Research Project: Representative Sampling Plans and Pilot Study Planning for Botanical Ingredients for Dsid Studies

Location: Nutrient Data

Project Number: 8040-52000-065-01
Project Type: Specific Cooperative Agreement

Start Date: Sep 01, 2013
End Date: Aug 31, 2014

Objective:
Obtain research information to develop representative sampling plans and plan the scope of pilot and national studies for the analysis of botanical dietary supplements for the Dietary Supplement Ingredient Database (DSID).

Approach:
NDL and Cooperator will 1) Evaluate NHANES 2007-08, NHANES 2009-10 dietary supplement data files, including 24-hr recall information, to identify the frequency of reporting and types of products reported (and trends) for the botanical dietary supplement ingredients of interest; 2) Evaluate other resources, including DSID information, information from other surveys, information from trade associations, store and internet surveys, and the Nutrition Business Journal, to identify patterns, product categories, and channel and brand information; and 3) Identify gaps in information needed to develop representative sampling plans for identified ingredients. NDL will provide leadership, personnel, administrative support, and space to carry out this project.
