Some protein powders contain cancer-causing toxins, new study shows

January 13, 2025 - from Yahoo Life:

"A new report by the Clean Label Project has found that protein powders may contain something other than muscle-building nutrients: lead and cadmium, both of which are toxic.

"The report tested 160 products from 70 of the top-selling protein powder brands representing 83% of the market. Of the products tested, 47% exceeded one state or federal regulatory rule for safety, including California’s strict Proposition 65 safety thresholds for toxic metals.

"Among those with the highest levels of heavy metal contamination on average, interestingly, were the organic products—which showed three times more lead and twice the amount of cadmium compared to non-organic products.

"Plant-based protein powders also did not fare well, showing three times more lead than whey-based alternatives—while chocolate-flavored powders contained four times more lead than vanilla, aligning with other recent findings of heavy metals being present in cocoa-containing products."
