About this supplement
Oat beta-glucan concentrate is a soluble dietary fiber extracted from the cell walls of oats (Avena sativa), specifically composed of mixed-linkage (1→3, 1→4)-β-D-glucan polymers. This viscous polysaccharide is not digested in the small intestine but is fermented in the colon. It is commercially produced as a concentrated powder or liquid extract, standardized to contain a high percentage (typically 70-95%) of beta-glucan. It is widely used in functional foods, dietary supplements, and topical skincare products due to its physiological and rheological properties.

Physical properties
Typically a fine, off-white to tan-colored powder. Highly soluble in water, forming viscous, clear to slightly opaque solutions. Hygroscopic. Molecular weight varies with processing, influencing viscosity.
How it’s made
Produced by milling oat grains (bran or whole oat flour), followed by aqueous or enzymatic extraction to solubilize the beta-glucan. The extract is then purified and concentrated using techniques like centrifugation, filtration, and precipitation with ethanol or ammonium sulfate. The final product is dried (spray-dried or drum-dried) to a powder, often standardized to a specific beta-glucan content.
