K2 and D3 vitamins are fat-soluble nutrients that play an important role in calcium metabolism.
While their roles are distinct, they overlap.
D3 vitamins are best known for helping the body absorb calcium—a mineral essential for muscle function, nerve transmission, blood vessel constriction, and vasodilation, as well as intracellular hormone secretion and bone resorption and deposition.
Vitamin K2 also plays a role in regulating bone metabolism, since calcium utilization depends on the synthesis of vitamin K-dependent proteins.
Without this dynamic duo, calcium would not be adequately utilized for healthy bones and teeth.
