Where does serrapeptase (the active ingredient in SP-Zyme) come from?
Serrapeptase is a naturally occurring enzyme grown in a laboratory. It was originally discovered in the digestive system of the silk worm. The silk worm secretes this enzyme to dissolve a hole in the cocoon, allowing it to escape. Strand for strand, silk is stronger than steel, so this is a demonstration of the power of serrapeptase.
