Astaxanthin

Also called astareal, astapure.

The best price per 4 mg and per month, form by form, across 7 UK retailers, and where to buy it cheapest. A unit for comparing, not advice.

Comparing astaxanthin

We count the astaxanthin a label states per serving, whatever the pack size or the serving size, so every product sits on one scale. Products that combine astaxanthin with other ingredients are listed separately, because their price buys more than astaxanthin. 4 mg is our unit for comparing prices, not a dose to take: the label’s directions and a pharmacist decide that.

Questions

Where can I buy astaxanthin cheapest in the UK?

On 20 October 2026, the cheapest astaxanthin per dose from a UK seller was Natural Astaxanthin Softgels at WeightWorld (4p per 4 mg, £1.19 a month). Then Astaxanthin Soft Gels at Myprotein (4p per 4 mg, £1.33 a month) and Astaxanthin Soft Gels at Myprotein (5p per 4 mg, £1.43 a month). That is by price per 4 mg, across 7 UK retailers and 14 products, with every price checked daily; the table above shows the working for each.

What is the best price per 4 mg of astaxanthin today?

4p per 4 mg, for Natural Astaxanthin Softgels at WeightWorld (4p per 4 mg, £1.19 a month), on 20 October 2026. The dearest of the 14 products we price is 68p per 4 mg, and the middle one is 34p.

How much does astaxanthin cost per month?

At one 4 mg dose a day, the cheapest works out at £1.19 a month, for Natural Astaxanthin Softgels at WeightWorld, on 20 October 2026. Across the 14 products we price it runs from £1.19 to £20.40 a month. A month is 30 days, and the figure follows the dose you enter in the table.

How long does a pack of astaxanthin last?

At one 4 mg dose a day, the packs we price last from 38 days to 1.3 years; the middle one lasts 2 months. Each row says how long its pack lasts at the dose you enter.

What does “per 4 mg” mean?

It is the unit we use to put every product on the same scale: the price of 4 mg of astaxanthin, 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.
