Vitamin K &D from Natural Factors provides two major fat-soluble vitamins for bone and vascular health: bioactive and highly bioavailable D3 (cholecalciferol), and menaquinone-7 (MK-7) from natto beans. Both vitamins act on calcium and guide the mineral toward where it is needed throughout the body.
Vitamin K &D from Natural Factors features vitamin K2 as menaquinone-7 (MK-7), an advanced, fat-soluble form of vitamin K that serves multiple functions in the body. Vitamin K2 plays a critical role in protecting the heart, as well as in building strong bones. As a director of calcium, vitamin K2 guides the mineral toward tissues where it is needed, such as bones, and away from tissues where it could have a negative effect, such as arteries. The highly bioavailable MK-7 from natto beans is the only form of K2 that offers 24-hour protection in a single daily dose. Other commercially available subtypes of K2, such as MK-4, only last four to six hours in the body and are required in much larger dosages to be effective.
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 helps 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.
Vitamin K &D from Natural Factors provides the ideal ratio of two major fat-soluble vitamins for overall health and support of bones and vascular health.
Combining vitamins D and K may provide even better support than the individual nutrients for bone and teeth development, and vascular health. Contains the bioactive and highly bioavailable D3 and MK-7 forms.
