🇨🇦Canadian Pharmacist here: Great presentation, excellent explanation, keep up the great work. Vitamin D deficiency is definitely common in Canada and it plays such an important role in the body. Many people in Canada are deficient but never get a chance to find out as testing is not covered in every province. Excellent content here. Very timely as well.
It's great to hear a doctor with outstanding nutritional knowledge. I have low vitamin D and CKD, I'm thinking they go hand-in-hand. COVID hit me harder than most. Supplements don't seem to help, trying to figure out which will. Thank you for the info, doc!
Does K2 help prevent negative side effects of hypercalcemia when supplementing with large doses of Vitamin D? If so, is there a rule of thumb or good ratio to follow?
Yes it does, and the usual recommended ratio is for every 10,000 IU of D3 you need 100 mcg (microgram) of K2. Makes sure the K2 is in the all-trans MK-7 form.
That was incredible! This has helped me study and revise for a nutrition exam. It was explained so well, and I feel like I am finally understanding the concept. Thank you so very much
Known as the sunshine vitamin, vitamin D is produced by the body in response to skin being exposed to sunlight. It is also occurs naturally in a few foods -- including some fish, fish liver oils, and egg yolks -- and in fortified dairy and grain products.👏
There’s a lot of people recommending a much higher level of supplementation, Dr. Rhonda Patrick takes 5000 IU per day, Dr. Eric Berg recommends 10,000 IU per day. Make sure to take K2 (MK7) at same time as VitD to make sure the increased calcium absorption is going to the right places and not the wrong places with negative side effects.
@@joshposh9789 dr chris Kresser also recommends 5-10k IU for vitamin D, I just read that in his email newsletter 1-2 days ago just FYI. He has been interviewed on Joe Rogan podcast several times although idk if he spoke about vit D on those shows
@@joshposh9789 Professor Roger Seheult, MD also recommends much higher levels, and he teaches medicine to doctors! ua-cam.com/video/ha2mLz-Xdpg/v-deo.html
Matt, Vit D is supposed to aid calcium absorption in the system - so why would excessive Vit D (over exposure on the whiteboard) once again result in Exttra calcium floating around in the blood OR result in Osteomalacia which are supposed to be the result of its deficiency ?
I was vitamin D deficient at 30 nmol/L. I took 7,000 IU daily to raise serum D3 with monthly readings of 70, 88, 128 and most recently 145 nmol/L, within optimal range. I also take vitamin K2 to prevent soft-tissue calcification. Official dosages are only minimum requirements to prevent weak bones, ignoring many other physiological needs (discovered in recent research); hence too low for optimal health. The optimal levels recommended by Dr Seheult is 126-175 nmol/L (including Covid-19 prophylaxis). Levels below 125 nmol/L are regarded as sub-optimal. I am reducing my summer dosage to 4,000-5,000 IU daily to see whether it is sufficient to maintain optimal levels above 125 nmol/L.
@@montyi8 They shouldn't be, I recently spent around 70R$ (~14 US dollars) in Brazil for my blood test which included vitamin D among a bunch of other things, expensive healthcare is usually a result of over regulation which is very common in the field.
I trust this kind of hardworking Dr, he is super hard working I swear he never get tired of writing even though he have been writing so many yrs during his training n after.. N his body tells everything how hard working he is. And in indy most dr body wud store n accumulate too much fats especially in their abs n no shape n dull n lifeless skin, they don't groom well their face n looks untidy with beard n moustache.. Who doesn't look after their own body I'm not sure how they will perform or how many percentage they will give effort to their patient..
Research suggests it's VERY difficult to raise serum 25-hydroxy vitamin D above the reference normal upper limit (100 ng/mL). Research also shows that for both influenza and COVID-19 the greatest protection from infection (double that of the lower, 30 ng/mL limit of reference "normal") is achieved with blood levels between 55 and 100. We have seen zero reports of vitamin D toxicity from taking ordinary vitamin D supplements regardless of dosage. The reports of toxicity I've seen involved highly concentrated D products (e.g., concentrated D liquid drops) or defective products in which the vitamin was accidentally dispensed without dilution.
Can one experience muscle and bone pain initially after taking vitamin d3? Magnesium is taken together with the vitamin d3. Dosage of the vitamin d3 is only 3000 to 4000iu per day
Thanks you for the clear presentation! I was consulting the literature based on the dosage given in your presentation and wondered. A dosage of 2000-3000 IU is not that uncommon and is seen in several studies. Also, upper limits of vitd3 for toxicity are seen in cases with a daily intake of 30000 and more. And another factor is chronic intake. Why do you think de advised data should be 600 for adults and do you feel this is enough according to your clinical experience? How much exposure do we have sitting in the sun for a whole day? Thank you :)
Hi I just had my Vit D tested amongst many other things. I’ve taken 10,000ius for ten years with Vit k2mk7. My liver, kidney, mag, B12 were all good. But my Vit D came in at a whopping 300!! Could this just be because I took my supplement a few hours before? I feel great I’ve taken this amount with no issues for a decade. I don’t want to stop taking it. Thx
Is that nanomols per milliliter like in Europe or nanograms like in the US? I'm currently taking 35k IU daily in an attempt to get my blood level between 125 to 175 ng/ml in my blood to help heal spinal pain. If you are at 300 nmol, you would be about 120 ng/ml which should be fine. According to some people, lifeguards get that high naturally.
I'd love an update on this, and if it's not too much to ask your weight lol, I know it's impolite to ask but dosage really is weight dependent and I'd love to up mine to 10000IU too 😅
Very good information on synthesis of vitamin D. However I disagree on the recommended amounts of vitamin D3 supplements. We need more when not getting much UVB rays.
How come supplemental D3 is associated with calcium build up in the arteries, kidneys etc requiring K2 to redirect it to the bones.. but I am assuming that D made via UV-light doesn't result in this pathology? The quoted amounts for supplementation are very low. Apparently we produce between 25,000-50,000 IU with proper UV-exposure. 600IU is a very small amount for someone not getting adequate sunlight.
Wow excellent video Dr. Mike you explained it incredibly well! The examples you used and the way you broke it down made it easy to understand and remember! Thank you
I'm taking magnesium rich food/the occasional magnesium tablet for high blood pressure, which also apparently directs calcium from bloodstream to the bones. I am currently able to keep my diastolic uner 90 which the doc says means i dont need to go on bp tablets. To get to this point i think cutting out caffeine and salt from the diet helped bring my diastolic down some.
Its an awesome video but i have some questions: 1. If we only have PTH we will still be taking phosphate from the bone along with calcium so why isnt the bond persisting? Why isnt the phosphate excreted in the normal times when calcium is low? Why isnt the phosphate reabsorbed from kidney when PTH levels are high? 9:25 2. We are given calcium supplement along with vitamin d tablets. Arent we supposed to be given phosphate supplement instead since its the one being excreted?
So, I understand it'd be difficult to say definitively, but will taking a multivitamin a day, curb this deficiency? Presuming a person is generally active with a day job; can simply taking a multivitamin a day cause an overabundance? Is there any way to tell without regular blood work or simply waiting for a symptom?
Very clear and concise lecture especially during this time when numerous "doctors" are suggesting huge amounts of Vitamin D supplementation. Thanks for posting.
Hey Doc thanx for such a detailed info on Vit. D, I do hav a question though...i read that scientists recently discovered nitric oxide activity in the blood after sunlight exposure. Is this something that can be achieved via supplementation also?

... much more problematic and even more likely is to be deficient in Vit D .. 50-100ng/ml is the goal in the bloodserum ... with less than 5000 IU D3/DAY you are not able to raise the level at all ... Magnesium plays a keyrole in the conversion in liver and kidney ... tge lack of magnesium is therefore a much bigger problem than to little calcium (what is kept in the bones by K2 - so no hypercalcemy appears if there is enough K2 in rhe game even with higher dosage of D3 !! ) ... the 800 IU / day for an adult was a COMMA-MISTAKE as "we" know meanwhile ... it should be 8.000 IU / day what obviously this doctor doesn't know even a little logic thought comparing a babies weight with an adult shows clearly a factor 10 !! ... it is a disgrace how much MISSINFORMATION is going around when it comes to Vitamin D3 - "UNFORTUNATLY" (for those who make their income with sick people) a good Vitamin D level 50-100 ng/ml keeps people mostly healthy ... a real nightmare for pharma and doctors ... think about it ... something very fishy is going on here ... btw, I take 10000 IU/day since years and feel very good and nearly never ill anymore in contrast to the time before ... 2 colds a year ... now ZERO !!
Sir I'm D vitamin deficiency 6 . I have body burning and itches pains. Weekness. Headache. Tiding. Hair loss. Whight again. Throat pain jaw pain. Extra helth issues. Im consultant Doctor suggested supplements Rise D . Calcium please suggest me
I have dealt with the same issue and my symptoms have actually came back. You need to go to the doctor and they will prescribe you 50,000 IU of vitamin D too and you’re going to have to take it for a couple months to get yourself back. But like he said you’re also are going to have to supplement with calcium magnesium and B12 as well as K2
Basically imagine they are stored in two tanks in your body. Both full is good . 25 tank full and 1,25 tank low means that you have a problem with your kidneys converting to active molecule. 25 tank low and 1,25 tank full means that you have good active molecule, kidneys converting well. But once the 25 tank becomes empty the kidneys wont have any 25 to convert to 1,25. So you need to refill the 25 tank. Meaning take more vitamin D. Im not a doctor but just my thoughts.
1,25 is the most refined and most bioactive one, the body will try and maintain it at higher level even as 25-OH (1,25 precursor) runs low. Most likely reason is low 25-OH precursor which is D3 (and D2) so very likely to be low D3 reserves, less likely bad liver metabolism or magnesium deficiency.
How long should we stay in sunlight? Do we have to be naked or face, arms and hands are enough to be exposed? What is the best time to be exposed in sunlight?
Not all sunlight will stimulate D3 synthesis within the skin. Your skin specifically needs to be exposed to UVB radiation to synthesise D3. A general rule of thumb is if your shadow is shorter than your height (i.e. the sun is almost directly above you), you'll be receiving UVB radiation. If your shadow is long (i.e. the sun is low in the sky like at sunset or during winter), all you'll be exposed to is UVA and will not synthesise vitamin D3. In terms of how long you need to be in the sun unprotected (shorts, t-shirt without sunscreen), it is actually not too long. You can safely be outdoors for 20 minutes at midday. After this, put a hat and sunscreen on. If you're an office worker and only see the sun at its lowest points during the day (e.g. early morning/evening), you might like to take a D3 supplement. I personally take 10,000IU of D3 per day along with 360mcg of vitamin K2 (MK7). I replied to this video with this comment (below) which explains my reasoning. I hope this helps: ------ Another interesting fact is they are finding not all 25(OH)D is activated via the kidneys and actually quite a lot is activated by a whole range of cells within the body. Therefore, vitamin D is important not just for calcium absorption. Another fun fact is it is assumed the milk from breastfeeding mothers doesn't have vitamin D in it. However, when a mother is supplemented with around 6,400IU of D3 per day, her breast milk will contain enough D3 for her nursing baby. So I wonder if the 600IU RDI we're all told about by the experts is actually adequate? In terms of evolution, it is clearly inadequate considering modern breastmilk not containing enough of it. A dose of 600IU may be enough for the body to mineralise the bones and undertake other basic functions (e.g. maintaining blood calcium levels), but not optimal considering all the other functions which rely on vitamin D in the body. We never took supplements back when we were in the caves, yet against all odds we evolved without rickets. Back then, human beings were out in the sun all day, almost naked, receiving a lot more D3 than "600IU". I reckon the 6,400IU dose is closer to what we actually need. A mother's breastmilk is evidence of that (i.e. she is able to fulfill all of her biological requirements in which D3 is needed, with enough left over for baby).
I cannot have Vid D without calcium. Why?? My vit d is extremelly low. And my urologist forbids me to take calciun cause I get oxalate calcium stones. can someine help?
Then it means low calcium is good in terms of vit d conversion into calciteriol. Isn’t it the other way round ?if u take calcium as a supplement that means calciteriol will not be activated is isn’t it?
👍 Excellent video - very informative. Thank you for making the video. The only misinformation is they are supposed to be abdominal "groan" and psychic "moan" and not the other way. Understandably once the video is published, it's a pain (psychological of course :) to redo it all over for the error ( I've experienced it myself when making an educational video for students with an inadvertent error due to limited time and diminishing energy from busy teaching at the end of the day). Nonetheless, I suggest and think it will be helpful to add notes for the correction below the video for viewers. Keep up the good work! 👍👏

And also by exposing mushrooms to the sun it produces vitamin d. Which can be consumed

Magnesium plays a keyrole in the conversion in liver and kidney ... tge lack of magnesium is therefore a much bigger problem than to little calcium (what is kept in the bones by K2 - so no hypercalcemy appears if there is enough K2 in rhe game even with higher dosage of D3 !! ) ... the 800 IU / day for an adult was a COMMA-MISTAKE as "we" know meanwhile ... it should be 8.000 IU / day what obviously this doctor doesn't know even a little logic thought comparing a babies weight with an adult shows clearly a factor 10 !! ... it is a disgrace how much MISSINFORMATION is going around when it comes to Vitamin D3 - "UNFORTUNATLY" (for those who make their income with sick people) a good Vitamin D level 50-100 ng/ml keeps people mostly healthy ... a real nightmare for pharma and doctors ... think about it ... something very fishy is going on here ... btw, I take 10000 IU/day since years and feel very good and nearly never ill anymore in contrast to the time before ... 2 colds a year ... now ZERO !!
Thank you For. Will explained..Good Job
Sir I'm D vitamin deficiency 6 . I have body burning and itches pains. Weekness. Headache. Tiding. Hair loss. Whight again. Throat pain jaw pain. Extra helth issues. Im consultant Doctor suggested supplements Rise D . Calcium please suggest me
I have dealt with the same issue and my symptoms have actually came back. You need to go to the doctor and they will prescribe you 50,000 IU of vitamin D too and you’re going to have to take it for a couple months to get yourself back. But like he said you’re also are going to have to supplement with calcium magnesium and B12 as well as K2
@@dayreese6352 how are now?? Sis
This video is very clear and easy to understand. Thank you! I learned something today!

So what does it mean when your 25-Hydroxy D test shows deficiency but the 1,25 Hydroxy D testing show normal
Basically imagine they are stored in two tanks in your body. Both full is good . 25 tank full and 1,25 tank low means that you have a problem with your kidneys converting to active molecule. 25 tank low and 1,25 tank full means that you have good active molecule, kidneys converting well. But once the 25 tank becomes empty the kidneys wont have any 25 to convert to 1,25. So you need to refill the 25 tank. Meaning take more vitamin D. Im not a doctor but just my thoughts.
1,25 is the most refined and most bioactive one, the body will try and maintain it at higher level even as 25-OH (1,25 precursor) runs low. Most likely reason is low 25-OH precursor which is D3 (and D2) so very likely to be low D3 reserves, less likely bad liver metabolism or magnesium deficiency.
I love your contents, Dr Matt.

How long should we stay in sunlight? Do we have to be naked or face, arms and hands are enough to be exposed?
What is the best time to be exposed in sunlight?
Not all sunlight will stimulate D3 synthesis within the skin. Your skin specifically needs to be exposed to UVB radiation to synthesise D3. A general rule of thumb is if your shadow is shorter than your height (i.e. the sun is almost directly above you), you'll be receiving UVB radiation. If your shadow is long (i.e. the sun is low in the sky like at sunset or during winter), all you'll be exposed to is UVA and will not synthesise vitamin D3.
In terms of how long you need to be in the sun unprotected (shorts, t-shirt without sunscreen), it is actually not too long. You can safely be outdoors for 20 minutes at midday. After this, put a hat and sunscreen on.
If you're an office worker and only see the sun at its lowest points during the day (e.g. early morning/evening), you might like to take a D3 supplement.
I personally take 10,000IU of D3 per day along with 360mcg of vitamin K2 (MK7).
I replied to this video with this comment (below) which explains my reasoning. I hope this helps:
------
Another interesting fact is they are finding not all 25(OH)D is activated via the kidneys and actually quite a lot is activated by a whole range of cells within the body. Therefore, vitamin D is important not just for calcium absorption.
Another fun fact is it is assumed the milk from breastfeeding mothers doesn't have vitamin D in it. However, when a mother is supplemented with around 6,400IU of D3 per day, her breast milk will contain enough D3 for her nursing baby. So I wonder if the 600IU RDI we're all told about by the experts is actually adequate? In terms of evolution, it is clearly inadequate considering modern breastmilk not containing enough of it.
A dose of 600IU may be enough for the body to mineralise the bones and undertake other basic functions (e.g. maintaining blood calcium levels), but not optimal considering all the other functions which rely on vitamin D in the body.
We never took supplements back when we were in the caves, yet against all odds we evolved without rickets. Back then, human beings were out in the sun all day, almost naked, receiving a lot more D3 than "600IU".
I reckon the 6,400IU dose is closer to what we actually need. A mother's breastmilk is evidence of that (i.e. she is able to fulfill all of her biological requirements in which D3 is needed, with enough left over for baby).
In kidney it will be 1,25-Dihydroxycholecalciferol not
1,25-hydroxycholecalciferol

Great job ❤
I cannot have Vid D without calcium. Why?? My vit d is extremelly low. And my urologist forbids me to take calciun cause I get oxalate calcium stones. can someine help?
... because vitamin D activates calcium from the intestine to a particularly high degree.
And think about magnesium and vitamin K2.
Absolutely excellent exposition.
Excellent video Dr! Thank youu :)
Ur fitness level is awesome
Thank you Dr.
Then it means low calcium is good in terms of vit d conversion into calciteriol. Isn’t it the other way round ?if u take calcium as a supplement that means calciteriol will not be activated is isn’t it?
Wow. Fantastic. Thank you
👍 Excellent video - very informative. Thank you for making the video. The only misinformation is they are supposed to be abdominal "groan" and psychic "moan" and not the other way. Understandably once the video is published, it's a pain (psychological of course :) to redo it all over for the error ( I've experienced it myself when making an educational video for students with an inadvertent error due to limited time and diminishing energy from busy teaching at the end of the day). Nonetheless, I suggest and think it will be helpful to add notes for the correction below the video for viewers. Keep up the good work! 👍👏
Getting sun through a window... Are we still able to fully get vitamin d?
