The FDA does not approve nutritional supplements and any company that claims otherwise is lying. Here's a direct quote from the FDA website:"The U.S. Food and Drug Administration (FDA) does not have the authority to review dietary supplement products for safety and effectiveness before they are marketed.If the dietary supplement contains a NEW ingredient, manufacturers must notify FDA about that ingredient prior to marketing. However, the notification will only be reviewed by FDA (not approved) and only for safety, not effectiveness.Manufacturers are required to produce dietary supplements in a quality manner and ensure that they do not contain contaminants or impurities, and are accurately labeled according to current Good Manufacturing Practice (cGMP) and labeling regulations."
