Rumenic acid

Rumenic acid (CAS 2540-56-9), also commercially referenced as cis-9,trans-11-CLA, is the predominant naturally occurring isomer of conjugated linoleic acid found in ruminant-derived dairy and meat fats.

It is sourced for use as a bioactive fatty acid ingredient in nutritional, feed, and functional food applications where specific CLA isomer identity is a formulation requirement for the end product.

In dietary supplement manufacturing, it is used where formulators require the authenticated natural CLA isomer rather than synthetic blends, supporting label differentiation in softgel and encapsulated formats.

Functional food producers incorporate it into fortified dairy analogues, spreads, and nutritional bars targeting defined CLA content claims. In animal nutrition, it is evaluated as a feed additive.

This ingredient helps influence milk fat composition and body condition in dairy cattle. Pharmaceutical and nutraceutical researchers also source it as a reference standard or active ingredient for clinical use.

Rumenic acid is available as a purified liquid or oil, typically supplied in high-purity research and commercial grades with isomer content specified by percentage for industrial buyers.

Food-grade and feed-grade specifications are the most commercially relevant, with purity levels commonly ranging from 90% to 95%+ isomer concentration depending on the specific application.

Packaging is generally offered in small quantities for research use and bulk formats for industrial formulators. All batches are tested to ensure they meet rigorous industry quality standards.
