too soon to tell

Posted by Reviewer1310601 on Feb 17, 2012

Been on this for a month. I am taking it because my enzyme book recommended it for poly mylgia . It has no negative side effects. Dr. Best is the best quality with the best price I have found.

Trying it out based on others' reviews

Posted by Reviewer2635763 on Nov 08, 2015

I tried it out based on other people's reviews. Don't see much effect but then again I don't know what effect to be looking out for. If it improves blood circulation, it's good enough for me. :) Update: I've noticed an obvious change in my ability to sweat after taking this. During exercise i sweat faster and much more than if I didn't take this supplement.

Using these for my cats

Posted by 4697690588235874463 on Mar 06, 2014

My 16 year old Burmese cats have numerous health conditions so I have added Nattokinase to their mixture of the many other herbs I give them to help circulate their blood. Seems they are going really well. I would definitely use this product.

Thank you very much for delivering my order as promtly as you did. I'm pleased with the product and the price, but more importantly I wanted to be sure and thank you for the way you manage your site. I had a question about my purchase. The answer to my question was thorough and curtious. That is very much appreciated. I will buy from you again.

Don't know if this is working or not

Posted by Reviewer2850810 on Sep 28, 2011

I'm not 100% sure if this is working as I still have some circulation issues in my legs, but there may be other reasons for that.
