An important fat-soluble vitamin, vitamin K2, plays critical roles in protecting the heart and brain, as well as building strong bones. As a director of calcium, vitamin K2 guides the mineral towards tissues where it is needed, such as in bones, and away from tissues where it could have a negative effect, such as arteries.
Natural Factors vitamin K2 is highly bioavailable menaquinone-7 (MK-7) from the natto bean, which offers 24-hour benefits from a single daily dose.
Vitamin D is also a fat-soluble vitamin that is essential for calcium absorption, playing an important role in the growth and maintenance of healthy bones and teeth. Ongoing and current research outlines the importance of vitamin D in the prevention of osteoporosis. It aids calcium absorption from the intestines, reduces calcium excretion, and facilitates calcium incorporation into the bones.
Vitamin D3 (cholecalciferol) is the safe, natural, and more biologically active form of vitamin D. Natural Factors K & D provides the ideal ratio of two major fat-soluble vitamins for overall health, and support of bones and vascular health.
