Many military service members love dietary supplements.

Steeped in a culture of fitness and optimal performance, military professionals take dietary supplements at far higher rates than their civilian counterparts. Studies show that nearly two in every three service members takes some sort of daily dietary or herbal supplement.

Some supplements include basic ingredients like protein or multi-vitamins. Troops cite reasons for taking supplements that include "fitness, physical appearance, and occupational demands," according to one 2021 study in the Journal of the Academy of Nutrition and Dietetics.

Yet, many others contain unfamiliar and unregulated ingredients that are hyped as tools for boosting testosterone and sexual performance, or speeding up the natural process for body building and losing weight.

"Many of these can be contaminated with undeclared drug ingredients, steroids, steroid-like ingredients and/or prescription drugs," said Dr. Melissa Givens, director of the Consortium for Health and Military Performance (CHAMP).

Dietary supplements - and their sometimes dubious claims of health effects - are regulated differently than conventional foods or drugs by the Food and Drug Administration (FDA).

All dietary and herbal supplements claims are labeled with the disclaimer: "This statement has not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure, or prevent any disease."

Dietary and herbal supplement firms are responsible on their own for evaluating the safety and labeling of their products before marketing to ensure that they meet all the requirements of the Dietary Supplement Health and Education Act. FDA is responsible for taking action against any adulterated or misbranded dietary supplement product after it reaches the market.

Marketers and advertisers often target service members with flashy logos and quick-fix claims about these supplements. That's why, to counter any health-related misinformation, CHAMP has created an online reference tool called Operation Supplement Safety.

Here you can find a list of prohibited dietary supplements that are considered high risk or are unapproved drugs. You'll also find the brands and names these supplements are marketed under.

DOD follows federal regulations on dietary supplements.

"Operation Supplement Safety's mission is to provide the best evidence-based information about dietary supplements to service members, their families, health care providers, and leaders to achieve human performance optimization," Givens explained.

"OPSS's goal is to provide the tools and resources to help users make informed decisions about dietary supplements."

OPSS includes an "Ask the Expert" feature that allows users to post questions about supplements directly to health experts.
