Texas Attorney General Launches Investigation into Protein Powder Contaminants

The Texas Attorney General, Ken Paxton, has initiated an extensive investigation into protein powder manufacturers. This move follows troubling reports highlighting the presence of heavy metals in popular protein powders and instant shakes.

About 15 years ago, Consumer Reports conducted a study that examined 15 different protein drinks. It discovered that all samples contained at least one type of contaminant, including arsenic, cadmium, lead, and mercury.

According to AG Paxton, “Too many companies sneak harmful ingredients into their products.”

Researchers found that while many beverages had low to moderate levels of heavy metals, some had concentrations that could be concerning if consumed regularly. A recent Consumer Reports test analyzed 23 popular brands and revealed that the issues, which were once rare, have become more prevalent—and even more severe.

In fact, over two-thirds of the analyzed products had lead levels exceeding what experts consider safe for daily consumption. Some products contained lead concentrations more than ten times higher than recommended safety levels.

Lead exposure is a known health risk. Although the safe exposure level for adults remains unclear, it can lead to various health issues, including diminished kidney function, heart concerns, infertility, and weakened joints.

Further findings from the FDA indicated that the most alarming effects of lead exposure occur during critical periods of brain development. Infants and young children who are exposed to high levels of lead may face neurological issues, learning disabilities, and reduced IQ.

A recent study by Consumer Reports, led by chemist Tunde Akinleye, found that average lead levels in protein powders were noticeably higher than in past studies, and fewer products had undetectable lead amounts.

Shockingly, one product, Naked Nutrition’s vegan mass gainer powder, contained twice the lead concentration of the worst product reported back in 2010, with 7.7 micrograms of lead per serving—about 1,570% of the safety threshold. Similarly, Huel’s Black Edition powder raised concerns with 6.3 micrograms of lead per 90 grams, which is around 1,288% of the acceptable daily limit.

Other products, like Garden of Life’s Sports Organic Plant-Based Protein, were also flagged for high lead content. The report concluded the following:

• About 70% of the analyzed products contained levels of lead exceeding 120% of the safety limit.
• Three products were found to exceed safety levels for inorganic arsenic and cadmium, with Huel’s Black Edition containing more than double the harmful levels of cadmium.
• There are recommendations to limit consumption of Naked Nutrition’s Vegan Mass Gainer and Huel’s Black Edition, and only consume Garden of Life products once a week.
• Plant-based protein powders generally had lead levels nine times higher than those made with milk proteins and twice as high as beef-based products.

James Clark, CMO of Naked Nutrition, emphasized that the company prioritizes customer health and claims to source materials from suppliers who provide heavy metal testing documentation. Meanwhile, a spokesperson from Huel defended the product’s formulation and safety, mentioning rigorous testing processes.

Momentus indicated that they had revamped their product lineup, discontinuing those tested by Consumer Reports, while Garden of Life asserted that their products meet heavy metal safety standards as per FDA and EPA guidelines.

The Clean Label Project also reported that heavy metals are a widespread concern among protein powders, with nearly half of top-selling products exceeding safety limits.

“Protein is a key nutrient for health, and Texans deserve access to clean protein powders without contamination worries,” Paxton stated, reiterating his commitment to public health. He expressed resolve to take action against any companies that misrepresent their product safety regarding heavy metal contamination.
