Black Seed Oil Thymoquinone Content: How to Compare Brands
What TQ percentages mean, organic vs non-organic, and where to buy.
Key takeaways
- TQ content varies widely between oils.
- Look for third-party testing, not just a claimed number.
- Cold-pressed and organic are good quality signals.
What is TQ content?
Thymoquinone (TQ) is black seed oil's main active compound.[1] Cold-pressed oils commonly contain around 0.5–3% TQ; higher claims should be backed by lab tests.
How to compare
- Stated TQ % with a test certificate
- Cold-pressed, unrefined
- Organic certification
- Origin of seeds (e.g. Ethiopian)
- Dark glass bottle and expiry date
