Nattokinase is an enzyme extracted from natto cheese, a dietary staple in Japan and believed to be the reason behind the countrys record low rate of heart disease. Nattokinase and Cardiovascular Health Experts credit much of Japans reputation for the lowest heart disease rate to nattokinase, an enzyme in the fermented soy-based cheese called natto. Although a Japanese staple for over 2000 years, the sticky, odorous cheese is, needless to say, an acquired taste. Fortunately the advantage is in the enzyme, now available in Rutozym. Hiroyuki Sumi, MD, a researcher of the Japan Ministry of Education, discovered the enzyme and its remarkable benefits while searching for a natural way to break down excess fibrin in the blood, a major cause of heart disease, stroke, senility and even sudden death. Pleased with how successfully it dissolved fibrin and improved blood flow, Sumi (affectionately known as “Dr. Natto”) gave nattokinase its name. For those seeking for a pure, potent source of nattokinase without having to travel to Asia, look no further! Nattokinase 1500 from Wobenzym USA provides a whopping 1500 fibrin units (FU) of nattokinase per serving. Unlike other similar products, Nattokinase 1500 is an enterically coated tablet. Each tablet passes through the stomach without being digested, where they are then absorbed into the blood stream via the small intestine. It is here in the blood stream where nattokinase gets to work. Other products, which get digested in the stomach, become less effective once they finally reach the bloodstream. Serving Size: 2 Tablets Nattokinase providing 1,500 FU per serving (20,000FU/gm) 75mg * Rutin bioflavonoid Complex (Vitamin P) 100mg * * Daily value not established. Other Ingredients: Plant Fiber, Modified Cellulose Gum, Colloidal Silica, Vegetable Magnesium Stearate, Vegetable Stearic Acid, Titanium Dioxide and pH-Resistant Enteric Coating.
