This legislation mandates the Secretary of Defense to establish and maintain comprehensive lists of dietary supplement ingredients and performance-enhancing substances that are prohibited for use by members of the Armed Forces. These lists must be updated at least every 90 days and made publicly accessible through various formats, including a viewable internet website, a searchable database, and a downloadable digital file, to ensure ease of access for service members and vendors. A key provision introduces a "good faith standard" that allows commanding officers to elect not to discipline a service member for possessing or using a prohibited dietary supplement ingredient, provided it is not a controlled substance. This discretion applies if it is the member's first disciplinary offense, they meet the good faith standard, and they agree to participate in education, counseling, or drug testing in lieu of discipline. The bill clarifies that such possession, when meeting the good faith standard, does not constitute drug abuse. The good faith standard is met if a member lacked actual knowledge of the prohibited ingredient, purchased the supplement from a Department of Defense-affiliated retail facility, reasonably relied on a search that failed to identify the ingredient, or otherwise demonstrated a reasonable belief that the supplement was safe. This aims to protect members who inadvertently consume prohibited substances. Furthermore, the bill requires the Secretary of Defense to revise Department of Defense Instruction 6130.06 and enhance the Operation Supplement Safety internet website within one year. Website improvements include advanced search tools with autofill and autocorrect, artificial intelligence for scanning product labels, and a notification system for new prohibited ingredients. The Secretary must also review opportunities to incorporate dietary supplement safety education into existing military training programs. Finally, the legislation mandates several reports to Congress, including an initial report on preventing the sale of prohibited products at DoD-affiliated retail facilities, a final implementation report, and annual reports for five years. These annual reports will detail administrative separation actions related to prohibited supplements, the number of commanding officers who exercised their discretion not to discipline, and an assessment of the effectiveness of dietary supplement safety education efforts.
