A recent study has once again highlighted a concerning presence of lead in several popular protein powders, indicating potential health risks. Published on October 16, 2025, the report reiterates findings from an earlier study conducted by the Clean Label Project in January. The research, conducted by Consumer Reports, tested 23 different protein powders and ready-to-drink shakes, revealing troubling levels of toxic metals in many of the products.

Consumer Reports’ study, released on October 14, found that a significant number of tested products contained elevated levels of lead, sparking renewed concerns among consumers and health experts. The report advised against consuming two specific products due to their heavy metal content, highlighting Naked Nutrition’s Mass Gainer powder and Huel’s Black Edition powder. Both companies responded to the findings, with Naked Nutrition emphasizing their commitment to product transparency and customer health.
The study revealed that plant-based products were among the worst offenders for containing elevated lead levels. Consumer Reports’ testing methodology involved purchasing multiple samples of the products over a three-month period, from both online retailers like Amazon and supermarkets such as Whole Foods. While about 70 percent of the products exceeded the organization’s “level of concern” for lead content, some were deemed safe for occasional consumption.
The U.S. Food and Drug Administration (FDA) responded to the findings, stating that they will be reviewing the results from Consumer Reports’ testing. It’s important to note that the FDA has a higher threshold for daily lead consumption compared to California, on which Consumer Reports based their recommendations. Lead exposure, even in small amounts, can pose serious health risks, including immune suppression, reproductive problems, and kidney damage.
Experts like Dr. Rose Goldman and Dr. Pieter Cohen have reiterated the importance of minimizing lead exposure in diets to safeguard against potential health issues. While many of the tested protein products are considered safe for occasional consumption, caution is advised in light of the study’s findings. The grey regulatory area surrounding dietary supplements underscores the need for consumers to stay informed and vigilant about the products they consume.
As the debate around heavy metal contamination in protein powders continues, it’s essential for consumers to be aware of the potential risks associated with these products. Monitoring lead levels in dietary supplements and advocating for stricter quality control measures can help ensure the safety and well-being of individuals who incorporate protein powders into their daily routines. Stay informed and stay safe when choosing your protein supplements.
