Protease is a type of enzyme that is responsible for breaking down protein molecules into smaller peptides and amino acids. It is naturally produced in the body and is also found in many foods, including meat, eggs, and dairy products.
In protein powders, protease may be added as an ingredient to help improve the digestion and absorption of protein. It works by breaking down the long protein chains into smaller peptides and amino acids, which can be more easily absorbed by the body.
Protease is generally considered safe when used in recommended amounts.
