Is there lead in Owyn protein shakes? An in-depth product safety investigation

4 min read

According to an October 2025 investigation by Consumer Reports, many popular protein products, including Owyn's Pro Elite shake, contain detectable levels of lead. These recent findings echo previous concerns, leaving many consumers to question, 'Is there lead in Owyn protein shakes?' and to better understand the risks associated with certain supplements.

Quick Summary

Detectible lead levels have been found in Owyn products according to both recent Consumer Reports investigations and past Proposition 65 violation notices. Owyn states its products are safe and tested for allergens, but transparency regarding specific heavy metal testing remains a consumer concern, especially for plant-based supplements.

Key Points

  • Recent Findings: A 2025 Consumer Reports investigation found detectable lead levels in Owyn's Pro Elite protein shake, though within a one-serving per day limit set by CR.

  • Past Allegations: In 2020, Owyn received Proposition 65 violation notices for lead and cadmium in multiple products, leading to lawsuits.

  • Plant-Based Risks: Heavy metals are a common issue for many plant-based proteins, as plants absorb them from the soil, making them more susceptible to contamination.

  • Third-Party Testing: Owyn conducts third-party testing, but primarily focuses on allergens publicly. Full heavy metal test results and accrediting lab details are not always transparently shared.

  • Consumer Advice: Experts recommend balancing supplement use with whole foods and suggest choosing brands with comprehensive third-party certifications (like NSF) that test for heavy metals.

  • Batch Verification: Older products may have higher contamination risks. Check production dates and be aware that products on shelves may be from older batches.

Recent Consumer Reports Findings on Owyn and Lead

In a recent 2025 investigation, Consumer Reports (CR) tested 23 popular protein products and found concerning levels of lead and other heavy metals in many of them. The report specifically highlighted Owyn's Pro Elite High Protein Shake, which was found to have lead levels that, while below some federal limits, were 88% of CR's daily 'level of concern' per serving. As a result, CR recommended a limit of one serving per day for this particular product. This investigation reaffirmed long-standing concerns about heavy metals in supplements and the need for greater transparency from manufacturers.

Prior Legal Challenges and Product Violations

The issue of lead in Owyn's products is not new. In 2020, the Environmental Research Center (ERC) filed a Notice of Violation under California's Proposition 65 against Owyn, alleging that multiple products contained lead and, in some cases, cadmium, without a required warning. This led to a class-action lawsuit filed in August 2025, specifically targeting the company's chocolate Plant Protein Powder due to alleged lead content and potentially misleading marketing claims. These legal actions underscore the persistent nature of heavy metal issues within the supplement industry.

The Problem of Heavy Metals in Plant-Based Protein

It is well-established that plant-based protein powders face a higher risk of heavy metal contamination compared to dairy-based products. This is because plants naturally absorb trace metals like lead from the soil and groundwater as they grow. The concentration of these heavy metals can vary widely depending on the geographical location where the plant crops were grown, the soil quality, and the specific manufacturing processes used. The Consumer Reports investigation confirmed this, noting that, on average, the lead levels in plant-based products they tested were significantly higher than in dairy-based options.

How Owyn Addresses Testing and Safety

Owyn emphasizes its commitment to safety and states that its products adhere to government standards. The company does conduct third-party testing, but the primary focus publicly shared is on the top nine allergens, which are tested per batch using ELISA assays. Regarding heavy metals, Owyn claims compliance with California's Proposition 65 and tests every batch. However, some reviewers note that the brand is not fully transparent about its heavy metal testing, failing to disclose the accredited lab or provide Certificates of Analysis. This lack of transparency contrasts with the detailed, publicly available information on allergen testing and leaves consumers to rely on third-party investigative reports for verification.

A Comparison of Protein Supplement Safety

When evaluating protein supplements, third-party certification is a crucial factor. Certifications from organizations like NSF or Informed Sport verify that products have been tested for contaminants and banned substances. A comparison of Owyn's products against others can highlight different approaches to safety and transparency.

What This Means for Consumers

The presence of lead in Owyn and other protein shakes does not typically pose an immediate health risk, as the levels are far below those that cause immediate harm. However, lead can accumulate in the body over time, and prolonged, low-level exposure can lead to long-term health issues. Therefore, experts advise caution, especially for regular users, and recommend balancing supplement intake with a diet rich in whole food protein sources.

  • Read Production Dates: Older products might predate updated testing protocols, so checking the manufacturing date is a prudent step before buying.
  • Diversify Your Sources: Do not rely exclusively on protein shakes for your protein intake. A varied diet of whole foods is the safest approach.
  • Look for Transparency: Seek out brands that are transparent about their third-party testing, including heavy metals, and provide public access to their test results.
  • Understand Certification: Some certifications, like NSF or Informed Sport, have stringent testing for heavy metals and other contaminants, providing a higher level of assurance than brands that conduct internal or non-specific third-party testing.

Conclusion

While Owyn has faced legal allegations and was included in recent Consumer Reports findings regarding lead content, the company states its products are safe and tested for allergens. The issue of heavy metals is particularly relevant to plant-based proteins due to soil absorption. The lack of transparency from Owyn regarding specific heavy metal testing and test results leaves consumers with some uncertainty. As with all supplements, informed caution and due diligence are recommended. Consumers should consider diversifying their protein sources, checking production dates, and prioritizing brands with comprehensive and transparent third-party testing, such as those certified by NSF or Informed Sport. For the latest independent product reviews and test results, consumers can consult resources like Consumer Reports(https://www.consumerreports.org/lead/protein-powders-and-shakes-contain-high-levels-of-lead-a4206364640/).

Final Summary: Owyn protein shakes have been shown to contain detectable levels of lead in recent Consumer Reports testing and have faced previous Prop 65 violation notices. The brand emphasizes allergen testing but is less transparent about heavy metal test results, leaving consumers to navigate potential risks, particularly with older products or frequent consumption.

Frequently Asked Questions

While the FDA has reference intake levels for lead, experts widely agree there is no safe level of lead exposure, as it accumulates in the body over time. Different regulatory bodies have different thresholds, but long-term exposure is the primary concern for consumers.

Plants naturally absorb heavy metals like lead from the soil where they are grown. Since plant-based protein powders are derived from these crops, they often contain higher levels of heavy metals compared to dairy-based alternatives.

In 2020, Owyn received Proposition 65 violation notices concerning lead and cadmium in its products. A class-action lawsuit was also filed in August 2025 regarding alleged lead content. The outcomes of all related settlements have not been widely publicized, but the legal filings are documented.

Owyn claims to test every batch for heavy metals but does not typically publish the Certificates of Analysis or accrediting lab details. To be certain, you must trust the company's internal testing or seek brands that are more transparent or certified by third-party organizations like NSF.

For most people, the lead levels found in Owyn's products are not high enough to cause immediate harm. However, due to the cumulative nature of lead poisoning, experts recommend limiting intake, especially for daily use. Diversifying your protein sources is a prudent approach.
