Doctor's Best, Best Nattokinase 30 Veggie Caps

Posted by Reviewer1346541 on Mar 11, 2008

I really thank the Lord for allowing to find such a product!!!!!!!!! I had a blood clot in my right leg and didn't want to go in the hospital. I kept the faith and ordered the nattokinase because my leg was so big and swollen. To make a long story short. Nattokinase dissolved my blood clot and my swelling went down in a matter of days!!!!!!! So I will continue to order this product to keep me from having blood clots. This product saved me thousands of dollars by keeping me out of the hospital. This product is great for anybody that has had heart attacks or strokes or to prevent from having them. And I know what I'm talking about because I've been on Coumadin and everything.

I noticed better circulation to my face and feet almost immediately. My rosacea seems to be clearing up slowly and steadily.

This is THE very type of Nattokinase that is used in research trials. It really does what the research shows. I've had excellent results! And the price is unbelievable! It's the obvious choice!

Ran out of this and within a few days my feet and legs were back to hurting and swelling up. I cannot believe the difference this has made in the quality of my life and I will never be without!
