Why we added it
Black seed oil is the one supplement our team kept buying elsewhere. We wanted it cold-pressed, unrefined, in a softgel, with a certificate. So we made it.

Oil pressed from the seed of Nigella sativa, the plant behind black cumin. It has been used in kitchens and households around the Mediterranean, the Middle East and East Africa for thousands of years. Its signature compound is thymoquinone, alongside omega-3, 6 and 9 fatty acids and natural antioxidants.
Each serving of two softgels supplies 800 mg of cold-pressed, unrefined Ethiopian black seed oil. It is the only ingredient besides the softgel itself. No proprietary blend, no carrier oil, no flavouring.
Two softgels once a day, preferably before bed, as directed on the jar. Keep it in a cool, dry place away from sunlight. If you take prescription medication, are pregnant or nursing, ask your physician first.

The seed, the press, the certificate.
Black seed oil is only as good as the seed and the press. Ours is cold-pressed and unrefined from organic Nigella sativa seed, then every batch goes to an accredited lab for identity, heavy metals and microbial counts. The certificate ships with the jar.

The grade the kitchens pay for, in a softgel.
Single ingredientOil. Softgel. That is the list.
No proprietary blend, no fillers you have to look up.
Softgel, not spoonNone of the taste, all of the oil
Black seed oil is bitter and peppery by the spoon. A softgel is not.
Honest timelineGive it the trial window
Published trials ran eight to twelve weeks. Judge it there.
What actually happens
Not a feeling. A routine.
Black seed oil is not a stimulant. Here is what people report, and what the trials measured, in order.
Your first softgel.
Nothing to notice yet, and that is expected. Two softgels before bed; the routine starts, the oil does its work quietly.
The quiet weeks.
This is where most routines stall, because nothing tells you to wait. Customers most often report easier digestion and fewer colds around here. Reports, not promises.
The window the trials measured.
Randomized trials of Nigella sativa ran eight to twelve weeks before measuring markers of metabolic and inflammatory balance. Judge it at week twelve, not day two.*
01 / 04
The mechanism · 1 of 4
Two softgels. 800 mg.
Cold-pressed Nigella sativa oil, the only ingredient in the jar. The amount on the label is the amount in every serving.
The mechanism · 2 of 4
It opens in the gut.
The softgel dissolves after you swallow it, and the oil is absorbed like the other fats in your diet.
The mechanism · 3 of 4
Thymoquinone and the fatty acids.
Thymoquinone is the seed’s signature compound. It travels with omega-3, 6 and 9 fatty acids and the seed’s own antioxidants.
The mechanism · 4 of 4
Studied in trials, not in a feeling.
Randomized trials of Nigella sativa measured markers of metabolic and inflammatory balance over eight to twelve weeks. The evidence section grades each one.*

What the research supports
Evidence, graded without shortcuts.
Every claim sits next to the strength of the evidence behind it. Black seed oil has a real trial record; it also has a marketing record we do not repeat.
4 claims, graded one by one.1 strong1 emerging1 early1 not established
Nigella sativa supports healthy blood lipid and glucose levels already within the normal range.*Strong
Meta-analyses of randomized trials, mostly 1 to 3 g of seed or oil a day over 8 to 12 weeks. Figures to confirm before launch.
Supports a healthy inflammatory response.*Emerging
Smaller trials measured inflammatory markers; results point one way but samples are small.
Hair, skin and immune outcomes.Early
Mostly traditional use and single small studies. We list them as early, not proven.
Cures, detoxes or reverses anything.Not established
No. Black seed oil is a food oil in a softgel, not a treatment. We do not claim it.
Strong: replicated in more than one randomized trialEmerging: smaller, shorter or mixed human dataEarly: a single trial or a different doseNot established: no meaningful human evidence
- Meta-analyses of randomized trials of Nigella sativa on blood lipids, fasting glucose and blood pressure (2016 to 2021). Citations to be completed before launch.
- Randomized trials of Nigella sativa oil on markers of inflammatory balance (CRP, IL-6) in adults.
- Thymoquinone content varies by seed origin and pressing; our certificate reports the figure for each batch.
The difference
Not all black seed oil is labelled equally.

Questions.
Black seed oil by the spoon is bitter, peppery and easy to skip. A softgel carries the same cold-pressed oil with no taste and an exact dose. Two a day, preferably before bed.
Cold-pressed: the seed is pressed without heat. Unrefined: the oil is not bleached, deodorised or filtered beyond settling. Extra virgin: first press only. Together they keep the seed’s own compounds, including thymoquinone, in the oil.
Printed on the base of the jar. Enter it on the Verify page to open the certificate for your batch.
Yes. Black seed oil is a food oil. Keep your NMN and Glycine + NAC routine as it is and take the two softgels before bed. If you take prescription medication, are pregnant or nursing, ask your physician first.
