Harris has lost a lot of my interest as it became clear that I have to check a lot of his work to find out if his conclusions were arrived at through a biased lens or if he even did enough research to truly understand what he was investigating.
The answer is he can't be trusted. Every time he touches politics he gets politics experts examining why he's wrong, every time he talks about history he gets people explaing why he's wrong, every time he talks about science he gets people explaining why he is wrong, and every time he does news he has journalists explaining how he has not integrity. He's basically made a whole anti-Harris sub genre of youtube
Thank god the algorithm showed me enough other channels that criticise his “research” and from there on it became apparent how he doesn’t have a critical lens at all to talk about a lot of themes. Only video I would recommend is his McDonald’s ice cream machine video, that’s it. 😅
Harris's videos tend to seek sensationalism as the truth. More entertaining, more $$$. His top touch editing gave him lots of pseudo credibility as that if you present it well, it is more likely more credible. This is an inherited flaw in our race.
If I remember correctly, a lot of these studies just asked people if they took a multivitamin or not. The general lack of effect can largely be explained by not controlling for dose or adherence. If a large percentage of the studies had given subjects the same multivitamin and then asked them to record in a journal if they took it every day the results might be a little more interesting.
I have mitochondria dysfunction. I take many supplements to help with that. If I forget to take them my legs don't work. So I know some supplements are life lines.
Yeah, the topic is too large, they can not study all things at once. They should study them individually for specific purposes. Does vitamin C cures scurvy? Yes. Does green mussel extend life? No. And even in one study there are so many variables, like dosage, length, bioavailability, etc.
One of the things I found most shocking is the fact that there’s apparently anabolic steroids in protein powders. And my biggest worry is the presence of heavy metals in turmeric and other supplements from countries where the soil is rich in lead or where they add it on purpose to make it look more yellow (I don’t know if this is true or not).
Thank you for the insight without the drama. I can't watch Jonny Harris as I always felt like I had to double check all the data after every video to see if the data was correct or if there was an agenda being pushed. As stated more is not always better and I feel like Johnny Harris's channel is just more emotional drama.
More emotional drama vs johnny studies is not a ligitimate reason to dislike him or not watching his videos. Is either you are bias or not. But you cant have to two. Johnny is very good at his craft. 🥱🤷♂️🚶♂️🚶♂️
What stood out to me is how carefully he avoided naming the gigantic corporations behind the supplements and lobbying he was describing. Lots of "these companies" and such. AN entire industry wan indiscriminately smeared by lumping everyone in to one entity.
My bigger concern about the food supplement industry is that they are not lab verified. Even the ones who say they are, mostly checked for common harmful substances only. I remember watching a test, where they tested multiple supplements of the same kind and the results showed that 20% of them didnt even have the stated supplement in them and only 10% of all had the stated amount.
That is, what I have always suspected. You are left to trust the companies. It is not only the farmacy companies, which often are vilified in the circles of with a holistic body view, that are suspect. Follow the money.
For me, supplements are about quality of life and feeling healthier mentally. There are certain supplements that have changed my life. Living forever means nothing if you're miserable during all of it.
@@Coromi1 I'm always hesitant to share because everyone has different needs, but in particular between 1 to 5mg of lithium orotate has been amazing to gently balance my moods without side effects.
@@Coromi1 i can give you a list of mine, maybe it can help. Vitamin D+K2: helped me a lot with mood and winter depression. Down from 1-2 months of depressive episode to just 2-4 weeks per winter. Omega3: i dont know what exactly it is, but i feel generaly better, less knee pain, less dry skin, less dry eye. Note that i NEVER eat fish, so maybe the supplement has a bigger effect on me. Creatine: since i take creatine i finally dream at night/can remember my dreams, which leads to me feeling like i actually slept at night. Before i felt like every day i go to bed tired and wake up 5min later still being tired. HUGE improments regarding quality of life. Also better sleep because i now never sweat in my sleep, before i often woke up a bit sweaty. I assume it is because creatine makes muscles store water, but thats just my guess. My girlfriend takes creatine too and also reports no more sweating at night. She also reports a better feeling of satiety when eating meals. For creatine we can both determine that the changes come from it, or the placebo effect since we both cycled it multiple times, no other changes
please remember that these are my personal experiences and are not representative in ANY way. I only take what i listed there. Additional info: my gf and i both intermittent fast, this might also affect things. We also try to eat balanced meals.
10,000 IU MAY cause harm within the time frame shortly after taking that dose. As the Vitamin D in the bloodstream rises above normal range, it can drive serum calcium to unsafe levels, leading to kidney problems, mental confusion, and even ventricular arrhythmias.

Great post as always and this has helped me a lot. I have been wandering Do you need to take vitamins and minerals every day? I take my vitamin D because I work inside I take my electrolytes but the other things I take every other day and I feel fine. What’s your take on that.?
One thing that comes to mind from this video is the problem of peer review. Many of the issues in the article should have been sorted out before publication. Do we need to actually pay reviewers for a change, on not rely on reviewers giving up their little free time with no direct reward

does anyone have good studies comparing bioacessibility of plant foods? Is the nutritional value really what is given on the package? anyone has studies where plantbased group did not loose weight and still got the benefits?
My respect for you has gone up Physionic. Its not that Johnny's wrong, but it's that its more nuanced than his reporting. As a psychology grad and a tv editor, i see both sides. The reality is things often have to be over simplified for impactful storytelling on video
Another Grade A effort. When you're finally trying to find a topic (instead of having 32 gazillion on your plate), I'd love to hear more about the amount of a dose. I'm a one pill only fool, so I try to get the strongest pills needed. Some questions are: is a little bit better than nothing? All conditions and supplements or only certain ones? Thanks for the clear explanation to a non-scientist.
That study with beta carotene and smokers came out 25 years ago, I remember asking my doctor about it. The dont talk about dose when mentioning multivitamins. Vitamins like Centrum that give RDA amounts would of course be useless. I think dosage is important. Also what about age? It appears now that anti-oxidants aren't needed until you get older. There is too much missing from these studies.
It would nice if conventional doctors would work with their patients do optimize vitamin levels. especially D, magnesium, and K-2 these seem to be what needs to be supplimented to most.
Middle aged and older people are admitted to the Hospital all the time for Hyponatremia, Hypomagnesemia and Hypokalemia. One Over 50 vitamin for these people would likely have prevented hospitalizations. Most doctors don't put their patients on multi vitamins. Many older people are deficient in basic vitamins and are not getting adequate nutrients in their diet.
I also wonder, how many children don't actually get adequate nutrition, as far as micronutrients are concerned. Kids are picky eaters with a strong liking for sweet things anyways. If healthy food isn't actively pushed by concerned parents (or not provided in the first place)... And nobody really checks for these things in children, unless they have a noticable issue. It's not, like they routinely get their blood levels checked, like older adults. I wonder, how many children don't actually develop ideally, physically and mentally, because they're deficient in something or other.
What about older people, is it worth it for them to take a multivitamin as they have less absorption ? ( Edit: according to Web MD there is no evidence they help seniors ) Also there are 3 elements in the multivitamin that are to big to put in the multivitamin like magnesium for example, especially knowing how very important magnesium is and how hard it is to get from real food, after all it was in the well water, not anymore it's not. The multivitamin studies may be flawed perhaps for this one reason ?
I still see the ads for PREVAGEN during rhe news no less even though it's already made the news that the government is suing them for false advertising and fraud! There ought to be a (better) law.
This is my experience also, I have not seen any improvement with vitamins for myself, most of the time. And I have been trying different supplements for decades. I take them from time to time just to make sure I don't develop deficiencies. However, when ever I have been deficient, like once I was deficient with iron, taking it had HUGE effect immediately. My constant tiredness vanished in 3 days when I started taking the iron supplement when before no amount of sleeping helped with the tiredness at all. I was tired no matter how many hours I slept. 3 days of iron and I was once again, energetic myself. So if you are deficient, then they really do work. Also for some reason the only class of supplements which seem to work very well for me are amino acids. Essential amino acids and creatine have had the most dramatic effects. Probably here too deficiency is the reason they work so well for me. Maybe I should eat more meat..
What is logical to me is it everybody’s different and multivitamin is based on an average well they may be getting too much of one and not enough of another. I would think everybody should be analyzed for find out which vitamins are really needed in your body and then you just supplement to take care of those but multivitamins know I take them and when I tried to multivitamins, it caused me more problems. I stick with my vitamin C and zinc. B12, I can tell a difference when I take these every other day or so when I don’t, I feel like I need more energy I’ll take my vitamins and I get my energy back that’s my personal opinion personal opinion
Hmmm, this seems like a weird thing to look at. I've never heard anyone say they are taking a multivitamin to prevent cancer. That thought has never crossed my mind.
Soooo if this is not within his domain and he doesn't know how to interpret the studies let alone have the depth of knowledge to analyze the studies properly then I have to ask why is he wasting our time unless he's just answering general questions and at the end tells everyone that he doesn't know what he's doing. One could argue that he doesn't know what he's doing. You see these dietary supplements don't work, That's why my cardiologist prescribed omega-3 ethyl esters and based on what I've read, I'm happily taking 4 grms daily.
Vitamin K2 is showing to have a huge benefit for reducing severe CVD, which this meta analysis did not include. The statement that supplements (let alone vitamins) have no effect on heart disease is easily debunked.
That's a good way, MC. It's true that is a shortcoming of this analysis. I think it would be better to simply look at it in the context provided than to dismiss the whole analysis simply because they limited their scope to a few vitamins, however.
These super duper META studies of everything all at once are worthless.They need to be specific for specific purpose. So generally asking are supplements good for health is meaningless, but is vitamin C good for scurvy is meaningful. And I agree with the previous commenter that vitamin K and Niacin are both good for CVD prevention.@@Physionic
I don’t think any of us are 100% right about it seems as a lot of studies have conflict of interests . So I don’t think either side of the argument will ever be 100% . We will never truly know the industry and how much it is all snake oil or not as much as we like to think we do and will.
You bring up a good point, all kind of factors involved with supplementation. Is it a reliable brand? Was the sup stored and administered correctly? Is the dosage not too low or high? etc.etc. Lots of extra factors to be considered and can effect a study or individual usage.
Great content, Nick! What are your thoughts on Andrew Saul, aka the vitamin guy? It was from him that i learned about niacin supplementation. He has been featured in some of the bigger documentaries,e.g. "Food Inc."
We do not need suplements unless perscribed by a real medical Dr. If you need to take something, one multivitamen/day will do. STOP wasting money on supplements. Unless, in jest, you are aiming to suplement yourself. GREAT CHANNEL!
Would those be the same Medical Doctors who told us that taking a 'covid19' 'vaccine' would prevent infection and transmission of the horrendously lethal virus? Really? The doctors who wore and required masks even though they knew nothing about gas flow through and AROUND masks. Those doctors?
There are so many confounding variables with these large trash can Meta studies that render most useless. Multi vitamin? Which one, what formulation of which vitamins? Argh. Worthless
I think I have malabsorption of nutrients, especially after I turned 60, so have to supplement. When my gums start bleeding, I know I have to supplement with Vit C. My Vit D was 3 instead of 50 - 75 so I take that - I have actively avoided the sun for the past 30 years due to skin cancer. I'm under daily high stress so I take Vit B12 and Niacin. I have fibromyalgia with its accompanying IBS, so I often eat wrongly when I'm not nauseas. I used to be able to get all my nutrients from food, that was in the days when fruit smelled so delicious you couldnt walk past without buying it. I was bursting with energy on food alone, smoothies with celery, brocolli, fruits, oats, nuts and seeds for brunch (not a breakfast person), a massive salad before supper after gym, then something like steamed veggies and a cheeze sauce, chickpea coconut curry or or a chickpea omelette or tofu scramble. Then my partner defrauded me out of my business, and I had to rent out my house and live in my car. So diet was whatever I could get. I developed really poor eating habits, and could not afford any vitamins at that stage, that was a real cheap junk food time. Someone sponsored me a multi vitamin and a probiotic (Efficient Microbes) which was massively helpful in making me feel better and get through those days. My husband takes a multivitamin daily, although as far as I'm aware you should take them after a meal, and he takes them on an empty stomach so I'm not sure if it's doing anything for him or if he just has expensive pee🙄
Why do people take supplements if their levels are already good? Does this mean their levels used to be bad, but now they're good and they just want to make sure they stay good?
The problem with multi-vitamins might be what they don't contain. Vitamin D3, K2, and magnesium for example. Multi-vitamins/minerals could be a basis of a supplement regime. But what about the rest, the things you really are deficient in? I find it hard to belive that supplementing with those things a large percentage of the population is deficient in wouldn't make any difference. Then sometimes supplements has forms of vitamins which are known not to he the best. So, they don't do much good. But mosttly, I think the research being dome is not able to pick up on the effect when there is one. To include 84 insufficient research papers is very likely to produce a null result. It's a qustion og garbage in, garbage iut. It's my belief that a good diet and only those supplements we know isn't covered by that (such as vitamin D) is pretty optimal. And that the multivitamins is just an unneccesary insurance. They do no harm, if well formulated. How many of you have optimal levels of Boron, for example? Or iodine and selenium? Yes, our salt might be ""fortified" with iodine, but not enough, and you probably don't eat enough of sea food, if yiu aren't japanese. Fortification of food is a very bad idea, if you ask me. I would much prefer if each country just gave us a free supplemeent with thoe things. Not everyone eat those fortified foods, you know! Perhaps food labels instead should make us aware of that this food item has been processed to remove these natural vitamins! That would make the producers fix things instead of glossing them over. Forbid food "fortifications"!
Thanks for another great video. What about all the other diseases, Alzheimer's, dementia, diabetes, glaucoma, AMD, etc.? A recent study shows that multivitamins are effective at preventing dementia
Johnny seems to be the kind of guy that googles a few things on the web and forms an opinion. Then he parrots the things he read without really scrutinizing it. This can make you sound smart at the pub or cocktail party. He makes well edited glossy videos that make it sound like he did deep research. However, when you dig into it, he's missed a lot of important nuance and can be misleading.
He has run out of topics to cover…he wants to be the next Vox, but that requires a solid research team…he should have stayed with geopolitics, his strong suit, because geopolitical opinions can’t really be evidence based…but I guess he wants to grow bigger (like all “successfully” UA-camr).
Not a competition. The more who cover topics like this from diff angles incl those w/Nic’s academic/ science background the better. Jake Trans doesn’t always get facts right (or cover all of them) and too often pushes what he’s supposedly calling out.
@@carinaekstrom1 What, you don't want your daily dose of uric, phytic, and oxalic acids? Surely nature wouldn't have put those nutrients in plants if humans didn't need them?
The best way to farm views is to call out popular UA-camrs. You don't even have to make a decent video, just mention a popular name, like Johnny Harris..
I'm sorry but while the basic analysis in this video is great as always, I'm pretty disappointed in the conclusion you draw at the end. The primary issue is this extrapolation that it makes supporting the whole video saying "well supplements basically don't do anything." That is his ultimate takeaway and interpretation of what the study communicates, and that is hopelessly wrong. Vitamins and supplements are not the same thing, and as you point out in the video, the result of this study is pretty expected within the paradigm that supplements absolutely can do very significant things. His conclusion that he tries to draw that supplements are basically meaningless is extremely anti-scientific and is the main problem with his video.
His gun control video from his trip to Switzerland is pretty terrible too. A total misunderstanding of what he was looking at compared to back here in the States. Several of his claims in that video are entirely untrue and based on his biased perception of how the average American owns and uses their firearm. ¯\_(ツ)_/¯
Harris has lost a lot of my interest as it became clear that I have to check a lot of his work to find out if his conclusions were arrived at through a biased lens or if he even did enough research to truly understand what he was investigating.
The answer is he can't be trusted.

( Edit: according to Web MD there is no evidence they help seniors ) Also there are 3 elements in the multivitamin that are to big to put in the multivitamin like magnesium for example, especially knowing how very important magnesium is and how hard it is to get from real food, after all it was in the well water, not anymore it's not. The multivitamin studies may be flawed perhaps for this one reason ?
I still see the ads for PREVAGEN during rhe news no less even though it's already made the news that the government is suing them for false advertising and fraud! There ought to be a (better) law.
This is my experience also, I have not seen any improvement with vitamins for myself, most of the time. And I have been trying different supplements for decades.
I take them from time to time just to make sure I don't develop deficiencies.
However, when ever I have been deficient, like once I was deficient with iron, taking it had HUGE effect immediately.
My constant tiredness vanished in 3 days when I started taking the iron supplement when before no amount of sleeping helped with the tiredness at all. I was tired no matter how many hours I slept. 3 days of iron and I was once again, energetic myself.
So if you are deficient, then they really do work.
Also for some reason the only class of supplements which seem to work very well for me are amino acids.
Essential amino acids and creatine have had the most dramatic effects.
Probably here too deficiency is the reason they work so well for me.
Maybe I should eat more meat..
Great perspective
Yet it's nearly impossible to find a multivitamin that doesn't include Beta-carotene.
Vit D3 and k2 are critical for good immune function.
What is logical to me is it everybody’s different and multivitamin is based on an average well they may be getting too much of one and not enough of another. I would think everybody should be analyzed for find out which vitamins are really needed in your body and then you just supplement to take care of those but multivitamins know I take them and when I tried to multivitamins, it caused me more problems. I stick with my vitamin C and zinc. B12, I can tell a difference when I take these every other day or so when I don’t, I feel like I need more energy I’ll take my vitamins and I get my energy back that’s my personal opinion personal opinion
Hmmm, this seems like a weird thing to look at. I've never heard anyone say they are taking a multivitamin to prevent cancer. That thought has never crossed my mind.
Soooo if this is not within his domain and he doesn't know how to interpret the studies let alone have the depth of knowledge to analyze the studies properly then I have to ask why is he wasting our time unless he's just answering general questions and at the end tells everyone that he doesn't know what he's doing. One could argue that he doesn't know what he's doing. You see these dietary supplements don't work, That's why my cardiologist prescribed omega-3 ethyl esters and based on what I've read, I'm happily taking 4 grms daily.
Doctor Berg, but smart.
Thanks, Fabian. :)
Vitamin K2 is showing to have a huge benefit for reducing severe CVD, which this meta analysis did not include. The statement that supplements (let alone vitamins) have no effect on heart disease is easily debunked.
Absolutely true
How would you debunk it?
@@Physionic i assume you can easily debunk it by providing the evidence for k2 supplementation showing to have a huge benefit on reducing severe CVD
That's a good way, MC. It's true that is a shortcoming of this analysis. I think it would be better to simply look at it in the context provided than to dismiss the whole analysis simply because they limited their scope to a few vitamins, however.
These super duper META studies of everything all at once are worthless.They need to be specific for specific purpose. So generally asking are supplements good for health is meaningless, but is vitamin C good for scurvy is meaningful. And I agree with the previous commenter that vitamin K and Niacin are both good for CVD prevention.@@Physionic
It's hard to take Johnny seriously when he has to say "like" quite so much.
Not really ur stretching it but he’s wrong either way
All viewers need to do is block him from showing up in YT recommendations - like I did long ago,
I don’t think any of us are 100% right about it seems as a lot of studies have conflict of interests . So I don’t think either side of the argument will ever be 100% . We will never truly know the industry and how much it is all snake oil or not as much as we like to think we do and will.
In curious as to your thoughts on his claim that a large percentage of supplements are found to be infected with harmful bacterias
You bring up a good point, all kind of factors involved with supplementation. Is it a reliable brand? Was the sup stored and administered correctly? Is the dosage not too low or high? etc.etc. Lots of extra factors to be considered and can effect a study or individual usage.
"Bacteria", not "Bacterias". "Bacteria" is the plural form. regards.

Great content, Nick! What are your thoughts on Andrew Saul, aka the vitamin guy? It was from him that i learned about niacin supplementation. He has been featured in some of the bigger documentaries,e.g. "Food Inc."
Do I hear a slightly ironical tone in your referring to The Famous UA-camr as "Johnny and the Researchers"? 😉
From looking at Johnny Harris I would dare say that he does not use supplements nor does he workout.
We do not need suplements unless perscribed by a real medical Dr. If you need to take something, one multivitamen/day
will do.
STOP wasting money on supplements. Unless, in jest, you are aiming to suplement yourself.
GREAT CHANNEL!
Would those be the same Medical Doctors who told us that taking a 'covid19' 'vaccine' would prevent infection and transmission of the horrendously lethal virus? Really? The doctors who wore and required masks even though they knew nothing about gas flow through and AROUND masks. Those doctors?
Oh maybe I'm a bit slow and your comment was ironic. In which case well played sir.
There are so many confounding variables with these large trash can Meta studies that render most useless. Multi vitamin? Which one, what formulation of which vitamins? Argh. Worthless
Johnny needs a career in politics or alphabet media.
He has all the moves.
I think I have malabsorption of nutrients, especially after I turned 60, so have to supplement.
When my gums start bleeding, I know I have to supplement with Vit C.
My Vit D was 3 instead of 50 - 75 so I take that - I have actively avoided the sun for the past 30 years due to skin cancer.
I'm under daily high stress so I take Vit B12 and Niacin.
I have fibromyalgia with its accompanying IBS, so I often eat wrongly when I'm not nauseas.
I used to be able to get all my nutrients from food, that was in the days when fruit smelled so delicious you couldnt walk past without buying it.
I was bursting with energy on food alone, smoothies with celery, brocolli, fruits, oats, nuts and seeds for brunch (not a breakfast person), a massive salad before supper after gym, then something like steamed veggies and a cheeze sauce, chickpea coconut curry or or a chickpea omelette or tofu scramble.
Then my partner defrauded me out of my business, and I had to rent out my house and live in my car. So diet was whatever I could get. I developed really poor eating habits, and could not afford any vitamins at that stage, that was a real cheap junk food time.
Someone sponsored me a multi vitamin and a probiotic (Efficient Microbes) which was massively helpful in making me feel better and get through those days.
My husband takes a multivitamin daily, although as far as I'm aware you should take them after a meal, and he takes them on an empty stomach so I'm not sure if it's doing anything for him or if he just has expensive pee🙄
I have to supplement due to surgery
Why do people take supplements if their levels are already good? Does this mean their levels used to be bad, but now they're good and they just want to make sure they stay good?
The latter, usually.
B-12 if you're vegan
Very appreciated.
I don’t trust Harris, I’ve seen him attempt to talk about history subjects.
Right. Actually they say everything us now so......
Linus Pauling is still correct...🎉😁🤩
Linus Pauling was a real scientist. He's been one of my very few favourite people since 6th form at school, when we used his book Chemistry.
We know, a lot of science was bought up by adequate orga- lines...🤪
The problem with multi-vitamins might be what they don't contain.
Vitamin D3, K2, and magnesium for example.
Multi-vitamins/minerals could be a basis of a supplement regime. But what about the rest, the things you really are deficient in?
I find it hard to belive that supplementing with those things a large percentage of the population is deficient in wouldn't make any difference.
Then sometimes supplements has forms of vitamins which are known not to he the best. So, they don't do much good.
But mosttly, I think the research being dome is not able to pick up on the effect when there is one. To include 84 insufficient research papers is very likely to produce a null result. It's a qustion og garbage in, garbage iut.
It's my belief that a good diet and only those supplements we know isn't covered by that (such as vitamin D) is pretty optimal. And that the multivitamins is just an unneccesary insurance. They do no harm, if well formulated.
How many of you have optimal levels of Boron, for example? Or iodine and selenium?
Yes, our salt might be ""fortified" with iodine, but not enough, and you probably don't eat enough of sea food, if yiu aren't japanese.
Fortification of food is a very bad idea, if you ask me. I would much prefer if each country just gave us a free supplemeent with thoe things.
Not everyone eat those fortified foods, you know!
Perhaps food labels instead should make us aware of that this food item has been processed to remove these natural vitamins!
That would make the producers fix things instead of glossing them over.
Forbid food "fortifications"!
Thanks for another great video. What about all the other diseases, Alzheimer's, dementia, diabetes, glaucoma, AMD, etc.?
A recent study shows that multivitamins are effective at preventing dementia
Johnny seems to be the kind of guy that googles a few things on the web and forms an opinion. Then he parrots the things he read without really scrutinizing it. This can make you sound smart at the pub or cocktail party. He makes well edited glossy videos that make it sound like he did deep research. However, when you dig into it, he's missed a lot of important nuance and can be misleading.
omG there is so much xxxx on the internet. One must really be cautious.
Never heard of the guy.
He has run out of topics to cover…he wants to be the next Vox, but that requires a solid research team…he should have stayed with geopolitics, his strong suit, because geopolitical opinions can’t really be evidence based…but I guess he wants to grow bigger (like all “successfully” UA-camr).
Jake Trans on his UA-cam channel did a better justice to the same topic, if you watch that.
Don’t know him. I’ll check it out.
Very good content creator. Kind of gets into the speculative but doesn't assert speculation as factual. @@Physionic
Not a competition. The more who cover topics like this from diff angles incl those w/Nic’s academic/ science background the better. Jake Trans doesn’t always get facts right (or cover all of them) and too often pushes what he’s supposedly calling out.
It's made me wonder: are we actually better off simply eating a healthy, nutritious diet instead of taking multivitamins?
No need to wonder, the answer is 100% yes.
@@Physionic Some nutrients are better taken in a supplement, though, rather than eating some unhealthy foods that contain it.
True. Good point. Probably not a huge issue for most, though.
@@carinaekstrom1 What, you don't want your daily dose of uric, phytic, and oxalic acids? Surely nature wouldn't have put those nutrients in plants if humans didn't need them?
Thank You, your conclusion in the video was not 100% clear to me.@@Physionic
Well, that was a waste of 12min of my life. Thought we'd eventually find a point in there
The best way to farm views is to call out popular UA-camrs. You don't even have to make a decent video, just mention a popular name, like Johnny Harris..
Or you just have something to say, which I did.
I'm sorry but while the basic analysis in this video is great as always, I'm pretty disappointed in the conclusion you draw at the end. The primary issue is this extrapolation that it makes supporting the whole video saying "well supplements basically don't do anything." That is his ultimate takeaway and interpretation of what the study communicates, and that is hopelessly wrong. Vitamins and supplements are not the same thing, and as you point out in the video, the result of this study is pretty expected within the paradigm that supplements absolutely can do very significant things. His conclusion that he tries to draw that supplements are basically meaningless is extremely anti-scientific and is the main problem with his video.
There's a lot of gullible people out here. A good BS'er can get a great following.
His gun control video from his trip to Switzerland is pretty terrible too. A total misunderstanding of what he was looking at compared to back here in the States. Several of his claims in that video are entirely untrue and based on his biased perception of how the average American owns and uses their firearm. ¯\_(ツ)_/¯
Fact checkers ? WTF
what a pretentious manipulative misleading title....
Someone needs to iron their shirt before giving us scientific information. 😮
(Johnny Harris)
Go away
=)
First(ish)!
all a con imo.... none made any difference to me
You’re already dead?
have never been fitter and feel great... i eat well tho ... love your videos @@Physionic
Jeez what waste of time this video was
