Nearly half of the protein powders tested contain toxic heavy metals (lead, cadmium) that can harm brain, heart, and kidney health.

This claim is based on independent reports, notably that of the 'Clean Label Project' (2018), which did indeed detect traces of heavy metals in many sports nutrition products (observational study). It is scientifically accurate that these metals are present in the environment and can accumulate in plant-based ingredients, which warrants vigilance. However, the actual health risk depends on dosage: most of the products tested show levels well below the acute toxicity thresholds set by health agencies for the general population. The notion that normal consumption systematically causes organ damage is therefore an exaggerated extrapolation of the risk. It is preferable to favor brands that conduct rigorous third-party testing to minimize cumulative exposure. In short, the presence of metals is documented, but the immediate danger is often overestimated in wellness discourse.
