The DANGEROUS TRUTH about VITAMIN D - Dr. Westman Reacts 

I could swear that trials were done during the recent pandemic and there seemed to be an extremely strong correlation between vitamin D deficiency and a poor outcome 🤔Given that moving lock stock and barrel to a sunnier climate is not practical for most people, supplementing seems like a logical, cheap and efficient way to get the Vitamin D that is so vital for so many internal functions. I don't think I've ever met a doctor yet that hasn't advised supplementation, until now, for those of us that simply can't get enough sun exposure regularly.

I have followed Dr Westman's plan and videos for years and have usually found his advice right on. On this one I am afraid that I have to agree with the other side this time. I started using D3+K2 4 years ago. Since then my allergies, psoriasis and osteopenia have all had a considerable improvement.

Ive learned so much from Dr Ekberg. His way of breaking down complex subjects into concepts the lay person can understand is unmatched on RU-vid. Im with him on this one.

I love your videos, and I love Dr Eckbergs videos as well, he does tend to speak in generalities and avoids diving too deep in the science (similar to Dr Berg) but I have found that his style has such a straightforward, almost hypnotic way about it that makes it easy to follow for a lay person…he also avoids hyperbole and corporate sponsorship which also adds to his popularity, and is always a plus

I really enjoy your Reacts series. As many others have said, I watch Dr. Ekberg and think highly of him. And, I agree with him on testing Vit. D and making sure your levels aren't low. I also support retesting at different times of the year and if supplementation changes are made. That way you don't get too high. I think you need to exercise (walking) outside in the sun and without sunglasses and sunscreen on to have a good Vit. D level. A whole foods diet is great, but it's not the whole story. Outside time is important for Vit. D and circadian rhythm too. Maybe do just a bit more research on what Vit. D studies are really out there. Dr. Campbell did report on several studies during the C time. I'm sure sometimes you have appreciated anecdotal reports on keto...kindof the same with Vit. D. As a breast cancer survivor, I aim for a level of 70 (US).

No need to critique our dear Dr. E...He’s got our backs.

My husband and I went to a new doctor. She had a fit that we were taking 5000 units of d a day. She ran lab tests and found out that we had low normal levels, while taking 5,000 units a day! We also take vit k with it. My family eats healthy foods. Please keep in mind that current fresh produce only contains a fraction of the vitamins, minerals, amino acids and enzymes, that people in the early 20th century ate. There are studies regarding this.

The main message is that low serum vitamin d status is found in all kinds of chronic ailments. So, any RCT would have to run for 20 to 30 years taking several thousand people with low status and give a quarter vit D3, a quarter Vit D3 plus Vit K2 and a quarter Vit D3 plus Vit K2 and Magnesium, then see who gets what, or not, and who lives longest. There's no money in Vit/mineral supplements, so the only organisation (other than governments) who could run such a trial is Big Pharma, and they do not want to find any success in this arena as this might stop the need for their products. So, the best bet is to study a random range of 70 to 80 year olds by checking their serum Vit D levels, and check cancer, MI, and all cause mortality against the levels. If more of these is found with low levels, then we can move serum testing and supplementation into mainstream. This could yield some results within 5 years, rather than 10 to 20 years with an RCT.

There's no randomized control trials on parachutes either. Just the same, if I have to jump out of an airplane, I'll go ahead and rely on the strong correlation of success in using a parachute. Nobody is going to fund a randomized control study on a 9 dollar supplement

I live in Ohio and all my adult life doctors checked Vit D. The best way to get vit D is from the sun....which is why most Ohians are low. There's not enough sun exposure here for your body to make it's own.

Dr. Annette Bosworth, M.D. (Dr. Boz) has quite a number of videos including the research/studies showing the critical importance of vitamin D3. She not only is a key influencer and proponent of living a healthy ketogenic/fasting lifestyle .. she has incorporated it into her clinical practice. Dr. Boz is adamant on the critical importance of Vitamin D3. ✨

He is right...but we don't always need studies to prove things. I was low on D for tears and no food or lifestyle could up it. With it higher, I sure feel better now.

Sten Eckberg is the number one content maker that has turned my life around. He does a great job with keeping the content interesting by discussing how the body really works. His suggestions have proven themselves with me personally over and over again. Dr. Eckberg is a top notch creator and I have confidence of the value of his presentations.

Sorry, Dr. Westman...your other content is 🎯 but not on this one...I'm 100% with Ekberg on this! 🤦 I've been deficient growing up (my teeth suffered quite a bit😔)...now I take 10,000IUs with K2 every other day (on top of doing ketovore) and my vitD levels stay consistent at 90...never felt better! 😎✌️

I have followed a keto diet for 5 years and am very happy. I grew up with a vitamin D deficiency because of rickets . I have been very careful about getting enough vitamin D and I take 5,000 per day in the winter and skip a day in the summer. I honestly don’t know how to get enough D in the food as very little has it. I’ve had my blood levels checked numerous times and always fall within range. If, I’m lacking supplementation, I wake up feeling depressed. I eat 2 meals a day and again, I don’t know where I can possibly get through my diet. I have to disagree this time, doctor Westman.

I live in Eastern Canada where winters are long and sometimes quite harsh. I've been supplementing from fall to spring with D3 2500 IU's daily for years and will keep doing this. I don't see this dosage as being anywhere near toxic.

I'm sorry I have to be on Dr.Eckerg's side on this one. It's not easy to get Vitamin D when I am working indoors, in front of my work computer all day and I don't go outside in winter time because it is freezing cold in my area. I have to take supplements Vitamin D + K2. I'd like take natural foods like you said but Vitamin D is not available in a lot of foods. Even when I take 40,000 IU in a day, I don't feel anything worse but better. And I need VIt D like I need meats daily. Dr.Eckerg is a great person like you. I learned from him to treat my pre-diabetic symptoms and I felt so much better and happy in naturally way like eating keto foods + intermittent fasting.

Found out my vitamin D was borderline in 2020 it was at 30 so Dr said i might need to supplement. Started out at 2000 a day and took over 2 yrs to get it up to 50 so i've been taking 5000 to 15000 a day along with K2 MK-7 and sometimes magnesium too. Been on keto diet for over a year and my health has really improved at age 67. I was really bad diabetic and sinking health but have been off all meds for over a year. Dr told me to come back in 6 months unless i need to see him and he will recheck my vitamin D level in February when my appt. comes up. I think most of my health improvement comes from keto but vitamin D also seems to help my immune system.

Dr. Campbell, Professor of Nursing in the UK, has reported considerably on studies re: Vit D and COVID. The data was rather strong, but at the moment I don’t recall what type of studies. He’s usually quite cautious about looking at qualities re: the studies, always documenting what he shares. I’ll have to go back to see what he referenced.

I very rarely disagree with Dr. Westman but I will in this instance. I just do “Layman research” but I try to keep my sources credible and everything I am learning about immunity etc. agrees with Eckberg.

In the very early part of the pandemic there was a doctor in France who figured out how to predict the people that would end up on a ventilator. It correlated with high body fat percentage, high inflammation and low vitamin D. Dr Westman might be right that all we're seeing is correlation rather than causation but personally I am on board with vitamin D. I feel noticeably better in the summer when I'm getting sun.

There is a suggestion that vit D can just be a proxy for sun exposure and it is the Nitric Oxide which is the thing which delivers health effects. Similarly, sun exposure is also critical in delivering infra red to the mitochondria. I place a lot of value on what people like Dr Joel Gould has to say. I think Dr Ekberg is on firmer ground than you suggest. I am also thinking about the studies on nursing home subjects who resisted Covid, and those who survived infection from Covid.

Agree with Dr. Ekberg. The importance of vit D has been highlighted in the past years. For elderly people who are living indoors only (retirement communities) the consumption of vitamin D is a must.

Dr Ekburg does more research than just about anyone in our low carb/keto community, all doctors included❤

Understand where you are getting at Dr.Westman but this round I am with Dr.Ekberg on this as I have been on Keto for 5 years and taking D3 + K2 ever since the beginning of covid started and see the benefits.

Vitamin D blood level should be at least 50. When I got my level up to 50 I stopped contracting viruses.

It seems to me that Dr Westman likes to critique Dr's that does research on the latest trials and evidence instead of doing so himself. He waits for other medical establishments to declare that there are research and evidence (19.40). The problem with that is that most of them are influenced by Big Pharma and they won't push anything that won't make money. I prefer watching the Dr's that stay informed on the latest trials and evidence. Critiquing other Drs instead of doing your own research leaves a bad taste.......

Did shift work and worked nights so slept during the day. Went to the doctor because I kept getting sinus infections and just felt sick all the time. When my vitamin d was checked it was 12. Got prescribed vitamin D2 and a b12 shot but was told to take D3 over the counter. I literally felt better almost immediately after taking the D2 and D3 a few hours after leaving the docs office. I still find it hard to get my Vitamin D level up over 50, even with a proper diet.

My mother suffered seasonal affect disorder (SAD) during winter and needed large doses of Vit D. I took extra during covid (with other vits and herbs) and stayed healthy.

Dr Westman I’m with Dr Eckbert on this too! I feel so much better since my D levels have risen.

I have my Vit D levels checked annually. With just a multivitamin and no additional D supplementation, I am deficient, below the bottom of the "healthy" range ... I'm old - no time to wait for results of long-term clinical trials or double-blind studies...when I take an additional Vit D supplment, I at least get into the 'low but acceptable' range. Will taking Vit D-K2 supplements in reasonable amounts hurt me? No. Will not supplementing hurt me? Maybe. Net-net...I'll be continuing to take Vit D-K2 supplements.

I’m with Dr Ekberg on this one - even with an adequate diet, vitamin D is a must particularly for us who life in the northern hemisphere. Of course we must be vigilant not to overdose but that goes for lots of things😊.

Vitamin D3+K2 along with sunshine, even in winter has changed my life. I’ve done keto for years, adding this along with magnesium malate & giving up dairy is what finally made the last symptoms of my 25 year fibromyalgia go away. I don’t take it everyday in the summer, but I do in the winter.

Low D causes teeth grinding, and I never knew this until recently. I was very low even with daily walks on the carnivore diet. My teeth grinding is now gone after 10k IU a day for a few weeks.

I used to have constant sore throat and severe psoriasis but eversince I started using Vit D, my psoriasis improved a lot and very seldom that I get colds/flu or sorethroat. Dr Westman is so cute and I like him much but I have to disagree with him on this one.

NP here. I check most patients d oh level, discuss sun exposure, and prescribe d3 replacement. I find that if patients are in the 20s with their level 2000 iu early in the day with food will get their numbers the normal range. I have had about 25% of folks with levels around 10 and prescribe 50000 iu weekly for 8-12 weeks, and require a lab for a refill. Most people do not get sunlight exposure between 11-2 daily. Also have patients with CKD or obesity with low D levels. Have had one patient with hyperparathyroidism that developed d toxicity (nausea and vomiting). She was taking crazy high doses of d3 because she was worried about COVID 19 that I did not prescribe. I am shocked at Dr. Westman’s approach as he advocates for a ketogenic diet which has not been widely studied either. Furthermore, I find it concerning that dr. Westman doesn’t seem to understand that vitamin D3 disrupts, melatonin production, which promotes daytime wakefulness and seems to think that dietary vitamin d intake is adequate. 🤔

He has a PhD in Chiropractic & PhD in nutrition.

Vitamin D has helped my wife with her energy. She has stage 4 colon cancer was diagnosed last year and we found out she has a genetic disorder called MSH6 lynch syndrome. She is on immunotherapy and the cancer is shrinking. She told her doctor that she feels good but just a lack of energy. So the doctor said let's check you Vitamin D and it came back that she hardly had any Vitamin D so the did an infusion and have her on supplements. And she has much more energy.

You're right about not supplementing vitamin D if you have proper diet but Ekberg says to get vitamin D from the sun too. There are many countries in the northern latitudes that don't get much sun in winter so vitamin D is necessary. It's hard to get all of your vitamin D from just food.

I will take Dr Ekberg opinions over Dr. Westman any day.

I’m going to have to go with Dr Eckert on this topic.

Thank You Dr. Westman for a valuable discussion on an important topic. 😊 👍 IMO, one of the MOST CONVINCING concepts I have seen on this Vit-D topic is: everyone should have their Vit-D level BLOOD TESTED. IF - your level is low it would probably be Wise and Harmless to begin taking daily D-3 Supplements daily for a few months and then RETEST the blood level to actually LEARN HOW these SUPPLEMENTS are performing in your INDIVIDUAL body... Conclusion, Is "low" Vit-D Harmful...? PROBABLY. Will taking SUPPLEMENTAL Pills be a benefit...? Only periodic testing can answer that... -StayWellEveryone... -70SomethingGuy

Anyone north of the Mason Dixon line here in the US is vitamin D deficient because we just don't get enough sunlight. Many people south can be deficient due to the use of sunblock lotions. I don't think that you're going to get good randomized trials in the US. Have you tried looking for information outside of the US where BIG Pharm isn't in charge? I was surprised a few years ago watching on a channel of Poland on streaming where they actually were advertising vitamin D on their news station. It wasn't a particular brand either. You would NEVER see anything like that here in the US. BIG Pharma can't make money off of it. I just had mine tested recently and was low. I think it's so much more than just getting it through your food. I encourage you , Dr. Westman, to research more on this important vitamin( hormone), and maybe through research done in other countries that aren't the US.

I've had my vit D levels tested several times, and even after years on variations of low carb/keto/carnivore and taking up to 8,000 IU of vit D3 daily, along with K2, for years, my vit D levels are still barely in the middle of the normal range, around 45 ng/dL.

Sir, I suspect Dr Ekberg knows a lot of what you're saying in criticism, but explaining would go beyond the scope or time in his videos to hit on all those topics - he likely has other videos getting into some of that as many other online doctors do. I wouldn't assume he doesn't get some of the various variables at this point; he's clearly more up-to-speed on this stuff than most of doctors in the USA (in my opinion).

Did not Covid patients with low VD have worse outcomes? Since taking 10,000 units D3 for 6 years I've had no colds or flu, but I did catch Omicron

There are many other doctors who agree with Dr Ekberg

The problem with Vit D studies, has been the dose, same as so called 'low carb' studies. Don't hold your breath for RCTs. I appreciate your keeping us honest with the science, Dr. Westman! Check out Dr. Campbell on Vit D.

My rheumatologist has looked over his glasses a couple times while reviewing my blood work. "You haven't been taking your vitamin D have you?" I don't skip it anymore! Along with K2 and boron helped reverses the severe osteoporosis I was diagnosed with 20 years ago at age 70. Atkins at the time of my diagnosis but have progressed to way Ketovore over the last couple years but who knows if that was a factor.

You are stuck in the mud my friend! You, ironically remind me of how my primary care doctor treats me when I talk keto! She is a skeptic, and stuck in her traditional ideas. I think Vit D is too important to just dismiss... especially in the ear of Covid. Healthy bones are important as they found out in days gone by, even more important as we age, but anything you can do to boost the immune systems, seem like a no brainer. And you would recommend a multivitamin, if a patient was concerned? Most of those are flushers and do little to nothing!

Twenty years ago I discussed this with two of my co-workers. All three of us had been to our doctors. Only one was tested for vitamin d and prescribed. Other two of us suffered and found the relief from seasonal affected disorder on our own. It definitely does work. Check another vote for Dr. Ekberg.

The vitamin D experts suggest you want to up towards the top of the range. Not being near the equator I take a little vitamin D in winter as you will make much less vitamin D when the sun is low in the sky.

Studies of who died of covid v those who lived through the infection was predicated on their initial vitamin D level. Vitamin D levels are also a factor in fighting infections and cancer.

My dog and I walked our daily mile yesterday, plenty of sunshine but 35 F so I was covered head to toe with clothes and kept my hands in my pockets, also wearing sunglasses. Not much natural sunlight made Vitamin D even though we were out in the sun for 45 minutes. So, I take 5K Vitamin D3+K2 1/2 the year and double it to 10K IU starting in the fall. My blood work last Sept. Vitamin D was about in the middle of normal range. BTW never got jabbed and never got "the bug". Let food be thy medicine and let medicine be thy food.

Ekberg is a very informed man. My doctor just prescribed me vitamin D3 after my blood work showed I was lower than normal. I've been eating keto for about 1 half year now. I've lost 40 pounds and have kept it off. You should listen more to doctor Eckert and doctor Berg, they are both very informative people.

Stan Ekberg is amazing with his advocacy of low carb/keto nutrition. His knowledge is vast and researched . Dr. Westman you are way behind the curve on this subject and your awareness of Ekberg's video teachings. For all you do, you need to explore more in depth nutrition as Ekberg has.

i appreciate your channel very much - but also that of dr. ekberg. of course you are absolutely right with your references to other factors, but if you know that vitamin D is hardly present in food and a walk in the sun is completely insufficient, i don't understand why you shouldn't supplement it in moderation.... (by the way, always together with K2 for good reasons). best regards

We take vitamin D in northern areas in the winter because, with all the layers of clothing to keep warm, we are not exposed to the sun very much in winter. Our grandparents took cod liver oil all winter. Thank goodness I missed that generation. I continue to take vitamin D in winter. My doctor noticed an increased level of D in my lab work and told me to cut back the amount. We heard a lot of talk about Covid and the increased morbidity in the Chinese population versus American. It was suggested that decreased levels of D compared to Americans played a major role in the severity of the disease. I don't get colds and flu, though I did get a mild case of Covid for two miserable days. At 78 years of age and an overweight diabetic, Covid was supposed to be dangerous. I attribute my resistance to colds and flu to a basically healthy diet and regular intake of vitamin D.

Naturopathic Medicine is my 1st choice to help reverse disease. Western Medicine 2nd choice in the Emergency Room, but has scary side effects.

I worked night shift 30 years and my vitamin D level was 0 so I was ordered a supplement

I have no idea what is right and what is wrong, but I do know that most doctors (at least in U.S.) take a vitamin D level and put you on vitamin D if you are low. So it is not so odd. Again, I don’t know if it right or wrong, but everyone I know that gets blood work, vitamin D is checked. I don’t take supplements, sometimes electrolytes, but I do enjoy Dr. Ekberg’s videos in general.

I'll say this much, a good friend in excellent shape, eating healthy and very active, got put in bed by a bad cold for 2 weeks, when I noticed he gave it to me, I took 5 days 50.000 IU Vitamin D3 + K2 and was absolutely fine after 5 days, even though I'm generally in much worse shape than him.

Thank you for confronting the analysis/approach of two BRILLIANT different type of doctors. It adds value.

Dr Westman, how is it you have never recommend for patients to take vitamin D3/ K2 to you patents? Do you do blood work to see if vitamin d3 level? I am very surprised and dishearted.

Paul Mason has a theory that vitamin D is mostly a downstream indicator of proper cholesterol levels which he believes is the main thing promoting health and the reason vitamin D increases with sun exposure is it acts as a natural skin protection or screen. Interestingly those who do keto and carnivore usually find they can withstand much more sun exposure. I know I can despite being very light skinned. It's an interesting theory worth listening to his lecture on.

I live in an area where no natural vitamin D is available from the sun during winter months. I do spend about 2 months of the winter in a warm state, but you better believe I’m taking a D3K2 supplement daily. Especially with all the crap they’ve released on us lately.

Great series, Dr Westman! Hearing a variety of opinions and the research each is based on is important to developing a balanced view of current nutritional information.

The problem is, you're never going to get that prospective study because no one will fund it, as you can't patent vitamin D. We only get large scale intervention studies, when there is a drug to be sold at the end of it. So while maybe a doctor shouldn't prescribe it, as an individual given it doesn't appear to be especially dangerous when approached conservatively, we may want to try it and see if things improve, or not, for us specifically.

Of course, the pharmaceutical company has told you to say that

Thank you for discussing this!

I take d and will continue too

Vitamin D3-K2 in flu season and winter. Lots of sun in the summer

If you don’t check your vitamin D levels you don’t know. I agree with Doctor Ekberg - as well as other Doctors I respect. My GP found mine to be very low years ago. But Doctors have different opinions- that’s ok too. (Good to be responsible for your own health and not rely on just your Doctor …)

I agree with Dr Sten Eckberg. Not many people can follow a nutritious diet all the time and not many people can spend enough time under the sunlight; I believe vitaminD3 supplement is necessary.

Dr Ekberg literally has his own "Wellness store" selling Vitamin D, K, etc 😂😅

left unsaid about the various influencers and chiropractors that hype Vitamin D (and other supplements) is that they also [what a coincidence] sell them at their clinics and their online shops. Ekberg, as much I like him and love his approach and presentation, does this too.

It would take over 200,000 IUs to begin to see toxicity from too much vitamin D.

If you’re very low on vitamin D, compared to other people which shall never be called normal, all the sun in the world all day long Would not be enough to correct the “deficiency “

Surprised at you taking a bit of a swipe at Sten Ekberg regarding lack of scientific data etc. Surely you and he have some things in common, also regarding what “mainstream” science still has to say about the Ketogenic diet method? They’re still not fully supportive, are they? So couldn’t the same be said regarding the “mainstream” scientific and medical community’s attitude around Vitamin B12? Maybe Sten is wrong and unscientific, but some would (stubbornly) persist in saying the same about the Keto diet.

Your adviced lifestyle and diet provides more vitamine D3 and minerals that help this pro-hormone and causes less inflammation in cells where vitamine D has to help the immunesystem. You probably agree more with dr Ekberg then you want to admit. I suggest a olympic declathlon between you two 💪😂

Finland has vitamin D studies. Fortifies milk with vitamin D. Maybe worth looking into.

Older people do not absorb vitamins as well, they say, so I add some. Dr John Campbells videos which began centered around the pandemic, cited many studies showing higher Vitamin D levels provided better immunity, and better lung function. I was in an industry where I got almost no sunlight, and I had breathing issues, running out of air climbing stairs. I got started taking Vitamin D3, and I could feel my lungs clearing out and not panting for breath. I think Vitamins should not be overlooked. To me, its $30 worth of health insurance every month. Dr Eric Berg has an electrolyte, that combined with triple type magnesium, has helped me keep up my power working throughout the day. I am in my 70s.

Prospective studies were done for Covid and vitamin D3. Major difference in health outcomes.

I like both these doctors and feel they are genuinely are there for the patients. I also believe in let food be your medicine.

I appreciate your perspective however, I’m with Dr. Ekberg, from my own experience and research. Vitamin D is tremendously antiinflammatory because it is a partial agonist of TRPV1 and blocks complete agonists of TRPV1 that can help stop central nervous system seizures and hippocampal neuron damage, also D genetically causes production of proteins critical for the balance of many aspects of our health. This is seen as it helps combat excessive bone breakdown by interfering with the RANKL reaction, helps decrease Schwann cell lesions in multiple sclerosis shown in a phase 3 study of ms patients, on and on. Unless a person has a genetic mutation that compromises metabolism of vitamin D then it is safe to take high doses of D. I have an autoimmune disease and am at my best taking 10,000 i.u. 3 to 4 times/day, for years. My highest D level was 350, my blood calcium was normal and no excess urinary calcium in 24 hour urine test, no calcification of soft tissues, I do also take K2 Mk-7 shown to prevent arterial calcification and I have been doing great! Epileptic patients refractile to medication were shown in studies to have reduced seizures by 25% just taking 10,000 i.u./day. Big pharma will not pay for the studies you want because they cannot profit from the information. Giving a bolus of 50,000-60,000 i.u. does not work as we saw in covid, it must be through the day, day after day as D helps T-cell function esp important for older people with waning T-cell function, the first layer of immune protection after innate immunity that covid easily surpasses. Obese patients are more likely to be deficient in D because active D is quickly converted to inactive storage D in adipose tissue. To be honest you should be extra concerned about that for your patients. PCOS patients have typically obesity and metabolic syndrome . Glucose stimulates TRPV1 that stimulates glp-1 that stimulates TRPV1 (again) that causes insulin secretion -> hypersulinemia-> more TRPV1 and insulin like growth factor 1 and both -> polycystic ovaries. When TRPV1 is too high it causes the disassembly of tubulin in microtubules in primary cilium on cell membranes that inactivated polycystin 2(TRPP1) needed to protect cells/tissues from out pouching-> cysts. So controlling TRPV1 with D is most helpful unless a drug or other agonist overrides D. Vitamin A is important to take with D because both use the same RXR receptor on the nuclear membrane.

Ultimate respect for you Eric, but I have seen a lot of evidence from other Keto proponents, and other MDS , and PhDs, that have demonstrated an undeniable correlation between serum Vitamin D levels, and general health. Especially when it comes to the immune system.

Like a small dog barking at a tree with a leopard in it..ie the wrong tree mr Westman

Take it anyway, won’t hurt

I'll give this video a like but I am with the rest of the comment section. With respect.

I love your videos but I guess being a doctor biases you towards pharmaceutical solutions. The problem with relying solely upon prospective studies is they primarily get done for lucrative products. If some drug company developed a drug that helped supplement vitamin D, you’d be all over it. Over prescribing it like everything else. I get you have ethical standards and limitations based on medical practice but hopefully isn’t holding you back from helping your patients.

I totally see what Dr Westman is saying, however, taking vitamin D3 for nearly 20 years has helped me feel so much better. And since I basically hate being in the sun very much I likely need it. And it greatly reduced colds and flu for my whole family.

eat a lot of fatty red meat and pastured eggs. get out in the sun as often as you can, without burning. Rinse repeat!

As here, haven't verified, but the report was NO TOXICITY after 40kIU/day over a year. I'll keep taking my 10k. I never supplemented, relying on average 4hr day sun 90%+ exposure. I don't get ANYWHERE near the time since starting supplement.

I saw Dr.Ekber's videos first and they are what led me to Keto/Carnivore.

You don't think you should test for Vit-D? Probably good since most D (according to the science videos I have seen) say it's not in the blood, but mostly in the cells. It may help to test the blood for some indication, so I'll defer, but not because Medical Schools didn't recommend it or teach about it to you. The Medical Schools and governments are obviously some 50 years out-of-date on a lot of nutritional health topics, and, so, many doctors would rather treat symptoms rather than try healing the CAUSE; e.g., the out-of-date Food Pyramid, My Plate, and what not. Even my Doc-In-Box (he's 50 something) was clueless about what is good about the HOMA-IR and C-Peptide tests for people with metabolic syndrome or prediabetic, there is no excuse for than in my view.

I don't know... but my medical doctor recommends at least 20,000 IU vitamin D3 supplementation daily. He says it almost impossible to OD. I have taken a lot more than that for decades with no adverse effects. I live in Pacific NW USA where the sun doesn't shine often.

Very informative

Dr Ekberg is absolutely fantastic. I haven't checked your other videos, but his knowledge of biochemistry is absolutely top notch. This vitamin D video is a little bit off his normal topic. But he is so learned that I honestly trust him innately, though do know I cross check all information woth other doctors, research and professionals. That's how I found your channel, in fact. Also, once you understand Dr Ekberg's style, you will probably give him some time to cook before going deep into reaction mode. He definitely clothes most of his videos, which are deeply educational, in clothes that initially appear to he some simple list. Bring 'em in with a meme or promised list, then educate them before they know what's happening. Seeing how you cut the video off before it ended, I promise you that you dodnt get his whole picture. It's a bummer too, because thats probably what a lot if people do. One last thing. Please don't dismiss this man. I figure all people, including or especially medical doctors, can learn something from him. I am not saying to simply accept everything he says at his word, but he reads and learns medical texts simply for fun and of the 500-700 hours of books, RU-vid info, research reading and other learning about low carb and fasting, Dr Elberg stands out as one of the best. Ekberg is pure distillation of information. Pair him with Dr Robert Lustig, who also has incredible knowledge and expertise but has a more... passionate... presentation and you will have yim and yang. But you know how the cardinal sin of music reactors is stopping during a guitar solo? Cardinal sin of Elberg videos is stopping before he is done. Edit: OK, rewatched the whole video and it looks like you finished it and I misunderstood that you edited it. I apologize amd will leave my original text for those who already read my answer. I believe in accuracy and being open when I err.

Yes, thanks, appreciate it.
