Australian NaturalCare Calcium + Vitamin D3 & K2 combines three key bone health nutrients to support the development and maintenance of strong healthy bones. Just 1 tablet twice daily provides you just the right amount of each element. Calcium is central to the structural integrity of bone matrix, thus improving bone density and strength. Vitamin D3 and K2 work together to direct calcium to your bones and to enhance calcium absorption. Vitamin D3 regulates your blood calcium levels. It does this by stimulating absorption through the intestine and its excretion through the kidneys. Low levels of vitamin D have been associated with muscle weakness, impaired balance and can also contribute to accelerated muscle mass and strength loss. Vitamin K2 activates osteocalcin, a protein found in bone which allows the binding of calcium. This not only assists in bone formation, strength and repair, but also works to improve cardiovascular health too. It helps maintain the elasticity of blood vessel walls. Calcium + Vitamin D3 & K2 may assist with: - Maintaining bone strength and density. - Supporting optimal bone strength throughout life. - Supporting cardiovascular system health. - The development and maintenance of strong healthy bones.
