A recent study conducted by the Clean Label Project, a national nonprofit dedicated to openness in food and consumer product labeling, has revealed alarming findings about protein powders. The study tested 160 products from 70 top-selling brands and found that 47% exceeded California Proposition 65 safety thresholds for toxic metals like lead and cadmium.
California Proposition 65, officially known as the Safe Drinking Water and Toxic Enforcement Act, is a state law designed to protect residents from harmful chemicals. It requires businesses to provide warnings about notable exposures to substances that can cause cancer, birth defects, or other reproductive harm. Though, it’s critically important to note that these standards are stricter than federal FDA guidelines, which focus on the risk of acute or chronic exposure from specific food sources.
As the study’s lead researcher explains, “The FDA’s levels are based on the risk of acute or chronic lead and cadmium exposure from a particular food source.” In contrast,Proposition 65’s maximum allowable dose levels (MADL) are intended to trigger warnings for consumers about overall exposure to harmful chemicals.This means that a Proposition 65 warning doesn’t necessarily indicate a product is unsafe by federal standards but reflects California’s uniquely stringent approach to chemical exposure notifications.
What Did the Study Reveal?
The Clean Label Project screened all tested protein powders for heavy metals and bisphenols,chemical compounds commonly used in plastics and resins. The results showed varying levels of contaminants, with nearly half of the products surpassing Proposition 65’s safety thresholds.

The research found that 47% of tested products exceeded California Proposition 65 safety thresholds for toxic metals like arsenic, cadmium, lead, and mercury. Shockingly, 21% of the samples contained levels more than twice the allowable limits. The study revealed significant disparities in contamination across different types of protein powders. Organic protein powders, frequently enough marketed as healthier alternatives, showed higher levels of heavy metals, with 79% exceeding Proposition 65 thresholds.These organic options contained three times more lead and twice as much cadmium as non-organic products. Plant-based protein powders also raised red flags, with 77% surpassing Proposition 65 levels for lead. In contrast, only 28% of whey-based powders exceeded these limits. Plant-based options were found to contain three times more lead than their whey-based counterparts. Flavoring played a significant role in contamination levels.A staggering 65% of chocolate-flavored protein powders exceeded Proposition 65 thresholds. These products contained four times more lead and up to 110 times more cadmium than vanilla-flavored options. Researchers noted that whey or collagen-based protein powders without chocolate flavoring had the lowest levels of lead. On a positive note, the study highlighted significant improvements in BPA and BPS levels compared to a similar 2018 study. In 2018, 55% of tested powders were contaminated with these harmful chemicals.This year, only three out of 160 powders tested positive for BPA or BPS, marking a ample betterment. | Category | Findings | For those concerned about heavy metal exposure, opting for non-chocolate-flavored whey or collagen-based protein powders may be a safer choice.

Heavy metals like lead and cadmium are naturally occurring elements, but their presence in food and kitchen products can pose serious health risks. According to California’s Proposition 65 (Prop 65), the Maximum Allowable Dose Level (MADL) for lead is just 0.5 micrograms per day from all sources. For sensitive groups like pregnant women and children, there is no safe level of exposure to lead whatsoever.The FDA’s regulations vary by food type.As an example, canned fruits and vegetables are allowed to contain up to 0.05 parts per million (ppm) of lead, while fruit juices can have up to 50 micrograms per liter.Cadmium, another heavy metal, has an MADL of 4.1 micrograms per day. FDA guidelines permit cadmium levels ranging from 0.1 ppm in leafy vegetables to 2 ppm in shellfish. “High levels of cadmium can cause cancer, kidney disease, and bone problems,” explains Castro. While the human body can slowly excrete small amounts of heavy metals over time, prolonged exposure can lead to significant health issues. Bisphenols,including BPAs and bpss,have been a topic of concern for years. Over a decade ago, the FDA banned BPAs in baby bottles and sippy cups due to their potential health risks.Though, these chemicals are still found in many kitchen products and food packaging. Bisphenols are known for causing health problems in the brain, kidneys, and other organs. Despite the ban, their presence in everyday items like plastic containers and canned goods means exposure remains a risk. | Substance | Prop 65 MADL | FDA Allowable Levels | Health Risks | To minimize exposure to these harmful substances, consider the following steps: While regulations aim to limit exposure, staying informed and making conscious choices can definitely help protect your health.

The link between environmental toxins and cardiovascular disease has become a growing concern in recent years. A 2023 scientific statement by the american Heart Association (AHA) highlights the dangers of low-level exposure to heavy metals like lead, cadmium, and arsenic, which are increasingly associated with heightened risks of heart disease, stroke, and other cardiovascular conditions. “The research on this issue is conflicting and remains an ongoing conversation,” says Bridget Wood, RD, LD, CDCES.“While a 2020 study found that typical supplement use was unlikely to cause harm from heavy metals, the AHA’s findings suggest that even minimal exposure to these metals can have significant health implications.” One of the most striking aspects of these findings is the emphasis on the environmental origins of these metals. “The common thread between these findings? Both emphasize that the presence of these metals is environmental and largely beyond consumer control,” Wood explains. This raises important questions about how individuals can protect themselves in a world where these toxins are pervasive. Recent studies, such as those conducted by the Clean Label Project, have pointed to potential issues with protein powders, which are a staple in many fitness enthusiasts’ diets.However, the lack of specific data has left consumers in the dark. “It’s critically important to note that even though the Clean Label Project study points to problematic issues with protein powder, it does not list the actual lead and cadmium levels that they detected, nor the brands that were tested,” says Castro. “Without that critical piece of information, I can’t tell if the amounts of metals detected are enough to cause human disease,” castro adds. “Regrettably, without full transparency of the actual levels, consumers could be confused and misled instead of gaining confidence and clarity.” While the presence of heavy metals in the environment is largely beyond individual control, there are steps you can take to minimize your exposure. “the safest option would be eating high-protein snacks made from whole foods rather than relying on processed supplements,” suggests Wood. | Key Point | Details | The AHA’s findings underscore the importance of addressing environmental toxins as a public health priority. While individual actions can help mitigate risks, systemic changes are needed to reduce the prevalence of these harmful metals in our environment.For now, staying informed and making mindful dietary choices can go a long way in protecting your heart health. Protein powders have become a staple in many fitness enthusiasts’ diets, offering a convenient way to meet daily protein needs. However, recent concerns about heavy metals and other contaminants in these products have raised questions about their safety. According to experts, while the risk of toxicity from low consumption is minimal, it’s crucial to choose wisely. While protein powders are a popular supplement, some studies have detected trace amounts of heavy metals like lead, arsenic, and cadmium in certain products. Nutritionist Castro emphasizes that the risk of harm is low when consuming protein powder in moderation—such as one protein shake or a single serving size. “It is highly unlikely that you would be impacted by these toxic metals by ingesting low amounts of protein powder,” she says. However, for those who rely heavily on protein supplements, Castro recommends prioritizing protein from whole foods whenever possible. Whole foods not only provide essential nutrients but also eliminate the risk of contaminants found in processed supplements. For consumers concerned about the safety of protein powders, castro suggests opting for unflavored varieties, which often contain fewer additives.
