Eurofins Nutrition Analysis Center launches MSM analysis for pet joint health supplements

Des Moines, IA — December 22nd, 2025 — The Eurofins Nutrition Analysis Center in Des Moines, Iowa, is pleased to announce the launch of a specialized analytical method for Methylsulfonylmethane (MSM) in pet chew supplements. This new capability supports the growing demand for validated testing in the pet supplement market, particularly in preventative joint health.

MSM, or dimethyl sulfone (DMSO₂), is an organosulfur compound widely used in pet supplements, often alongside chondroitin sulfate and glucosamine. In companion animals, it is associated with joint support, reduced inflammation, antioxidant activity, and skin and coat benefits.

Key highlights of the new method

• Enhanced sensitivity: Detects MSM at concentrations as low as 0.05%, enabling precise quantification.
• Improved extraction efficiency: Optimized solubility in the extraction solution ensures higher recovery rates and reproducibility.
• Broader applicability: Designed to accommodate diverse pet chew formulations, including complex matrices with varying excipients and flavoring agents.

This advancement provides manufacturers with a reliable tool to substantiate label claims, ensure product integrity, and meet evolving industry and consumer expectations.

“Eurofins is committed to advancing analytical science in the pet supplement sector,” said Kristian Lentz, President of Eurofins Nutrition Analysis Center, “Our new MSM method delivers the sensitivity and accuracy needed to support product innovation and compliance in this rapidly growing market.”
