Black seed has been used for centuries due to its nutrient-rich properties. Because of its trusted reputation, Solaray is pleased to add our own black seed to our line of powerful health supplements, Cold Pressed Black Seed 7% Thymoquinone. Black seed, or Nigella sativa, is believed to offer a wide range of health benefits, including supporting healthy circulation, supporting healthy digestion, and supporting healthy immune function. Many of the black seed's purported health benefits are because it is rich in nutrients such as the phytochemical compound thymoquinone. These powerful nutrients can also support joint comfort, respiratory health, and vitality. Solaray Cold Pressed Black Seed produces a phytoactive potency of 7% Thymoquinone or 64 mg per serving. Solaray Black Seed drops are lab verified for potency, purity, and identity. Cold pressed black seed with 7% thymoquinone simply works better to make it shine brighter.
