Synopsis

Source of validity: Scientific
Rating (out of 5): 2

Serrapeptase is a proteolytic enzyme originally isolated from bacteria in the intestines of silkworms. It has been investigated for its ability to reduce inflammation, break down non-living tissue, and modulate mucus viscosity. Several small clinical studies and in vitro experiments have examined serrapeptase's potential to reduce viscosity and thickness of mucus secretions, particularly in conditions like chronic sinusitis and bronchitis. For example, a study published in the journal Ear, Nose & Throat Journal (2004) showed that serrapeptase could improve symptoms and reduce nasal secretion viscosity in patients with chronic sinusitis. Another earlier study (Nakamura et al., 2003) indicated potential benefit in reducing sputum viscosity among patients with chronic respiratory diseases.

Despite these findings, the quality of evidence is limited by small sample sizes, lack of large-scale randomized controlled trials, and variability in study design. There is a plausible mechanism whereby serrapeptase could support mucus membrane health by breaking down excess or thickened mucus, but robust, high-quality clinical evidence is lacking. Therefore, while there is scientific rationale and some preliminary support, it is not yet a well-established or universally accepted intervention for mucus membrane support. The evidence rating is moderate to low (2 out of 5), reflecting promising but inconclusive data.
