I started using Vitamin D supplements after I read an article about a Dr. at Atascadero State Hospital. He noticed that some of his patients had low vitamin D. He started giving it to them all and got remarkable improvements. (Sorry I couldnt find the article. That article of others noted that the normal range for vitamin D tests is too low. Someone who is low normal is probably deficient. Vitamin D is not just for rickets. A deficiency can cause all kinds of other nonspecific problems.
