In the stomach, it acts as a local antacid, behaving as a base and thus neutralizing hydrochloric acid. Its effects are slow but prolonged. In the intestine, and in sufficient amounts, it acts as a gentle laxative, transforming in the stomach into magnesium chloride, a non-absorbable salt, which, by osmosis, improves intestinal transit. Magnesium carbonate usually takes effect 4-12 hours after ingestion, without causing cramps or irritations. As a source of magnesium, in the intestine the release of magnesium ions occurs, which are absorbed by the intestinal wall and pass into the blood. Magnesium is a cation that acts mainly in bones. Magnesium carbonate is beneficial for bones as it is necessary for the absorption of calcium. In the skeletal and nervous systems, magnesium is part of the coenzymes necessary for the conversion of ATP to ADP, necessary for the proper functioning of muscles and nerves.
