How to use Calsure Capsule

Take this medicine in the dose and duration as advised by your doctor. Calsure OS Capsule may be taken with or without food.

How Calsure Capsule works

Calsure OS Capsule is a combination of four medicines : Calcitriol, Calcium Citrate Malate, Vitamin K2-7, and Zinc Oxide. 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 citrate malate is a water-soluble calcium supplement. It increases the plasma calcium levels. 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. Zinc oxide is a necessary trace element in the diet, forming an essential part of many enzymes, and playing an important role in protein synthesis and in cell division.
