Oat avenanthramides
What it is
Polyphenolic amides unique to oats (primarily avenanthramides A, B, and C), distinct from the beta-glucan fibre fraction. Unlike oat beta-glucan which acts in the gut lumen, avenanthramides are absorbed systemically and exert anti-inflammatory, vasodilatory (via nitric oxide), and antioxidant effects. Human trials show reductions in LDL oxidation, improved endothelial function, and reduced platelet aggregation. Complementary to — not duplicative of — oat fibre benefits.
Dose
50–250 mg avenanthramide-rich oat extract daily
Time of day & tips
Available as standardised oat extract or concentrated avenanthramide complex; take with meals; synergistic with oat beta-glucan for complete oat benefits
