There has never been a case of clinical vitamin D toxicity from diet. A couple of labs are labeling high vitamin D levels "toxic"; most of the pathology community thinks this is misguided. Glad you've got some good habits; sunscreen as needed. ...Read more

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. ...Read more

I have been taking vitamin c and vitamin d together for a year, is it okay?Did I overdose myself? If so, how would I know?

The adverse effect of too much vitamin D is nephrocalcinosis, calcium deposition in the kidney, but that also is very rare. Almost half the population in the US have vitamin D levels which are not optimum. Get a 25-hydroxy vitamin D level. ...Read more
