Organic Protein Powders likely to contain metals compared to non-organic products.
Healthy eating enthusiasts may want to reconsider their protein powder choices. A new study shows 40 percent of 134 brands tested have elevated levels of heavy metals. Perhaps shockingly Certified Organic products were twice as likely to contain heavy metals as the non-organic powders.
ORGANIC PROTEIN POWDERS| CONTAIN METALS
The 2018 study by the Clean Label Project used the independent analytical chemistry laboratory Ellipse Analytics to test the animal and plant-based protein powders. Clean Label also selected and purchased the powders from retail store shelves and 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.
ORGANIC PROTEIN POWDERS | TOP SELLERS SELECTED
The specific products tested in the Clean Label study are ranked the top sellers. This 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.
ORGANIC PROTEIN POWDERS| HIGH LEVEL OF HEAVY METALS
The finding showed the products Certified Organic by the USDA were twice as likely to contain high levels of heavy metals when compared to non-organic protein powders. Interestingly the study found other surprising statistics about plant-based protein powders.
- 75 percent had measurable levels of lead.
- Each contained on average twice the amount of lead per serving as other products.
- In addition to the lead, the plant powders in several cases contained mercury, cadmium and arsenic above health-based guidelines.
Clean Label Project Director Jackie Bowen said the toxins found in the plant products could put vegetarian diets at heightened risk of health issues. If, they are regularly consuming the plant-based powders. The powders had on average twice the amount of lead per serving of other products.
The director of operations and quality at the testing laboratory Ellipse Analytics said there could be several explanations as to why the powders have excessive levels of heavy metals.
“Plant-based protein powders have higher levels of heavy metals than non-plant-based protein powders,” said Sean Callan, the Ellipse Analytics scientist.
ORGANIC PROTEIN POWDERS| PLANT LOCATION SUSPECT
“This could be due to the locations where the protein powder manufacturers’ plant ingredients are sourced having contaminated soil. This is especially true in the United States where there may be a higher incidence of heavy metals in the soil of some regions.”
Testing further revealed that about 10 percent of whey-based protein powders contained lead levels above health guidelines.
There was some good news coming out of the research. There was a finding that no egg-based protein powders tested contained lead.
The study data was analyzed by Clean Label Project’s Technical Advisory Board of statisticians, epidemiologists, food safety scientists and registered dietitians before being published. The study process is being peer-reviewed.
Study results on the nonprofit’s website are presented in a five-star rating system. Study results name each product tested and shows how contaminated it is compared to other products in the same study. More than 40 of the products tested only received one star.
