Synergy
What is happening. Betaine HCL and digestive enzymes are commonly combined to support digestion, with the acidic environment from betaine HCL helping activate pepsin and optimize protein breakdown.
Mechanism. Pepsinogen requires an acidic pH to convert to active pepsin, so betaine HCL lowers gastric pH to support protein digestion, complementing pancreatic and plant-derived enzymes acting in the stomach and intestine.
Recommendation. Generally well tolerated together with meals. Reduce the dose or stop if heartburn or epigastric burning occurs, and avoid if you have active ulcers or take acid-suppressing medication.
