[I]n addition to the average level of lead being higher than what we found 15 years ago, there were also fewer products with undetectable amounts of it. The outliers also packed a heavier punch. Naked Nutrition’s Vegan Mass Gainer powder, the product with the highest lead levels, had nearly twice as much lead per serving as the worst product we analyzed in 2010. Nearly all the plant-based products CR tested had elevated lead levels, but some were particularly concerning. Two had so much lead that CR’s experts caution against using them at all… Dairy-based protein powders and shakes generally had the lowest amounts of lead, but half of the products we tested still had high enough levels of contamination that CR’s experts advise against daily use…
Unlike prescription and over-the-counter drugs, the Food and Drug Administration doesn’t review, approve, or test supplements like protein powders before they are sold. Federal regulations also don’t generally require supplement makers to prove their products are safe, and there are no federal limits for the amount of heavy metals they can contain.
The article acknowledges that “Many of these powders are fine to have occasionally, and even those with the highest lead levels are far below the concentration needed to cause immediate harm. That said, because most people don’t actually need protein supplements — nutrition experts say the average American already gets plenty — it makes sense to ask whether these products are worth the added exposure.”
