BioCare HCI & Pepsin provides hydrochloric acid in the form of betaine hydrochloride and pepsin in order to aid digestion. Factors such as infections, colds, stress, hot foods, surgery and fevers can disrupt the natural acid production in the stomach. BioCare HCI & Pepsin then helps to recover this balance. HCI (Hydrachloric Acid) provides an inhibitory environment for potential unhealthy bacteria ingested through food. It also provides the ideal environment for pepsin activity. Pepsin hydrolyses (dissolves to water) all types of proteins reducing them to the easier digested polypeptides.
