Oat Beta-Glucan

Metabolic Evidence: strong

Overview

Oat beta-glucan (C18H32O16 repeating unit) is a soluble polysaccharide fiber from oat bran that lowers LDL cholesterol by binding bile acids and increasing fecal excretion, upregulating hepatic LDL receptors. Doses ≥3 g/day produce consistent LDL reductions of 0.25 mmol/L (meta-analysis of 28+ RCTs) — EFSA-approved health claim for LDL cholesterol. Also modulates gut immunity via toll-like receptor activation on intestinal epithelial cells. INTERACTIONS: may slow/reduce absorption of co-administered medications due to viscosity — take drugs 1–2 hours before; additive hypoglycemic effect with antidiabetic medications (monitor blood glucose). Well-tolerated; high doses may cause bloating and flatulence due to fermentation.
