Melissa M. Phillips, Catherine A. Rimmer, Laura J. Wood, Anthony F. Marlow, Michele M. Schantz, John R. Sieber


The NIST Dietary Supplement Laboratory Quality Assurance Program (DSQAP) was established in collaboration with the National Institutes of Health (NIH) Office of Dietary Supplements (ODS) in 2007 to enable members of the dietary supplements community to improve the accuracy of measurements made in compliance with various regulations. Exercise H of this program offered the opportunity for laboratories to assess their in-house measurements of nutritional elements (Ca, Cu, and Mn), contaminants (polycyclic aromatic hydrocarbons, PAHs), water-soluble vitamins (choline), fat-soluble vitamins (tocopherols), fatty acids, and phytosterols in foods and/or botanical dietary supplement ingredients and finished products.
