Research Project: Dietary Supplement Ingredient Database

Location: Nutrient Data Laboratory

Project Number: 8040-52000-065-02-I
Project Type: Interagency Reimbursable Agreement

Start Date: Aug 21, 2013
End Date: Aug 31, 2014

The Nutrient Data Laboratory (NDL) will provide scientific and technical expertise for acquisition, evaluation, and compilation of analytical ingredient data for dietary supplements. NDL will develop and implement appropriate sampling strategies, define and direct the analytical program, and statistically evaluate the data received. Resulting data will be disseminated at regular intervals through electronic media. NDL will provide leadership, personnel, administrative support, and space to carry out this program.

NDL will continue to expand and improve the Dietary Supplement Ingredient Database (DSID) by adding information about omega-3 fatty acids and prenatal multivitamins. Data will be obtained through USDA-directed contracts with commercial labs and collaborative agreements with universities and other government labs. Commercial labs will be selected in a competitive process according to their use of valid methods and quality control procedures for individual ingredients in dietary supplement matrices. Efforts will continue to optimize methods of data dissemination in keeping with rapidly changing computer and internet technology.
