The bioavailability of inorganic mineral salts like sulphates, carbonates and oxides is very low. They are characterised by very low solubility, but if they do dissolve in the stomach they disassociate into a salt and the mineral (charged ion) and irritate the stomach wall or bind to other nutrients to form insoluble and unabsorbable compounds. An electrolytic imbalance is created that can lead to irritated bowels and reduced absorption of nutrients by the body. Selecting organic mineral salts that dissolve well, such as citrates, fumarates and glycerophosphates or chelates that do not disassociate in the stomach (such as bisglycinates) can result in optimal absorption.
