What's in the bottle

Most of what's on the supplement aisle, you have to take on faith.

The wellness aisle runs on label trust. We'd rather you not need any. Every habb bottle ships with the lab numbers for that specific batch — printed on a card, with the test methodology below.

The artifact

This ships in every box.

Filled in per batch. Traceable by lot. The card answers the question every label-reader has been quietly asking about everything in the cabinet.

habb · Certificate of Analysis BATCH [LOT] · representative example

Thymoquinone (TQ) The active compound. Measured per batch.

HPLC-UV · fixed oil

p-Cymene Adulteration check. Absent in canola, soy, palm, sunflower, corn.

GC method

Fatty acid profile The seed's fingerprint. Cuts shift the ratios.

Linoleic / Oleic / Palmitic

Benzo(a)pyrene Heat-extraction byproduct. Low number = cold-pressed.

< 2.0 μg/kg

Peroxide value (PV) Oxidation indicator at point of shipment.

meq O₂/kg

Acid value (AV) Second freshness check.

mg KOH/g

Harvest-to-bottle Date-to-date. Printed alongside best-by.

You don't have to read them. They're yours if you want to.

Why this matters

Same bottle. Wildly different numbers.

263×

difference in thymoquinone content across eleven commercial black seed oil products tested in 2022. The same category. The same ingredient. Nutrients · 2022 · PMC9460610

1× 263×

The industry is allowed to pick its method, pick its moment to test, and pick what to print.

2 of 7 retail black seed oil brands tested in January 2025 failed to meet their own thymoquinone label claim. One came in at 41.8% of label; another at 66.6%. ConsumerLab · January 2025

Why our number looks smaller

Two methods. Same bottle. Wildly different numbers.

habb's method

HPLC-UV · fixed oil

What's in the oil you swallow.

1.5 – 4.6%

Real Ethiopian cold-pressed black seed oil tests in this range. The number is what your body actually receives.

GC-MS · volatile fraction

What evaporates if you heat the oil.

22 – 35%

Same bottle. Different lab method. The number is real, but it doesn't reflect what you ingest.

Both tests are real. Both labs give you a certificate. Only one of them reflects what's in the oil you're about to swallow.

Where the seed comes from

Bale and Arsi highlands, Ethiopia.

Volcanic soil. 2,200 to 2,800 metres above sea level. Cold nights, intense ultraviolet, mineral-rich earth. The conditions that stress Nigella sativa into producing more of what makes it functional.

Cold-pressed and bottled in California in a US FDA-registered, cGMP-compliant facility. Halal- and OU Kosher-certified.

Why Ethiopian highland seed runs roughly 4× higher in active compound →

Region: Bale & Arsi, Oromia
Altitude: 2,200 – 2,800 m
Press temp: ≤ 60°C, no solvents
Harvest-to-counter: under 6 months

Look up your batch

Enter the lot number from your bottle.

Each batch has its report on file, looked up by the lot number on the bottle. If a friend hands you a habb bottle and you want to see what's in it, the report's here.

Real reviews. No AI.

The supplement aisle is full of AI-touched reviews. We won't be.

Most wellness reviews today are AI-generated, AI-summarized, or AI-padded. The line between real and synthetic is invisible to the buyer. We commit to a different standard.

Verified purchasers only

Reviews are tied to a real order and lot number. If you didn't buy the bottle, you can't review it.

ii.

Customer's own words

No AI rewriting, summarizing, or padding. We don't run reviews through a model to make them sound better.

iii.

Paid placements disclosed

Creator, ambassador, gifted bottle — the FTC tag goes on the review itself, not buried in a footer.

iv.

Negative reviews stay

If the oil isn't for you, that's information other buyers deserve. We respond in public.

No reviews for ghost products

If a habb product is mentioned in a review, the product is in the catalog and you can actually buy it.

If we ever break one of these rules, call it out. Email hello@habb.co with the review URL — we'll respond in public.

Questions

What we get asked about this page.

The card

Why doesn't every supplement do this?

Batch-level testing costs more than annual testing. Publishing the real HPLC-UV number constrains what a brand can advertise elsewhere. And showing the full data means committing to doing the work every batch, not just the first one. Plenty of brands decide it's not worth it. We think it is.

What do I do with the numbers?

Nothing, if you don't want to. The point is they exist. If you read ingredient panels, you can now read a thymoquinone panel. If you want to verify a batch you bought 9 months ago, look it up at habb.co/coa/batch-[LOT]. The card answers the question every label-reader has been quietly asking about everything in the cabinet: "how do I know if mine is real?"

What if I lose my batch card?

The lot number is also printed on the bottle itself, near the manufacture and best-by dates. Look up habb.co/coa/batch-[LOT] anytime.

Can I request the full raw lab PDF?

Yes. The full report for each batch lives at habb.co/coa/batch-[LOT], linked from the batch lookup. If you need something the lookup doesn't cover, email us with the batch number.

Certifications

Is the batch card the same as halal certification?

Separate. habb is bottled in a halal- and OU Kosher-certified facility. The batch card is a different transparency mechanism — it tells you what's in the oil; certification tells you the ingredient list and facility meet dietary standards. Two different kinds of trust.

Reviews

How do I know habb's customer reviews are real?

Every review is from a verified habb purchaser tied to a real order and lot number. We don't AI-generate, AI-summarize, or AI-pad reviews. Paid placements (creators, ambassadors, gifted bottles) are disclosed inline. We don't delete negative reviews. We don't publish reviews for products that don't exist. Full five-point policy is in the section above.

It shouldn't be rare

The cabinet got crowded. The labels got longer. Verification got rarer.
This is what every supplement should come with.
