Chlorella

Also called chlorella vulgaris, chlorella pyrenoidosa, broken cell wall chlorella.

The best price per 3 g and per month, form by form, across 4 UK retailers, and where to buy it cheapest. A unit for comparing, not advice.

Comparing chlorella

We count the chlorella a label states per serving, whatever the pack size or the serving size, so every product sits on one scale. Products that combine chlorella with other ingredients are listed separately, because their price buys more than chlorella. 3 g 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 chlorella cheapest in the UK?

On 20 October 2026, the cheapest chlorella per dose from a UK seller was Chlorella at Healf (34p per 3 g, £10.31 a month). Then Chlorella Rich in Chlorophyll 3000mg 120 Tablets at Holland & Barrett (59p per 3 g, £17.68 a month) and Organic Spirulina & Chlorella Capsules at WeightWorld (73p per 3 g, £21.94 a month). That is by price per 3 g, across 4 UK retailers and 6 products, with every price checked daily; the table above shows the working for each.

What is the best price per 3 g of chlorella today?

34p per 3 g, for Chlorella at Healf (34p per 3 g, £10.31 a month), on 20 October 2026. The dearest of the 6 products we price is £2.83 per 3 g, and the middle one is £1.03.

How much does chlorella cost per month?

At one 3 g dose a day, the cheapest works out at £10.31 a month, for Chlorella at Healf, on 20 October 2026. Across the 6 products we price it runs from £10.31 to £84.75 a month. A month is 30 days, and the figure follows the dose you enter in the table.

How long does a pack of chlorella last?

At one 3 g dose a day, the packs we price last from 12 days to 3 months; the middle one lasts 28 days. Each row says how long its pack lasts at the dose you enter.

What does “per 3 g” mean?

It is the unit we use to put every product on the same scale: the price of 3 g of chlorella, 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.
