Do you just swallow a pill?

  Yep, it's the most insanely underappreciated public health intervention in history.

    Many public health people say that iodized salt takes those laurels. Or maybe its the most bang for the buck, at an estimated $.05/person/year to prevent intellectual and developmental problems. Guess it depends on exactly what you mean. https://en.wikipedia.org/wiki/Iodised_salt https://en.wikipedia.org/wiki/Iodised_salt

  Vitamin D is a fat soluble vitamin isn't it, so maybe we need more than just swallowing a pill. We have very bad data from most Vitamin D studies suggesting it does almost nothing. The people with high natural Vitamin D who spend 1-2h per day (exercising?) outside might just imply a proxy for a healthy lifestyle. Alternatively Vitamin D might need to be a) taken in higher quantities than the studies have done b) taken with fat c) taken with other supplements K2, NAC, Magnesium (which people are also deficient in) etc. We could probably come up with other theories why the trials and results don't add up. Nice to see an actually positive result from supplimentation.

    >> who spend 1-2h per day (exercising?) outside might just imply a proxy for a healthy lifestyle. Try living in the north. Being outside, exercising, and sunlight exposure are three unrelated activities for at least six months of the year. Vitamin D supplements are the only way short of tanning lamps.
