Comparison of Label Claims Measured Curcuminoid Content and Dosage Form Performance Quality With Industry Standards for Turmeric Dietary Supplements

摘要

Turmeric (Curcuma longa) is a popular ingredient in dietary supplements (DS), promoted for a variety of health effects. FDA label regulations require information on the total weight of each botanical or extract present in a botanical DS, unless it is part of a proprietary blend. Information on the concentration of phytochemicals in extracts is voluntary. DS with turmeric rhizome powders and/or extracts were tested for curcuminoid content and the results compared to label claims and industry standards as part of the Dietary Supplement Ingredient Database (DSID) research program. The performance quality of the dosage forms was also evaluated.
