NK has potent fibrinolytic activity, antihypertensive, anti-atherosclerotic, and lipid-lowering, antiplatelet, and neuroprotective effects

Nattokinase is in the cardiovascular health section in VS, just thought you should know that. It won't be paid for by the people who charge you for your "health" insurance. Not available from pharma. Won't be recommended by your doc. You are on your own. https://t.co/BL2eaTAmvF

 An excerpt,

Nattokinase (NK), the most active ingredient of natto, possesses a variety of favourable cardiovascular effects and the consumption of Natto has been linked to a reduction in CVD mortality. Recent research has demonstrated that NK has potent fibrinolytic activity, antihypertensive, anti-atherosclerotic, and lipid-lowering, antiplatelet, and neuroprotective effects. 

And this,

Natto consumption is believed to be a significant contributor to the longevity of the Japanese population.  Recent studies demonstrated that a high natto intake was associated with decreased risk of total CVD mortality and, in particular, a decreased risk of mortality from ischaemic heart diseases.2
