    anything up to 4000IU is "safe by the doctors" but lets be real, its 2024 who the frick believes doctors nowadays

    I can suggest anything up to 20k IUs because I seen people on it for 6months+ and it doesn't have those hypercalcium issues.

    Overall? I take either 4000IU or 8000IU depending how I feel about it that day.

        if youre worried about 5kIU just finish the entire bottle taking one a day and get your levels checked, it will boost it to a good level and then you can cruise at 2-4k after that and be fine. just take it with vitamin K.

    the proper advice is, test a 1k- 2.5k for 3 month and them make an vitamin D test.

      if you were to follow any sort of a target or guideline i would follow the research in europe. The US has a way lower threshold of what they think is a normal vitamind D level. A moderate blood serum level of vitamin D in america is bordering on the low end in europe. and it isnt just europe, there are other boards of medicine in other regions that think we need more than what american doctors say we do.

      see here, the opposite is the case, the levels that are considered high levels in america would be considered more moderate levels in europe. you have it backwards.

          not clicking your random website link. The last time i researched this which was a handful of years ago, american standards of low moderate good and very good vitamin D levels were lower than the european standard was. Either your link is wrong or in the last few years america finally got up to speed with the rest of the world. either way it doesnt matter because my point i made was that america has NEVER had a higher vitamin D blood serum guideline than other countries. EVER.

            No, but I was never criticizing American guidelines. I was criticizing the propensity of American individuals, encouraged by their irresponsible pharma companies, to take excessive doses of most things. If I go on iherb I can find two dozen brands selling zinc at 50mg and even a couple of insane 100mg options. Similarly, there are brands selling vitamin D up to insane levels like 50'000 IU. Only in America.

              youre just uneducated. there being large vitamin D3 pill has nothing to do with the rest of the supplement market being a shitshow. If you have chronically low vitamin D levels, it isnt something you can fix in a month or two. it can take months or half a year. especially if you were only taking something like 1000 IU a day or 2000 IU. for some people only taking 10000 IU or 2000 IU wont even improve it, because its just their maintenance dose. even 5000 IU which sounds like a lot is still going to take a while. the reason why they make 50,000 IU Vitamin D pill is that you need to take stuff like that for a few weeks to jump start to a level thats approaching being normal.A doctor will prescribe you the same thing, except it usually will always be in the inferior D2 form. It takes a long time to build up enough vitamin D that it becomes toxic and thats where studies come in from people around the world who absorb amounts we would assume to be toxic who have levels way above the american standard of high, who are in peak health and live totally healthy lives. im talking like double the american standard of the normal acceptable range.

    Harsh's IST worksheet. 2019. I don't think anything's changed other than the emphasis on the Cholecalceferol and taking it with K2. While vitamin D3 helps your body absorb more calcium, vitamin K2 helps your body transport it to your bones and teeth rather than letting it sit in your arteries and other soft tissues in your body.

          As for vit D, i've seen some arguing that supplements are shit and only food sources+sunlight (to activate it) are any good. Still gonna try supps to see how it feels.

            i can verify that vitamin d pill worked because i got my vitamin d levels to a much higher level by taking them when i realized my levels were absymal. i didnt go outside more i just took a daily supplement. There isnt enough vitamin D in food to signifigantly change your blood serum levels, you would need to eat shitload of food to do that and my guess is it would need to be like 2 or 3 things that have a high enough level to count.

                realistically how much of what food would you need to eat every day to do this? it takes months to get a low vitamin D level back to normal levels. What specific foods are you suggesting eating and in what quantities to do this? do you have a single source? I can see going outside every day for a half hour in conjunction with eating some of that stuff working, but it would only work because most of it is coming from the sun.

                Even if you go out for a half hour every day, it only works during certain months of the year, and you need enough skin exposure for it to work. vitamin D supplements work.

    First you get tested, never start randomly eating supplements, its dangerous and 99% of the time completely useless.

    Get tested, then start eating, try to correct it with diet first, then test again. Take the pills/capsules as a last resort and if you live up north.

    if you want to do it right, get bloodtest for your levels(yes, you can test your vitamin levels, it is just rarely done with how cheap pills are), then start supplementing accordingly (4k seems to be biggest commonly sold dosage, so might be that if you are low), then redo bloodwork after few weeks to see if dose is ok, then act accordingly.

    I think Vitamin D is such a scam. Somehow white people lived in much darker Europe and lived perfectly healthy even vital lives forever but now we all live in much sunnier America and we all need to supplement Vitamin D because we don’t get enough sunlight? I don’t buy it. Either there’s something else causing Vitamin D deficiency or we simply don’t need it.

      they were probably outside enough that even with the severely diminished sunlight they got enough of it by sheer brute force of being outside every day for some amount of time. if the theory is correct that they developed lighter skin because they needed vitamin d, it means that people were probably dying who couldnt get that extra little bit they needed to boost their immune system or function correctly/ have strong bones.

          there are a thousand responses to your post about jobs and regions lifestyles and times of year where a simplified answer like that isnt a practical answer. completely detached from reality. for the majority of people your response is moronic. if you work a 9-5 job you arent going to be outside during the points of the day where you can get much sun. if you work nights you probably arent either.

          even if you have a job where youre outside all day, you are covering up enough of your body with a uniform often times that you would still need to supplement to some degree. it isnt enough either to just go out on the weekends for a hour or two in your backyard with your shirt off. its a big step but most people from their life structure need to still supplement.

      yeah i agree you should get your vitamin D levels tested once a year if not twice. but it isnt rocket science to tell someone that american guidelines for whats optimal is in conflict with most of the world saying you need more. Lots of US doctors use outdated research/information so you have to do your own research if you actually want to be healthy. thats just the way it is. this stuff isnt abstract or anything all the information is out there in published research.

        Listen I think doctors are largely frauds and I don’t have much faith on modern “research” (like anyone who was even slightly paying attention during COVID) or pubmed bullshit. But you simply can’t have all the context just by reading papers. You can find one study that says 20,000 IU of D3 is a-okay. The next day another study comes out saying anything over 5k will calcify your arteries. Now you have to read each study and compare the sample groups, methodologies, funding sources, etc.
        Another big part of this is finding the RIGHT doctor, there are plenty who keep up to date in their fields. The very first thing you should do when you decide to get serious about your health is find the best doctor you can. It can take some time but they’re out there. My doctor is familiar with Ray Peat’s work, for instance, which was hugely reassuring for me.

          i agree with all of your points, i wasnt telling anyone how much to take, only bringing it to their attention that the levels of vitamin D in your blood that many doctors consider to be within normal range in america are considered to be bordering on low in other countries. Its worth being aware of. And there have been no negative side effects found in maintaining the levels considered to be optimum in other countries. one could argue its a better idea as a buffer during winter months to have that since it will deplete over time naturally if you rely on going outside to get some of your vitamin D.

        if your doctor wont even give you a fricking vitamin D blood test thats bordering on malpractice. its gotten to the point where almost all americans are deficient in vitamin D, make your case and tell them you want to get it tested because (i assume) you dont go outside much. ask your insurance company for a new doctor if you need to and tell them that they wont even give you a vitamin D test. If you want the test bad enough you need to explain things about your life style which would make a vitamin D test sound like a good idea. if they still say no, tell them youre going to start supplementing it and you want to know what your level is.
