Protease: benefits, dosage, contraindications

Mis à jour le

Proteolytic enzymes are a family of enzymes that hydrolyze peptide bonds in proteins or peptides. Proteolytic enzymes are present in all tissues, in cell membranes, the cytoplasm, and individual organelles. These enzymes can be endopeptidases, which hydrolyze peptide bonds within the protein, or exopeptidases, which cleave terminal amino acids. Proteolytic enzymes differ in the size of the substrate they degrade, the number and types of amino acids they cleave, their optimal pH for activity, and their localization in the organism. In the body, proteolytic enzymes play many roles, including the degradation of intracellular proteins, the control of physiologically active peptides, the presentation and recognition of antigens in the context of the cellular immune response, muscle remodeling and function, collagen turnover, digestion, blood coagulation... Pathological changes in proteolytic enzyme activity lead to inflammation, tissue damage and muscle wasting. In addition, changes in proteolytic enzyme activity are at least partly responsible for changes in muscle development that occur both as benefits and as side effects of certain drugs. The activity of a large number of proteases is controlled by cellular inhibitors. Inappropriate or pathological activity plays a role in various disorders, including joint inflammation, muscle degradation, including cachexia and sarcopenia, pulmonary disorders, and dementia. Proteolytic enzymes, as enzymes that break down proteins present in the body or on the skin, are consumed to promote digestion or the degradation of proteins involved in pain and inflammation.

Several randomized, double-blind, controlled clinical trials (> 2), including a significant number of patients (>100), with positive conclusions for the indication.
One or more randomized studies, or several cohorts or epidemiological studies, with positive conclusions for the indication.
Clinical studies exist but are uncontrolled, with conclusions that may be positive or conflicting.
No clinical studies to date that can demonstrate the indication.


Skin healing
✪✪✪✪✪

Proteolytic enzymes are involved in wound healing. For example, collagenase breaks down clots and then participates in collagen remodeling. Elastase breaks down elastin to allow for increased collagen deposition. Some proteolytic enzymes degrade necrotic tissues after cell rupture.

Rheumatoid arthritis
✪✪✪✪✪

Proteolytic enzymes are of interest for rheumatoid arthritis. In human research, oral intake of proteolytic enzymes reduces levels of circulating immune complexes and increases levels of the complement component iC3b. In humans and in animal models of edema, orally administered proteolytic enzymes have been shown to have anti-inflammatory effects. The mechanism of action may be related to inhibition of endogenous proteinases following increased activity of proteinase inhibitors. Proteolytic enzymes reduce levels of inflammatory cytokines and the resulting T-cell response.
