Calcitriol + Calcium Carbonate + Zinc + Magnesium + Vitamin K2-7 + Methylcobalamin + L-Methyl Folate is a combination of seven medicines : Calcitriol, Calcium Carbonate, Zinc, Magnesium, Vitamin K2-7, Methylcobalamin, and L-Methyl Folate. Calcitriol is the active form of Vitamin D. It raises Vitamin D levels in your blood. This in turn raises calcium levels in your blood by helping you absorb more calcium from your intestine. Calcium carbonate is a dietary supplement used when the amount of calcium taken in the diet is not enough. Zinc is a nutritional supplement that provides essential nutrients to our body and improves overall health. Magnesium is an antacid that neutralizes the excessive acid in the stomach. Vitamin K2-7 plays a central role in the metabolism of calcium, the main mineral found in your bones and teeth. Vitamin K2-7 activates the calcium-binding actions of two proteins: matrix GLA protein and osteocalcin, which help to build and maintain bone health.
