A recent investigation indicates that **over-the-counter protein powders** may contain **high levels of lead and cadmium**, particularly in **plant-based, organic, and chocolate-flavored** varieties.
The **US Environmental Protection Agency** states that there is no safe threshold for lead, while cadmium is recognized as a **carcinogen** affecting multiple bodily systems.
**Organic protein powders** had an average of **three times more lead** and **twice the cadmium** compared to their non-organic counterparts, with plant-based powders exhibiting even higher levels.
**Chocolate-flavored protein powders** showed particularly concerning contamination, containing **four times more lead** and significant amounts of cadmium compared to vanilla versions.
The **Clean Label Project** urges consumers to shop wisely, suggesting **pea-based powders** as the lowest in heavy metals and recommending inquiries to brands about contaminant levels.
