A Client Studies examine analyzing 23 protein powders and shakes indicated that, in response to the model’s personal security specialists, over two-thirds contained lead ranges deemed unsafe in a single serving, with some exceeding advisable every day limits considerably.
Moreover, a report conducted from 2024 to 2025 by the Clear Venture Label from 2024-2025 examined 160 protein powders, discovering that 7% surpassed California Proposition 65 thresholds for poisonous metals.

The report on heavy metals in protein powders
Understanding which research and experiences to belief might be tough.

Clara Nosek, a registered dietitian, factors out that the Clear Label Venture didn’t disclose its methodology or a hazard quotient, which tells you the way a lot of the contaminant was used to evaluate the potential well being dangers related to its publicity. “The shortage of methodology means their findings can’t be reproduced, which does ship up crimson flags from a scientific strategies perspective,” Nosek warns.
