The Mary Frances Picciano Dietary Supplement Research Practicum

2017 Agenda

The Office of Dietary Supplements (ODS) at the National Institutes of Health (NIH) offers this intensive practicum to provide fundamental knowledge of dietary supplements to faculty, Ph.D. students, and postdocs at academic institutions; health care practitioners; and other professionals with advanced biomedical degrees. Its three main goals are to:

  1. Provide participants with a thorough overview and grounding about issues, concepts, controversies, and unknowns about dietary supplements and supplement ingredients. A cross-cutting theme will be the importance of scientific investigations to evaluate the safety and efficacy of these products for health promotion and disease prevention and treatment.

  2. Provide participants with information, ideas, and resources to provide instruction about dietary supplements at their academic institutions.

  3. Instill interest among students and investigators attending the practicum to consider undertaking research in the field of dietary supplements.
