Doc advised Eliquis for a potential blood clot in left leg after having a back surgery. After 2 months there didn't seem to be any change or benifit. So after some research, I found your Nttokinase. Not only have I seen a change, spider veins that I've had for years on the top of my feet started to dissapear. Very happy with the results and quality of your product. Thank you! PS. A whole lot cheaper too.

I have been taking it and first thing I observed was my bp had a good drop- I am not sure yet. I think need to give it time. I will say that I was terrified of the treadmill test but passed it!! yay. Dr says no observable signs of heart issue. My regular MD was insisting on statins bc of a 2 pt over average in cholesterol reading in the bad cholesterol. I cut down sugar and started Berberine. Working well so far.

I don't feel like it has been enough time for me to tell if it is helping. But I do notice that when I take it my inflammation is down and I don' t have that sluggish feeling.

I just started using this supplement but from what I can tell it seems to be working fine

I hope it is working. Took Natto in hopes to heal from covid issues and prevent or shrink clotting. Lot of research has been done on Natto so Im in hope that it is working. Im still alive. Pills are better than the taste of actually eating Fermented soybeans.

Don't need them right now but have them just in case if I or family member needs.

I ordered your stronger version of NattoKinase from Amazon but instead, your regular Nattokinase was delivered but Amazon said that your company does not allow returns. So I wasted my money. I will never order any product from your company again

I like your product, but was disappointed that the coupon you sent me for a free bottle, was not accepted at checkout and you never responded to my complaint about it.
