In the winter in more northern latitudes, most people will be deficient in vitamin D. There is just not enough sunlight. In addition, if you have a darker skin, you will probably have a deficiency. I am in the UK. My doctor, who is Asian, told me that he and all his family take vitamin D supplements. You should take K2 with vitamin D because D increases calcium in the blood. K2 helps direct the calcium to the bones so it is not deposited in the arteries.

I hate to say it you are a wonderful person in the doctor, medical school teaches people wrong. I’m sorry..😮 I did my own research on myself. I read all kinds of papers. I have melanoma stage four and I got over it. They said stay away and stay away from the sun. I felt awful. I was taking 1000 IU vitamin D3 , my sinus were terrible every day I had a sons pill I couldn’t get in the sun again I would burn up, I started taking 5000 IU vitamin D3 and K2, twice a day that’s 10,000 IU , after several weeks, my sinuses were clear I was sitting in the sun in the winter time for a half hour a day I got golden Brown. I never felt better. This is been four years now and the studies I come across., you can take 50,000 Iu a day and nothing will happen, and statins no way in shape or form take a statin , it kills all the cholesterol, and you did some research about cholesterol. We need cholesterol so badly and nobody died. Nobody died of too much cholesterol., it’s the drug companies pushing their product. I’m sorry but I’m a living proof. I’m 64 and I’m so much better now.

What you're saying is called an anecdote. One Anecdote can say one thing, and another anecdote can say the complete opposite. That's why they're not reliable. And that's why we developed blinded controlled studies where no one knows who's getting the pill with the real Vit D in it until after the study ends. We learn a great deal more from actual studies which can contain thousands of individuals and the data on how things worked for them. It's good, strong, reliable data. And I'm sure that's why the physician is reporting the results of several studies. By the way, my dad was diagnosed with stage 4 melanoma. He drank everyday and ate hot dogs and pizza every day. He didn't take vitamin supplements nor take care of himself and he lived for 21 more years. He was riddled with cancer. My mother exercised every day, researched and took vitamins every day and she died from having too high cholesterol. She had to undergo 2 bypass surgeries due to her arteries getting so clogged up. So yes, people do die of too high cholesterol. Both my parents' experiences are just anecdotes. It's the combined power of the studies that tells us overall what works best, not anecdotes.

I only became eligible for vitamin d testing after I was diagnosed with osteopenia, and learned I was deficient. At that time I had only been getting about 400IU of vitamin D from cod liver oil, plus a little more from fortified yogurt and fish-little direct sun because I had also had skin cancer. But the amount of supplemental vitamin D required to get my level up to 40ng/100nmol was 4400IU per day for 3 years! Since then I have dropped back to 3000IU/day, but I have halted my bone loss, reduced the number of respiratory infections, and improved my mood. If I had never been tested, and had only started taking 800IU/day, I think I would be in much worse shape, if I would even still be alive.

I have been following Vitamin D research for over 15 years. This person is either suffering from her Big Pharma indoctrination and bias that she received in Med school almost 20 Years ago, or is a malicious shill for Big Pharma and Big Med. We all know that all of the agencies and Med Schools are completely captured by the Medical Industrial Complex and thus any anti D studies must be held to a high degree of skepticism, especially if there's ANY conflict of interest. While lightly touching on the importance of D in the body aside from bones and teeth she promptly ignored this most important aspect of D and Health. Her 'levels' advice is completely flawed in my opinion. For brevity I will offer just two points to defend my claims: A. Just one sunbathing session for 50% of the time it takes to sunburn the skin will typically allow anyone except the very elderly to synthesize about 20,000 iu of D3. If at all possible, this is the best way by far to maintain your D levels due to its natural effectiveness at maintaining D levels and for the many other benefits of sunbathing like increased Nitric Oxide in the blood which acts as a vasodilator that helps to control blood pressure. B. The Hunter Gatherer Tribes on the Savanah like the Hadza and the Maasai have D levels in the 60-80 Ng/ml range. I've seen no evidence that their levels that are well above 30 or 40 Ng/mil are causing these peoples all sorts of health risks. They seem pretty healthy to me, and they don't seem to be falling much when out on their daily hunts. Every time she cited D supplementation she failed to cite the type and dose of D. Daily or semi daily supplementation has been shown to increase active circulating D levels a month or two after starting D3 supplementation. D2 supplementation is the only form that can be prescribed, and is usually offered in large boluses separated by a week or more per dose in studies. All the D2 trials I've seen have been ineffective in raising active D levels. I find that the negatively biased D trials use D2 and / or poorly absorbed D3 supplementation to cast D in a negative light. The "fall study" is the only one where she detailed the complete dosage plan. When citing the "study evidence" that she is basing her claims on she constantly uses weasel words like; perhaps, maybe, etc. for the fall risk claims etc. I find that this type of wording is typically used in these trials that have vague findings, in order to alter the narrative on the importance of Vitamin D for whole body health. I could go on for pages and pages, but suffice to say I find that this Doctor, well meaning or not, is a danger to the Health Spans of everyone who watches this video and falls prey to the narrative that she is peddling. Please everyone, look into all the evidence you can find in the time you have available, to see for yourself whether her claims or my claims that Vitamin D is the most important Molecule for overall health other than Oxygen and Water are accurate.

It has now being found that people on Carnivore (high animal fat) diet do not get sunburn and skin cancers. So it was the consumption of seed oils that had been stopping the skin from manufacturing Vit-D when skin is exposed to sunlight. Vit-D is just a skin- sunscreen for your DNA. Just eat animal fats and avoid seed oils, and your body will recover manufacturing Vit-D when you go out in the sun.

@SantiagoHHC The information presented about vitamin D is incomplete and only based on the scientific studies mentioned. Over 40 years of practicing naturopathic medicine, I have come to the conclusion that many of those “scientific” studies, (sure are high level research), but are bias and really serve the interest of the pharmaceutical industry. Who are the individuals behind the studies? Do they serve or are affiliated with the industry? Who sponsors such studies? Unhappily you don’t disclose that information. As a MD, of course, you want to keep your license. If you don’t support the industry, sooner or later some regulatory body will look into your practice. The pharmaceutical industry has never been, and will never be interested in healing people… only in monetary profits. Very, very few of the scientific studies are free from bias and monetary interests. I very respectfully encourage you to look for a study that test high doses of vitamin D3 (daily 10,000 IU) administered along the co-factors needed for the proper utilization of that vitamin D. Vitamin K2, magnesium and zinc, in particular. I bet you will never find such a study.

So, in 2019 I started taking vitamin D daily to support my immune system. Currently I am taking 4000 IU of vitamin D3 (plus K2). In October 2019, I experienced what was one of the worst bouts of “flu” I had ever had. I wonder whether it might have been Covid…. But I survived.

Establishing adequate levels of vitamin D is difficult because there are many factors involved with what may be required for an individual. The only detriment I can see in high dose supplementation is the possible up or down regulation of cell surface receptors in response to vitamin D availability. To my knowledge, there are no studies observing this. I am not a big fan of " fall frequency" studies as I believe them to be useless. Also bone density studies lack the effect of increased exercise and related bone stress factors that enhance bone density over time. Focusing on one parameter in a complex picture of variable vitamin D levels is really not adequate in making claims on MDRs due to the numerous influences of factors that are different in each individual case. I think bi-annuai testing to establish basal levels of vitamin D and later observing effects of supplementation may be of benefit, rather than flying blind, making general assumptions about a population.

As someone who has done epidemiological research on the "vitamin D" status of nursing home residents, I would submit that the term itself is a misnomer, given that it is a prohormone and that its presence in food sources (like that of phytoestrogens) is incidental worldwide. On that basis, I would also submit that the use of "vitamin D (cholecalciferol) supplements" should be referred to as "vitamin D (cholecalciferol) replacement" and therefore as a pharmacological intervention. Conversely, the notion that "normal" levels of serum 25-hydroxy vitamin D (AKA 25-hydroxycholecalciferol or calcidiol) should be based on levels in people living with post-industrial levels of sunlight exposure doesn't seem logical on the face of it. Also, intervention studies suggesting the benefit of "vitamin D" on non-skeletal outcomes such as immune response (for example, European studies suggesting a beneficial impact against morbidity from COVID-19) are commonly done using 25-hydroxycholecalciferol (i.e., the form of "vitamin D" normally derived by the liver from the cholecalciferol that is normally produced and released into the bloodstream by human skin upon exposure to sunlight) rather than oral cholecalciferol ("vitamin D") replacement.
@thetruth99744 ай бұрын
I suppose when people are ill, and during supposed pandemics, it would be more efficient to use 25 hydroxy D3 or 1,25 dihydroxy D3 (active D3) rather than D3 (Cholecalciferol) alone as the former molecules could generate much faster beneficial clinical effects. Otherwise, the body would be required to convert Cholecalciferol into the active D3 via two steps and that would waste time. In "medical emergencies", the best form would be the most active form as the goal is to minimise risks and maximise benefits to patients as quickly as possible. In a person with poorly or non- functioning liver and kidneys , supplementation with Cholecalciferol (D3) would generate a lower yield of active D3 (1,25 dihydroxy D3) with fewer positive and meaningful clinical effects. In individuals with healthy liver and kidneys, supplementing with D3 (Cholecalciferol) should not be an issue as the tissues would have no problem converting it into its storage form (25 Hydroxy Cholecalciferol) as well as the active D3. Not measuring Vitamin D3 levels and neglecting or minimising its importance and role not only in maintaining optimal health as well as reducing the incidence of various forms of chronic diseases are tantamount to ignorance, disinformation and medical negligence.

@@thetruth9974 I can't argue with the value of measuring serum calcidiol levels in general, but I don't think we know enough to assert that oral ingestion of cholecalciferol (never mind ergocalciferol, which is the analog typically used to "fortify" cow milk alternatives with "vitamin D") has an identical physiological impact to endogenous synthesis from 7-dehydrocholesterol and direct release into the bloodstream by the human skin (which is distinguished by a self-regulation mechanism among other things).

I'm not entirely sure about this presentation, but I want to share my experience with vitamin D. Since I increased my vitamin D level to over 100 nmol/L, I haven't had a single cold. I used to get a week-long cold twice a year, which I thought was normal due to seasonal changes. This was six years ago. Before that, I visited my GP because I was constantly feeling tired. After running several tests, he recommended checking my vitamin D levels, which turned out to be 18 nmol/L at that time. I didn't know much about the importance of vitamin D back then, but now I aim to keep my level around 125 nmol/L and have it checked regularly. My mood swings improved dramatically as well. Vitamin D is more than just a vitamin; it's more like a pre-hormone that aids in hundreds, if not thousands, of functions in the body. It also acts as a natural sunblock, and I hardly get sunburned anymore (I avoid using chemical sunscreen products). Also, I never got COVID-19, even though most of my family and friends had it at least once (I did take the initial rounds of vaccines, though). All of this may or may not be related to vitamin D, but this is my experience, and for me, it is convincing enough. The research in this clip should be cited.

I am taking 10,000 IU of Vitamin D plus L 2 per day in order to keep my D at 80. (When I go down to 5,000 per day my levels drops to just 30.) When I see a traditional western medicine physician is always ALARMED at my high levels. However I feel best at 80 my brain and memory is excellent for my age AND more importantly I have restructured my bone mass by 6% as week. I'd be very interested in what you think?

In the beginning of the Vitamin D craze, around 2000 to 2005, some of the data showed reduced falls in the geriatric population. As you can imagine, fall reduction is HUGE in this age group due to multiple injuries and especially the downward spiral that often follows a hip fracture in an elderly individual. Some felt the reduced falls with adequate Vitamin D levels was because of improved balance and other felt it was actually non traumatic fractures of the hip or fumur that caused the falls. The thought then was adequate Vitamin D levels reduced fractures in weak bones that happened spontaneous without trauma. Less spontaneous fractures with adequate Vit D and less falls. Given the recent large population research published in June 2024, thats not the case.
@MikeG-js1jt4 ай бұрын
@@ChadSharkeyNursePractitioner I dont believe falls were reduced at all, I think it only "appeared" that way, because mostly falls are only reported if something bad, like a FRACTURE happens as a result and I think people who had a history of higher levels of vitamin D had just as many falls but less rfractures, thereby seemingly less falls as there were less reports of those falls due to there being no or less fractures due to those falls.

It was my rheumatologist who recommended taking 2000 IUs of Vitamin D daily, as I have osteoarthritis. I just double checked, and it does look like the idea is legit. I can't post links, but I found a paper from 2023 called "Relationship between 25-hydroxy vitamin D and knee osteoarthritis: a systematic review and meta-analysis of randomized controlled trials" and it does seem to confirm that it can keep OA from progressing as quickly. So I will keep doing what I am doing, which is skipping it on days I eat fatty fish. Oddly, my last Labcorp report (2022) gives the reference interval as 30-100 ng/mL. I am at 37.4, and that made me think I was at the lower edge of normal. But seeing your guidelines I guess I'm doing just fine.

I started taking ~8K a day, plus twice a week deliberate sunbathing, in 2020 in an attempt to not die from the virus. Expected nothing, but woke up about a month later to a pain-free hip joint for the first time in years. Turns out VD is indeed an anti-inflammatory, and it can have a significant effect on both RA and also OA pain. My aching back and torn-up plantar area also improved radically. I literally went from limping ~1/4 mile at a time to walking indefinite distances pain free. Nothing else in my life, diet, nutritional intake, etc. changed. And I've done very deliberate tests where I stop taking D. Within about 10 days, I start to experience minor pain in the joints. A week of ~15K a day jump starts my D levels back to an effective range and the pain vanishes. Try bumping your dose, and target ~70ng. The thing is, our immune cells lack a cell-surface receptor found on bone, kidney, and other 'classic' D tissue. The immune cells rely on passive diffusion of D across the cell wall, and this requires higher blood/serum levels. Many immunologists suggest 60ng or better. Give it a try! ;)

Hi Leslie Just a quick personal story from the NHS in the UK. About 3 years ago I went into Day Case Emergency with high blood pressure and had some blood tests. I had been taking Vit D for about 5 years. The Consultant asked me if I had been taking any other medication. I said No (68 years of age at the time now approaching 71.) He informed me that the Calcium in my blood was to high and I should be taking Vit K2 MK7 to help reduce the Calcium in my blood and move it into my bones. Since then each time I have had a number of blood tests and my Calcium levels have reduced and now more or less normal. I am taking Amlodipine and more exercise and blood pressure near normal. Hope you find that interesting.

FWIW I looked at the bone density/D3 study done in Calgary that you mentioned. To my horror I could not find one mention of K2 or MK7 being part of the study where D3 and calcium were being studied to see effects of supplementation on bone density of men and women 55 to 75. Over 300 individuals were in the study. I would suggest a followup to see how many of those individuals had heart issues after the study. The problem is (from studies found elsewhere), without adding K2 MK-7 to the D3, the added calcium is not going to bone: the calcium is likely locating to the heart and causes complications in that muscle. I am angry that my country has such poor regard for good science. I have to wonder if this was done purposely, for the benefit of some pharma pill push in the future..

What nonsense !. At 2000 IU nothing much would show up. Studies rarely advocate adequate amounts. Since I have been taking Vit D3 with Mag and magnesium with it is critical because Vit D depletes mag everything changed for me. So 100 mgs of mag is necessary for every 1000IU of D3. I suspect nothing showed up in the studies because the study did not include Magnesium with the D3 . "'A little bit of harm !!" "Seems"?? Come on ! Your conclusions are simply not valid because you have some false premises in your argument . And it looks like you have cherry picked your studies. Aside from the mag issue, you leave out the most important issue and that is where you live. In northern climates we need supplementation because we have 6+ months of winter. Start with a test on amounts (It is ridiculous to suggest that the levels should not be checked )!!!. We should be aiming for OPTIMAL levels not just over deficient levels . 'Average' is a wrong way look way to look at amounts. It should be optimal. And from research that is between 100 and 150 nms . Your conclusions remind me of the years we were told not to eat butter and now it is found to be critical for C15 . Check your facts again and pick different studies. 4000 IU is minimal and 5000IU is even better when you live in a cold climate.

I'm really glad that this is getting out. Vitamin D orally is really dangerous, in any amount. If I take any at all, it causes my haemorrhoids to bleed, showing how blood thinning it is. Blood thinning like this could easily cause mini-strokes, where capillaries in the brain leak because the blood is too thin. Studies have shown that mini-strokes are extremely common, and mostly go unnoticed either by the individuals having them, or their carers. Vitamin D induces a deficiency of vitamin K, which is needed for blood clotting. Hence taking vitamin D on its own is dangerously blood thinning. Having noted that vitamin D supplementation on its own is dangerous, studies also show that vitamin D in combination with vitamin K, vitamin A and magnesium is preventative of cardiovascular disease, bone disease etc.. Much more could be said on the vitamin-mineral interactions with vitamin D than in the section copied below from Deanna Minich's wonderful chart outlining them, but this isn't the place to go into more detail. Each bullet point, in the original document, has an embedded hyperlink to supporting research. Synergistic Nutrients Vitamin K • Optimal levels of vitamin K prevents some of the problems of excess vitamin D and leads to better outcomes. • Sufficient levels of vitamins D and K lead to reduced risk of hip fractures and an increase in BMD and other markers of bone health. • Sufficient vitamin K and D also improves insulin levels and blood pressure while reducing the risk of atherosclerosis. Calcium • Vitamin D increases calcium absorption. • Along with vitamin K, supplementing with calcium and vitamin D leads to improved bone, heart, and metabolic health. • Calcium and vitamin D also work synergistically for skeletal muscle function. • Co-supplementation of vitamin D and calcium led to an improved response to children with rickets. Magnesium • Supplementing with vitamin D improves serum levels of magnesium especially in obese individuals. • Magnesium is a cofactor for the biosynthesis, transport, and activation of vitamin D. • Supplementing with magnesium improves vitamin D levels. • Deficiency in both vitamin D and magnesium increase risk for cardiovascular disease, diabetes, metabolic disease, and skeletal disorders. Selenium • Supplementing with vitamin D improves serum levels of selenium. Antagonistic Nutrients Vitamin A • High levels of vitamin A decrease vitamin D uptake by 30 percent. Vitamin E • Medium and high levels of vitamin E significantly reduce vitamin D uptake by 15 percent and 17 percent respectively.

My doctor ordered me to take blood thinners, which I have not been doing. Sounds like I should boost my vitamin D intake above the current 2000 IU/day. Seems our nutritional requirements are specific to the individual. You do make a really good point, Dr Kernisan is really misleading people with this video. The situation is far more complex then she lets on, and what she claims to be factual will clearly harm many people.

What about the role of K2 - which is talked about a lot. D3+K2 is recommended together. Since it is so commonly recommended I’m curious to hear your thoughts about it. Can you do a quick video on that? Thanks.

Funny my father well over 80....takes 4 times the "recommended" amount along with K2 and magnesium...and he is fitter than most 50 year olds...walks 10 miles a day as well as going to the gym to row every day....he has NO brittle bone. Maybe he should take less so he can become a feeble 80 year old....

Among the studies cited, was there any effort to include/exclude/account for, simultaneous administration of vitamin K2?

Sure, look up: "Despite hopes, vitamin K2 supplements fail to slow calcium buildup in heart valve"

@@STree42 Well, thank YOU for a reference to vitamin K2 in relation to vitamin D. However, I was asking if, in the video, the doctor had mentioned K2. Did I miss it in the video?

The term vitamin D is not the correct term. This is misleading to people. D2 is different than D3. So far, you haven't mentioned "D3 and K2". Just taking D3 without K2 is dangerous. The research using 2,000 iu a day used an extremely low dosage amount. What did 10,000 iu a day show? And using Zinc, and Magnesium to optimum levels? How many minutes of sun a day does it take to get 2,000 iu? Maybe you should be suggesting that people get more sun. I am disappointed in your video because you are not using correct terminology and recommendations for taking vitamin K2 with D3. The K2 moves the calcium to the right places in the body instead of allowing just D3 to cause arthritis, and frozen shoulder, etc. build up of calcium where it should not be. You are in Big Pharma's pocket.

Ferrittowner....you saved me some typing! was about to mention the same thing! D2?D3? WHICH ONE IS SHE TALKING ABOUT? Keep your levels over 70 and get tested! Mds want us $ick. Go see a functional medicine MD yes yes yes! Also take K2 mk7 want male breasts? Take statins cause youll be low T. Why? testosterone is made from cholesterol which does not cause heart disease. Its trying to patch up endothelial damage etc etc. She says be!ow 20 is low D. total nonesense!!!
@garyssimo4 ай бұрын
So a level of 31 is fine? Ye$ fine for the medical industry with all our low D sicknesses. Get tested!!!! Its a $25 or so test if you have no insurance. All im seeing in my research is keep levels over 50. Many Functional MDs in the know keep theirs at 100 nanagrams per deciliter. 20-30 is critically low.

I wish a study had been done on the effects of Vitamin D on the immune system. I was under the impression that Vitamin D supported immune system functioning and that people with low Vitamin D levels fared much worse during the Covid-19 pandemic for that reason. I currently take an average of 3900 IU daily (supported on alternate days with 180 mcg of Vitamin K2), and my current Vitamin D level is in the low 50s (measured in ng/ml) which is above the range you consider optimal (20-40 ng/ml) but not by a large margin. I am considering cutting back my current dosage to 2900 IU daily and seeing what happens to my Vitamin D level. Also, I see no reason why an older adult should have to wait until they get sick or develop symptoms before they get their Vitamin D level checked. One or two initial baseline measurements might quickly determine if an older person is below 20 ng/ml and suggest the need for Vitamin D supplementation to prevent development of adverse symptoms.

against all studies! But of course she does not know! Anyway she has to prove what she says

What about the positive effect it has on the immune system ??? Nothing mentioned in all your mentioned tests??
