Multivitamin Supplements Don't Help You Live Longer, Major Study Shows

A study from the National Institutes of Health (NIH) analyzed data from nearly 400,000 healthy adults over 20 years and determined that "multivitamin use to improve longevity is not supported." The findings were published in JAMA Network Open. ABC News reports: The study found no evidence that daily multivitamin consumption reduced the risk of death from conditions such as heart disease or cancer. Rather than living longer, otherwise healthy people who took daily multivitamins were slightly more likely (4%) than non-users to die in the study period, according to researchers. Researchers reported nearly 165,000 deaths occurring during the follow-up period of the study, out of the initial group of 390,000 participants. The study, however, did not analyze data from people with pre-existing vitamin deficiencies. "What this study shows is that, generally, multivitamins aren't going to help you live longer," Dr. Jade A Cobern, MD, MPH, board-certified physician in pediatrics and general preventive medicine, told ABC News. "Even though the cost of many multivitamins isn't high, this is still an expense that many people can be spared from."
