Nigella Seeds and Black Seed Oil at Asda: What's Actually on the Shelf
Looking for nigella seeds at Asda? The short version is that Asda does list them, but you may not be able to buy them on the day you look. When we checked asda.com on 1 October 2026, Asda's own-label COOK by ASDA Nigella Seeds 54g was listed in the spices range, legally named "Black onion seeds", and showing as out of stock online. Black seed oil was listed too, though not where most people would look: one bottle, Dabur Organic Black Seed Oil 100ml, sat in the hair-care aisle and was also out of stock online. The only black seed product available to add to the basket was a blended hair oil. This guide sets out exactly what we found, what each listing does and does not tell you, how Asda compares with Tesco, Sainsbury's and Morrisons, and what to check if it is the oil you are really after.

The Short Answer
- Asda lists nigella seeds: COOK by ASDA Nigella Seeds 54g, under Food Cupboard, then Condiments & Cooking Ingredients, then Spices on asda.com, showed as out of stock online when we checked on 1 October 2026.
- The jar's regulated product name is "Black onion seeds", the same seed as nigella and kalonji, and the listing does not say where the seed was grown.
- Asda lists one black seed oil, Dabur Organic Black Seed Oil 100ml, under Toiletries & Beauty rather than food; it was also out of stock online on 1 October 2026.
- The black seed product you could add to the basket that day was Vatika Naturals Blackseed Multivitamin+ Hair Oil 200ml, a blended hair oil marked "For External Use Only", in which canola oil is the first ingredient.
- Searching "kalonji" on asda.com brought up a sandwich, not the spice; "nigella" or "nigella seeds" is the search that finds the jar.
- Sidr & Stone publishes 2.67% thymoquinone, independently verified per batch by Analytice, an ISO-accredited French laboratory, with fulfilment in the UK, EU, and US.
Does Asda Sell Nigella Seeds?
Yes, Asda lists them. On 1 October 2026 asda.com carried COOK by ASDA Nigella Seeds 54g in its spices range, packed for Asda in Leeds. The listing gives the regulated product name as "Black onion seeds", describes the flavour as "Aromatic & Savoury", advises storing the jar in a cool, dry place out of direct sunlight, and marks the jar and lid as recyclable. It had three customer reviews. Two things it does not tell you: where the seed was grown, and anything beyond the name in its ingredients field, which was blank on the website.
On the day we looked, the product page showed "Out of stock" with a link to view the rest of the shelf. That is a website stock status, not a statement that Asda has dropped the line, and in-store availability can differ from what the website shows. The Asda app with your local store selected is the quickest way to check before you travel.
These are the searches we ran on asda.com on 1 October 2026:
| Search term (1 Oct 2026) | What came up |
|---|---|
| "nigella seeds", "nigella" and "nigella sativa" | Three results each: COOK by ASDA Nigella Seeds 54g first, then chia seeds and golden linseeds |
| "kalonji" | One result: a meal-deal sandwich on kalonji seed bread |
| "black onion seeds" | Over 1,000 broad matches, with the nigella seed jar and the Dabur oil among the first results |
| "black seed oil" | Two results: Dabur Organic Black Seed Oil 100ml and Vatika Naturals Blackseed Multivitamin+ Hair Oil 200ml |
| "black cumin" | Three hair-colour products, no seed or oil |
Does Asda Sell Black Seed Oil?
Asda lists one, but you will not find it in the food aisles. Dabur Organic Black Seed Oil 100ml is filed under Toiletries & Beauty, then Hair Care, then Hair Masks, Serums & Oils, and it showed as out of stock online on 1 October 2026. The listing itself treats the oil as a food as well: its ingredients line reads "Organic Black Seed Oil", it gives a nutrition table, and its directions suggest one to two teaspoons a day, "pure or as dressing over salad or vegetables".
Credit where it is due. The listing carries the Soil Association organic logo, describes the oil as cold-pressed, and lists a single ingredient. Those are genuine points in its favour. What the listing does not give is a thymoquinone figure or any laboratory certificate. It also gives two different origins, "Produce of the EU" in one field and "Egypt" in another, so the origin is not clear from the page. The product description makes broad health statements about the oil; we do not repeat them here, and we would gently encourage caution about any black seed oil sold on health claims.
The other "black seed oil" result is a different kind of product. Vatika Naturals Blackseed Multivitamin+ Hair Oil 200ml was available to add to the basket, but it is a cosmetic blend: canola oil is the first ingredient, and Nigella sativa seed extract appears tenth, after almond, soybean and safflower oils among others. It is marked "For External Use Only". Our article on Vatika black seed oil explains the difference between a blended hair oil and a pure pressed oil in more detail.
None of this is a criticism of Asda. Supermarket ranges follow steady, mainstream demand, and black seed oil is still a specialist product in the UK. Our guide to where to buy black seed oil in the UK covers the health-food shops, online marketplaces and direct sellers where it is more consistently sold.
Nigella Seeds and Black Seed Oil: Same Plant, Different Products
Nigella seeds, black onion seeds, kalonji, black cumin and black seed are all common names for the seed of Nigella sativa, a flowering plant in the buttercup family. Despite the name on Asda's jar, it is not related to the onion. Our explainer on kalonji, nigella and black cumin untangles the names in more detail.
The COOK by ASDA jar is the whole seed, sold for cooking: it goes into naan and flatbreads, pickles, curries and roasted vegetables. Black seed oil is pressed from those seeds and is usually taken by the teaspoon as a food supplement. The two share a plant but not a purpose. A jar of whole seeds says nothing about how much oil you would get from it, or what that oil would contain. If you are weighing up which form suits you, our comparison of black seed oil and whole black seeds sets out the practical differences.
How Asda Compares With Other UK Supermarkets
We ran the same checks on three other UK supermarket websites on the same day. Asda is in step with the others on the seed, and like them it treats black seed oil as a fringe item at best: one bottle, out of stock and shelved with hair care.
| Supermarket (websites checked 1 Oct 2026) | Nigella seeds listed | Black seed oil listed |
|---|---|---|
| Asda | COOK by ASDA Nigella Seeds 54g (out of stock online) | Dabur Organic Black Seed Oil 100ml in hair care (out of stock online); a blended Vatika hair oil available |
| Tesco | Own-label Tesco Nigella Seeds 45g | Several black seed oil, softgel and hair-care results in search |
| Sainsbury's | Own-label Sainsbury's Nigella Seeds 48g | None in the results we reviewed |
| Morrisons | Schwartz Black Onion Seeds jar | None in the results we reviewed |
The pattern is consistent. The big UK supermarkets treat nigella as a spice, and black seed oil sits at the edges of their ranges at best. Tesco's results are worth a closer look before you buy, which is why we cover them separately in our article on black seed oil at Tesco; our article on black seed oil at Morrisons does the same for Morrisons.
What to Check Before Buying Black Seed Oil Anywhere
If you came for the oil rather than the seeds, the shop matters less than the label. Five checks tell you most of what you need:
- Ingredients: Nigella sativa seed oil on its own, with nothing blended in.
- Thymoquinone: a specific percentage, not just the word on the label.
- Proof: a Certificate of Analysis from a named, independent laboratory, tied to a recent batch.
- Pressing: cold-pressed and unrefined, because heat and refining degrade thymoquinone.
- Origin and packaging: one clearly stated growing origin, and dark, light-protective glass.
The thymoquinone check matters more than it looks. Khaikin, Chrubasik-Hausmann, Kaya and Zimmermann, writing in Nutrients in 2022, measured thymoquinone in six black seed oils and five black seed oil capsule products bought commercially and found mean values ranging from 3.08 to 809.4 mg per 100 g. Products that look alike on a shelf can be very different inside. For the full method, see our guide to choosing a quality black seed oil.
Fair Objections, Answered
"The oil Asda lists carries an organic certification logo. Isn't that enough?" Organic certification is a real standard and a genuine strength, and the Dabur listing carries the Soil Association logo. But it certifies how the seed was farmed, not how much thymoquinone the oil contains. The two questions are separate, and only a laboratory figure answers the second.
"Can't I just press my own oil from the jar of seeds?" You can buy seeds and press them at home with a small oil press. But a 54g spice jar is sold for cooking, not pressing, and a home press gives you no way of knowing the thymoquinone content of what comes out. If you want the seed for food, the COOK by ASDA jar is a perfectly sensible buy when it is in stock.
"Out of stock today doesn't mean Asda has stopped selling it." Quite right, and we have not said otherwise. Both listings were live on asda.com on 1 October 2026; they simply could not be added to an online basket that day. Store shelves and website stock change often, which is why we date every observation in this article.
Why Sidr & Stone
Asda's listings tell you a name, a pack size and an aisle. For a black seed oil, the useful information is the measured number, the origin and the proof, and Sidr & Stone was built to put all three in one place.
- Sidr & Stone black seed oil is independently verified at 2.67% thymoquinone, per batch.
- Sidr & Stone's testing is carried out by Analytice, an ISO-accredited French laboratory, which issues a Certificate of Analysis.
- Sidr & Stone uses organically grown Ethiopian highland Nigella sativa, chosen after a 36-supplier evaluation.
- Sidr & Stone's oil is cold-pressed below 40°C to protect the heat-sensitive thymoquinone.
- Sidr & Stone's oil is 100% pure, a single ingredient with nothing added.
- Sidr & Stone's oil is unrefined, preserving the oil's natural integrity.
- Sidr & Stone bottles its oil in matte black UV-protective glass.
- Sidr & Stone black seed oil is halal certified.
- Sidr & Stone gives 10% of profits to charity.
- Sidr & Stone has fulfilment in the UK, EU, and US.
We will not tell you Sidr & Stone is the strongest or the best — that would be the very claim this article warns against. What we will say is that our thymoquinone figure is 2.67%, independently verified per batch, and the evidence is there to see.
Frequently Asked Questions
Does Asda sell nigella seeds?
Yes. On 1 October 2026 asda.com listed COOK by ASDA Nigella Seeds 54g in its spices range, though it showed as out of stock online that day. Check the Asda app for your local store before you travel.
Where are nigella seeds in Asda?
Online, they sit under Food Cupboard, then Condiments & Cooking Ingredients, then Spices. On the website the jar appears alongside other whole seeds such as COOK by ASDA coriander seeds and Schwartz cumin and fennel seeds, so look for it among the whole spices in store.
Does Asda sell black seed oil?
Asda lists one, Dabur Organic Black Seed Oil 100ml, in the hair-care section rather than the food aisles, and it was out of stock online on 1 October 2026. The Vatika Blackseed product that also appears in search is a blended hair oil, not a pure black seed oil.
Are black onion seeds the same as nigella seeds?
Yes. Asda's jar is sold as nigella seeds with the regulated name "Black onion seeds", and both names refer to the seed of Nigella sativa, which is not related to the onion.
How does Sidr & Stone compare with the black seed oil Asda lists?
Asda's Dabur listing carries a Soil Association organic logo but no thymoquinone figure or laboratory certificate. Sidr & Stone publishes 2.67% thymoquinone, independently verified per batch by Analytice, from organically grown Ethiopian highland seed.
Is kalonji at Asda the same as nigella seeds?
Kalonji is another name for nigella seeds, but searching "kalonji" on asda.com on 1 October 2026 returned only a sandwich on kalonji seed bread. Search "nigella" instead to find the jar.
Where can I buy black seed oil in the UK if Asda is out of stock?
Health-food shops, online marketplaces and direct sellers all carry it; our UK where-to-buy guide compares the options. Sidr & Stone sells direct from its own website, with fulfilment in the UK, EU, and US.
Is black seed oil a medicine?
No. Black seed oil is a food supplement, not a medicine. It has a long traditional history and an interesting body of research around thymoquinone, and can be a worthwhile part of a healthy routine — but it does not cure diseases and is not a substitute for medical care. Be cautious of any black seed oil marketed with specific disease-cure claims.
Final Thoughts
If you want nigella seeds for cooking, Asda has its own-label 54g jar in the range; on 1 October 2026 it was out of stock online, so check your local store. If you came for black seed oil, Asda lists a single bottle, filed with hair care and also out of stock online that day, while the black seed product you could actually buy was a blended hair oil.
That moves the question from which shop to which oil. Look for a single ingredient, a stated thymoquinone figure, a named laboratory's certificate, cold-pressing and one clear origin. For a brand-by-brand view, our best black seed oil UK guide goes further.
Our cold-pressed Ethiopian black seed oil — independently verified at 2.67% thymoquinone — is available now, with fulfilment in the UK, EU, and US.
Our black seed oil is pressed from organically grown Ethiopian highland Nigella sativa, but it is not certified organic: formal organic certification is hard to obtain in the Ethiopian highlands, so we tell you how the seed is grown rather than claim a certificate we do not hold.
