MANCHESTER, N.H. —
Last year, Consumer Reports tested dozens of popular protein powders and ready-to-drink shakes and found more than two-thirds contained concerning levels of lead.
The investigation raised questions for millions of people who use these products daily.
“Our previous protein powder investigation prompted a crazy wave of reactions and concerns from readers,” said Paris Martineau of Consumer Reports. “One of the most common responses we got was questions from readers asking, ‘What about all the other protein powders out there?'”
Since then, researchers have tested more popular brands, including five reader-requested chocolate protein powders from Clean Simple Eats, Equate, Premier Protein, Ritual and Truvani.
All five powders tested showed low levels of lead. According to Consumer Reports’ threshold, the products are considered safe for daily or near-daily consumption.

On average, the powders also had lower levels of lead and arsenic than products tested last fall.
However, the findings also raised questions about why many other protein powders still contain higher levels of heavy metals.
“There are no federal limits for lead in protein powder. And while the FDA requires that manufacturers keep their products free of harmful contaminants, it is largely up to the companies themselves to determine what counts as harmful and to determine how often to test,” Martineau said.
Nutritionists said most people don’t need protein supplements. Foods such as beans, tofu, eggs, dairy, fish and lean meats can meet daily protein needs.
For those who rely on powders, Consumer Reports says not to assume “healthy” means risk-free. Experts advise being cautious and considering protein powders for occasional use rather than daily consumption.
