The National Institutes of Health (NIH) is offering the NCCIH Natural Product Early Phase Clinical Trial Award (R33), aimed at supporting investigator-initiated clinical trials of natural products such as botanicals and dietary supplements. This funding opportunity encourages applications for early phase trials that assess the impact of these products on specific biological targets and their potential clinical outcomes, with a focus on optimizing study designs and dosage. The initiative is crucial for advancing research in complementary and integrative health approaches, ensuring that projects adhere to rigorous scientific standards and include a Plan for Enhancing Diverse Perspectives (PEDP). The total estimated funding for this program is $1,050,000, with applications due by November 13, 2026.
