What is Doctor’s Best Serrapeptase? Doctor’s Best Serrapeptase promotes and maintains healthy sinus and airway function as well as a healthy immune response. It helps dissolve hard particles made of protein that cause unwanted side effects from toxins, scar tissue, blood clots and cysts. Serrapeptase is a proteolytic enzyme that comes from the Serraitia bacteria species strain E15 and has been studied for over 40 years. As serrapeptase can be destroyed by stomach acids, Doctor’s Best Serrapeptase uses Serrateric, a coating that protects the enzyme until it reaches the intestines and therefore optimizes absorption. How does it work? The mucous membranes are a thin tissue layer or epithelium that lines the body’s hollow structures opening to the exterior such as the upper respiratory system. They secrete a slightly viscous fluid called mucus, which is actually a complex viscoelastic gel that lubricates and moistens the cavity surfaces. As a part of normal, healthy physiology, mucus is the first line of defense in the nose and lungs to trap and filter inhaled dust, pollutants, and other potentially damaging agents. Proteolytic enzymes such as serrapeptase can break down inappropriate protein complexes in the mucus. This helps support the healthy balance between adequate mucus viscosity/elasticity and airway comfort associated with the mucus membranes of the respiratory system. As a a proteolytic enzyme, serrapeptase helps dissolve unwanted hard particles made of protein including scar tissue and blood clots. Why should I take Doctor’s Best Serrapeptase? As part of a healthy physiology, mucus is the first line of defense in the nose and lungs to trap and filter inhaled dust, pollutants and other potentially damaging agents. When your body produces too much mucus, it can make your sinus area feel ‘stuffed up’ or discomfort in your sinus or airway. Proteolytic enzymes can break down inappropriate protein complexes in the mucus. This results in a favorable viscosity of nasal and bronchial mucus which can support airway clearance and enhance nasal airway comfort.
