Nature's Blends Black Seed Oil: An Honest Comparison
By Yusuf Elsayed, Founder of Sidr & Stone · Last updated 21 October 2026Share
Nature's Blends black seed oil is a UK wellness brand's raw, cold-pressed oil from Ethiopian Nigella sativa, sold as a liquid (50ml and 100ml) and as capsules. The brand says the oil is lab tested and gives a thymoquinone figure of 2.5%, which it describes as a minimum. Retailer listings checked on 21 October 2026 show the 100ml bottle at £15.99 (Salam Occasions) and describe the oil as "100% natural cold pressed Nigella Sativa Oil"; no batch certificate is shown.
The Short Answer
- Nature's Blends (often searched as "Nature's Blend") is a UK wellness brand selling Ethiopian cold-pressed Nigella sativa oil and capsules.
- It is a transparent option by category standards: the brand states a 2.5% thymoquinone figure, says its oil is lab tested, and is open about its Ethiopian sourcing.
- Its range is broad, with liquid oil, capsules, and other products such as manuka honey and shilajit.
- The distinction worth understanding is between a stated minimum benchmark and a specific figure measured for a batch, with a certificate you can see.
- The 100ml oil was listed at £15.99 by the UK retailer Salam Occasions when checked on 21 October 2026.
Who Nature's Blends Is, and What They Actually Sell
Nature's Blends is a UK-based natural wellness brand with a range that goes well beyond black seed oil: manuka honey, shilajit resin and a handful of other oils sit alongside it. The black seed oil is sold in two main forms: a raw, cold-pressed liquid oil in 50ml and 100ml sizes, and capsules for people who would rather not taste it.
The brand is open about sourcing its oil from Ethiopia, one of the original homelands of Nigella sativa and a region associated with high-thymoquinone seed. It describes direct relationships with small-scale Ethiopian farmers, says its oil is lab tested, and prints a thymoquinone benchmark rather than staying silent on the number. Its capsules are made in a GMP-certified UK facility. Retailer copy describes the oil as pressed once, with no added heat, additives or preservatives, and PlantX lists it as gluten-free and suitable for vegetarians and vegans.

The Thymoquinone Figure: What 2.5% Tells You
Thymoquinone, usually shortened to TQ, is the most-researched compound in black seed oil. It is the figure careful buyers compare, because it says something real about the seed and the pressing behind the bottle.
Nature's Blends states that its oil is tested to contain a minimum of 2.5% thymoquinone; retailer listings phrase it as "Contains 2.5% thymoquinone" and "our oil was given a 2.5% TQ percentage". That is a clear benchmark and far better than the silence you get from most brands. It is worth being precise about what a minimum is, though: a floor the brand commits to clearing, not necessarily the measured result of the bottle in your hand. A per-batch figure published with its certificate shows more of the working. If that matters to you, ask the brand for the certificate covering your batch.

Capsules or Liquid Oil? The Format Changes the Question
Nature's Blends sells capsules prominently, and it is easy to see why: they are tasteless, portable and pre-measured, which suits people new to black seed oil or put off by its sharp, peppery flavour. But the format changes what you are buying.
With a liquid oil, what you see is what you take: a single ingredient, poured by the drop, with the colour and aroma of the oil in plain view. With capsules, the oil is sealed inside a shell, and the dose per capsule is small, so the amount of oil you take in a day can be lower than a teaspoon of liquid. Capsules trade a little quantity and visibility for a lot of convenience. If thymoquinone is why you are buying, do the simple sum: oil per capsule, capsules per day, and how that compares with the liquid dose.

What to Check When You Buy Online
Black seed oil is a quality-variable specialist product. When you are buying online, a few checks do most of the work: a single ingredient (pure Nigella sativa seed oil, nothing added), a specific thymoquinone figure backed by a certificate of analysis from a named, independent testing provider, dark UV-protective glass, and cold-pressing. For a fuller walkthrough, see our guide to choosing a quality black seed oil.
Nature's Blends' pages also list a range of health benefits for the oil. Read those as the brand's marketing rather than established findings: black seed oil is a food supplement with an interesting research story, not a medicine.
Is Nature's Blends a Good Brand?
Measured against those checks, Nature's Blends does well on most of them: Ethiopian seed, cold-pressed, a stated thymoquinone figure, lab testing, and a sensibly priced 100ml bottle. The one place a buyer can ask for more is the last step of verification: the actual per-batch number and the certificate behind it.

How It Compares With an Independently Tested Oil
On paper, Nature's Blends' stated 2.5% is close to our own figure, and it is sold by UK retailers such as Salam Occasions and PlantX, which is convenient. Where Sidr & Stone goes further is the evidence: every batch is independently tested, the first batch measured 2.67% thymoquinone (Analytice, August 2025), and the certificate is published for anyone to read.
| Nature's Blends | Sidr & Stone | |
|---|---|---|
| Seed origin | Ethiopia | Ethiopian highlands, organically grown |
| Thymoquinone | 2.5%, stated as a minimum | 2.67% (first batch, Aug 2025), measured |
| Testing evidence | Lab tested, per the brand; no certificate shown on listings | Every batch independently tested (via Analytice); certificate published |
| Formats | Liquid (50ml, 100ml) and capsules | Liquid, 100ml, matte black glass |
| Fulfilment | UK retailers and its own store | UK, EU, and US |
If capsules or picking it up from a UK retailer matter most, Nature's Blends is a sound choice; if you want every batch independently tested and the certificate published, ours is built for that.

Frequently Asked Questions
What is Nature's Blends black seed oil?
It is the black seed oil sold by Nature's Blends, a UK wellness brand. The oil is raw, cold-pressed Ethiopian Nigella sativa, available as a liquid in 50ml and 100ml bottles and as capsules, with a stated thymoquinone figure of 2.5%, which the brand describes as a minimum.
Is Nature's Blends black seed oil any good?
By the standards of the category, it is a reasonable and transparent option: Ethiopian seed, cold-pressed, lab tested, with a thymoquinone figure on the label. The main thing a careful buyer can ask for beyond that is a specific per-batch figure with a certificate to view, rather than a stated minimum.
How much does Nature's Blends black seed oil cost?
When checked on 21 October 2026, the UK retailer Salam Occasions listed Nature's Blends Raw Virgin Ethiopian Black Seed Oil (100ml) at £15.99, with a 50ml bottle and 60-capsule packs also listed. Prices vary between retailers and the brand's own store, so compare before buying.
What is the difference between a 2.5% minimum and a verified per-batch figure?
A 2.5% minimum is a floor the brand commits to clearing. A verified per-batch figure is the actual measured result for that production run, published with its certificate of analysis. Both can be honest; the per-batch figure simply shows more of the underlying evidence.
Are black seed oil capsules as good as the liquid?
They contain the same kind of oil, but each capsule holds a small, fixed amount, so a daily capsule dose often delivers less oil than a teaspoon of liquid. Capsules win on convenience and taste; liquid usually wins on the amount of oil, and so thymoquinone, you actually take.
Is Ethiopian black seed oil better?
Ethiopian highland seed is associated with high thymoquinone in published research, so it is a promising starting point. But origin alone is not a guarantee: cold-pressing, careful storage and independent testing are what turn a promising start into a confirmed result.
How does Nature's Blends compare with Sidr & Stone?
Both use Ethiopian seed and cold-pressing. Nature's Blends states a 2.5% thymoquinone minimum and sells capsules as well as oil. Sidr & Stone sells one liquid oil with every batch independently tested; the first batch (August 2025) measured 2.67% thymoquinone, with the certificate published.
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, 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
Nature's Blends is one of the better names to land on if you are comparing black seed oil in the UK. It does the right things: Ethiopian sourcing, cold-pressing, lab testing, and a thymoquinone figure printed openly rather than hidden, at a sensible price. If you are weighing it up, you are not weighing up a poor product.
If you would rather see an independently measured figure and its certificate, our cold-pressed Ethiopian black seed oil has every batch independently tested, with the first batch measuring 2.67% (Analytice, August 2025) thymoquinone.
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.
