I searched the site and found a lot of discussion about vitamins but nothing referring to clinical studies on their effects.

Does anyone have a source for clinical studies showing the effects of daily multivitamin supplements? I searched NIH and found one study of over 5,000 physicians over age 65, where daily multivitamin supplements did not affect cognitive level, or change of that level over time.

Is there anything that people can point to with peer reviewed studies? Thanks. I know there are some health professionals on this site, I hope they chime in.
