Black cumin seed oil (Nigella sativa), used across the Middle East, North Africa and South Asia for well over a thousand years. Its signature active compound is thymoquinone, alongside a profile of unsaturated fatty acids. The oil on its own is famously sharp and bitter; the softgel format delivers it without the taste. A traditional wellness staple that has moved firmly into the modern supplement cabinet. Two softgels a day, 30 servings per bottle.
