Sulforaphane

Also called broccoli sprout extract, broccoli extract, glucoraphanin and 2 more

brocco, truebroc.

The best price per 10 mg and per month, form by form, across 2 UK retailers, and where to buy it cheapest. A unit for comparing, not advice.

Comparing sulforaphane

We count the sulforaphane a label states per serving, whatever the pack size or the serving size, so every product sits on one scale. Sulforaphane comes as sulforaphane and broccoli extract (by glucoraphanin), 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 sulforaphane with other ingredients are listed separately, because their price buys more than sulforaphane. 50 mg is our unit for comparing prices, not a dose to take: the label’s directions and a pharmacist decide that.

By shop

Each shop's sulforaphane products, with where its cheapest sits in the market.

How we work out these prices

We count the weight of extract per serving. Where a label quotes a “whole herb equivalent” (for example “5,000 mg from a 10:1 extract”), we use the actual extract weight. Branded, standardised extracts are compared separately from unbranded ones.

What is the best price per 50 mg of sulforaphane today?

On 20 October 2026: broccoli extract (by glucoraphanin) from 18p per 50 mg (Healf) and sulforaphane from 31p per 10 mg (Healf). The forms differ in what they contain, so this is a fact about price and not a recommendation of one over another.

How long does a pack of sulforaphane last?

At one 50 mg dose a day, the packs we price last from 18 days to 5 months; the middle one lasts 21 days. Each row says how long its pack lasts at the dose you enter.

What does “per 50 mg” mean?

It is the unit we use to put every product on the same scale: the price of 50 mg of sulforaphane, 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 sulforaphane 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: Sulforaphane; Broccoli extract (by glucoraphanin).

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.
