About this ingredient
Ingredients
Protease is a protein-digesting enzyme that breaks down proteins by hydrolyzing peptide bonds, producing smaller peptides and amino acids. Proteases used in supplements may come from microbial, plant, or animal sources, including enzymes such as bromelain, papain, pepsin, and microbial proteases. The exact source, enzyme activity, concentration, and formulation vary by manufacturer.
Protease is an enzyme involved in the digestion of dietary proteins. It hydrolyzes peptide bonds within proteins and peptides, helping convert larger protein molecules into smaller peptides and amino acids that can be further processed and absorbed. (ncbi.nlm.nih.gov)
Protein digestion naturally involves several proteolytic enzymes. Pepsin begins protein digestion in the stomach, while pancreatic proteases such as trypsin, chymotrypsin, elastase, and carboxypeptidases contribute to protein digestion in the small intestine. (ncbi.nlm.nih.gov)
Commercial protease supplements may use enzymes from different sources. Bromelain is derived from pineapple, papain from papaya, and some commercial proteases are produced through microbial fermentation. Different proteases have different activity characteristics and may function under different pH and temperature conditions.
Protease is commonly included in digestive enzyme supplements, multi-enzyme blends, protein-focused nutritional products, and sports-nutrition formulations. Enzyme activity is generally expressed using specific activity units, so activity information can be more useful than the weight of the enzyme ingredient alone when comparing products.
Because protease products vary significantly, consumers should check the label for the enzyme source, activity units, amount per serving, serving instructions, and additional digestive enzymes.
