Jan. 10, 2025 -- Over-the-counter protein powders have levels of lead and heavy metals like cadmium that exceed government food safety regulations, according to a report issued by the Clean Label Project, a consumer safety nonprofit.
On average, organic protein powders that were tested showed three times more lead and twice the amount of cadmium than non-organic products, the report said. Chocolate-flavored powders that were tested showed four times more lead than vanilla and up to 110 times more cadmium, the report said.
The EPA says no level of lead is safe for human consumption. Cadmium is a carcinogen and is toxic to the body’s heart, kidneys, gut, brain, respiratory, and reproductive systems.
“This study serves as a wake-up call for consumers, manufacturers, retailers, and regulators alike,” the CLP report said. “With the lack of comprehensive federal regulations specifically addressing heavy metals in dietary supplements, it is critical that the industry independently takes proactive measures.”
On a positive note, the CLP report found lower levels of bisphenols compared to a 2018 study. Bisphenols are hormone disruptors linked to fetal abnormalities and other problems in young children. The study found bisphenols in three of 160 protein powder products, compared to 55% in a previous study.
The report said researchers tested 160 products from 70 top-selling brands, which represents 83% of the market.
An industry association representing supplement manufacturers said the Clean Label Project report didn’t provide sufficient transparency about the criteria used for contamination thresholds, according to CNN.
“Without such clarity, consumers and industry stakeholders cannot fully evaluate the validity of the claims,” Andrea Wong, senior vice president of scientific and regulatory affairs for the Council for Responsible Nutrition, told CNN.
