A human consumable chemical compound of calcium carbonate which is coated with an impervious coating that will not allow the compound to dissolve from stomach acid but does allow it to dissolve in the aqueous environment of the intestine. The chemical compound is time released, and is positionally sensitive to reach the intestines of the human body where it is absorbed into the blood. Carbonic acid in the blood reacts upon the gradual dissolution of the compound and this reaction converts the calcium carbonate to calcium bicarbonate. Calcium bicarbonate in the blood neutralizes the bodys harmful acidic wastes and is a substitute for drinking about fifty ounces of alkaline drinking water daily.
