Lead Contamination Detected in Most Popular Protein Powders

A Consumer Reports investigation reveals that over two-thirds of popular protein powders and shakes in the U.S. contain unsafe levels of lead, with contamination increasing over time and largely originating from plant-based sources. The lack of federal regulation and reliance on self-regulation by companies exacerbate the issue, and experts advise that most people do not need protein supplements at all, as a balanced diet of whole foods suffices for meeting protein needs.
