The National Institute of Standards and Technology (NIST) has established a Dietary Supplement Quality Assurance Program (DSQAP) in collaboration with the National Institutes of Health (NIH) Office of Dietary Supplements (ODS). Program participants measure concentrations of active and/or marker compounds as well as nutritional and toxic elements in food and dietary supplement samples distributed by NIST. Data are compiled at NIST where they are analyzed for accuracy, precision, and concordance within the community. Reports and certificates of completion are sent to participants, which can be used to demonstrate compliance with current Good Manufacturing Processes (cGMPs) as determined by Food and Drug Administration (FDA). The DSQAP has conducted five exercises to date, with total participation including over 75 individual laboratories and many more analysts.
