What is nattokinase and what does it support?

Nattokinase is an enzyme derived from natto, a fermented soybean food, studied for its role in supporting healthy circulation and cardiovascular wellness.

What does 4,000 FU mean and why does it matter?

FU stands for fibrin units, the standard measure of nattokinase enzymatic activity. Each 2-capsule serving provides 4,000 FU, the dose range used in published human research on nattokinase and cardiovascular markers.

When and how should I take nattokinase?

Take on an empty stomach as directed on the label, either 30 minutes before a meal or 2 hours after eating.

Is nattokinase safe to take with other medications?

Nattokinase has fibrinolytic properties. Consult your provider before use if taking anticoagulants or antiplatelet medications, have a bleeding disorder, or are scheduled for surgery. Do not exceed the labeled dose.

Is Double Wood Nattokinase third-party tested?

Every batch tested for purity, potency, heavy metals, and microbial safety. Third-party tests by ISO/IEC 17025 accredited labs. COAs published openly.

Clean way to combat arteriosclerosis

I’ve been taking 20,000 units of nattokinase daily for quite some time now. From what I’ve read, there’s research suggesting it may support cardiovascular health, which is what initially got me interested. Personally, I haven’t noticed any side effects at this dose. I think consistency is key with something like this, taking it regularly seems to matter more than anything else. This brand has been reliable for me over the years. The quality feels consistent and the price is reasonable compared to others I’ve looked at. I’ve stuck with it for a while now and plan to continue.
