Description
The 2018 study by the Denver-based Clean Label Project used the independent analytical chemistry laboratory Ellipse Analytics to test the animal- and plant-based protein powders. Clean Label selected and purchased the powders from retail store shelves and from online sources. In addition to heavy metals, the research project included testing for BPA, a known endocrine disruptor. Results showed 55 percent of powders tested had measurable levels of BPA. Of the 134 tested powders, 28 contained twice the regulatory limit of 3 micrograms of BPA. One contained more than 25 times the allowed level of BPA in just one serving. The specific products tested in the Clean Label study are ranked the top sellers, according to statistics from Nielsen and the Amazon.com best-seller list. According to the research report released today, of the 134 products tested, 53 were found to have "substantially elevated" levels of the following heavy metals.
