Label Accuracy and Quality of Select Weight-Loss Dietary Supplements Sold on or near US Military Bases

Background/Objectives: Sixty-eight percent of service members are living with overweight or obesity, some who may not consult a healthcare provider when they decide to lose weight. Instead, they often turn to weight-loss dietary supplements for self-care solutions. The purpose of this case series study was to examine the label accuracy and quality of select weight-loss dietary supplements sold on or near US military bases across the country. Methods: Weight-loss dietary supplements (n = 44) were selected and purchased in GNCs, Exchanges, and Shoppettes across 12 military installations from March 2023 to January 2024. Liquid chromatography-mass spectrometry was used to verify the label accuracy according to the Supplement Facts listed ingredients and whether they contained any ingredients prohibited for use in the military. Product label claims were analyzed using the Operation Supplement Safety (OPSS) Risk Assessment Scorecard. Results: Thirty-six products (82%) had inaccurate labels. Twenty-seven (61%) had ingredients listed on the label not detected through analysis. Sixteen products (36%) contained hidden ingredients. The four products purchased within one mile from the base listed multiple prohibited ingredients on the labels, with all detected. Forty (91%) products scored a "no-go" according to the OPSS Scorecard and none contained a third-party certification seal on the label. Multiple stimulants were included in products such that the product safety was unknown. Conclusions: The majority of weight-loss dietary supplements analyzed in this case series study had inaccurate labels and were considered a "no-go" according to the Scorecard. Service members should only have access to safe, high-quality dietary supplement products. OPSS is collaborating with the Department of Defense stakeholders to determine the most effective ways for service members to have access to third-party certified products on all military establishments.
