The National Institutes of Health (NIH) is offering the Natural Product Early Phase Clinical Trial Award (R33), aimed at funding early-phase clinical trials for promising natural products, including botanicals and dietary supplements. This funding opportunity encourages applications that assess target engagement and the relationship between the intervention and clinical outcomes over a maximum period of three years, with total funding not exceeding $1,050,000. The program emphasizes the importance of rigorous and reproducible trials, particularly in managing conditions such as pain and mental health disorders, while requiring a Plan for Enhancing Diverse Perspectives (PEDP) to ensure inclusivity in research. Interested applicants must submit their proposals by November 14, 2026, and can reach out to NIH Grants Information at grantsinfo@nih.gov for further inquiries.
