Black seed oil

Also called black cumin seed oil, nigella sativa, kalonji.

The best price per 1 g and per month, form by form, across 2 UK retailers, and where to buy it cheapest. A unit for comparing, not advice.

Comparing black seed oil

We count the black seed oil a label states per serving, whatever the pack size or the serving size, so every product sits on one scale. 1 g is our unit for comparing prices, not a dose to take: the label’s directions and a pharmacist decide that.

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.
