Doctor’s Best Serrapeptase promotes and maintains healthy sinus and airway function and healthy immune response*
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 Serratia bacteria species strain E15
Uses Serrateric™, a coating that protects the enzyme from stomach acids until it reaches the intestines and therefore optimizes absorption
Gluten Free, Non-GMO, Vegetarian, Vegan
90 Veggie Caps, 270 Veggie Caps
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.*
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.*
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.*
Are any silk worms harmed in the production of Doctor's Best Serrapeptase?
No. Serrapeptase is a proteolytic enzyme isolated from the non-pathogenic bacteria Serratia species found in the digestive tract of the Japanese silkworm. The bacteria from which the enzyme is isolated was first found in the digestive tract of the Japanese silkworm however, the enzyme is produced through a fermentation process. No silkworms are harmed in the process.
Does the Doctor's Best Serrapeptase product contain corn?
This product does contain non-GMO Maltodextrin from corn whis is found in the Serrateric™ ingredient.
What is Serrateric?
Serrateric™ is a non-GMO natural coating-free acid protection system. Serrateric™ is a combination of approved food additives (self-affirmed GRAS) that work to provide gastric protection for pH sensitive enzymes without the need for additional coating.
What is the country of origin for Doctor's Best products?
Doctor’s Best products are quality tested and manufactured in the United States using highly qualified cGMP manufacturers and raw material ingredients. Doctor’s Best sources raw materials from around the world and ingredients are subject to the intense testing and verification regardless of geography of origin.
