Calcium Sandoz®+Vitamin C Effervescent Tablet works as a source of calcium and vitamin C. Calcium is the most abundant mineral in the body; the major portion is in the bone. Calcium plays an important role in the way the body functions. It is essential for nerve, muscle and heart functions as well as for clotting of blood. In addition, it mediates the action of many hormones. To carry out these various roles, calcium must be available to the appropriate tissues in the proper concentration. The vitamin C plays an important role in biochemical processes. It is also needed for collagen formation and tissue repair.
