Calcium carbonate as an ingredient in dietary supplements, supplements rich in calcium and aids in the prevention of calcium deficiency, thereby enhancing bone health and lowering the odds of developing osteoporosis.
Antacids
Calcium carbonate is mostly found in pharmaceuticals, in fact, the several uses of intragastric calcium carbonate would probably include an antacid. It neutralizes acid in the stomach, thus alleviating common conditions like heartburn, acid reflux, and indigestion.
Excipient in Tablets
Calcium carbonate is an excipient as well in preparing tablets. It maintains the stability of the active ingredients and increases the compressibility of the tablets, and thus the overall effectiveness.
4. Agriculture and Animal Feed
The properties of calcium carbonate have made it highly beneficial in agriculture and animal husbandry because it improves the quality of soils and promotes livestock health.
Soil Conditioning
Calcium carbonate is widely used to condition soils. It is important to note that acidic soils are amended with calcium carbonate and that this increases their fertility coefficient and nutrient availability, thus enabling more healthful crops and yield increase.
Animal Feed Supplement
Also, calcium carbonate is added to animal feed as it provides essential calcium in livestock farming for bone-built development and health. It is particularly vital for poultry and dairy animals.
Fertilizer Component
CaCO3 is also an ingredient of fertilizers that enhances the effectiveness of these fertilizers in supporting nutrient availability and soil structure improvement. Thus, its use favors sustainable agriculture.
