-Plant-based powders had three times more lead than products based on whey.
- Organic powders had three times more lead and twice as much cadmium as non-organic powders.
- Chocolate-flavored powders had four times more lead and up to 110 times more cadmium than vanilla-flavored powders.
These findings are concerning, as heavy metal exposure can lead to serious health issues, including cancer, neurotoxicity, and reproductive problems ².
However, it's essential to note that not all protein powders are created equal. Some products, like those made from peas, seem to have lower levels of heavy metals ¹.
- Choose products from reputable manufacturers that prioritize quality and safety.
- Opt for products made from whey or eggs, which tend to have lower levels of heavy metals.
- Avoid plant-based and organic products, unless you can verify their safety through third-party testing.
-
Contact manufacturers and ask about their testing practices and heavy metal levels in their products.
