Hi MJ. Good to hear you're doing better.
I had diabetes related neuropathy and blood flow issues in my legs, but since I started taking nattokinase 4 years ago I haven't had any problems. Hardly ever have tingles in my feet now, no blood flow/clotting issues, and my hair has regrown on my lower legs. Here's a link with some info -
