A new investigation by Consumer Reports (CR) has raised serious concerns about the safety of whey protein powders and other popular supplements. The study, released on 14 October 2025, found that most tested products contained unsafe levels of lead and other toxic metals.
Led by Tunde Akinleye, a chemist and food safety researcher at CR, the report revealed that over two-thirds of 23 protein products tested had more lead per serving than what experts consider safe.
