A new report by the Clean Label Project has revealed that protein powders may contain toxic metals like lead and cadmium. The non-profit organization tested 160 products from 70 top-selling brands, representing 83% of the market, and found that 47% exceeded one or more state or federal safety thresholds for heavy metals.
The report showed that organic products had three times more lead and twice as much cadmium as non-organic products. Plant-based protein powders contained three times more lead than whey-based alternatives, while chocolate-flavored powders had four times more lead than vanilla options.
Experts warn that the lack of comprehensive federal regulations on heavy metals in dietary supplements means that manufacturers must take proactive measures. However, some experts are cautioning against instant panic and emphasize the importance of considering background exposures and established health standards when evaluating risks.
The U.S. Food and Drug Administration notes that there is no known safe level of lead exposure, which can cause learning disabilities, behavior problems, and lowered IQ in children, as well as kidney dysfunction, hypertension, and neurocognitive issues in adults. Cadmium exposure has a low threshold, with ingestion potentially causing stomach upset, nausea, and vomiting.
The Clean Label Project did not provide detailed information on the report’s methodology, which has led to concerns about its accuracy. Some experts have criticized the project for lacking “critical context” and risking mislead consumers.
To minimize risk, consumers can opt for products certified by reputable organizations like Clean Label or choose whole foods as a primary source of protein.
