Maycal-K2 Softgels is a combination of seven medicines: calcitriol, calcium carbonate, 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 intestines. Calcium carbonate is a supplement that helps when your diet doesn’t provide enough calcium. 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 build and maintain bone health. Methylcobalamin is a form of vitamin B12 that restores its level in the body, thereby helping in treating certain anemias and nerve problems. L-methyl folate is the primary biologically active isomer of folic acid and the primary form of folate in circulation. Folic acid is a form of vitamin B. It is essential for the production of red blood cells, which transport oxygen throughout the body.
