Calcium D3 Forte is a food supplement in the form of film-coated tablets that contain a high dose of calcium and vitamin D - ingredients that help maintain the health of bones and teeth. Calcium plays an important role in maintaining proper neurotransmission and contributes to proper blood clotting. Vitamin D supports the proper absorption and use of calcium and phosphorus, as well as the maintenance of adequate blood calcium levels.
