- CalSource Ca-C1000 contains three active ingredients, two
are calcium salts (calcium lactate gluconate and calcium
carbonate) and the third is ascorbic acid (vitamin C).
– Calcium is an essential mineral, necessary for bone formation and
maintenance. Calcium also plays an important role in the way the
body functions. It is essential for nerve, muscle and heart function
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.
– Vitamin C plays an important role in biochemical processes.
It is also needed for collagen formation (found in bone,
cartilage, skin, and other tissues) and tissue repair.
– CalSource Ca-C1000 effervescent tablets provide vitamin C and
calcium in amounts sufficient to cover the daily needs at times of
increased requirements.
