OPSS’s mission is to provide the best evidence-based information about dietary supplements to Service Members, their families, healthcare providers, and leaders to achieve human performance optimization.

Our goal is to provide the tools and resources to help users make informed decisions about dietary supplements to optimize their health, performance, and careers.
