Harvard Newsletter Cautions Against Brain Supplements

BOSTONThe December issue of Harvard Men's Health Watch explores brain health supplements, concluding many lack solid scientific evidence. Out of folic acid, vitamins B6, B12, C, E, coenzyme Q10, Gingko biloba, fish oil, curcumin and coconut oil, the review said only vitamin E provided "good evidence that it treats cognitive decline or dementia." The report said none of the supplements have good evidence of preventing cognitive decline or dementia.

"There are a lot of things out there for which we have no data on whether they are safe or do anything to help," said Dr. Gad Marshall, assistant professor of neurology at Harvard Medical School. Instead, Marshall recommends a Mediterranean-style diet to help maintain mind and memory.

However, clinical studies continually tout the brain benefits of vitamins and minerals, including vitamins E, D and B. INSIDER features "Brainy Botanicals," "Heady Hormones, Vitamins and Minerals," and "Fat Head" describe key ingredients that may reduce the risk of age-related cognitive decline and depression.
