Expert Clarifies Lead Concerns in Protein Powders Amidst New Report
A recent report from the Clean Label Project has sparked public concern over the presence of lead and other heavy metals in protein powders, particularly plant-based options. However, a food scientist, who goes by the online handle "hydroxide," has offered a nuanced clarification of these findings, emphasizing the specific regulatory framework used in the study. According to hydroxide, the report's methodology primarily relied on California's Proposition 65 (Prop 65) standards. "It's important to understand that Prop 65 uses very strict limits that are not reflective of federal guidelines," she explained. These standards impose a 1,000-fold safety factor below the level where no harmful effects are observed, making them considerably more stringent than national regulations. This means that products exceeding Prop 65 limits could still be well within federal safety thresholds. Furthermore, hydroxide pointed out that plant-based protein powders tend to have higher concentrations of heavy metals. "Heavy metals are commonly found and naturally found in the soil," she stated, explaining that plants absorb these elements during growth. Therefore, plant-derived ingredients will naturally carry some level of these substances. The expert stressed the importance of consumer awareness regarding testing methodologies and the distinction between various regulatory standards, urging a balanced perspective on product safety claims.
