Vitamin D3 is a natural partner of vitamin K2. The vitamin D3’s function is to enhance calcium absorption. But excessive calcium in the wrong places can cause disease. The combination of vitamins D-3 and K2 does not cause coagulation. Vitamin K2, through a chemical step called carboxylation regulates and balances the coagulation system as a whole. Carboxylation of osteocalcin is done by vitamin K to maintain bones properly mineralized. Activated osteocalcin also stimulates adiponectin, a potent fat metabolism stimulator which helps people maintain normal weight. Finally, evidence demonstrates that vitamin D3 and K2 play an important role in bone and cardiovascular health and have the ability to support the brain function, a healthy skin and to reduce cancer risk among other benefits.
