Supplement Makers Fall Short

by Wellness Letter  

More than half of dietary supplement manufacturers don’t meet Good Manufacturing Practices (GMPs), according to the latest FDA inspection report obtained by the supplement-testing company

Out of 598 supplement manufacturing sites au­­dited in the U.S. (538 total) and abroad (60 in total, including in China, Germany, Brazil, Japan, Korea, Taiwan, and Mexico), 51 percent received letters of noncompliance between Oct. 1, 2018 and Sept. 30, 2019. GMPs cover such practices as establishing and following written protocols for quality control operations; establishing specifications for identity, purity, strength, and composition of the supplements; and having records relating to the production and control of each batch of supplements.

Still, this poor performance is an improvement over past years: The FDA sent noncompliance letters to 70 percent of manufacturers in 2012, for instance, and to 62 percent in 2016.
