Hydrochloric acid

Hydrochloric acid (also called HCL, HCL acid or betaine hydrochloride in supplement form) is considered one of the most important fluids (or “juices”) found in the human body. HCL is found inside the stomach and needed for many processes involved in digestive health. Unfortunately as you age, your production of hydrochloric acid decreases — which can increase gastrointestinal issues like heartburn, bloating and poor nutrient absorption.
