Nutritional Supplement Research: Beyond the Status Quo

Background What is the Status Quo? Common Problems and Solutions –Quality control –Dosing Overview

Background Dietary Supplement Health and Education Act of 1994 (DSHEA) DSHEA deregulation No GMP’s No quality control standards No requirement to show safety or efficacy The Office of Dietary Supplements (ODS) was established through DSHEA (by NIH in 1995) and collaborates with the National Center for CAM (NCCAM) ODS and NCCAM promote and award funding for scientific research on dietary supplements Nesheim, Pub Health Nutr,

What is the ‘Status Quo?’ Source of Supplement?:Usually off-the-shelf Verification of quality?:Usually not Dose?:Usually what others have used Kinetics/bioavailability?:Usually not Study design?:Usually good! Data analysis?:Conventional and sound Data display & interpretation?:Usually marginal or poor Reality?

Quality Control (Problem - Dissolution) > 50% of calcium supplements and many single and multivitamin-mineral preparations fail to meet USP disintegration and dissolution standards. > 40% of melatonin supplements fail to meet USP disintegration standards.

Good Manufacturing Practices (GMP) provide a system of processes, procedures, and documentation to assure a product has the identity, strength, composition, quality, and purity that it claims. Three independent non- governmental programs provide GMP guidelines for dietary supplements. Adoption is VOLUNTARY Natural Products Association (NPA GMP) NSF GMP USP Dietary Supplement Verification Program Quality Control (Solution)

Quality Control A word about mixtures (cocktails) or “Product Testing” Effects (or lack of effects) observed using multiple ingredients violates basic scientific philosophy. There is no way to know if the ingredients (or which ingredients) are acting synergistically, antagonistically, or if they are biologically active at all. > 100 interactions possible between ingredient pairs; > than 1,000,000 interactions possible among random groupings SuperStuff x stronger than our 1000 formula!
