Vitamin K1 (phylloquinone) is a fat-soluble vitamin necessary for the formation of prothrombin, which is required for normal blood clotting.* It also plays a role in bone formation and healthy liver function, and may help maintain female reproductive health.* In a double-blind, placebo-controlled trial of 181 post-menopausal women, vitamin K significantly enhanced the effectiveness of supplementation with calcium, vitamin D, and magnesium.
