Ageing is accompanied by a gradual weakening of important organic functions such as the function of the stomach. During aging, the production of hydrochloric acid often decreases, remaining at relatively sufficient levels for the breakdown of food but weakening, for example, in its ability to sterilize food after ingestion, and to activate a powerful protease called pepsin which contributes to the absorption of Vitamin B12. After leaving the stomach, the food enters the small intestine, where it is further broken down into individual nutrients. This specific dietary supplement contributes to the restoration of reduced stomach acidity and better digestion of food in people who wish to restore the adequacy of hydrochloric acid.
