Several protein powders have been found to contain lead at levels exceeding safety concerns. According to a recent Consumer Reports investigation testing 23 protein powders and shakes, more than two-thirds contained lead at levels higher than the recommended daily limit of about 0.5 micrograms per serving. Notably, some plant-based protein powders had alarmingly high lead levels. The protein powders with the highest lead content to avoid include:

• Naked Nutrition’s Mass Gainer powder (7.7 micrograms per serving, exceeding 1500% of the concern threshold)
• Huel’s Black Edition powder (6.3 micrograms per serving, about 1290% of the limit)

Others with elevated lead levels where consumption should be limited include:

• Garden of Life’s Sport Organic Plant-Based Protein
• Momentous’ 100% Plant Protein
• MuscleMeds’ Carnivor Mass powder (non-plant based but over 200% level of concern)

Additional products containing lead above concern levels include a mix of other plant-based, dairy-based, and beef protein powders. Plant-based powders on average had much higher lead levels—about nine times that of dairy proteins. Chocolate-flavored powders also tend to have higher lead content than vanilla flavors. While not all protein powders contain lead above safe limits, many do pose a potential risk if consumed daily over time, especially since lead accumulates in the body and no level is considered fully safe. Consumers should be cautious with the above-mentioned powders, consider limiting frequency of use, and look for products tested and certified with lower heavy metal contamination. Choosing powders with non-detectable or minimal lead levels, such as Muscle Tech 100% Mass Gainer (lead not detected), is advisable for regular consumption. Awareness of heavy metal contamination in protein supplements is important for long-term health.
