The Government Accountability Office (GAO) has issued a report entitled “Dietary Supplements: FDA Should Take Further Actions to Improve Oversight and Consumer Understanding.” The GAO found that while FDA has taken some steps to identify and act upon safety concerns related to dietary supplements, several factors limit the agency’s ability to detect concerns and remove products from the market, including lack of mandatory recall authority and the difficult process of demonstrating significant or unreasonable risk for specific ingredients. The GAO recommends that the FDA request additional authority to oversee dietary supplements, issue guidance on new dietary ingredients and clarify the boundary between dietary supplements and foods with added dietary ingredients, and take steps to improve consumer understanding of dietary supplements. The FDA generally agreed with GAO’s recommendations.
