The Active Ingredient Is: Butyric Acid

Butyric acid is a short-chain fatty acid naturally produced by gut bacteria and is supplied here as a stabilized, soluble free fatty acid in a proprietary delivery matrix.

This formula also includes a CyLoc alpha dextrin fibre matrix with a DexKey release system to enhance solubility and absorption, and to aid palatability.

What Does Butyric Acid Do?

Dr. Dalile of Ghent University found that butyrate plays a role in gut health and may influence gut-brain axis function through its anti-inflammatory and barrier-supporting effects.

Butyric acid supports normal intestinal barrier integrity and supports gut microbiome balance as part of a broader gut-brain axis context, with the formulation designed to optimise delivery.
