Following a recommended protocol, the chronic wet cough that has been bothering me for months is gone. I've been using this 2x per day on an empty stomach.

Blood pressure

This product seems to help lower blood pressure as my blood pressure was noticeably lower after having taken Nattokinase for just a few days. I take 400mg a day and the tablets are easy to take. After my down research I found that NSK-SD Nattokinase was the best form to take this supplement.

Nattokinase for maintaining general heart health

Nattokinase is a potent enzyme derived from fermented soybeans (natto) that promotes cardiovascular health by acting as a natural blood thinner to dissolve blood clots, improve circulation, and lower blood pressure.
