Oat beta-glucan

Also called beta glucan, beta-glucans, wellmune.

The best price per 250 mg and per month across 1 UK retailer, and where to buy it cheapest. A unit for comparing, not advice.

Comparing beta-glucan

We count the beta-glucan a label states per serving, whatever the pack size or the serving size, so every product sits on one scale. Beta-glucan comes as oat beta-glucan and yeast beta-glucan (1,3/1,6), and each form has its own table, because someone buying one would not usually take another as a like-for-like substitute. Products that combine beta-glucan with other ingredients are listed separately, because their price buys more than beta-glucan. 250 mg is our unit for comparing prices, not a dose to take: the label’s directions and a pharmacist decide that.

Prices last checked: 20 October 2026. Ranked purely by price per 250 mg — a comparison unit, not a recommendation. We earn commission when you buy through these links; it never affects the order.
