Immune support

One teaspoon. For the immune system you already have.

One cold-pressed seed your body already knows — Ethiopian, single-origin, kept on kitchen shelves for fourteen hundred years. Studied to support a healthy, balanced inflammatory response.

The science

From tradition to measurable biomarkers.

The research on Nigella sativa and immune function has moved from tradition to measurable biomarkers — T-cell populations, immunoglobulins, inflammatory markers — in controlled human trials.

A 2023 randomized, double-blind, placebo-controlled trial (n=52)

This trial used encapsulated seed mass, not cold-pressed oil — included here to characterize the active-compound research base, not as evidence of habb’s effect. Healthy young adults studied Nigella sativa at 0.5g, 1g, and 2g per day over four weeks. At the 1g/day dose, total lymphocytes rose from 1,850 ± 0.24 × 10³/μL to 2,170 ± 0.26 × 10³/μL (p=0.008). CD3+ T-lymphocytes moved from 1,184 to 1,424 cells/μL (p=0.009). CD4+ T-helper cells moved from 665 to 841 cells/μL (p=0.002). No adverse effects at any dose.1

A 2023 meta-analysis of 20 randomized controlled trials (n=1,086)

Synthesized the inflammation data. Nigella sativa supplementation was associated with significantly reduced C-reactive protein (CRP; SMD = −2.28; 95% CI −3.20 to −1.37; p<0.001), TNF-α (SMD = −1.21; p=0.013), and MDA (SMD = −2.15; p<0.001), and with significantly higher total antioxidant capacity.2

habb is not a stimulant for your immune system. It supports normal T-cell activity and a healthy, balanced inflammatory response — the upstream conditions a healthy immune system runs on.

Why one ingredient, not twelve

The active compound is what every study measures.

We show its number on the card. The number on your bottle should be the real one.

Every habb batch publishes three data points on the batch card:

Thymoquinone — HPLC-UV on the fixed oil, minimum 2%

Lab-verified by an independent third-party lab. We use the conservative test, not the inflated one. The card shows the method.

Fatty acid profile (GC)

Linoleic 57–61%, oleic 20–21%, palmitic 12–13%. If a bottle won’t show you what’s in it, that’s the answer.

Benzo(a)pyrene under 2.0 μg/kg

For oxidation and contamination safety.

Sourcing: Ethiopian seeds, cold-pressed in California, one ingredient. The full how-it’s-made math lives on how it’s made.

How to use

One teaspoon, every morning.

The ceramic spoon ships with every bottle and holds the exact daily serving.

Take it straight, in warm water with honey, or stirred into a morning drink. The 1g/day dose in the T-cell trial is roughly one teaspoon of cold-pressed oil. Consistency — every morning, same time — is how the biomarkers in those trials moved.

Questions

The honest answers.

Is habb a "booster"?
No. habb is a daily food, not a prescription. We don’t use booster language. The seed has a long food-use history, and the research on Nigella sativa describes support for a healthy, balanced inflammatory response — your experience depends on your baseline and the rest of your routine.
How does habb compare to elderberry or vitamin C?
Different category. Elderberry and vitamin C are antioxidants with their own evidence base. Nigella sativa has been studied specifically for its effect on T-cell populations, immunoglobulins, and systemic inflammatory markers in controlled human trials. Some customers take both.
Can I take habb year-round?
Yes. Nigella sativa has a long food-use history and GRAS status under 21 CFR 182.10. The clinical trials ran 4 weeks to 90 days without reported adverse effects at typical food-use doses. That said, if you have a medical condition or take prescription medication, ask your healthcare provider first.
What dose is in one teaspoon of habb?
Approximately 4.5g of oil, which delivers ≥90mg of thymoquinone at our 2% HPLC-UV minimum. The 1g/day and 2g/day doses in the clinical trials refer to seed mass or capsule mass; our cold-pressed oil form is a different vehicle at a comparable daily intake.
Is there a vegan or allergen concern?
habb is one ingredient: cold-pressed Nigella sativa oil. No gelatin, no fillers, no common allergens (not a tree nut, not a peanut). Halal and vegan by nature.
