Tag: Protein contamination

An estimated 25-50% of all proteins in living organisms require metal ions to carry out their essential functions. The question, "What metal has protein?" stems from a fundamental misunderstanding, as metals are inorganic elements and proteins are complex biomolecules; however, their biological partnership forms a critical class of substances called metalloproteins.

According to a Clean Label Project study, almost half of the top-selling protein powders tested contained detectable levels of heavy metals and other contaminants. Knowing whether your bulk protein powder is 3rd party tested is crucial for ensuring the safety and quality of the product you consume regularly.
