Black Seed Oil COA & Thymoquinone Testing
We provide a Certificate of Analysis (COA) with every batch. Our commitment is to consistent quality, transparent documentation, and reliable supply from trusted sources.
What Our COA Covers
Each production batch is accompanied by a Certificate of Analysis documenting key quality parameters:
- Thymoquinone (TQ) content — verified at 1.2-2.4% for standard oil, up to 3% for High TQ
- Fatty acid profile — oleic, linoleic, palmitic, stearic acid percentages
- Batch identification — production date, batch number, and expiration date
- Physical properties — color, odor, specific gravity, and refractive index
Typical Fatty Acid Profile
Each batch of our cold-pressed black seed oil is analyzed by GC-MS for fatty acid composition. Typical ranges across recent production batches:
Exact values vary naturally by harvest and batch; each batch's analysis report states its specific composition and is available on request.
