Protein Powders: What You Need to Know Now
Health Points
- Recent tests show many popular protein powders contain potentially harmful levels of lead.
- Plant-based protein powders had the highest lead contamination, some over 1,000% of safety guidelines.
- Experts stress there is no truly safe level of lead exposure, especially for children and frequent users.
Protein powders and shakes are a common choice for those wanting more protein in their diets, but a Consumer Reports investigation reveals many products contain risky amounts of lead. Testing across 23 protein supplements highlighted widespread contamination, particularly in plant-based options.
Some plant-based powders contained lead at levels far above recommended safety thresholds, while dairy-based powders generally had lower, but still concerning, amounts. Vanilla flavors tended to have lesser contamination than chocolate, and three products also exceeded safe levels for other heavy metals like cadmium and arsenic.
“That’s a serious concern, because the lead can stay in the body for months or longer,” says Dr. Pieter Cohen, a Harvard Medical School supplement expert.
There is no known safe level for lead exposure, according to public health authorities. For adults, long-term lead intake may increase the risk of kidney problems, high blood pressure, and reduced cognitive function, while children face additional risks due to vulnerability during brain development.
Separate studies also flagged additional protein powders for unsafe levels of heavy metals, and currently, the FDA doesn’t test or regulate these supplements before they hit the market. This means it’s up to consumers to make informed choices about their protein supplement intake.
Consumer Reports recommends completely avoiding certain brands, such as Naked Nutrition Vegan Mass Gainer and Huel Black Edition, while some products may be used occasionally or just once per week. Several whey and plant-based options fell below the organization’s safety concerns and may be better daily choices.
Before adding any supplement, check independent test results and consider natural food sources of protein. If you or your family use protein powders frequently, talk with your healthcare provider about safer options.
