Mucus Production

Some nasal congestion is due to excessive mucus production in the sinus cavity, which then narrows the breathable space. Supplements that reduce mucus production may be beneficial for nasal congestion related to allergies or sickness.

Human Effect Matrix

The Human Effect Matrix looks at human studies (it excludes animal and in vitro studies) to tell you what supplements affect mucus production
Grade Level of Evidence
Robust research conducted with repeated double-blind clinical trials
Multiple studies where at least two are double-blind and placebo controlled
Single double-blind study or multiple cohort studies
Uncontrolled or observational studies only
Level of Evidence
? The amount of high quality evidence. The more evidence, the more we can trust the results.
Outcome Magnitude of effect
? The direction and size of the supplement's impact on each outcome. Some supplements can have an increasing effect, others have a decreasing effect, and others have no effect.
Consistency of research results
? Scientific research does not always agree. HIGH or VERY HIGH means that most of the scientific research agrees.
Notes
grade-c
Serrapeptase
Notable Very High See all 4 studies
A somewhat notable decrease in mostly the viscosity of mucus (elasticity is somewhat unreliably decreased), due to the mucolytic properties of serrapeptase. This may be of use for both nasal discharge and lung sputum (cystic fibrosis)
