What it is
A natural fibre from oats, barley, and certain mushrooms that supports immune function and lowers cholesterol. EFSA approved a health claim for oat beta-glucan reducing LDL cholesterol at 3 g/day. The yeast-derived 1,3/1,6 form activates innate immune cells (macrophages, NK cells) most effectively. Very safe with no serious side effects.
