Serrapeptase Source (Serratia marcescens enzyme): Benefits, Dosage, Safety & Evidence

Frequently asked questions

How does serrapeptase work to reduce inflammation in the body?

Serrapeptase works through proteolytic action, meaning it breaks down proteins into smaller components. It specifically targets and hydrolyzes inflammatory mediators like bradykinin, which are responsible for pain and swelling. By thinning mucus secretions and reducing fluid accumulation in injured tissues, it helps alleviate symptoms of sinusitis and post-surgical swelling. Unlike NSAIDs, it modulates inflammation without inhibiting prostaglandins. Evidence Level: C.

Can I take serrapeptase with blood thinners or anticoagulants?

Serrapeptase should not be taken with blood thinners or anticoagulants due to potential drug interactions. As a proteolytic enzyme, it possesses fibrinolytic properties that can thin the blood and inhibit platelet aggregation. Combining it with medications like warfarin, aspirin, or heparin significantly increases the risk of excessive bleeding and bruising. Always consult a physician before use if taking anticoagulants. Evidence Level: C.

What is the recommended dosage for serrapeptase?

The typical adult dosage for serrapeptase ranges between 60,000 and 120,000 SPU (Serratiopeptidase Units) per day. For best results, it must be taken on an empty stomach, at least 30 minutes before eating or two hours after a meal. Taking it with food causes the enzyme to break down dietary proteins instead of absorbing into the bloodstream to target inflammation. Evidence Level: C.

Is serrapeptase safe to take during pregnancy or breastfeeding?

Serrapeptase is considered unsafe during pregnancy and breastfeeding. There is currently insufficient clinical data to confirm its safety for fetal development or nursing infants. Due to its proteolytic nature and potential effects on blood clotting mechanisms, it poses theoretical risks to both mother and child. Consequently, pregnant or breastfeeding women are advised to avoid this supplement. Evidence Level: D.

Does serrapeptase help with sinusitis and nasal congestion?

Serrapeptase is frequently used to treat sinusitis due to its mucolytic properties. It works by breaking down the protein structure of mucus, making it less viscous and easier to clear from the nasal passages. Some studies suggest it can help reduce facial pain, nasal obstruction, and post-surgical swelling in the ear, nose, and throat area, though evidence remains preliminary. Evidence Level: C.

Summary

Serratiopeptidase is a proteolytic bacterial metalloprotease produced by Serratia marcescens, utilized for its anti-inflammatory, analgesic, and anti-edemic properties [PMID:33134103, PMID:38502196].

Background

Serratiopeptidase is a zinc-containing metalloprotease with a molecular weight of approximately 50-53 kDa [PMID:31125647, PMID:32497664, PMID:38582407]. It is produced from the bacterium Serratia marcescens, which can be isolated from sources such as soil, sugarcane stems, and the stomach wall or gut of silkworms (Bombyx mori) [PMID:38821483, PMID:38800751, PMID:39452598].

Active compounds

The active component is the serratiopeptidase enzyme, a serine protease of the trypsin family [PMID:32104332].

Mechanism of action

Serratiopeptidase exhibits a high affinity for cyclooxygenase (COX-I and COX-II), which are key enzymes in the production of inflammatory mediators such as prostaglandins, interleukins, and thromboxanes [PMID:32104332]. It also functions by breaking down fibrin and thinning fluids formed during inflammation [PMID:38502196, PMID:32953681].

Clinical evidence

Evidence BSurgical removal of impacted mandibular third molar (Trismus)

Serratiopeptidase significantly improved trismus compared to control on the 4th postoperative day [PMID:33653320]. It improved trismus better than corticosteroids [PMID:29618875].

Evidence BSurgical removal of impacted mandibular third molar (Swelling)

Serratiopeptidase was effective in reducing swelling from the 2nd to 5th postoperative day [PMID:32855925]. However, a meta-analysis of RCTs found no significant difference in swelling reduction compared to other treatments [PMID:29618875].

Evidence CGeneral Inflammatory Conditions

Used in the treatment of arthritis, sinusitis, bronchitis, and postoperative swelling [PMID:36291677, PMID:40753267].

Safety & adverse effects

Serratiopeptidase is described as a safer anti-inflammatory alternative to NSAIDs [PMID:36291677]. However, some reviews note that data on safety and tolerability require further detailing [PMID:33134103].

Drug interactions

Serratiopeptidase is commonly used in combination with antibiotics to treat postoperative swelling and may reduce the development of antibiotic resistance due to its anti-biofilm activity [PMID:36291677, PMID:38502196].

Evidence summary

Evidence is mixed; while some clinical trials and reviews suggest efficacy in reducing trismus and inflammation, systematic reviews indicate a lack of conclusive evidence and a need for more scientific data to back reported impacts [PMID:23380245, PMID:29618875, PMID:33134103].
