Black Seed Oil at GNC: What's on the Shelf and What to Check
Does GNC sell black seed oil? Yes, though the range is smaller and more capsule-heavy than you might expect. When we searched gnc.com for "black seed oil" on 1 October 2026, it returned nine products. Six were black seed oil on its own: GNC's own SuperFoods softgels, three Amazing Herbs products, and capsules from Portions Master and SNAP Supplements. The other three were blends that include black seed among other ingredients. Only one of the six was a liquid oil. This guide reads each GNC listing for what it actually declares (thymoquinone, pressing, seed origin and form) and what it leaves out. It is a dated snapshot of the website rather than any one store, so use it as a way of reading the shelf, not a permanent map of it.

The Short Answer
- GNC.com returned nine products for "black seed oil" on 1 October 2026; six were single-ingredient black seed oil products and three were blends.
- Five of the six were softgels or capsules. The only liquid oil was Amazing Herbs Black Seed, in an 8 oz bottle.
- GNC's own-label SuperFoods Black Seed Oil (500 mg softgels) gives no thymoquinone figure, no pressing method and no seed origin on its listing.
- Amazing Herbs was the only brand at GNC to print a thymoquinone figure, but on two of its three listings the description and the supplement facts panel give figures that do not match.
- None of the six GNC listings stated where the seed was grown, and none linked to a batch certificate of analysis.
- 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 GNC Sell Black Seed Oil?
Yes. On 1 October 2026, a search of gnc.com for "black seed oil" returned nine products, six of them black seed oil on its own, from GNC's own SuperFoods label, Amazing Herbs, Portions Master and SNAP Supplements. Most are softgels or capsules; one is a liquid oil. Two of the six were marked "Online Only".
The three remaining results were blends: two Nature's Fusions oil of oregano products and a Yemaya Organics multi-mineral, each of which lists black seed among several ingredients. GNC's search groups them together because they share an ingredient, so if you want plain black seed oil, read the ingredient panel before the product name. Searching "black cumin" on GNC returned two of the same products, and "nigella sativa" returned none, so "black seed oil" is the search to use. For every other US store we checked the same day, see our store-by-store guide to where to buy black seed oil in the US.
What Each GNC Label Declares
We opened all six single-ingredient listings on gnc.com on 1 October 2026 and recorded what each listing itself states, in its description and its supplement facts panel. "Not stated" means the listing did not say, not that the product lacks it.
| Product (as listed) | Form | Thymoquinone figure | Pressing | Seed origin | Availability |
|---|---|---|---|---|---|
| GNC SuperFoods Black Seed Oil 500 mg, 90 softgels | Softgel (gelatin) | Not stated | Not stated | Not stated | Online and stores |
| Amazing Herbs Black Seed, 8 oz | Liquid oil | "Minimum 1.2%" in description; 48 mg per 5 g serving on facts panel | Cold-pressed, unrefined, "heat-free virgin first pressing" | Not stated | Online and stores |
| Amazing Herbs Black Seed 1250 mg, 60 softgels | Softgel (halal bovine gelatin) | "Min. 0.95%" | Cold-pressed in Buford, Georgia, unrefined | Not stated | Online and stores |
| Amazing Herbs Black Seed, 90 capsules | Capsule (gelatin) | "10 mg per softgel" in description; 48 mg per 2 capsules on facts panel | Cold-pressed | Not stated | Online and stores |
| Portions Master Black Cumin Seed Oil 500 mg, 90 capsules | Vegetable capsule | Not stated | Not stated | Not stated | Online only |
| SNAP Supplements Cold Pressed Black Seed Oil, 90 softgels | Plant-based softgel | Not stated | "100% cold pressed" | Not stated | Online only |
Three things stand out. Five of the six are capsules or softgels. Only one brand prints a thymoquinone figure. And not one of the six says where its seed was grown.
GNC SuperFoods: GNC's Own Black Seed Oil
GNC SuperFoods is GNC's own label, and its Black Seed Oil comes as 500 mg softgels, 90 to a bottle, with a serving of two softgels supplying 1,000 mg of black cumin seed (Nigella sativa) oil. The only other ingredients listed are the gelatin and glycerin of the softgel shell. GNC presents it as a source of omega fatty acids, and its panel lists 400 mg of linoleic acid (omega-6) and 170 mg of oleic acid (omega-9) per serving.
That is a straightforward, single-oil product, and the fatty-acid figures are more than many labels give. What the listing does not give is a thymoquinone figure, a pressing method, a seed origin or a laboratory. If thymoquinone is the reason you are buying black seed oil, this listing does not tell you how much you are getting. It is also worth knowing that the softgel shell is gelatin, and the listing does not say what source the gelatin comes from. Own-label bottles at big US chains tend to follow this pattern, as we found with Walmart's own Spring Valley black seed oil.
Amazing Herbs at GNC: Three Products, Several Figures
Amazing Herbs is the most prominent brand on GNC's black seed oil shelf, with the only liquid oil and two capsule lines. Credit where it is due: it is the only brand at GNC to print a thymoquinone figure, its supplement facts panels give thymoquinone in milligrams, and its 1250 mg softgel listing says the product is third-party lab tested and cold-pressed in Buford, Georgia. That softgel also uses halal bovine gelatin, which the listing states plainly. Those are real strengths, and more than most of the shelf offers.
The figures themselves are worth reading slowly. The 8 oz liquid's description says it "Contains Minimum 1.2% Thymoquinone", while its supplement facts panel lists 48 mg of thymoquinone in a 5 g teaspoon, which works out at about 0.96%. The 90-capsule listing says "10mg thymoquinone per softgel", while its panel lists 48 mg for a two-capsule serving. The 1250 mg softgels say "min. 0.95%". We are not suggesting any of these figures is wrong; we are saying that two figures on the same listing that do not agree are a reason to ask the brand for the batch certificate before relying on either. We cover the brand in more depth in our honest review of Amazing Herbs black seed oil.
The listings also make health-outcome claims for the oil, which we do not repeat; we would gently encourage caution with any black seed oil sold on specific health claims rather than measured content.
Capsules and Softgels: What the Milligrams Mean
Most of what GNC sells as black seed oil is in capsule form. That suits many people: no taste, a fixed dose, easy to carry. But read the strength carefully. On the GNC SuperFoods, Portions Master and SNAP listings, "500 mg" is the weight of black seed oil in each capsule, not the amount of thymoquinone. None of those three gives a thymoquinone figure at all.
The capsule shells differ too. GNC SuperFoods and two of the Amazing Herbs products use gelatin; Portions Master uses vegetable cellulose capsules and adds vitamin E (d-alpha tocopherol acetate) and silicon dioxide; SNAP uses a plant-based softgel made with modified starch and carrageenan. None of that is a problem in itself, but it does mean "black seed oil capsules" can describe quite different products, and if the capsule source matters to you, the "Other Ingredients" line is where to look.
This matters because the spread in real products is wide. Khaikin and colleagues, writing in Nutrients in 2022, tested six black seed oils and five black seed oil capsule products bought commercially and found thymoquinone ranging from 3.08 to 809.4 mg per 100 g. Products that look alike on a shelf, or in a capsule, can be very different inside.
What to Check Before You Buy Black Seed Oil at GNC
Whichever GNC listing you are looking at, five checks will tell you most of what you need:
- Ingredients: black seed (Nigella sativa) oil on its own, if you want the oil rather than a blend.
- Thymoquinone: a specific figure, stated the same way in the description and the facts panel.
- Proof: a certificate of analysis from a named laboratory, tied to a recent batch.
- Origin and pressing: where the seed was grown and whether it was cold-pressed.
- Form: for liquid oil, dark glass rather than clear glass or plastic, since thymoquinone is light-sensitive; for capsules, the shell material.
A fair objection: "GNC is a specialist supplement chain, so surely its products are already checked?" A specialist store is a reasonable place to start, but the label is still the brand's own statement, and none of the six listings we read linked to a batch certificate a shopper can see. Another fair objection: "I just want capsules, so why does any of this matter?" It matters for the same reason: a capsule's milligrams describe the oil, not the thymoquinone in it.
On price, GNC's six single-ingredient products were listed between $24.99 and $34.99 on 1 October 2026, with GNC SuperFoods, Portions Master and SNAP at $24.99 and the Amazing Herbs 8 oz liquid at $34.99. Prices and promotions change often, and size and strength matter more than the sticker.

Why Sidr & Stone
Reading the GNC shelf shows the gap clearly: capsules measured in milligrams of oil, one brand printing thymoquinone figures that do not always agree, and no seed origins or certificates. Sidr & Stone was built to put the measured number, the origin and the proof in the same 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 GNC sell black seed oil?
Yes. On 1 October 2026 gnc.com returned nine products for "black seed oil", six of them black seed oil on its own, including GNC's own SuperFoods Black Seed Oil 500 mg softgels and Amazing Herbs' liquid oil and capsules.
Is GNC SuperFoods black seed oil cold-pressed?
Its GNC listing does not say. It lists 1,000 mg of black cumin seed oil per two-softgel serving, with fatty-acid figures, but no pressing method, thymoquinone figure or seed origin.
How do I tell which GNC black seed oil is worth buying?
Check for a single ingredient, a specific thymoquinone figure stated consistently, a named laboratory's certificate of analysis for a recent batch, and the seed origin. None of the GNC listings we read gave all four.
Does GNC sell liquid black seed oil or only capsules?
Both, but mostly capsules. On 1 October 2026 the only liquid black seed oil on gnc.com was Amazing Herbs Black Seed in an 8 oz bottle; the other five single-ingredient products were softgels or capsules.
How does Sidr & Stone compare with what GNC sells?
Sidr & Stone publishes 2.67% thymoquinone, independently verified per batch by Analytice, for a single-ingredient, cold-pressed, unrefined oil from organically grown Ethiopian highland seed. None of the GNC listings we opened stated a seed origin or linked to a batch certificate.
Is black cumin seed oil at GNC the same as black seed oil?
Yes. Black cumin seed oil, nigella sativa oil and black seed oil are names for the same oil, pressed from Nigella sativa seeds. GNC's Portions Master product uses the "black cumin" name.
Can I buy Sidr & Stone black seed oil at GNC?
No. Sidr & Stone sells direct from its own website, with fulfilment in the UK, EU, and US, so each bottle comes from our own stock with its batch verification.
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
GNC carries black seed oil, mostly as capsules, and its own SuperFoods softgel is a plain single-oil product. Amazing Herbs deserves credit for printing thymoquinone figures at all. What the GNC shelf does not do, for any of the six listings we read, is tell you where the seed was grown or show you a certificate behind a consistent thymoquinone figure.
So read the listing before the price: one ingredient, one consistent figure, a named laboratory and a stated origin. If you are comparing other US stores too, our US where-to-buy guide covers the rest.
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.
