Serrapeptase is a proteolytic enzyme (an enzyme that breaks down protein) that has been popular in Asia and Europe for almost thirty years. It has been studied for its ability to promote healthy inflammatory responses, improve circulation and support cardiovascular function. SerraGold contains high-potency Serrapeptase combined with a blend of proteolytic enzymes known to support mobility, immune function, and cardiovascular, sinus and systemic health. The vegan serrapeptase in SerraGold eliminates the need for enteric coating.
