Key Takeaways
  • Serrapeptase (serratiopeptidase) is a protein-digesting enzyme isolated from bacteria in the digestive tract of silkworms. Beyond digestion, it is expected to have anti-inflammatory, fibrinolytic (fibrin-breaking), and expectorant effects.
  • Some clinical trials suggest improvements in post-tooth extraction swelling, ear, nose, and throat inflammation, and chronic respiratory symptoms. However, systematic reviews indicate that the evidence is still limited (results vary between studies).
  • When taking supplements, it is important to take them on an empty stomach and choose enteric-coated products designed to dissolve in the intestines. Caution is required if you are taking anticoagulants or are pregnant.

Introduction: What is Serrapeptase, the Unusual "Bug-Derived" Enzyme?

Even as diets like low-carb and paleo gain attention, protein remains an essential building block for our bodies. One of the enzymes that breaks it down into amino acids is serrapeptase (also known as serratiopeptidase). The name might make you a bit hesitant, but this is an enzyme discovered in the beneficial bacteria living in the digestive tract of silkworms, and it has been studied since the 1960s. When we actually looked into related literature and supplements, we found that it may work not only as a digestive aid but also for "body repair," such as reducing inflammation and swelling.

What is Serrapeptase? Origins and Main Functions

Origins and Basic Actions

Serrapeptase is a protease (protein-digesting enzyme) that works when silkworms dissolve their cocoons. It is produced by bacteria of the genus Serratia that live symbiotically inside the silkworm. It has the power to break down proteins, and by breaking down unnecessary proteins and fibrin in the body, it is thought to be effective against inflammation, swelling, and sticky mucus.

Its Role as a Digestive Enzyme

Our bodies have many protein-digesting enzymes like trypsin and chymotrypsin, but serrapeptase is a type of food-derived enzyme that we supplement from the outside. Like bromelain from pineapples, it is unique in that it is expected to help break down dietary proteins and act outside the digestive tract.

Expected Health Benefits and Evidence

Reducing Post-Surgical Swelling and Pain

There are studies reporting its effectiveness in reducing swelling after tooth extraction or surgery. In clinical studies from the 1980s, there were cases where it promoted the recovery of range of motion and reduced post-operative edema (swelling). However, due to differences in research methods and the number of subjects, the results are not consistent across all studies.

Effects on Ear, Nose, Throat, and Respiratory Symptoms

Some multicenter trials suggest improvements in symptoms of nose and throat inflammation, chronic sinusitis, and chronic respiratory diseases. On the other hand, a 2013 systematic review in an international journal pointed out that existing studies vary in quality and scale, and further large-scale randomized controlled trials are needed to draw clear conclusions.

Other Actions (Mucus and Fibrinolysis)

Serrapeptase is said to have the ability to break down highly viscous secretions and a fibrinolytic action that breaks down fibrin in the blood, which may contribute to promoting the expulsion of phlegm and improving scar tissue. However, caution is needed for those with bleeding tendencies or when used in combination with anticoagulant medications.

How to Take Supplements, Precautions, and Our Experience

Tips for Intake and Choosing Products

The labeling on commercial supplements varies, using terms like mg or "SPU (serrapeptase units)." Generally, it is said that taking it on an empty stomach (before or between meals) makes it easier to expect systemic effects rather than just digestive purposes. Also, to prevent the enzyme from being deactivated by stomach acid, it is safe to choose products with an enteric coating. In terms of quality, it is good to check for third-party testing or GMP certification.

Side Effects and Contraindications

Reported side effects include gastrointestinal discomfort and, rarely, allergic reactions. In particular, those taking anticoagulants (such as warfarin) or antiplatelet drugs, those scheduled for surgery, and those who are pregnant or breastfeeding should avoid use or consult a doctor. Since the risk of bleeding may increase, increasing the dose based on your own judgment is dangerous.

Our Thoughts

When our geefee team tried a few products, some members felt "relieved" after a tooth extraction or when experiencing severe nasal congestion. Honestly, individual differences are large; some people feel immediate effects, while others find it hard to notice any difference. When trying a new supplement, we recommend observing how you feel over a short period (a few weeks) while checking your physical condition and how it interacts with any medications you are taking.

Conclusion

Serrapeptase is a protein-digesting enzyme derived from silkworms, and in addition to aiding digestion, it is expected to have multifaceted effects such as anti-inflammatory, expectorant, and fibrinolytic actions. While there are promising results in clinical studies, it cannot be called a "cure-all" due to variations in the quality and consistency of the research. When choosing a supplement, select a reliable product, and be sure to consult a specialist if you are using anticoagulants or are pregnant. We also experienced situations where we felt its effects, but it is wise to confirm its safety first and try it little by little.
