500 mg & 200 IU: Each film-coated tablet contains Calcium Carbonate BP (eggshell source) 1250 mg equivalent to 500 mg of elemental Calcium and Cholecalciferol (Vitamin D3) BP 200 IU.

600 mg & 400 IU: Each film-coated tablet contains Calcium Carbonate BP (eggshell source) 1500 mg equivalent to 600 mg of elemental Calcium and Cholecalciferol (Vitamin D3) BP 400 IU.


This is the combination of Calcium Carbonate and Vitamin D3, where Calcium is obtained from European eggshell source. Along with Calcium it contains small amounts of essential salts and minerals for bone development, including Magnesium, Phosphorus & Strontium. It is 100% natural, highly digestible (98%), more absorbable and environment-friendly form of Calcium. It enriches the organic matrix of bones by helping the fixation of Calcium and increases bone density. It also contains soluble transport proteins for maximum absorption compared with other Calcium sources. Its absorption rate is higher than that of Algae, Coral, or Rock-based Calcium.


Calcium plays a very important role in the body. It is necessary for normal functioning of bone, nerve cells, muscle, and other vital organs and the regulatory system of the body. If there is not enough calcium in the blood, then the body will take Calcium from bones, thereby weakening bones and triggers different types of bone disorder. Vitamin D3 helps the body to absorb Calcium. Having the right amounts of Calcium and Vitamin D3 is important for building and keeping strong bones and healthy muscles.
