Serrapeptase, a proteolytic enzyme derived from the intestines of silkworms is not found in any foods or fruits. It is widely available as a supplement and purported to have various health benefits; however, medical doctor and author Ray Sahelian urges caution in the use of serrapeptase until more is known about its long-term benefits and side effects. Seek the advice of your physician before you take any food supplements.


Serrapeptase, also known as serrapeptidase, serratiopeptidase or serratia peptidase is derived from the microorganism serratia, which naturally occurs in the intestines of silkworms. Serrapeptase is also found in other microorganisms associated with the bacteria serratia sp. E-15, such as E. coli and salmonella, according to a serrapeptase review site, Serrapeptase.org.


Serrapeptase dissolves dead tissue without harming living cells, according to Serraptase.org. This is reflected in its ability to dissolve the fibrous cocoon of silkworms in the intestines, enabling the moth to emerge. Serrapeptase has been used to reduce pain and inflammation in a number of conditions, such as nose and throat infections, ear infections, carpal tunnel syndrome and fibrocystic breast disease, according to Serrapeptase.org. However, in a study by the Lady Hardinge Medical College in New Delhi, India, serrapeptase illustrated little analgesic and anti-inflammatory action compared to ibuprofen and paracatemol.

The ability of serrapeptase to remove dead tissue might enable it to combat cardiovascular and arterial disease, which can lead to heart attacks and strokes. According to Hans Alfred Nieper, former president of the German Society of Oncology, serrapeptase may dissolve fibrous blockages and blood clots. No clinical evidence backs these assertions. Seek the advice of your doctor before you use serrapeptase for any medical condition.


Serrapeptase might cause discomfort and various symptoms in some people, Sahelian notes. These may include minor aches and pains, nausea, stomach upset, coughs and the risk of pneumonia in elderly users.
