PDA supplements the body's digestive secretions with hydrochloric acid (HCl) and provides pepsin, a natural protein-digesting enzyme. The stomach manufactures hydrochloric acid to break down proteins. But, as people age, they may produce less HCl, which can affect the amount of protein they can break down and ultimately absorb. Inefficient protein digestion can affect the viability of the intestinal flora that feast on these compounds.
Betaine hydrochloric acid, pepsin.
