Evening primrose (GLA)

Also called evening primrose, evening primrose oil, epo, GLA.

The best price per 100 mg GLA (gamma-linolenic acid) and per month, form by form, across 7 UK retailers, and where to buy it cheapest. A unit for comparing, not advice.

Comparing evening primrose (GLA)

We count the GLA (gamma-linolenic acid) a label states per serving, whatever the pack size or the serving size, so every product sits on one scale. Products that combine evening primrose (GLA) with other ingredients are listed separately, because their price buys more than GLA (gamma-linolenic acid). 100 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 evening primrose (GLA) products, with where its cheapest sits in the market.

How we work out these prices

We count GLA (gamma-linolenic acid) — the components stated on the label — not the weight of the oil. A 1,000 mg capsule of oil can contain very different amounts of GLA (gamma-linolenic acid). Products that state only the oil weight are left out until the content is confirmed.

Questions

Where can I buy evening primrose (GLA) cheapest in the UK?

On 20 October 2026, the cheapest evening primrose (GLA) per dose from a UK seller was Evening Primrose Softgels at Myprotein (8p per 100 mg GLA (gamma-linolenic acid), £2.40 a month). Then Evening Primrose Oil 1000mg at ZipVit (9p per 100 mg GLA (gamma-linolenic acid), £2.78 a month) and Evening Primrose Oil Softgels at WeightWorld (9p per 100 mg GLA (gamma-linolenic acid), £2.83 a month). That is by price per 100 mg GLA (gamma-linolenic acid), across 7 UK retailers and 15 products, with every price checked daily; the table above shows the working for each.

What is the best price per 100 mg GLA (gamma-linolenic acid) of evening primrose (GLA) today?

8p per 100 mg GLA (gamma-linolenic acid), for Evening Primrose Softgels at Myprotein (8p per 100 mg GLA (gamma-linolenic acid), £2.40 a month), on 20 October 2026. The dearest of the 15 products we price is 35p per 100 mg GLA (gamma-linolenic acid), and the middle one is 13p.

How much does evening primrose (GLA) cost per month?

At one 100 mg dose a day, the cheapest works out at £2.40 a month, for Evening Primrose Softgels at Myprotein, on 20 October 2026. Across the 15 products we price it runs from £2.40 to £10.54 a month. A month is 30 days, and the figure follows the dose you enter in the table.

Do bigger evening primrose (GLA) packs cost less per dose?

Not here: on 20 October 2026, the 6 packs that last more than six months average 17p per 100 mg GLA (gamma-linolenic acid), against 16p for the 9 that last six months or less. The table marks the cheapest pack that lasts six months or less as the best value for anyone who would rather not buy a year at once.

How long does a pack of evening primrose (GLA) last?

At one 100 mg dose a day, the packs we price last from 27 days to 11 months; the middle one lasts 5 months. Each row says how long its pack lasts at the dose you enter.

What does “per 100 mg GLA (gamma-linolenic acid)” mean?

It is the unit we use to put every product on the same scale: the price of 100 mg of GLA (gamma-linolenic acid), 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.
