Beta-glucan
Also called beta glucan, beta-glucans, wellmune.
The best price per 250 mg and per month, form by form, across 2 UK retailers, 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.

Which beta-glucan form is cheapest per dose?

What does “per 250 mg” mean?
It is the unit we use to put every product on the same scale: the price of 250 mg of beta-glucan, whatever the pack size or serving size. It is a comparison unit, not a recommendation of how much to take. Use the “Your daily dose” box to see costs at the amount you actually take.
Why are the beta-glucan forms in separate tables?
We only rank products against others of the same form, because someone buying one form would not usually see another as a like-for-like substitute on price. Forms we compare separately: Oat beta-glucan; Yeast beta-glucan (1,3/1,6).
Why is a product I have seen in the shops missing?
If a retailer’s listing does not let us confirm the amount per serving, the pack size or the form, we do not guess and we do not show the product. It appears once its label has been read and confirmed.
How up to date are the prices?
Prices on this page were last checked on 20 October 2026. Every table shows the date its prices were checked. Always confirm the price on the retailer’s site before buying.
Do retailers pay to appear higher?
No. We earn a commission when you buy through our links, but the order is set only by price per dose. No retailer or brand can pay for position.
