When most people hear the word “enzymes,” they think of digestive aids taken with a meal. This common understanding overlooks systemic enzymes, a distinct category of protein molecules designed to be absorbed into the bloodstream. Circulating throughout the body, their function is not to digest food but to catalyze biological reactions that support overall tissue and cellular health.
Defining Systemic Enzymes
Systemic enzymes are protein-based biological catalysts absorbed intact through the small intestine lining into the bloodstream. The term “systemic” refers to their function throughout the body’s systems, acting beyond the gastrointestinal tract. Unlike digestive enzymes, which break down food, systemic enzymes are taken on an empty stomach. This timing ensures they bypass the digestive process and enter the circulation to perform their non-digestive roles.
These enzymes are often classified as proteolytic enzymes, meaning they specialize in breaking down proteins into smaller components. Common examples include plant-derived enzymes like bromelain (from pineapple) and papain (from papaya). Other proteases, such as serrapeptase (derived from a bacterium) and nattokinase (from fermented soybeans), are highly valued for their systemic activity. Their ability to cleave protein bonds allows them to target and dismantle specific types of proteins circulating in the blood and tissues.
Biological Roles in the Body
Once in the bloodstream, systemic enzymes serve as an internal “cleanup crew,” modulating various biological processes. A primary action is the modulation of inflammation, achieved by breaking down excess inflammatory proteins and immune complexes. Systemic enzymes help dismantle the proteins the immune system uses to tag damaged tissue, effectively turning down the inflammatory response. This targeted action helps resolve inflammation without broadly suppressing the immune system like conventional medications.
Another significant role is fibrinolysis, the process of breaking down fibrin, a protein involved in blood clotting and scar tissue formation. While fibrin is necessary for wound healing, excess amounts can lead to tissue stiffness, adhesions, and poor circulation. By helping to dissolve excess fibrin, these enzymes improve blood flow, allowing essential nutrients and oxygen to reach damaged areas more efficiently. This action also reduces the viscosity of the blood, supporting healthier circulation throughout the microvasculature.
These protein-cleaving enzymes assist in general protein catabolism by targeting foreign or damaged proteins. They help clear cellular debris, including waste products and circulating immune complexes that can accumulate. By facilitating the breakdown and removal of these unwanted materials, systemic enzymes support the body’s natural detoxification pathways. This cellular housekeeping function supports immune function by helping white blood cells operate more effectively.
Common Therapeutic Applications
The biological actions of systemic enzymes translate into several common therapeutic uses. Because of their ability to break down inflammatory molecules and reduce swelling, they are frequently used to support joint and muscle comfort. Individuals with temporary muscle soreness or those seeking to maintain joint mobility often use these enzymes to aid recovery.
The fibrinolytic property also makes them useful in post-surgical healing and recovery from injury. By helping to break down excess fibrin that forms scar tissue, systemic enzymes are utilized to minimize the formation of adhesions and internal scarring. Their action in reducing swelling and clearing tissue debris can accelerate the body’s natural healing timeline following trauma.
Systemic enzymes are commonly employed to support cardiovascular health due to their positive impact on blood flow. The reduction of blood viscosity and the breakdown of excess fibrin contribute to the maintenance of healthy blood and arterial function. These applications leverage the enzymes’ core mechanisms to help the body address the byproducts of chronic inflammation and tissue damage.
Sources and Considerations for Use
Systemic enzymes originate from three main sources: plants, animals, and microorganisms. Plant-based sources include bromelain and papain, while animal-based enzymes like trypsin and chymotrypsin are derived from the pancreas. Microbial sources, such as serrapeptase and nattokinase, are cultivated through the fermentation of bacteria or fungi.
To ensure these protein molecules survive the acidic environment of the stomach, they are typically formulated with an enteric coating. This specialized coating prevents the enzymes from being degraded by stomach acid, allowing them to pass intact into the small intestine for systemic absorption. Taking them on an empty stomach, usually one hour before or two hours after a meal, is essential for their systemic effect.
Because of their impact on blood viscosity and fibrin breakdown, systemic enzymes can enhance the effects of blood-thinning medications. Therefore, individuals taking anticoagulants must consult with a healthcare professional before starting a systemic enzyme regimen. These supplements are generally well-tolerated, but proper timing and awareness of potential interactions are necessary for safe and effective use.
