I started taking vitamin d when I started my professional life as a software engineer after my studies. I had a minor winter depression, and I’ve never stopped taking. Since then I’ve had no colds at all. Of course this is anecdotal, but I think a LOT of people in western society could benefit from taking 2000-4000 IU daily throughout the year

vitamin D deficiency is rampant. head of cardiology at one of the most renowned hospitals takes 5000 IU daily, been for decades.

  Don't hesitate to take 10-15k a day for an initial period of couple weeks if you think you might be deficient. Vitamin D requirements are notoriously understated and the supplements underdosed

  I think that copying the behaviour of hospital department heads could lead to propagation of some truely idiosyncratic behaviour.

Same, haven't gotten a cold since I started taking vit D supplements; or when I did get anything close to cold symptoms it was very mild and didn't last more than a day or two. I had done the blood test for vit D and I was very deficient -- like many people. It's worth noting that it may well be the only vitamin where deficiency is common in developed countries and where supplementation has plausible benefits. In fact the only thing missing to positively say that supplementation is beneficial is that while deficiency is known for certain to be associated with major issues, and that supplementation has recently been shown to be beneficial in some cases, it's not been demonstrated that supplementing in the general case translates into better outcomes. However, since it's certainly not been demonstrated that it doesn't, it seems quite a bit more plausible than it does than otherwise. The question is, what are the risks of supplementation? For almost everyone, and at doses that are not completely insane to begin with, the risks seem to be close to zero. But there may be some genetic factors that make a small minority susceptible to overdose.

  > Same, haven't gotten a cold since I started taking vit D supplements; or when I did get anything close to cold symptoms it was very mild and didn't last more than a day or two. Funny, those "I never get ill" claimers always do get ill if you follow up, "just very little, it's nothing".

    Sometimes I get a runny nose, my throat is slightly sore ... and it's gone the next day. Could be an allergic reaction, too much vaping, inhaling something, or an infection not taking hold; no idea. It's an entirely different experience from getting an infection with a fever, fatigue and so on.

    That’s actually a pretty good outcome.
