Serrapeptase is a proteolytic (protein destroying) enzyme from bacteria native to the digestive system of silkworms. It is the enzyme responsible for dissolving a silkworm’s cocoon.
Traditionally, serrapeptase has been used for its anti-inflammatory properties. Today, it is marketed as a joint health supplement.
Unfortunately, many studies on serrapeptase were poorly structured, with inadequate control groups. The most recent data suggests that serrapeptase is not a very effective supplement, as far as joint health and inflammation is concerned.
Though serrapeptase has been detected in plasma after supplementation, the standard oral dose for serrapeptase is low, which means very little is absorbed through the intestines. This may be one of the reasons serrapeptase is unreliable and not very effective.
Serrapeptase has been found to have the ability to liquefy mucus and reduce bacterial biofilms (reducing bacteria’s ability to stick to surfaces and each other). This means serrapeptase may be able to reduce phlegm buildup, nasal discharge, lung symptoms of cystic fibrosis and help other compounds fight bacteria. Additional research is needed to confirm these effects.
