Case Info
Protein Powder Lead Contamination Lawsuit
On October 14, 2025, Consumer Reports published an independent laboratory analysis revealing that numerous popular protein powder and shake products contain levels of lead that exceed California’s strict safety standards for daily consumption. The testing found that more than two-thirds of the 23 protein supplements analyzed contained lead levels high enough to raise serious health concerns with regular use.
These findings suggest that manufacturers failed to adequately monitor their supply chains and ensure product safety, potentially violating consumer protection laws and breaching implied warranties of merchantability.
If you purchased protein powder products that were later found to contain undisclosed lead contamination, you may be entitled to compensation.
Undisclosed Lead in Popular Protein Supplements
Consumer Reports’ independent testing identified several widely sold protein powder products with concerning lead levels. The organization flagged products containing more than 0.5 micrograms of lead per serving, based on California’s strict standard for daily lead consumption.
The following products showed particularly elevated lead levels:
- Naked Nutrition Vegan Mass Gainer – 7.7 micrograms of lead per serving (highest level found)
- Huel Black Edition powder – 6.3 micrograms per serving
- Garden of Life Sport Organic Plant-Based Protein – elevated lead levels (between 400 and 600 percent of Consumer Reports’ level of concern)
- Momentous 100% Plant Protein – elevated lead levels (between 400 and 600 percent of Consumer Reports’ level of concern)
These contamination levels were discovered through independent laboratory testing, not disclosed by the manufacturers on product labels or marketing materials. Plant-based protein supplements showed consistently higher lead content than dairy or meat-derived products, suggesting contamination in the agricultural supply chain or manufacturing processes.
Dangers of Lead Consumption
Lead is a highly toxic heavy metal with no known safe level of consumption. The metal accumulates in the body over time and can cause serious long-term health effects, including neurological damage, developmental delays in children, and complications during pregnancy.
The FDA has acknowledged that more than 2.2 micrograms per day in children and 8.8 micrograms per day in women of childbearing age may cause health concerns, though experts emphasize that any lead exposure carries risk.
Consumer Protection and Financial Recovery
Consumers who purchased these protein powder products relied on the manufacturers’ implied representations that the products were safe, pure, and suitable for daily consumption.
The discovery of undisclosed lead contamination suggests these companies:
- Failed to adequately test and monitor their products for heavy metal contamination
- Did not maintain proper quality control over their supply chains
- Marketed products as healthy and safe despite containing toxic substances
- Violated implied warranties that the products were merchantable and fit for consumption
If you purchased Naked Nutrition Vegan Mass Gainer, Huel Black Edition, Garden of Life Sport Organic Plant-Based Protein, Momentous 100% Plant Protein, or other protein supplements that were found to contain undisclosed lead contamination, you may be eligible for compensation.
