Good to trade with iherb. Shipping duration need nearly a month to reach my country. But, I am still satisfied.

Thanks for your feedback!

I have been taking Nattokinase for more than 10 years since I have a stroke - it works by supporting normal circulation, blood flow, and blood viscosity.

Thanks for your feedback!

Good dosage and good price

Posted by DAB598 on Mar 13, 2017 | Verified Purchase

Normal daily dose is 4,000 FU; dividing the dose generally makes it more effective, so I like this size better. Pricing on iHerb is very competitive with other alternatives.

Thanks for your feedback!

Natto is good for you.

Nattokinase is from a soupy food that the Japanese eat regularly. It is a fermented soy super-food. It naturally melts blood clots and keeps the blood running smoothly. It is best taken on an empty stomach. ... My wife and I take two 2,000 mg capsules of it from Doctor's Best in the middle of the night. It certainly works for us.
