Vitamin D contributes to the normal absorption and utilization of calcium and phosphorus, and to the maintenance of normal bones and muscle function. It contributes to the normal function of the immune system. Vitamin K contributes to the maintenance of normal bones. Vitamin D3 (cholecalciferol) plays a very important role in calcium and phosphorus homeostasis and metabolism, regulating their concentrations in the blood, promoting normal bone trophism, and also intervening in cell division processes. Vitamin D also has other biological effects, including an important role in various neuromuscular and immune functions. The action of regulating blood calcium levels by vitamin D contributes to the maintenance of normal muscle function, as calcium is a fundamental mineral for proper muscle contraction. Vitamin K2 is fat-soluble and ensures the proper function of certain proteins, particularly osteocalcin, which builds and maintains strong bones. Osteocalcin (or GLA bone protein), activated by vitamin K2, regulates the incorporation of calcium phosphate into bones. It is recommended to take up to 3 sprays per day, directly into the mouth.
