CALCIUM CARBONATE + VITAMIN D3

Description: Calcium carbonate is a calcium supplement that is used in deficiency states and as an adjunct in the prevention and treatment of osteoporosis. Vitamin D3 is a fat-soluble sterol, it balance calcium and phosphate in the blood and bone mineralization.

This combination medication is used to prevent or treat low blood calcium levels due to people’s diets. Such low blood calcium level conditions as bone loss (osteoporosis), weak bones (osteomalacia/rickets), decreased activity of the parathyroid gland (hypoparathyroidism), and a certain muscle disease (latent tetany). Calcium is necessary for normal functioning of nerves, cells, muscle, and bone. If there is not enough calcium in the blood, then the body will take calcium from bones, thereby weakening bones. Vitamin D helps your body absorb calcium and phosphorus.
