Enzymedica SerraGold - High-potency serrapeptase enzymes work to optimize the body’s recovery processes and immune function. Serrapeptase is a proteolytic enzyme, which means that it breaks down protein. While enzymes are best known for breaking down food in the gut, they can also break down compounds elsewhere throughout the body. Serrapeptase is one of those enzymes that works well outside the gut. It has the ability to survive the digestive tract and circulate through the body, breaking down unwanted and damaged proteins anywhere it finds them, and helping the immune system and physical recovery.
