Beta-glucans
Also known as: oat beta-glucan, beta-glucan
Beta-glucans are soluble fibres from oats, barley, yeast and mushrooms. Oat and barley beta-glucans have an EU-approved health claim for lowering LDL cholesterol at an intake of 3 g per day.
What it is used for
- Lower LDL cholesterol (oat and barley) – strong evidence, approved EFSA claim
- Smaller blood sugar rise after meals – moderate evidence
- Immune support (yeast and mushroom) – weak evidence
Forms and how they differ
oat or barley
for cholesterol and blood sugar, powder or oat bran
yeast (1,3/1,6)
mainly for immunity
mushroom
from oyster mushroom or others, immunity
Pairs well with
