Sourcing and qualification
- Thymoquinone is volatile and sensitive to light and heat. Keep the powder sealed, cool and dark, and consider a retest if material is held for long before use.
- This is a powder extract standardised by HPLC. It is different from cold-pressed black seed oil, where thymoquinone content varies widely between lots.
- The batch sits just above specification (3.08% vs 3.0%), so build any label claim on 3.0% and allow for storage losses.
