Dietary Supplement Laboratory Quality Assurance Program: Exercise J Final Report



Laura J. Wood, Melissa M. Phillips, Catherine A. Rimmer, Mary Bedner, Kaitlyn Chieh, Rick L. Paul


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 J of this program offered the opportunity for laboratories to assess their in-house measurements of nutritional elements (Ca, Mg, and Zn), contaminants (arsenic and aflatoxins), water-soluble vitamins (vitamins B5 and B6), fat-soluble vitamins (vitamin E), fatty acids, isoflavones, and botanical authenticity/identification in foods and/or botanical dietary supplement ingredients and finished products.
