The US Food and Drug Administration (FDA) needs more oversight authority to police dietary supplements and foods that contain supplements, according to a Government Accountability Office (GAO) report.
The March 5 report called for additional FDA regulatory authority over dietary supplement manufacturing facilities and expanded reporting of adverse health effects of these products. The report also recommended that the FDA issue guidance to industry to clarify which supplement ingredients require safety documentation before they can be marketed and also that the agency take steps to improve consumer understanding about these products (http://energycommerce.house.gov/Press_111/20090302/gaoreport.pdf).
