Supports Cardiovascular Health

  • Enhances circulation
  • Promotes production of plasmin

Fibrin is a protein found in the blood. Maintaining healthy levels of fibrin promotes healthy coagulation of blood for an optimally functioning cardiovascular system.

Natto-K contains specialized blends of enzymes including Nattokinase with NSK-SD—the only form of nattokinase that does not contain vitamin K2—to enhance the body's production of plasmin. Plasmin breaks down excess fibrin, which may improve circulation. Natto-K may help maintain already healthy levels of blood clotting factors within a healthy range.

Thera-blend is an exclusive process that combines multiple strains of enzymes that work in specific pH levels, resulting in superior performance in the body.

Great product

Posted by Reviewer1106421 on Aug 24, 2011

Again, another good product that has no fillers, binders, etc. Best companies do not add the above ingredients to their products.

Sent one bottle to my 92-year-old mother (who lives several states away from me) because she has painful deep vein thrombosis in her legs. In less than a bottle, the pain on the bottom of her feet is gone...still has some pain in legs. I just ordered 2 more bottles for her. (I take it, too.)

Natto-K for MS

Posted by Reviewer1062064 on Mar 01, 2011

I take this instead of Italian Dr. Zamboni's procedure for increasing blood flow out of the brain. Jury is still out if it is working, no evidence either way, hence the two stars out of five.
