Get double the power with this double-strength version of Swanson K2, delivering 100 mcg of vitamin K2. Swanson K2 (formerly Natto K7) is the most biologically active form of vitamin K2. While vitamin K is mostly known for its involvement in blood clotting, K2 also helps to activate the osteocalcin and matrix GLA proteins that regulate where calcium ends up in the body.
Vitamin K2 itself consists of 13 numbered natural substances called menaquinones of which primarily menaquinone-7 has been scientifically studied to benefit cardiovascular and bone health. Studies suggest menaquinone-7 specifically may also support both mood and blood sugar health in women.
Extensive research completed in the Netherlands indicates the natto-derived form of menaquinone-7 helps get calcium out of the arteries and into the bones where it belongs. This promotes bone formation and strength as well as vascular health.
Swanson Vitamin K2 is derived from natto, a fermented soy product that is the richest natural source of K2, and delivers menaquinone-7 in sunflower seed oil-based softgels for better absorbability.
