At 59 years old I have had growing concerns about my arterial health. As with all these "supplements" I was sceptical at first but felt there was something interesting about this particular company so I did my own extensive research and thought I'd order 3 months supply considering what I now know about the health benefits of the Natto plant. I am only three weeks in and I can genuinely "feel" the benefits already. My breathing is better, I'm already feeling more "awake" and I can not recommend Nattokinase enough!
