Toxins Found in Protein Powder: What You Need to Know
For many, protein powder has become a staple in their daily routine, offering a speedy and convenient way to meet their nutritional needs. Whether it’s blended into a piña colada protein smoothie or baked into cosmic brownie protein bites, the versatility of these powders has made them a kitchen essential. Though, a recent study by the Clean Label Project has raised alarming concerns about the safety of these products.The study,which tested 160 products from 70 top-selling protein powder brands,revealed that nearly half of them contained toxic metals. These impurities exceeded the safety limits set by California’s Proposition 65, a regulation designed to protect consumers from harmful chemicals.
Registered dietitian and owner of Compass Nutrition, Adiana Castro, MS, RDN, CDN, emphasizes the importance of protein as a “superpower macronutrient.” She explains, “Our bodies need it to keep us full longer, reduce appetite, and maintain lean muscle, which can lead to weight management.” While protein powders can be a helpful tool, the presence of heavy metals like lead, arsenic, and cadmium poses significant health risks.
The Clean Label Project, a nonprofit dedicated to transparency in food labeling, found that 47% of the tested products contained these harmful substances. This discovery has left many consumers questioning the safety of their favorite powders.

Protein powders have become a staple in many health-conscious diets, offering a convenient way to boost protein intake. However, a recent study by the Clean Label Project has uncovered alarming levels of heavy metal contamination in these popular supplements. The findings, which tested 160 protein powders, revealed that nearly half exceeded California Proposition 65 safety thresholds for toxic metals, raising questions about the safety of these products.
What is California Proposition 65?
California Proposition 65 is a law designed to protect residents from exposure to harmful chemicals.It requires businesses to provide warnings about significant exposures to chemicals that cause cancer, birth defects, or other reproductive harm. Unlike FDA standards, which focus on acute or chronic exposure from specific food sources, Proposition 65’s maximum allowable dose levels (MADL) are intended to trigger consumer warnings about overall chemical exposure.As noted by Castro, “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 MADL, she explains, “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.
Key Findings from the Study
The study screened protein powders for heavy metals like arsenic,cadmium,lead,and mercury,as well as bisphenols (BPA and BPS),chemicals commonly used in plastics and resins. Here’s what the research uncovered:
- 47% of products tested exceeded Proposition 65 safety thresholds for toxic metals.
- 21% of samples contained levels more than twice as high as those allowed under Proposition 65.
Organic Protein Powders: A Surprising Contender
Contrary to popular belief,organic protein powders showed higher levels of contamination. A staggering 79% exceeded Proposition 65 levels for heavy metals, containing three times more lead and twice as much cadmium as their non-organic counterparts.
Plant-Based vs.Whey-Based Powders
Plant-based protein powders also raised concerns, with 77% exceeding Proposition 65 levels for lead. In comparison, only 28% of whey-based powders surpassed these thresholds. Plant-based options contained three times more lead than whey-based products.
The Role of Flavoring
flavoring played a significant role in contamination levels. Chocolate-flavored powders were notably problematic, with 65% exceeding Proposition 65 levels. These products contained four times more lead and up to 110 times more cadmium than vanilla-flavored options.
The Safest Options
Researchers found that whey or collagen-based protein powders that are not chocolate-flavored contained the least amount of lead, making them a safer choice for consumers.
A Silver Lining: BPA and BPS Levels Improve
On a positive note, the study found significant improvements in BPA and BPS contamination levels compared to a similar study conducted in 2018. In 2018, 55% of powders tested were contaminated with BPA or BPS. this year, only three out of 160 powders tested positive for these chemicals—a marked betterment.
What Consumers Need to Know
While the findings are concerning, it’s important to note that proposition 65’s thresholds are stricter than federal standards.Consumers should remain informed about the potential risks and consider opting for whey or collagen-based, non-chocolate-flavored powders to minimize exposure to heavy metals.
| Protein Powder Type | Lead Contamination | Cadmium Contamination |
|——————————-|————————|—————————|
| Organic | 3x higher | 2x higher |
| Plant-Based | 3x higher | N/A |
| Chocolate-Flavored | 4x higher | 110x higher |
| Whey/Collagen (Non-Chocolate) | Least | Least |
Final Thoughts
The Clean Label Project’s study highlights the importance of transparency in the protein powder industry. While improvements in BPA and BPS levels are encouraging, the high levels of heavy metals in certain products underscore the need for stricter quality control. Consumers are encouraged to stay informed, read labels carefully, and choose products that align with their health and safety priorities.

The presence of heavy metals in food has sparked widespread concern among food safety experts and concerned citizens alike. With growing awareness of the potential health risks, understanding the sources and regulations surrounding these contaminants is more critical than ever.
The Risks of Heavy Metals in Food
Heavy metals like lead and cadmium can have severe health implications. “High levels of lead can cause long-term health problems in the brain, kidneys, and other organs,” explains Castro. “high levels of cadmium can cause cancer, kidney disease, and bone problems.” While the human body can slowly excrete small amounts of these metals over time, prolonged exposure poses significant risks, especially for vulnerable groups like pregnant women and children.
Regulatory Standards for Lead and Cadmium
Regulations vary depending on the type of food and the governing body.As an example, California’s Prop 65 MADL (Maximum Allowable Dose Level) for lead is set at 0.5 micrograms per day from all sources. Though, for sensitive populations, there is no safe level of exposure to lead.
The FDA has it’s own guidelines,which differ by food category. For example, canned fruits and vegetables are allowed up to 0.05 parts per million (ppm) of lead, while fruit juices can contain up to 50 micrograms per liter.
When it comes to cadmium, the Prop 65 MADL is 4.1 micrograms per day. FDA regulations permit cadmium levels ranging from 0.1 ppm in leafy vegetables to 2 ppm in shellfish.
sources of Contamination
researchers point to two primary sources of these contaminants: the soil where ingredients are grown and the packaging used for food products. This highlights the need for stricter agricultural and manufacturing practices to minimize exposure.
Key takeaways
To summarize the key points:
| Contaminant | Prop 65 MADL | FDA Allowable Levels |
|——————|——————|————————–|
| Lead | 0.5 µg/day | 0.05 ppm (canned fruits) to 50 µg/L (fruit juices) |
| Cadmium | 4.1 µg/day | 0.1 ppm (leafy veggies) to 2 ppm (shellfish) |
What Can You Do?
While regulatory bodies work to enforce safety standards,consumers can take steps to reduce their exposure. Opt for organic produce when possible, as it may have lower levels of contaminants. Additionally,diversify your diet to avoid over-reliance on foods known to have higher metal concentrations,such as fruit juices and shellfish.

Final Thoughts
The issue of heavy metals in food is complex, but awareness and informed choices can go a long way in protecting your health. Stay vigilant, stay informed, and advocate for stricter safety standards to ensure a healthier future for all.
Is BPA in Your Kitchen Safe? What You Need to Know
Bisphenol A (BPA), a chemical commonly found in food packaging and kitchen products, has been a topic of debate for years. While the FDA maintains that BPA is safe at low levels—specifically, 5 milligrams per kilogram of body weight per day—concerns about its potential health risks persist.
The History of BPA in Consumer Products
BPA, along with its counterpart BPS, was banned from baby bottles and sippy cups over a decade ago due to fears of developmental issues in children. However, these chemicals are still prevalent in many kitchen products and food packaging. Research has linked bisphenols to metabolic problems, cancer, and other health concerns, raising questions about their safety in everyday use.
What Does the FDA Say?
Despite these concerns, the FDA asserts that the low levels of BPA found in some foods are not harmful. The agency has set a safety threshold of 5 milligrams per kilogram of body weight per day, based on extensive research. However, critics argue that even minimal exposure over time could pose risks, especially for vulnerable populations like children and pregnant women.
What Does This Mean for You?
For consumers, the presence of BPA in everyday items can be unsettling. While the FDA’s stance offers some reassurance, many experts recommend taking precautions. Opting for BPA-free products, avoiding plastic containers with recycling codes 3 or 7, and choosing fresh foods over canned ones can help reduce exposure.
Key Takeaways
| Key Point | Details |
|————————————|—————————————————————————–|
| FDA Safety Threshold | 5 mg/kg body weight per day |
| Banned in Baby Products | since 2012, due to developmental risks |
| Common Sources | Food packaging, kitchen products |
| Potential Health Risks | Metabolic problems, cancer |
Final Thoughts
While the FDA continues to monitor BPA’s safety, staying informed and making mindful choices can definitely help you navigate this complex issue.Whether you’re preparing a protein shake at home or storing leftovers, understanding the risks and taking proactive steps can make a difference in your health and well-being.

The common thread between these findings? Both emphasize that the presence of these metals is environmental and largely beyond consumer control.”
but what about what we can control?
It’s important to note that although 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.
“Without that critical piece of information, I can’t tell if the amounts of metals detected are enough to cause human disease,” Castro tells us. “Unluckily, without full transparency of the actual levels consumers could be confused and misled instead of gaining confidence and clarity.”
“The safest option would be eating protein from whole foods,” she says. “However, it is highly unlikely that you would be impacted by these toxic metals by ingesting low amounts of protein powder—like one protein shake or one serving size.”
If you’re concerned,though,Castro recommends unflavored protein powders,looking for products tested by verified third parties such as NSF Certified for Sport or Clean label Project, or even reaching out directly to your favorite brand for transparency about their sourcing, heavy metal levels, and safety practices.
The study also concludes with a list of brands that are Clean Label Project Certified.
