Shocking Study: 66% of Popular Protein Powders Contain Unsafe Lead Levels

On Oct 16, 2025

The American Obsession with Protein

It seems there’s never enough protein in our diets these days. Americans have developed a fixation on protein that has evolved into a full-blown wellness trend. From protein-filled pastas to cereals, the market is saturated with products promoting their protein content. Even Starbucks is on board with protein-infused cold foam.

Uncovering Toxic Heavy Metals in High-Protein Products

However, a recent investigation by Consumer Reports published on Oct. 14 unveils a disturbing reality: many protein-rich products are contaminated with toxic heavy metals.

The investigation led by Consumer Reports journalist Paris Martineau involved testing protein powders and shakes, uncovering alarming levels of heavy metals. The results revealed that it’s not just fitness fanatics consuming these products anymore; protein products have become mainstream, and the belief that more protein is always better has become a common misconception.

“We advise against daily use”

Among the 23 most popular protein powders and ready-to-drink shakes tested in the U.S., over two-thirds contained more lead in a single serving than is deemed safe by Consumer Reports’ food safety experts. Some had 10 times that amount. One product, Naked Nutrition’s Vegan Mass Gainer, contained a shocking 7.7 micrograms of lead per serving, marking 1,572% of Consumer Reports’ level of concern. Another top seller, Huel Black Edition, registered 6.3 micrograms of lead or 1,288% of Consumer Reports’ limit.

These concerning levels of contamination are particularly alarming as protein powders are often consumed daily, or multiple times a day. This frequent consumption poses a significant health risk, particularly as contamination has increased, not improved, over the years.

The State of Regulation

Considering the contamination levels, you might think that heavy metals in food would be illegal. However, the protein powder industry operates in a regulatory gray area with limited oversight before products hit the market.

The Food and Drug Administration (FDA) does not approve supplements before they’re sold, and there is no federal limit for how much lead is allowed in a protein powder. Companies are expected to self-regulate, and many don’t disclose any testing at all. This lack of regulation leaves consumers in the dark about what they’re consuming.

Do You Need as Much Protein as You Think?

Contrary to popular belief, you may not need as much protein as you think. According to Harvard Health, the recommended daily amount of protein is just 0.8 grams per kilo of body weight. This level is easily obtainable through whole foods alone.

Despite this, protein has become a branding tool, transforming processed foods into perceived health options. However, the addition of protein does not necessarily make a product healthier. The unglamorous truth is that focusing on eating whole foods is a more effective route to health than relying on protein-infused products.
