Ergothioneine

Also called L-ergothioneine, ergoneine, ergo.

The best price per 5 mg and per month, form by form, across 1 UK retailer, and where to buy it cheapest. A unit for comparing, not advice.

Comparing ergothioneine

We count the L-ergothioneine a label states per serving, whatever the pack size or the serving size, so every product sits on one scale. Products that combine ergothioneine with other ingredients are listed separately, because their price buys more than L-ergothioneine. 5 mg is our unit for comparing prices, not a dose to take: the label’s directions and a pharmacist decide that.

Why is a product I have seen in the shops missing?

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.
