So how does Serrapeptase Pro work? It contains the Serrapeptase enzyme, also known as Serratiopeptidase. Enzymes play a role in every function of the human body - our eyes blink and our hearts beat because of enzymes. By supplementing with a high-quality systemic enzyme formula, you help to support the natural function of your body. When you're naturally at your best, you feel at your best! Serrapeptase has been used throughout the world for over 30 years to promote a variety of therapeutic benefits, including support for your cardiovascular, circulatory, and immune health. Many brands use serrapeptase sourced from silkworms, but Enzyme Science only uses a vegan source. Within your body, you sometimes have proteins that are dead, damaged, or don't belong. Serrapeptase helps to break down those proteins, as well as excess mucus. In Serrapeptase Pro, the benefits go beyond just this one enzyme. A powerful blend of Protease enzymes reinforces the power of this product for extra strength support. Plus, Enzyme Science does enzymes better. As the practitioner division of Enzymedica, the nation's largest retail brand of enzymes, Enzyme Science pioneered enzyme technologies, including Thera-blend. Thera-blend combines enzymes that work in wide ranges of pH and temperature to better support the needs of all individuals.
