Certificate of Analysis — Lab-Tested Black Seed Oil

What Is a Certificate of Analysis?

A Certificate of Analysis (COA) is a document issued by an independent laboratory confirming the composition, purity, and quality of a product based on analytical testing of a specific production batch. For black seed oil, a COA provides objective data on what is actually in the bottle — not just what the label claims.

Unlike testing done in-house by the brand or supplier, a third-party COA comes from a laboratory with no financial relationship to the seller. The results are independent — there is no incentive to inflate numbers or overlook quality concerns. ThymoCura™ uses accredited laboratories that follow recognized testing methodologies for botanical oils.

What Our COA Helps Verify

Each ThymoCura™ Certificate of Analysis covers the following test categories for the specific production batch:

Why Batch-Specific Testing Matters

Many supplement products display a “lab tested” badge that refers to a one-time historical test, a test of a different production lot, or internal brand testing rather than independent verification. A batch-specific COA is meaningfully different because it connects test results directly to the production run you are actually receiving.

When you order ThymoCura™ black seed oil, the COA corresponds to your specific bottle’s batch — not a generic reference sample from a prior lot. Batch results can vary as seed harvests and production runs change, which is why ongoing per-batch testing provides more useful assurance than a single historical certificate.

Understanding 2.34% TQ

TQ stands for thymoquinone, a naturally occurring compound found in Nigella sativa oil. It is one of the primary markers used to assess the potency and quality of black seed oil, and a disclosed TQ percentage gives customers a concrete, measurable reference rather than subjective quality language.

ThymoCura™’s current batch is verified at 2.34% thymoquinone. This means the TQ content was actually measured by an independent laboratory and documented — not assumed, estimated, or described with marketing language alone.

Why Third-Party Testing Matters

In the black seed oil market, quality varies significantly between products. Some oils are diluted with carrier oils, extracted using chemical solvents, or sourced from seeds of inconsistent quality. Without independent verification, there is no reliable way to confirm what is actually in a bottle.

Third-party testing removes that uncertainty. The laboratory issuing our COA has no financial stake in the results — they test what we send them and report what they find. That independence is the difference between a verified claim and an unverified marketing statement.

Our cold-pressed extraction process uses no heat or chemical solvents, which helps preserve the oil’s natural profile. Third-party lab testing then confirms the results of that process with documented, objective data per batch.

How to Request a COA

A current batch COA can be provided on request. We do not currently offer a public downloadable PDF on this page — documentation is issued on a per-batch basis so the COA you receive matches the actual production lot in your bottle.
