What is Serrapeptase?
Serrapeptase is a proteolytic enzyme originally isolated from bacteria found in the digestive tract of silkworms. This enzyme, scientifically known as serratiopeptidase, was first discovered in the 1960s and has been used medicinally in Japan and Europe for decades. Serrapeptase belongs to a class of enzymes called proteases, which break down proteins into smaller peptides and amino acids.
The enzyme is produced by the bacterium Serratia marcescens, which naturally occurs in the silkworm’s gut and helps the insect dissolve its cocoon when emerging as a moth. Today, commercial serrapeptase supplements are produced through bacterial fermentation in controlled laboratory conditions, making them suitable for vegetarians and vegans.
Serrapeptase is classified as a nutraceutical compound and is available as a dietary supplement in many countries, including the United States. It’s often marketed for its potential anti-inflammatory and protein-dissolving properties, though regulatory approval varies by region.
Health benefits & uses
Limited evidence supports serrapeptase for reducing inflammation and pain. Some small studies suggest it may help with post-surgical swelling and inflammatory conditions, but larger, well-designed clinical trials are needed to establish definitive benefits.
Limited evidence exists for respiratory health applications. Preliminary research indicates serrapeptase might help break down mucus and reduce respiratory inflammation, potentially benefiting conditions like chronic obstructive pulmonary disease (COPD) and sinusitis. However, these studies are small and require replication.
Limited evidence suggests potential cardiovascular benefits. Some research has explored serrapeptase’s ability to break down fibrin and other proteins involved in blood clot formation, but human studies are insufficient to support specific cardiovascular claims.
Insufficient evidence exists for other claimed benefits, including wound healing enhancement, scar tissue reduction, and treatment of various inflammatory conditions. While these applications are commonly cited, robust clinical evidence is lacking.
How it works
Serrapeptase functions as a proteolytic enzyme, meaning it breaks down proteins by cleaving peptide bonds. When taken orally, the enzyme is designed to survive stomach acid through enteric coating and be absorbed in the small intestine.
Once in the bloodstream, serrapeptase may target specific proteins involved in inflammation and tissue repair. The enzyme appears to preferentially break down “dead” or damaged proteins while leaving healthy tissue intact. This selective action is thought to contribute to its anti-inflammatory effects.
The enzyme may work by reducing the production of inflammatory mediators, breaking down fibrin (involved in blood clotting), and potentially dissolving mucus by targeting the proteins that give it structure. Serrapeptase may also influence immune cell activity and reduce the accumulation of inflammatory fluids in tissues.
Dosage
Typical adult dosages for serrapeptase range from 10,000 to 60,000 SPU (Serratiopeptidase Units) per day, often divided into 2-3 doses. Some studies have used doses up to 30mg daily. There is no established RDA or UL for serrapeptase as it’s not an essential nutrient.
Most supplements recommend taking serrapeptase on an empty stomach, at least one hour before or two hours after meals, to optimize absorption and prevent the enzyme from being used to digest food proteins instead of exerting systemic effects.
Dosing should always be guided by a healthcare provider, especially for therapeutic applications. Starting with lower doses and gradually increasing may help minimize potential side effects. Treatment duration varies depending on the intended use, with some protocols lasting several weeks to months.
Food sources
Serrapeptase is not naturally found in food sources available for human consumption. The enzyme is exclusively produced by the bacterium Serratia marcescens and is only available through dietary supplements.
Unlike other proteolytic enzymes such as bromelain (found in pineapple) or papain (found in papaya), serrapeptase must be obtained through supplementation. All commercial serrapeptase products are manufactured through controlled bacterial fermentation processes.
Safety & side effects
Serrapeptase is generally considered safe for most healthy adults when used short-term. Common side effects may include gastrointestinal upset, nausea, and skin reactions in sensitive individuals.
More serious but rare side effects can include bleeding complications, particularly in individuals with bleeding disorders or those taking anticoagulant medications. Some users have reported allergic reactions, including skin rashes and respiratory symptoms.
Long-term safety data is limited, and the effects of prolonged serrapeptase use haven’t been thoroughly studied. As with any supplement, it’s important to use serrapeptase under healthcare supervision, especially for extended periods.
Interactions
Serrapeptase may interact with anticoagulant and antiplatelet medications, including warfarin, heparin, aspirin, and clopidogrel, potentially increasing bleeding risk. Close monitoring is essential if combining these substances.
The enzyme may also interact with other supplements that affect blood clotting, such as fish oil, garlic extract, ginkgo biloba, and other proteolytic enzymes. This combination could amplify anticoagulant effects.
Serrapeptase might affect the absorption or effectiveness of certain medications when taken simultaneously. Taking the enzyme away from other medications (separated by at least 2 hours) may help minimize potential interactions.
Who should be cautious
Individuals with bleeding disorders, upcoming surgeries, or those taking anticoagulant medications should avoid serrapeptase or use it only under strict medical supervision. Pregnant and breastfeeding women should avoid serrapeptase due to insufficient safety data.
People with allergies to bacterial products or those with compromised immune systems should exercise caution. Individuals with inflammatory bowel disease or active gastrointestinal ulcers should consult healthcare providers before use.
Those scheduled for surgery should discontinue serrapeptase at least two weeks prior to the procedure due to potential bleeding complications.
Frequently asked questions
Can serrapeptase dissolve blood clots?
While serrapeptase can break down fibrin, a protein involved in blood clots, there’s insufficient evidence to support its use for treating existing blood clots. This is a serious medical condition requiring professional treatment.
How long does it take to see effects from serrapeptase?
Response times vary considerably among individuals and depend on the condition being addressed. Some people report noticing effects within days to weeks, while others may require longer periods. Consistent use under healthcare guidance is typically recommended.
Is serrapeptase better than other proteolytic enzymes?
Different proteolytic enzymes have varying properties and potential applications. Serrapeptase’s unique characteristics include its bacterial origin and specific protein targets, but comparative research between different proteolytic enzymes is limited.
Can I take serrapeptase with food?
Serrapeptase is typically recommended on an empty stomach to prevent the enzyme from being used for food digestion rather than systemic effects. Taking it with food may reduce its effectiveness for therapeutic purposes.
Are there any quality considerations when choosing serrapeptase?
Look for supplements with enteric coating to protect the enzyme from stomach acid, third-party testing for purity, and clear potency labeling in SPU units. Choose reputable manufacturers that follow good manufacturing practices.
