamin D. Don’t get your vitamin D from a bottle. Also, don’t be fat.
Just because vitamin D may also be a good sunscreen doesn't mean that getting it by all 3 ways (diet, sunshine, and supplements) isn't beneficial for other reasons.
I asked a long time ago if vitamin D production from sunlight exposure was a kind of hormesis
So other than as a sunscreen and doing something to make healthy bones, does vitamin D have any other functions? And why those two very different functions (sunscreen and bone health)?
I am confused now. Other keto doctors like dr. Berg, dr. Berry say that supplementation of vitamin D3 is essential for good health because this vitamin take part in multiple reactions in the body (not only for sunscreen or rickets). Now dr. Mason says that supplementation is not necessary. Hmmmm.
IF you get enough out of your diet. And that is really hard with the current foods available. And therefore keep supplementing.
If you just eat human food (Ketovore) you don't need supplements. Paleo man didn't have D3+K2 pills.... We have the same genetics as we did 2 million years ago. Don't think so hard.
Eric Berg is a chiropractor and a Scientologist who just repeats things from others and sells questionable, ineffective supplements. Unsubscribe from him.
I believe it is esdential for good health but dont just blindley take a suppliment, get your levels tested to know for sure.
I did try it. And now I know it’s true. Vitamin D is not The Sun hormone.
Interesting conjecture. I'm not going to hold my breath waiting for research into it though, probably won't happen in my lifetime. On the sun-burn side, I had never thought about it until now. After 6 years low-carb then keto, I can't recall a single incident of sun-burn. But shortly before starting, I watched a tri-athlon in Provence in the month of May, I think. I had forgotten to bring a cap and got well sun-burned. It was quite embarrassing because I had to renew my passport and the photo was taken with my sun-burn... A couple of weeks ago I had a one day stopover in Abu Dhabi and spent the time walking around between the city centre and the beaches. It was 39°C and I was just stupidly wearing a T shirt. Back home I realised I didn't get sun-burned, which vaguely surprised me, but hadn't thought about it until viewing this video. Maybe there's something in his conjecture - at least for sun-burn.
Interesting!
I have vitiligo, very patchy all over, European ancestry. I am on basically high protein, healthy fats, few vegetables and nuts,
13 hr intermittent fasting.
Vitamin levels 70+.
Can I do sun?
Until I started taking Vit. D3 supplement (5k IU daily) I had 3 mild flus and 1 severe cold yearly. In the 20 years since then none; except c-vid.
Thanks Doc
Not sure what the real conclusions are though, lot of association no causation
I got sunburn recently, even after no seedoils and lots of meat for years.
As if the effect goes away after a few years
Thanks Paul. Are you aware of denaturing / break down or reduction in pre-formed Vitamin D from animal foods e.g. beef tallow on heating or cooking?
Dr. Mason just did a slam dunk on the normie view of vit D and I’m all for it.
Next up: we need your take on vit A and copper toxicity from excessive organ meat consumption 😅
I eat organs every week and soon having my OMAD liver mince. Bloods and Lipids perfect.
and from pills too. I am very confused about vit. A. Even more than d3 alone. Would like dr Mason checked / debate Morley Robins on retinol & d3.
Hmm.. I think it's scary how people can change their beliefs after a 5 minute talk of one person expressing his thoughts without showing any bit of evidence. It's a research and discussion subject at best, I don't see the slam dunk.
Vit-D is a sun screen
Protects from Covid
Help me understand, Inuit eat fish which is high in vitamin D, if you don't eat fish, then all I am left with is eggs and not much else, meat, poultry and cheese are very low in vitamin D.
Vitamin D does so much more
A very important point to consider is that our nutritional databases are possibly significantly underestimating the amount of vitamin D in terrestrial animal source foods. Due to not accounting for the Calcifediol content in said sources. the form which our body turn vitamin d3, d2 and alike into in order for it to use it. And it is known that Calcifediol has a much greater affect on blood vitamin d levels tham d3. There is actually some data on the content of Calcifediol in terrestrial animal source foods. And there is a paper which attempts to calculate the vitamin d content of such foods, adjusting for the Calcifediol content and it’s average affect on blood levels of vitamin d. it estimated that the actual vitamin d content was much higher than the current databases report. offering a potential explanation for how people going on low carb or even carnivore diets aren’t lacking in vitamin d. As well as explaining the discrepancy between apparent vitamin d consumption and lack of deficiency in the general population. Which was the main focus of the paper.
