Inadequate calcium intake can lead to decreased bone mineral density, which can increase the risk of bone fractures. Supplemental calcium promotes bone mineral density and strength and can prevent osteoporosis (ie, porous bones), particularly in older adults and postmenopausal women.However, recent scientific evidence suggests that elevated consumption of calcium supplements can raise the risk for heart disease and can be connected to accelerated deposit of calcium in blood vessel walls and soft tissues.
In contrast, vitamin K2 is associated with the inhibition of arterial calcification and arterial stiffening, which means that increased vitamin K2 intake could be a means of lowering calcium-associated health risks. However, since 1950, the consumption of vitamin K has decreased gradually, and even a well-balanced diet might not provide vitamin K in amounts sufficient for satisfying the body’s needs.
Further, due to modern manufacturing processes, the vitamin K content, particularly the vitamin K2 content, of the food supply today has significantly dropped, making vitamin K2 supplements a more reliable way to secure adequate intake. By striking the right balance in intake of calcium and K2, it may be possible to fight osteoporosis and simultaneously prevent the calcification and stiffening of the arteries. A new clinical study with vitamin K2supplementation showed an improvement in arterial elasticity and regression in age-related arterial stiffening (data pending publication). Most important, through its activation of K–dependent proteins, vitamin K2 can optimize calcium use in the body, preventing any potential negative health impacts associated with increased calcium intake.
