I have been using nattokinase for about two years now and, as I have Atrial Fibrillation, it has permitted me to stop taking the anticoagulant I was on.

Successful alternative
4 people found this helpful
I have been taking nattokinase for several years following my Atrial Fibrillation diagnosis. I struggled with standard blood thinners, so this has been my alternative. I've had great success with this brand. It’s beneficial to consult a Naturopathic Doctor or an informed healthcare professional, as many MDs are unfamiliar with it. I also take Serrapeptase alongside it. Great product!

Promotes circulatory health
1 people found this helpful
As a person with Factor V Leiden and long QT syndrome experiencing regular Atrial Fibrillation, I must be cautious with my medications to prevent interactions and clots. Although I am vaccine-free, I did contract the C word two years ago. Natto has been beneficial since then, helping to keep my condition under control. It supports my circulatory system and heart health. The capsule size is ideal and has no aftertaste. I take one capsule each evening and morning alongside my beta blockers. The quality is impressive; I recommend it to anyone facing health issues.

Improved circulation
I have Atrial Fibrillation and take it daily as a precaution against blood clots and for better circulation. It also helps with my cholesterol levels and overall heart health. I prefer it over aspirin, which irritates my stomach. Doctor's Best is a reputable brand.
