I came across a certain internet doctor Garrett Smith claiming D3 is rat poison. So I looked into it, and sure enough, high dose D3 is in rat poison.
Does this mean it could have negative effects for humans as a supplement? Though I think many vitamins can be toxic at high doses. Why do they use D3 then?
Smith also hinted that what our body produces from sunlight is very different from what we get with a D supplement.
Thoughts?
