Dietary Supplement Laboratory Quality Assurance Program: Exercise K Final Report



Melissa M. Phillips, Catherine A. Rimmer, Laura J. Wood


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 for demonstration of compliance with various regulations including the dietary supplement current good manufacturing practices (cGMPs). Exercise K of this program offered the opportunity for laboratories to assess their in-house measurements of nutritional elements (P and Fe), contaminants (mercury and acrylamide), water-soluble vitamins (vitamins B1, B2, and B3), fat-soluble vitamins (vitamin K1), and phytosterols in foods and/or botanical dietary supplement ingredients and finished products.
