OriginCalcium acetate is derived from acetic acid and calcium compounds, typically produced synthetically. It is synthesized through the neutralization reaction of acetic acid with calcium carbonate or calcium hydroxide.
Calcium Acetate is a calcium salt of acetic acid. Calcium is a mineral essential for many cellular functions including nerve impulse transmission, muscle contraction, cardiac function, bone formation, and capillary and cell membrane permeability. Calcium acetate is administered orally to prevent or treat calcium deficiency and to treat hyperphosphatemia due to its phosphate-binding properties.
