Serrapeptase: Uses, Benefits, Dosage & Safety
Last updated: June 2026 · Reviewed by the FactoWiki Editorial Team for clarity and source accuracy
Quick summary
Serrapeptase is a proteolytic (protein-digesting) enzyme marketed for inflammation, pain, sinus congestion and scar tissue. It's popular in some countries, but rigorous high-quality human evidence is limited.
What is Serrapeptase?
Serrapeptase (serratiopeptidase) is an enzyme originally isolated from bacteria in silkworms. As a 'systemic enzyme' taken on an empty stomach, it's marketed for inflammation, joint and post-surgical pain, sinus and respiratory congestion, and breaking down scar tissue.
What Serrapeptase is commonly used for
In supplements, Serrapeptase is most often included for joint & bone health, respiratory & lung health support. It is used as nutritional support, not as a treatment for any medical condition — the distinction matters, because the claims on a sales page are often stronger than the evidence allows.
How Serrapeptase works
As a protease, serrapeptase breaks down proteins, and it's proposed to reduce inflammatory proteins, thin mucus and dissolve fibrin (the protein in clots and scar tissue). Whether enough intact enzyme is absorbed from the gut to act 'systemically' is debated.
What the evidence says
Here's an honest snapshot of what published research suggests about Serrapeptase — including where the evidence is limited.
- Some older and small studies suggest serrapeptase may reduce post-surgical swelling, pain and mucus, and it's used clinically in parts of Asia and Europe. (PubMed research)
- High-quality, independent evidence is limited, and absorption of the active enzyme is uncertain. (PubMed research)
Typical dosage used in studies
Products are dosed in enzyme activity units; it's typically taken on an empty stomach (often enteric-coated). This is research information for context, not a recommendation — confirm what's appropriate for you with a healthcare professional.
Side effects and safety
Generally reported as well tolerated; possible digestive upset, and rare reports of lung or skin reactions.
Medication interactions and who should avoid Serrapeptase
Medication & safety check
Because it may affect fibrin and clotting, avoid combining with blood thinners and stop before surgery. Caution in pregnancy due to limited data.
This is general information, not personal medical advice. If you take any medication, confirm it's safe to combine with Serrapeptase with your doctor or pharmacist first.

Frequently asked questions
What is serrapeptase used for?
Inflammation, pain, sinus/mucus congestion and scar tissue, as a 'systemic enzyme'.
Does serrapeptase work?
Some small/older studies are positive, but high-quality independent evidence is limited.
How should I take it?
On an empty stomach, usually as an enteric-coated form, to protect the enzyme.
Is serrapeptase safe with blood thinners?
No — avoid combining and stop before surgery, due to possible effects on clotting.
