How to use Bonultra Tablet

Take this medicine in the dose and duration as advised by your doctor. Swallow it as a whole. Do not chew, crush or break it. Bonultra Tablet may be taken with or without food.

How Bonultra Tablet works

Bonultra Tablet is a combination of three medicines : Calcitriol, Calcium Citrate Malate, and Vitamin K2-7. 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, and is used when the amount of calcium taken in the diet is not enough. 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.
