My wife had crippling sciatica pain last year for months. Endless blood tests. xrays they prescribed pain meds but did talk of adding in thyroid meds. As a retired engineer, I was concerned the effects on her liver. We got hold of her blood tests and using pubmed as my guide, worked out she just needed minor diet changes (primarily more fat, less sugar) and added modest doses of Vitamin D3, K2, some turmeric, magnesium each day. These are all commonly deficient as we age. In our case all pain was gone in 3 weeks. A pity they don't teach this basic stuff at med school.

Best produce in the world? Dandelion, Plantain, Mellow, Milk Thistle? Fresh in my garden, picked, chopped, popped in my food and consumed within minutes of picking..

It’s been 5 years since this talk. It would be really good to get an update, and Dr. Tice’s view of supplements today.

I don't understand the criticisms. We all know vitamin D should be taken with calcium and K2 but the point he is making that taking synethic vitamins in isolation (which is how most people take them) is either not effective or causes harm. Eat whole natural foods so there are cofactors for proper vitamin absorption where possible and supplement only for deficiency.

time is a big element in our busy lives. A lot of us don't have the time or money to spend on whole foods. That's why we do supplementation where we can get a high concentration of nutrients as we can get in a multiple vitamin

I feel its impossible to get all the supplments and minerals, etc, from just your diet cause you will have to eat all day and have a very well balance diet to get all you need. My mother took alot of different vitamins and lived a good healthy life till 92 yrs old. I followed her foot steps and I will be 70 yrs old and by fair do not look my age, and am not on any medication.

to sum up antioxidant section: more is not necessarily better. to sum up vitamin d section: stop wearing sunblock and go walk (don't drive) naked in the winter time.

This guy's info on Omega-3 benefits seriously needs updating.

The negative effects of concentrated/ isolated antioxidants have been known since I was in university 20+ yrs ago. Dr Colin Campbell’s book ‘Whole’ gives an extensively researched and experienced compelling argument against the reductionist strategy for nutrition.

Before watching video > Read all the comments below. WOW

When I take fish oil my triglycerides drop. I go for annual blood work and my Doc noticed I was not taking the fish oil.

nah, just not good information, very out of date. if u watched.. always take D3 with K2 and never take Calcium without K2 (in fact Calcium is not a good thing to take unless u have to)

Also, adding a little grass-fed beef or pasture-raised pork, chicken, and eggs won't hurt and will help the planet as these products come from farms that practice regenerative agriculture.

What a wonderful lecture it is~ We are very lucky to watch that video. Thank you.

weigh the risks?! Pretty much, none! Let's talk about drug risks...

Before taking anything there needs to be a few hundred year double blind study we can all then tear apart once it’s released.

D3 ptovides twice as much 25-hydroxy vit D in the blood than outdated, cheap D2. I am always amazed at doctors preference to give megadose D2 weekly or monthly while a smaller, daily dose of D3 gets better absorbed.

22:35 this is crazy information that I find hard to believe👆 I'm taking 6000-8000 mg vitamin c per day and I can now recover a lot faster from weight lifting workout while also feeling more energized. I don't supplement on A, beta-carotene or e but I eat a lot of carrots, orange, turmeric celery, broccoli, onions, ginger, garlic and so on, and by the way, he fails to point out that carrot consumption together with tobacco smoking, that's the real dangers of lung cancer and increased mortality from beta-carotene 👆

Wow! This guy is Mr. pharmaceutical company number one. If you want to learn something of value I suggest seeing anything on KZfaq by Dr. Levy or Dr. Lustig. You will be glad you did. They are both eminently qualified and of great value in their presentations. John L

Thanks! 🙂

I was prescribed Premarin after my hysterectomy, I had an allergic reaction., my whole body had rashes, very itchy, immediately was stopped.

Prediction: studies will continue to come out saying supplements are either beneficial or detrimental to our health. It's impossible to definitively prove either way because it's impossible to completely control for the many other factors related to our health. Meanwhile, the researchers need something to do.

I wonder if people taking vitamin supplements don't think they need to eat as carefully, so their diet counteracts any benefits?

You must tell us where are your researches published in which journals. Who did those researches. Pharmacetical companies might like you. What is your CV (any epidemiology or medical statistics).

so where to find the results on Vitamin D that were to be reported in 2017 ?

I guess if more is less, then none is perfection.

It is good hearing health lessons of the findings of the touted nutrients of long ago. I have added slowly enough to my aging organs the clinical successful nutrients. It's easy to dose too much. So hard to trace amounts. I use quantum succinct and titrate up to my dose up.

I'm only into this 11 minutes so far, but I have to make a comment. The speaker says we shouldn't take a supplement if we are already healthy. Well, I've read that the majority of Americans are unhealthy metabolically, so I would think most Americans need supplements of some kind. Let's be honest, how many doctors will spend the time analyzing your labs to see any trends? They will only prescribe something if something is WAY out of whack, not just a little.

I drink dandelion tea. Taking 5 day break from Milk Thistle. I also take whole food Vitamin C, D3+ K2, the good magnesium.

Clear presentation of data study. Medicine really is a form a statistics these days. Two comments: there is the clear principle that is ignored in our culture, especially in politics: correlation is not causation. Here, correclation is called "observational study" Same thing. Correlation provides a hypothesis not a conclusion. Second: D3, it turns out is clearly related to the power of the COVID reaction. Dr. Tice shows a map where we do not get sufficient D3 in winter; hypothesis: infrections are higher in winter, so take D3 supplement.

Vitamins and minerals taken in the correct way with improvement in diet an make one not worry of any discease.

Glutathione and vit a, c, e as well as vit d3 and k2, magnesium citrate is also known for deficiencies along with vitamin D.

Thank you so much for a long complicated video. I ask one simple question how much it cost of vitamin D and vitamin C in comparison with Pharmaceutical prescribed drugs? You ask for double blind research? Who is going to pay for these researches which proved vitamin work well, all of doctors, hospital employee will out of job! Pharmaceuticals only pay for study to prove vitamin don’t work. I am scientist, I know there are so many wrong design, or wrong translate statistic info to get what benefit for the sponsors. Since I took vitamin from 2011, all of my doctors, dentist out of job from me. I’m sorry but my health is more important!

Prescription medication, less is more.🤔

Look, if you can recycle healthy avian feathers and natural kelp/bones as fertilizer in your own private garden, then yes eating a moderately small amount of fruits and veg grown from it is reasonable. The world's soil is simply not as nutrient rich.

I hope nobody else has to watch this guy for their general education class. I want to start doing indescribable things out of anger.

Comments better than talk.

Thanks , Very informative, great presentation.

I Suggest everyone google “Number of deaths annually from correctly taken Pharmaceutical drugs. “ Then google “ Number of deaths annually from Vitamins” You will understand quickly. John L

I'm sure this doctor means well, but there is so much wrong with this presentation... For example, the section about calcium and vitamin D is mostly worthless. I'll address only that section, as follows: For healthy bones and healthy arteries and heart you cannot study just calcium alone, or D alone, or even just Ca and D together. The body uses MANY NUTRIENTS SYNERGISTICALLY!! The doctor mentioned there are indications that high calcium can lead to heart attack or stroke -- that is correct. Ditto if one gets extremely high doses of vit D alone. D is needed to absorb calcium into the blood -- BUT THEN VITAMIN K2 IS NEEDED TO GET THE CALCIUM INTO THE BONE WHERE IT BELONGS. If not enough K2, some of the calcium gets laid down in the arteries leading to atherosclerosis. Another factor in this: If there is insufficient Vit A, any excess calcium again tends to get laid down in the arteries (and other soft tissues). Vit A escorts excess calcium out of the body. Also vitamin C plays a role in proper bone maintenance -- for strong bones you need to make collagen (for connective tissue) and you cannot make collagen without vitamin C. So for healthy bones, arteries, and heart you need vitamins D3, K2, E, A, and C, (and more) all as a symphony. Why do medical people do trials focusing on one or two nutrients only at a time? Could it be due to conflict of interests? Could it be that if people are cured via nutrition they will need less drugs and medical interventions? Study what NUTRITIONISTS say about nutrition, not what the medical profession says about that subject. (Unfortunately even among nutritionists you'll find controversy... critical thinking required in all cases.)

The lipid hypothesis is just that…a hypothesis and has not been proven by a double blind study. Why then do most doctors as well as the AHA promote a low fat diet?

Good to know most nutrients come from food (where we should get it from) rather than the shortcut mentality that most people have. At worse, most people believe that if a little is good, a lot must be better. I use to think that way before I met my husband. He was a lecturer and veterinary surgeon. He doesn't put his animals on supplements unless they are deficient. They get their nutrition entirely from food. He himself is one of the fittest men I've ever met. He suggested I try stopping all the supplements I was taking and get my nutrition completely from food. I was against that idea but thought it should be okay to try for 2 to 3 months. The transformation was amazing. My skin became clear and supple (none of the natural supplements I took even came close to what a healthy diet has done for my skin). Inflammation went down. Blood test results came back even better than the results I had in 2011 when I was on lots of vitamins and minerals (yes even food based multivitamins). I use to take fiber supplements too, but don't need that anymore because I get so much fiber from food. It was challenging at first because cooking fresh food takes a lot of time, but now it has become a lifestyle habit - I MAKE time. Think of it as an investment in yourself. The sad part is, before relying entirely on food, I was already eating relatively healthy but still had heavy reliance on supplements and not gaining any positive effects from them.

Nope. Quality is the key . Cheap Walmart vitamins are different than the better precursors

When no correlation with Smoking or Vit D or Sunshine is given, the study is void to me. There must be more comprehensive studies to track 10 variables or more with Design of Experiments (DoE) Taguchi Methods applied to statistics. Do Nurses Smoke more in old studies?

Can anyone explain to me why I get cystic acne that last more than 3 months when I take vitamin c??😨

I wonder if /which supplements,if any, are being made/processed in china ?

The Caret study on beta carotene is from 1996. Are you kidding me, 24 years ago (20 from this speech)? Also, there were many doctors who stated the studies were extremely flawed, such as using synthetic forms instead of natural, also using toxic food coloring dyes inside the supplements, also relying on questionnaires asking people what they were eating in addition to the supplements in the past 8 years, etc...

vitamin d3/k2 with coconut oil is prob the most important supp

One of the Doctors studies Alzheimer’s for the past 20 years in Oxford have found that Vit B12 plus omega 3 reversed Alzheimer’s doing placebo testing in others no effect said it Alzheimer’s can start brain disjunction in the young maybe not noticed but because of poor diet ect it starts then So my husband and I take these vits now as he was getting very forgetful and slow I can see a difference now I have always been interested in vitamins vit D and k3 during this pandemic keeps us going particularly for people living were very little sun in the winter

When I was 16 many decades back we didn't have vitamins and supplements figured out. We don't still. When will we?

How misleading! The title alone goes directly against the very foundation’s of orthomolecular medicine!

Listen and listen to these , I think they can be useful , but the most important thing is mental healthy.. I was nursing 31 years . So many very healthy thin people die the most slow agonizing deaths , the body was so efficient that if faught disease to the hilt. Then less rigid health people go quickly .enjoying life to the last minute. I think quantity is not quality. The key is each person needs to live the life that gives them quality . And balance , spiritual growth is most important. I am really not convince we control it that much. Ecclesiastes , there is a time to be born and a time to die. I tend to think our exit time may be guided by a power greater than our own.

I do 50 mg of zinc daily. I know it's high dosage but I'm also on hormonal therapy. I'm 69 years old and my gray hair is turning black. I've increased my copper to compensate for the increased zinc. and I do supplementation. you say don't take supplements. I'm on an island where I'm limited to all the great foods you are exposed to. what foods do you suggest?

If very gigh quality and organic if possible then its good, after seeing the GP i was offered vitamins but they were pharmaceutical products and not easily digested if at all, for example vitamin D, thiamin again crap quality supposed to be taken with a source of vitamin c or there is no absorption thus eventually becoming deficient!

I'm still a fan of Linus Pauling. This guy doesn't convince me. I do my own randomized trials. Thanks

University Of the pharmacy backed State of California.

Videos need a freaking TLDR and table of contents. AIn't nobody got time for dis.

For 50 years now, we are getting fatter and sicker, and the Doctors are still in denial. The AG, dept tells us what to eat, they may be good at growing it, but that has not translated into good for us. The number of confounding issues in these clinical trials are huge. Every one on the internet has an opinion, and that is all it is. Maybe people should just be quiet.

I couldn’t listen due to the uumm and aahhh consistently also the repetition of the the and that that. I’m certain he has a great deal of good information to impart.

Sooo...inconclusion.... we have a deficiency in pharmaceuticals!

Why am i watching this?? I revived from severe caugh that no doctor could cure and vit c did till today. Fckn wasted my 25 mins

Are you people sure that this guy is a real doctor ?

Must be food sourced. Hello.

Nice

Very disappointing. The level of understanding is rudimentary at best. This would be why a growing number of us stay away from mainstream medicine.

I can't get through the "ummm, ummmm, ahhh" pauses.

No, meta analyses don’t normally include observational studies as they don’t stand up to the rigorous inclusions set in advance

Thanks so much for this video its so helpful.

Good talk, as supplements should be considered by strength and quality of evidence just as with prescription medication and diets. However, part of this talk demonstrates how pervasive the misunderstandings of p-values continue to be. Even this physician researcher misinterprets p-values. Beginning at 19:10, he states this p-value indicates "the probability of this happening due to chance..." P-values do not and cannot confer this. They are probability of the data given the null hypothesis being true. In other words, they rely on the null hypothesis. Also, the "probability of this data given my hypothesis" (p-value) is much different than the "probability of my hypothesis given this data." Also, p-values tell you nothing about effect size. Basically, it's discouraging that the overuse, misuse and misunderstandings of p-values exist even at a place of scientific excellence like UCSF.

What about K2???????????

I take around 10000 mg A-day of vitamin C when I'm sick goes up to like 40000 mg. This is So importantt but I've been listening to this guy for 10 minutes and I haven't heard anything about it

Vitamin tablets is a waste of money ?? Well don’t think so !! Been on them most of my life , now 84 , in the workforce till 81 . and still the only tablets I take .

😂 I’m glad I’m not the only one that is confused by this video. Vitamins literally give me energy that I don’t have and I’ve used them to cure myself.

Highly highly overdependent on so-called statistical trials. Not to say that legitimate trials are useless, how did humanity exist before the random controlled study???

🦜 *I wonder: did you consider that young, healthy people don't take supplements but when they get sick they start to take it!?!? Konklusions from statistics are a bit complicated...* 🦊

Dr's listen more to drug salesmen who visit them regularly their offices than they do the vitamin industry sales persons who don't visit doctors' offices at all.

paid by AMA and Pharmaceutical companies

That's all I ever hear is eat a healthy diet etc.??? what about those who NEVER HAVE & NEVER WILL!?! like me!. like probably most people who look towards supplements to maybe help??? Do they help those people who are most likely Deficient???...

There is a very big problem here: the body is so sophisticated that everything relies on a lot of different factors working together in the right balance. You give Ca++ but the body can't do something with it: other electrolytes are needed to work with at the right moment with the right ratio (he does not mention the ratios P/Ca++ and K+/Na++) insuline level (active at the bones) and insuline resistence (very common), other hormones, movements and strength exerted on the bones (use it or lose it) etc. I read once that low sodium intake can lead the body to destroy bone tissue to get the missing Na++. I was shocked!!

Thanks doctor

Let's be honest vitamin supplements will never replace eating a well balanced diet.

My late fiance was an internist. He said that they taught nothing about nutrition and vitamins/supplements in medical school. He did his own research. I was smoking at the time. He believed in antioxidants and vitamins. He told me to take at least 500 mg every day because I had bruising. I took the vitamin C and I stopped bruising. This guy doesn't know what he's talking about.

OK, so, I like most of his presentation, however, I don't agree with his assessment that there is minimal benefit of eating organic foods. There certainly has been an increase of cancers in the population since all these chemicals have been introduced. The incidence of cancer years ago when people grew their own food was clearly significantly lower. Just an observation.

He never heard about methylation? Some people cannot convert folate pill into active form.

I did

Vit D and covid-19!

Humans, like animals, know instinctively what foods to eat. Or they did in their natural state in harmony with the planet. That is the problem with our materialistic evolution. We have lost so much in instinctual and spiritual ways of living.

Sounds like he isGuessing

Folic acid as a form of b9 is not good for people with MTHFR or slow COMT epigenetics....apparently about 30% of the population. Look at FB groups to explain more. B9 is needed with b12 but in a different form to folic acid. If slow COMT i take hydroxy subliminal b12 ....still working out b9

Masterkeywith Holistic Chef Barry Anderson Absolutely OLD SCHOOL OUT OF DATE ADVICE AND RESEARCH. MORE ON THIS LATER 5 months ago Nah, just not good information, very out of date. if u watched.. always take D3 with K2 and never take Calcium without K2 (in fact Calcium is not a good thing to take unless u have to)

mr master key stop sticking your key where it dont fit where is your curdentals

What does ummm mean?

Very informative

coincidentally was doing exactly this as i was listening 55:00 I thought I was a weirdo for having a skinny latte and a sardine sandwich just while watching this, need full fat in future though

"It doesnt mean Linus pauling was right." LOL ILL CONTINUE TAKING HIGH QUALITY MULTIVITAMINS WITH HIGH DOSE VIT. C.

Whenever a medical expert, whether it's this guy or any other mentions the word study, they need to start off with who FUNDED THE STUDY. I grew up, thinking that scientists where all looking for the truth. That belief has been shattered in so many ways, so many times since then.

A proper diet is all that is needed. Many ladies I know sail right thru menopause without any discomfort at all.

Doctors talking about nutrition… 😂. The last person you should trust concerning staying healthy.

Now they are in gummy's with sugar like taking a sugar pill
