OPSS regularly receives questions about whether dietary supplements—especially those used for bodybuilding and weight loss—could produce a positive result on military drug tests.

Military drug testing begins with urine to screen results, and then additional tests sometimes follow depending on the outcome of the screen. You can get extensive information about DoD’s drug policy and drug testing from the Drug Demand Reduction Program (DDRP), including military testing. For answers about the potential effects of specific dietary supplements on drug screening tests, you can contact your service’s military drug-testing laboratory by phone or email (list below).

Military Service Members should be aware that dietary supplements on the market might contain undeclared drug ingredients—that is, controlled substances that are not stated/ listed on the product label.

You can get more information about “hidden” ingredients from the FDA Consumer Update about products FDA has identified as tainted. There is no way to know if a particular supplement contains an undeclared drug without laboratory testing.

DoD currently has no formal policy on the use of dietary supplements and no list of either banned or safe supplements. For more on this topic, see the OPSS “prohibited list” web page.
