| Applications | Nutraceutical and dietary-supplement raw-material manufacturing — thymoquinone is the primary studied bioactive constituent of black seed oil, a widely sold botanical supplement ingredient |
Thymoquinone is a substituted benzoquinone that occurs naturally in Nigella sativa (black seed/black cumin) seed oil, where it’s considered the primary bioactive marker compound. It has been the subject of extensive preclinical pharmacological research, though it is not an FDA-approved drug for any indication.
This compound is used as a raw-material ingredient in nutraceutical and dietary-supplement manufacturing (standardized black-seed-oil-derived ingredients), and as a research compound in preclinical pharmacology studies.
Compliance note: This is a bulk research/raw-material chemical, not a finished, approved dietary supplement or drug product. Any supplement-manufacturer customers are responsible for ensuring their own finished-product claims comply with FDA dietary-supplement regulations (DSHEA) — thymoquinone/black-seed-oil products should not be marketed with disease-diagnosis, -treatment, -cure, or -prevention claims without appropriate regulatory support.
