A member asked:

I took 1000 ui of vitamin d and had dirhaea, i tried lower dose 500 ui, but still, why is that? could that be overdose? i don't get much of sunshine.

Not overdose: It is safe to take 1000-2000 IU of vitamin D3 every day so what you took was not an overdose. Vitamin D can cause loose stools in some people. Try taking the 500 IU daily with your largest meal of the day. If that does not work then see your doctor for a vitamin D level to make sure that you really need to take it.
