Bromelain is a protein-digesting (proteolytic) enzyme mixture found naturally in the pineapple plant's stem, fruit, and juice. It can break down a variety of types of protein in both acid and alkaline environments. Bromelain assists the body in breaking down very large, complex protein molecules into smaller peptide units or individual amino acids. These smaller peptide units are crucial for the body's production of muscle tissue, neurotransmitters, and other protein-based molecules.

Papain is a powerful proteolytic enzyme commonly found in and extracted from the papaya fruit (Carica papaya) and papaya leaves and stems. It is also referred to as papaya proteinase. 

The papaya enzyme papain plays a key role in digestive processes involving the breaking down tough protein fibers. This powerhouse enzyme promotes a normal and speedy recovery from sports injuries and may ease muscle soreness. Papain also digests sinus mucin, a glycoprotein found in mucus, and hence may have beneficial effects for people suffering from congested nose and sinus issues. Papain makes mucus less viscous or runnier and hence better able to be eliminated.

Discovered in the early 1970s, this proteolytic enzyme was isolated from of bacteria located in thesilkworms' intestines of silkworms. This enzyme possesses a potent anti-inflammatory action, and research has shown profound benefits in the management ofmanaging pain and inflammation.

Serrapeptase demonstrates the ability to reduce capillary permeability,break down abnormal proteins,facilitate the absorption of decomposed products through the blood and lymphatics, and may regulate immune cell migration from the lymph nodes to inflamed and injured tissue.

Nattokinase is a powerful proteolytic enzyme and is best known for its benefits on cardiovascular health. Traditionally, nattokinase is extracted from natto, a fermented soybean dish from Japanese cuisine and culture. The organism producing nattokinase is made by a fermentation process incorporating the bacteria Bacillus subtilis. 

Nattokinase belongs to the group of serine protease enzymes that help reduce blood clotting. This fibrinolytic (anti-clotting) ability makes it an extremely powerful, all-natural enzymatic wellness support agent for the cardiovascular system.

Proteases have been called biology's version of Swiss army knives, as they can cut long sequences of proteins into fragments so they can be digested. This process is called proteolysis, and it turns protein molecules into shorter fragments, called peptides, and eventually into their components, called amino acids. We need a steady supply of amino acids for proper growth and repair. 

In addition to breaking down proteins from food, proteases break down proteins involved in swelling and pain and can reduce inflammation. They are also involved in cleaning wounds due to skin injuries.
