That is misleading. The purpose of taking high doses of vitamin D is to achieve an optimal vitamin D supply in a short period of time. Once you have reached this level, you should of course not continue taking high doses, but take a maintenance dose. And off course, this all presupposes that you have your levels tested.

You are wrong on this matter. Vitamin d3 toxicity happened only to those individuals who took 60k iu per day for several days due to ignorance, and you conveniently mentioned those news without fact checking what really happened. Other factors you missed are : 1. Skin colour 2. Geo location 3. Sun exposure - some people like me prefer to stay out of sun. I take around 10k iu per day, and my blood test gave me a level of 77, so I decided to cut it down to 5k iu per day, then it dropped to 55. So I am back on 10k iu again. How much d3 supplementation a person needs is a very individual specific goal, either they should get their blood tested done every month to check their levels or take right dose under medical supervision:

I have improved my joints so that now at age 76 I think of them as perfect (and I do squats, and sissy aquats in my strength training). The problems I had when younger weren't critical, but I noticed things. 5' 000 IU of vitamin D3 during a decade ot two were the most important thing, I think. But my full "joints stack" is: This is my supplements aimed at skin, joints, tendons, facia and bones: Magnesium (up to 420 mg for men. But not so much that it upsets the intestines. Food is better, of course, but rather deficient nowadays.) Vitamin D and K2 (5000 IU resp 200 ug of MK7) Hydrolyzed collagen 12 -- 15 g and some vitamin C Boron 3 .. 6 mg I did get my first tendinitis (biceps tendon at the front of the shoulder) before I started with hydrolyzed collagen. Too much plance pushups in rings when my gym closed and I started doing them outdoors., but I won't think I would have got it if I had known that I needed more collagen at my age. Well maybe second tendinitis, since I had some issues with the superscapularis tendon decades ago. That's fine now too, since I started with regular hanging knee or leg raises. Hanging and mills with Indian Clubs (and heavy steel clubs) is really good for maintain the shoulders, that weak spot for us older! But I think this works well only with something like my joints nutrition stack. Do you Know that we need copper for building proper collagen? Even so, I don't count that as belonging to my joint stack, since we usually get enough of that and don't want to much of it.

@@stx7389 The only known toxicity from vitamin D is too high blood calcium levels. That normally only happens with over 30'000 IU of vitamin D, or with it combined with calcium supplements. It's very likely that vitamin K2 makes that risk go away, but no one has researched that. My general recommendation is to combine supplementing magnesium, vitamin D3, and vitamin K2, and to get calcium from food. Magnesium is needed, and consumed, while processing vitamin D. So you might not get the right blood level of 25(OH)D and 1,25(OH)D without it. Vitamin K2 is needed to activate those 17 known calcium handling proteins created by vitamin D. Without it the body doesn't handle calcium correctly, and that's bad! Vitamin D increases the body’s uptake of calcium, so you usually don't need supplementing with that. I suggest that 5'000 IU of vitamin D is pretty optimal for most people. The ideal is to meassure the level of 25(OH)D after 3 months and adjust the level to get into the range 40 - 60 ng/ml (multiply with 2.5 to get nmol/L, which we Europeans utilize). But, of course, the guidelines tells us that max dose is 4'000 IU. That and the idiotically low RDA is why this subject is so confused! Higher blood levels aren't dangerous. But I wouldn't keep the level above 80 ng/ml. That's medication in my view! Most people can get the RDA from food, but need the sun to get an optimal dose.. We actually don't usually feel even very low levels of vitamin D. That's probably why so many people can be deficient without doing anything about it. We even think getting a few colds every winter, and needing a walker at age 75 or 80 is normal!

My strictly anecedotal experience with megadosing D3/K2 + Mg: ten years ago I was diagnosed with inverse psoriasis of the inguinal area at age 54. For years I tried to manage it using various topical ointments, both Rx and OTC. It was not until I started taking 20,000 IU of D3 each day (along with commensurate amounts of K2) that I experienced lasting relief. I kept up this regimen for about two years, after which I decreased to 10,000 IU, which is my current dose. I've never had any of the symptoms of D3 toxicity, but I'm mulling over whether to get a blood test, just to get an idea of where my longtime regimen has left me. Update: soon after posting this comment, testing revealed that my D level is 106 ng/ml--slightly elevated but nowhere near the danger zone (which I've seen defined as either 150 or 200). So take my experience with years of high-dosing D3 into account as you weigh your own regimen!

In winter of 2022, my vitamin d supplement was exhausted, and I could not locate my preferred (400iu) dosage supplement. For two weeks my daily intake surged from about 2000IU to about 5000IU. I soon noticed that pain in a hip joint, damaged in elementary school, returned. As soon as I re-established my customary vitamin D dosage (from a supplement sourced online), the hip pain resolved (has not returned).

This part is significant, it says adding more vitamin d works for normal-weight individuals. Just because it didn't work for all individuals as a group, doesn't mean it doesn't work for every individual.

It seems that my 5400 IU of vitamin D3 is a little to low. I get only to 45 ng/ml of 25(OH)D in the spring, before getting any sun. I consider 40 - 60 ng/ml as a very good range,, but there are signs tin the research hat 70 ng/ml is better against cancer (e g breast cancer). I consider 5000 IU as a very good supplementing dose to start with, until measuring it (after at least 3 months). If I remember correctly you take about half that dose. Have you measured your level? I live in Stockholm, Sweden, and we have no vitamin D from the sun in a very long winter. That, of course, makes a difference. Next autumn I will increas my dose of vitamin D, aiming to get higher w8thin my range. I calculate that each 1000 IE increases the level about 5 ng/ml, or a little less for me. So I guess my supplementation range is 5'000 - 10'000 IU. Above that, I still consider it medication, which might need supervision. Sorry to say, I think your talk about megadosing is detrimental to our health in general. It would be better to try to estimate an optimal dose. Everyone of us who have studied this subject knows that the current guidelines are blatantly wrong, and that their max dose of 4'000 IU actually is a good minimum dose. Unless you are out in the sun when it's at least 45° above the horizon, that is. By the way, those 40 - 60 ng/dl is where people gho are outdoors get if they don't cover up to much in countries we evolved in.

Many doctors would warn you that your level is too high. If they tell you tp stop supplementing, they are wrong. If they tell you to reduce it slightly they may actually know something. You could lower the level slightly by skipping one day a week. My reccomendation is to take vitamin D almost daily, which means skipping single days is OK.

For that, you need a chemistry analyzer with an appropriate reagent pack. The iSED is fast, reliable machine that is suitable for STAT testing.

@@seascape35 Milk, vegetable drinks, and some fats are "enriched" with vitamin D in Sweden, but in unsufficient amounts. In the order of 1 ug/100 g. That's about 40 IU. One liter of milk would give us that idiotically low RDA of 400 IU. That would raise the blood level of 25(0OH)D by a paltry 2 ng/ml, and we want it to be at least 40. Pretty insignificant, I think. About 5 - 10% of what's needed. I have always regarded "enrichment" as an idiotic practice because not all of us consume these products. And also, it's usually made because processing has destroyed the natural content of those and other things. It's a way to hide these kinds of detrimental processing by false claims of vitamin contents. The rational thing would be to supply us with a free multivitamin, and let us do what we want with those things.

'Primary Care' professionals in the UK don't appear to offer a Vitamin D blood test, which is why I had to pay for it myself... glad I did. It was rather high (137 nmo/L) (although the lab that tested it says the cut-off is 200 nmo/L and considered it fine). So I have stopped supplementing now. The UK has had zero sun for the past 7 months. ☹
@larsnystrom66983 ай бұрын
If you think it's too high you shouldn't stop supplementing. You should titrate it down to where you want it. I want my levels between 40 - 60 ng/mL. (Multiply with 2.5 to get nmol/l). Your level is 54.8 ng/mL. It's well known that it's not just the level that's important. You also need it almost daily. So it's a bad idea to just stop to get the level down.

I just checked my old vitamin D result. It's said normal = 30 - 70. If you do not check how do you you know whether your level is in "normal" range. Let's say your level is 15, if you take 1000IU per day, after 3 months, you need find out what is the result. Based on my experience, I take 5000IU per day, and the result is still under the normal range. as far as I know, each individual's absorption of vitamin D is different, some even mention that taking along with magnesium can yield different result. furthermore the definition of "megadosing" somehow different. for me over 10000 can be called megadosing. so taking vitamin d is depend on your goal, maintaining you level is not equal to increasing your vitamin d level. to know for sure, you have to test/check.

There are some interesting points here. It seems that many beneficial health outcomes of high Vit D levels may be due to being outside, working outside or exercising outside rather than the Vit D itself. This is understandable, as staying indoors all day may be a sign of bad habits or bad health. You are also right that there are many claims about high doses of Vit D which are obviously not substantiated according to the studies you discussed. However, the question remains how to reach optimal levels and this is where I disagree. Maybe you only have in mind New Zealanders like yourself, but conditions all over the world vary greatly. In my country, half of the year there is not enough sun to produce Vit D naturally, however, there are neither fortified foods nor official recommendations to supplement with Vit D daily. Moreover, people of different ethnicities live here - white people, black people, Muslim women who cover most of their body even in summer, people who wear sunscreen all day like you and so on... Telling all of them to take 1500 IU without ever testing may be reasonable from a health system economic perspective, but for the individual it is always better to get tested. And I see many comments here stating that the "mini" doses did not do much for their low levels. The question remains whether there are benefits of being outdoors, or of UV radiation, that cannot be covered by Vit D alone. It is just my personal opinion, but the science about the excessive use of sunscreen might one day show more harm than benefit. With excessive I mean outside of the hours with high UV index.

Since I live in Stockholm, where we have no sun during a very long winter, I have been supplementing with 5400 IU of vitamin D3 for decades. I finally measured my level of 25(OH)D this spring, before the sun have had any effect. It was 113 nmol/L, or 45 ng/mL. Each 1000 IU typically raises the level about 5 ng/mL. And without any sun you will probably not have more than 20 ng/mL. So, 5000 IU might typically give about 55 ng/ml. I consider 40 - 60 ng/mL as good values, although higher aren't dangerous. Above 70, or 80 shouldn't be needed, I think. The reason for measuring is that some individuals need much more, and some much less. I guess measuring once or twice is enough to know which kind you are. It takes something like 3 months of supplementing, or changing it, for reaching a plateau for vitamin D. Having to high or to low level that short time shouldn't be any problem. Magnesium and vitamin K2 is needed to get the entire system to work. Magnesium is actually consumed when the body does it's thing vidh vitamin D. And vitamin K2 is needed to activate the calcium-handling proteins created by vitamin D.

Vitamin D is non-toxic. Side effects appear when vitamin D in so-called "megadoses" is taken without cofactors, primarily magnesium and vitamin K2 (MK-7). Plus, many (if not most) people start taking vitamins when it’s too late already and they already have a disease.

Dr S, your advice is possibly reasonable for the 8% who don’t have low blood levels. For the 92% the important message, that it’s super important to supplement with D3, did not get through clearly with your generally negative tone here. Also in the simple model of the calcium cycle (D brings it in, K2 puts it in the right place, and A takes calcium out of the system) the toxic effects of D3 are IN THE ABSENCE of K2 supplementation. You did not address this so, well, of course you can have high D leading to hypercalcium problems, that just means you have to put the calcium in the right place (bones not arteries) which is the function of K2 (activating osteoblasts, for example). Your argument did not address this which is the very basic idea of D+K.

Love this guy and his channel but this is the only clip I have to hard dislike. There's plenty of studies made during covid regarding the importance of vit D.

Her calcium levels are normal and I saw it with my own eyes as her lesions decrease in size. She is doing pretty good. She is kept under constant surveillance, nothing negative so far at 100k UI vit D. I know it's anecdotal but it's actually not when you see it in a friend! It's shocking actually. I myself was taking 6000-8000 UI during covid for about 1-2 years. No changes in calcium blood tests or in urine tests. How can we explain this considering the conclusions of this video?

Despite the fact that you're telling me the opposite of what I've read again and again, I'm still gonna go with the 40-60 mg/ml considered optimal, not the most conservative recommendation of 30 ng/ml. I need to supplement about 5000 IU daily to maintain a level of 50 ng/ml. Before I started supplementing, my level was at 21 ng/ml, and I usually didn't even wear sunscreen back then. The dangers of megadosing are also exaggerated, or let's put it that way, taking 5000 IU is far from megadosing. In a control trial, even longterm supplementation with 10,000 IU had no negative effects and while there is no benefit to take more than that, even reported toxic effects at yet higher vitamin D dosages seem to be exceedingly rare. "Good levels of vitamin D are a marker of good health" - it's pretty obvious that the missing link or cause of good health is sunlight exposure. See red light therapy or photobiomodulation.

Excellent! I started watching expecting to strongly disagree but I couldn't fault any of it and in fact, I learned something. I'm 60 and I supplement with 5000IUs per day. I had a blood test a little while ago and D3 was one of the things they tested for. My result was about 95 nmol/L, which I'm happy with but I now feel that a little lower would be fine so if anything, I'll buy a slightly lower dose next time. Maybe 4000IUs. I also take K2, magnesium and calcium (I don't drink milk and seldom eat cheese). I've seen D3 supplements containing 10,000 even 50,000IUs! I never thought that was a good idea. You've confirmed that. I fear a lot of so called "bio-hackers" are going to significantly shorten their lifespan with all the mega dosing they're doing. A more worrying fave is megadosing B3 (niacin) and related compounds. Excess niacin is converted into the substance 4PY, which can contribute to heart problems by triggering inflammation in the circulatory system.
