A member asked:

What are the names of vitamins d im going to bay?

A doctor has provided 1 answer

Vitamin D, D2, or D3: It may be called vitamin d2, d3, or cholecalciferol, but it should be fine if it just says vitamin d. Normal adults can take 1000 units a day, but vitamin-deficient patients may need more.
