Active ingredients in A12AA

Active Ingredient Description
Calcium carbonate

Calcium carbonate releases, in a pH-dependent manner, calcium ions in the stomach. Calcium carbonate is widely used as antacid and extensively used as a dietary supplement.

Calcium chloride

Calcium is the most abundant mineral in the body, and is an essential body electrolyte. Homeostasis is mainly regulated by the parathyroid hormone, by calcitonin, and by the activated form of vitamin D. Calcium is a structural component of bones and teeth. It is also required for blood clotting, neurotransmitter release, muscle contraction and normal heartbeat.

Calcium citrate
Calcium gluconate

Calcium gluconate is the gluconate salt of calcium. An element or mineral necessary for normal nerve, muscle, and cardiac function, calcium as the gluconate salt helps to maintain calcium balance and prevent bone loss when taken orally.

Calcium glycerophosphate
Calcium lactate

Calcium lactate is used as an antacid and in calcium deficiency to treat hypocalcaemia. It can be absorbed at various pHs, thus it does not need to be taken with food. Calcium lactate is an antidote for soluble fluoride ingestion16: p165  and hydrofluoric acid.
