Vitamin D,Miracle drug?

by Roc » click here for full post

The New York Times of February 1, 2010, ran an article titled “Vitamin D: Miracle Drug: Is it science, or just talk?” The author writes, “But don’t start gobbling down vitamin D supplements just yet. The excitement about their health potential is still far ahead of the science. Although numerous studies have been promising, there are scant data from randomized clinical trials. Little is known about what the ideal level of vitamin D really is, whether raising it can improve health, and what potential side effects are caused by high doses.“ The author adds many short quotations from distinguished scientists. Having been similarly quoted in the past, I know how such statements may not represent the scientist’s view. After reading that article, concerned friends have asked me whether taking vitamin D supplements is worthwhile.

This is the entrance page to supervised literature reviews done by Beloit College students. I suggest you use the find command to search by key words. You can also see them sorted by main subject here. Most were done in connection with a biochemistry/nutrition course, Chem127. Read the disclaimer for Nutrition Investigator – these posters are not intended for medical advice, only as background to discuss with a qualified health professional.
