Protein Powder Contamination: 47% of Brands Tested Showed High Lead and Cadmium Levels
A Clean Label Project investigation revealed that many over-the-counter protein powders contain concerning levels of lead and cadmium, exceeding California’s Proposition 65 safety limits in 47% of samples. Plant-based, organic, and chocolate-flavored powders showed the highest contamination, with organic products containing three times more lead and twice the cadmium compared to non-organic options. These heavy metals are absorbed by plants from contaminated soil, and chocolate flavoring significantly increased contamination levels. While BPA levels have decreased since a 2018 study, consumers are advised to choose whey or egg-based vanilla protein powders for lower heavy metal content.
