The following are substances that have at one time appeared, or currently appear, as ingredients in products labeled as dietary supplements that FDA or the U.S. Armed Services have disallowed for one reason or other. In addition, all prescription drugs and controlled substances * are not permitted for use in or as dietary supplements, but only a few are listed here. Since DoD follows federal guidelines with regard to dietary supplements, this list is provided to help Military Service Members keep track of things to avoid when considering dietary supplement products.

For a list of controlled substances, please visit the Drug Enforcement Administration website to download the current version. Other ingredients in this list might have had adverse events associated but not reported to FDA.
