WebThe enzymes that help digest food in the stomach, such as pepsin, work best at a pH around 2, while those that function in the intestines, including peptidases and maltase, work best at a pH around 7.5. Considerations Antacids increase the pH in the stomach, which might make the enzymes in the stomach less effective. WebBetaine HCl & Pepsin promotes optimal stomach acidity, protein digestion, and enzyme activity. Indigestion can be caused by many things – including inadequate amounts of hydrochloric acid (HCl) in the stomach. HCl secretion in the stomach does several positive things. It assists protein digestion by activating pepsinogen to pepsin, it renders ...
