Is My Multivitamin Doing Me Any Good?

Date: July 2, 2015


“In a word, no,” says Johns Hopkins nutrition expert Edgar Miller, M.D. “Our review of research outcomes from various large-scale trials showed there’s nothing to support claims that multivitamins and supplements prevent chronic disease, cancer or dementia; they could also have a negative impact. High doses of vitamin E, for example, put men at greater risk of prostate cancer. There are exceptions: Folic acid is important for pregnant women to prevent birth defects, and people who are on medications that interfere with the absorption of some micronutrients can benefit from certain supplements—ask your doctor. If disease is a worry, change your eating and exercise habits to improve your health.”
