Over the past 5 years, as I have diligently read the new science as it relates to wellness and nutrition (with a few a exceptions) I have experienced an almost complete about face in my belief and enthusiasm for supplements. The past month happened to bring us a deluge of new data from several large, very powerful randomized clinical trials (the only type of study that can really tease out the truth) that have highly reinforced my current views. The conclusions of these reports are highlighted as follows:
· The long-term use of B-vitamin supplements to include folic acid proved to be of no benefit to lower a woman’s risk of cancer (JAMA, November 2008).
· High dose B-vitamin supplements (folic acid, B-12, and B6) did nothing to slow cognitive decline in those with mild to moderate Alzheimer’s’ Disease (JAMA, 2008).
· Long term use of vitamin C and E supplements in healthy adult males was of no benefit for cancer protection (American Academy of Cancer Research Meeting, November 2008).
· Long term use of vitamin C and E supplements in healthy adult males was of no benefit in reducing the risk of heart attacks, strokes, or cardiovascular death. Those taking vitamin E had a slightly increased risk of hemorrhagic stroke. (American Heart Association 2008 Scientific Session)
· Long term use of Gingko Biloba was of no benefit in preventing or slowing the development of dementia in elderly subjects (JAMA, November 2008)
Americans currently spend billions of dollars on the above supplements.
