Milk thistle

Also called silymarin, silybum marianum, silybin, silibinin.

The best price per 150 mg and per month, form by form, across 6 UK retailers, and where to buy it cheapest. A unit for comparing, not advice.

Comparing milk thistle

We count the silymarin a label states per serving, whatever the pack size or the serving size, so every product sits on one scale. Products that combine milk thistle with other ingredients are listed separately, because their price buys more than silymarin. 150 mg is our unit for comparing prices, not a dose to take: the label’s directions and a pharmacist decide that.

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 does “per 150 mg” mean?

It is the unit we use to put every product on the same scale: the price of 150 mg of silymarin, 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 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.
