Kaneka Nutrients Releases Third Phase of Ubiquinol Authenticity Testing Results

Kaneka Nutrients has published results from a third round of independent market testing aimed at verifying whether products labeled as ubiquinol on the U.S. market actually contain the ingredient at stated levels.¹ The Pasadena, Texas-based company, a division of Kaneka North America LLC, manufactures Kaneka Ubiquinol using a proprietary yeast fermentation process. According to the company, this method produces a form of ubiquinol that is bioidentical to what the body naturally generates and does not contain the cis-isomers associated with synthetic CoQ10 manufacturing.

For the third phase, Kaneka Nutrients purchased 4 products through Amazon and shipped them directly to third-party laboratories for analysis, with no handling by non-lab personnel prior to testing. Eurofins Lab results showed that none of the 4 products met their label claims. One product, labeled at 200 mg per capsule, tested at less than 0.001 mg per serving; the remaining three products, each labeled between 200 mg and 300 mg per serving, tested at less than 0.003 mg per serving. Kaneka's own internal lab results for these samples were listed as inconclusive.

How Is Kaneka Nutrients Responding to the Results?

The company stated that where testing raises authenticity concerns, Kaneka Corporation may pursue legal or regulatory remedies and, where warranted, public disclosure. Kaneka Nutrients also pointed to the Kaneka Quality Seal as a tool for consumers and retailers to verify authentic product.

Terese Mansell, Vice President of Kaneka's Nutrients Division, highlighted the company's stewardship of the ubiquinol category. “We built this category, which means we have an obligation to protect it,” said Mansell. “That stewardship extends beyond our own manufacturing standards to what consumers find on shelves.”

What Did the Second Phase of Testing Show?

The third phase follows a second phase disclosed in December 2025, which expanded the surveillance program in response to what the company described as growing concerns about misleading label claims.² That release covered 9 additional products purchased through Amazon, all of which Eurofins Lab testing found did not meet label claims, with per-serving amounts measured at less than 0.005 mg.

That release also included a statement from Marko Rosa, CEO of Health Thru Nutrition. “Kaneka’s recent testing highlights a critical and growing need for stronger transparency, authentication, and accountability across the supplement industry,” said Rosa. “When a product is labeled as a specific ingredient—whether Ubiquinol or any other bioactive compound—it must be genuine, independently verified, and fully traceable from raw material to finished product. At Health Thru Nutrition, we support efforts that protect ingredient integrity and consumer trust, because these standards are not optional; they are fundamental to the future of our industry and consumer safety.”

Mansell noted at the time that the first phase of testing had revealed significant concerns about products failing to meet label claims.

How Did the Surveillance Program Begin?

The program was first announced in May 2025, when Kaneka Nutrients disclosed initial test results for 11 products.³ As in later phases, products were purchased via Amazon and sent directly to labs for testing without intermediate handling. Eurofins Lab results for that initial round showed each product tested below its labeled dosage, with several results falling below 0.005 mg per serving and two results reported as inconclusive.

“By exposing products that misrepresent their contents, we aim to prevent misleading claims that undermine trust, devalue authentic ubiquinol products, and compromise health outcomes,” Mansell had stated.
