Nattokinase 1500 is an enzyme extracted from natto cheese, a dietary staple in Japan and believed to be the reason behind the country s record low rate of heart disease. 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 the nattokinase goes to work. Other products, which get digested in the stomach, become less effective once they finally reach the bloodstream. *The products and the claims made about specific products on or through this site have not been evaluated by the United States Food and Drug Administration and are not intended to diagnose, treat, cure or prevent disease.
