Advanced Info

Serrapeptase by Natural Factors is a naturally occurring enzyme that effectively reduces pain, swelling, and ear and nose mucous build-up stemming from injury, surgery, and infections. It is a proteolytic enzyme, meaning that it helps break down proteins into simpler compounds, working to remove dead or damaged tissue, thin respiratory fluids, and disrupt pain pathways. It eases symptoms from ear, nose, and throat infections, such as secretions and congestion, and has been called the “miracle enzyme” for its broad range of health-promoting benefits.

Serrapeptase is prepared under highly controlled conditions through a fermentation process using cultures of the non-pathogenic bacterium Serratia marcescens E-15. Two potencies are available for customizable relief: a 60,000 SU (active serratiopeptidase units) formula and a double-strength 120,000 SU formula delivered in delayed-release capsules. This allows the delicate enzymes to pass through the acidic stomach environment intact so that they can be released and absorbed in the small intestines.

The convenient 1–2 dose per day formulas are vegan friendly and free of GMOs. They are ideal for anyone recovering from post-traumatic swelling due to injury or surgery and people who want comfort and relief for better health without significant side effects.
