For many fitness enthusiasts, protein powder has become a staple supplement.
Marketed as an easy and efficient way to build muscle and support recovery, it’s widely available in supermarkets, gyms, and online stores.
But behind the healthy image, some of these products may pose unexpected health risks.
A recent American study published in Consumer Reports has revealed that several protein powders contain harmful levels of heavy metals such as lead, cadmium, and arsenic.

Lack of regulation leaves consumers exposed
The new findings from Consumer Reports highlight not only the growing contamination problem but also a deeper issue within the supplement industry: a lack of effective regulation.
Unlike pharmaceuticals, protein powders and other dietary supplements are not required to undergo pre-market safety evaluations by the U.S. Food and Drug Administration.
Manufacturers can sell these products without demonstrating their safety or providing proof that heavy metal levels remain within acceptable limits.
Experts warn that this regulatory gap allows contaminated or poorly tested products to reach store shelves unchecked.

According to Pieter Cohen, MD, an associate professor of medicine at Harvard Medical School, many consumers mistakenly believe that supplements are inherently safe simply because they are sold legally.
However, Pieter Cohen stresses that these products can pose significant health risks when consumed regularly, especially when toxic substances like lead accumulate in the body over time.
The most contaminated products
The American test results identified specific products with notably high concentrations of heavy metals. The worst offenders include:
- Naked Nutrition Vegan Mass Gainer, Vanilla
- Huel Black Edition, Chocolate
- Garden of Life Sport Organic Plant-Based Protein, Vanilla
- MuscleMeds Carnivor Mass, Chocolate Peanut Butter
Experts warn that regular consumption of these substances can damage organs and the nervous system, especially with long-term use.
