Enzyme technology
Kalvatin is based on a cold-adapted trypsin from deep-sea cod. This enzyme has unique properties that make it very effective in counteracting viral and bacterial infections. 

Barrier against infection
Together with a hypertonic solution, the enzyme forms a temporary barrier on skin or mucosa to help strengthening the defense against infections. The barrier reduces the ability of viruses and bacteria to attach to cells and cause disease.  The enzyme's normal activity level is at 4°C. On contact with body temperature the enzyme becomes superactive and the catalytic activity is increased. The catalytic activity is 40-50 times higher than the corresponding enzyme in mammals. 

The enzyme is extracted as a by-product of fish processing and therefore leaves no negative ecological footprint.
