Nattokinase Supplement 4,000 FU Servings, 120 Capsules (Derived from Japanese Natto) Systemic Enzymes for Cardiovascular and Circulatory Support by Double Wood

I am a believer now. Been taking this for a bit under a year and just had bloodwork done yesterday to find that my cholesterol levels are healthier than I could have ever thought possible. Every single marker is so far in to the green that it's almost concerning how good they are. Legitimately looking forward to seeing my doctor's reaction to this.

This has helped a lot with relieving my heart palpitations and the sense of pressure I feel in my chest, especially when I'm sleeping. Highly recommend :)

I took this for two weeks before getting a DOT physical, always had issues with blood pressure and the eye exam. Well the doctor said to me, “your blood pressure is under control and you aced the eye test don’t know how you did that” that works for me.

Sealed well and no issues. I dont know about how quality it is or how effective it is but ive been taking it for the past few months daily and have had no issues
