Serratiopeptidase, also known as Serrapeptase, is a proteolytic enzyme (an enzyme that breaks down protein) that has been popular in Asia and Europe for almost thirty years, but is now being recognized worldwide. It was originally discovered in the digestive tract of the Japanese silk worm but is now derived from the bacteria of the genus Serratia. Serrapeptase has the ability to survive the digestive tract and remain active while circulating throughout the body. 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, cardiovascular, sinus and systemic health. The vegan serrapeptase in SerraGold eliminates the need for enteric coating. SerraGold is easy on the stomach. SerraGold contains Thera-blend enzymes. Thera-blend is an exclusive process that combines multiple strains of enzymes that work in specific pH levels, resulting in superior performance in the body.
