Protease: Nature's Protein-Digesting Enzyme That Survives the Stomach's Acidic Environment
Protein is only useful if the body can properly digest it. This article explains how protease—an acid-stable enzyme that survives the stomach’s harsh environment—breaks dietary proteins into absorbable amino acids essential for growth, immunity, and tissue repair. It reviews emerging evidence showing that supplemental proteases can enhance amino acid availability, particularly during critical growth windows and with plant-based proteins. The post also explains why HolistIQ includes acid-stable protease to support efficient protein digestion in children aged 2–9 years.
