Understanding the Heavy Metal Problem in Protein Powders
The presence of heavy metals in protein powders is a well-documented issue stemming from the natural environment. Ingredients like plant-based proteins, which are derived from crops grown in soil, can absorb contaminants from the ground. While the FDA does not routinely test supplements before they are sold, manufacturers are responsible for ensuring their products' safety. This has led to inconsistent safety standards across the supplement industry, leaving consumers to navigate confusing information.
Past Allegations and Lawsuits Against OWYN
In early 2020, OWYN (Only What You Need, Inc.) faced legal action over alleged heavy metal contamination. The Environmental Research Center (ERC) filed two notices of violation against the company, citing Proposition 65, a California law requiring warnings for products containing chemicals known to cause cancer or reproductive harm. The ERC's notices alleged that certain OWYN products contained lead and, in some cases, cadmium, at levels requiring a Proposition 65 warning. These products included specific protein powders and ready-to-drink shakes. Subsequently, a class-action lawsuit was filed, claiming that OWYN's health representations were misleading given the alleged heavy metal content. According to the lawsuit, consumers would have paid less or not purchased the products at all if they had known about the presence of lead. The specific products named in the ERC's notices included: OWYN Chocolate Chip Cookie Dough 100% Plant-Based Bar, OWYN Plant-Based Drink Dark Chocolate, and OWYN Plant-Based Drink Cookies n' Cream.
The Latest Consumer Reports Findings (October 2025)
A recent investigation by Consumer Reports (CR), published in October 2025, put the heavy metal issue back in the spotlight. The report tested numerous protein powders and shakes, finding that many contained lead, often exceeding CR's maximum recommended daily intake. While the report is concerning for the industry as a whole, it provided specific details regarding several brands, including OWYN.
How OWYN Compares to Competitors on Lead Content
The CR report evaluated various protein products, offering a comparative perspective on heavy metal levels. The findings suggest that while OWYN products contain detectable lead, they may pose less of a risk than other brands when consumed moderately. It is important to note that CR's safety levels are stricter than many federal standards, and moderate consumption might be safe for some users.
| Product | CR's Daily Consumption Limit | Lead Amount Relative to CR Limit (per serving) |
|---|---|---|
| OWYN Pro Elite High Protein Shake | 1 serving | ~0.9 times |
| Optimum Nutrition Gold Standard 100% Whey | 1 serving | ~0.5 times |
| Transparent Labs Mass Gainer | 1 serving | ~0.9 times |
| BSN Syntha-6 Protein Powder | 2 servings | ~0.5 times |

OWYN's Stance and Testing Protocols
In response to consumer concerns and past allegations, OWYN has emphasized its commitment to product safety. The company claims to perform robust testing protocols, including third-party testing on every lot of finished products. Their testing process aims to ensure compliance with California's Proposition 65 criteria, which are among the strictest in the world. OWYN maintains that its products are safe for daily use and consistently adhere to its own stringent standards and established government food safety guidance. They also test for the top nine major allergens to prevent cross-contamination and ensure product purity. The company attributes trace amounts of heavy metals to their natural occurrence in agricultural ingredients, such as plant proteins. This transparency is a key part of their strategy to reassure customers about their product quality.
How to Minimize Risk and Stay Informed
For consumers seeking to minimize exposure to heavy metals from supplements, several strategies can be employed. The most effective method is to diversify protein sources, relying on whole foods like lean meats, eggs, and legumes rather than supplements alone. When supplements are necessary, look for brands that voluntarily participate in third-party verification programs like NSF International or Informed Sport, which test for contaminants and banned substances. Checking for specific batch-testing information can also provide peace of mind. It is important to read labels, check recent test results from reputable sources like Consumer Reports, and consider a healthcare professional's advice regarding long-term supplement use, particularly if consuming multiple supplements daily.
The Importance of Independent Testing
Independent, third-party testing is crucial for ensuring the safety and accuracy of dietary supplements, as the FDA does not pre-approve them. This process provides an unbiased verification that a product meets its label claims and is free from harmful contaminants like heavy metals. OWYN states it uses accredited third-party labs for testing, which helps build trust with consumers, though specifics about which labs are not always disclosed. This lack of transparency has been a point of concern for some reviewers. Comparing OWYN's stated testing practices with other brands is difficult without consistent public reporting across the industry.
Conclusion
The question of whether there is still lead in OWYN products is complex. While past lawsuits and recent Consumer Reports findings confirm the presence of detectable lead, the amounts are often below federal and international safety thresholds for occasional consumption. OWYN has publicly stated it conducts third-party testing to ensure compliance with strict standards, including California's Proposition 65, and that its products are safe for daily use. However, some recent reports still recommend cautious consumption, especially for products like the Pro Elite shakes. Consumers should weigh their personal risk tolerance and consider diversifying their protein sources to limit reliance on supplements. Checking the latest product reviews and testing information is also a prudent step for staying informed.
