FINE Natto Kinas is a powerhouse blood health supplement from the Japanese fermented soybean "natto" with the additional essential enzyme "Nattokinase", extracted from natto, plus fermented black onion, onion skin, and garlic extracts, all noted for positive effects on blood and veins. Nattokinase may help to make blood so healthy it does not clot in the veins. Strokes or clots may be avoided by strengthening the ability of the blood to dissolve clots as they form in the veins and arteries (fibrinolytic factor) as well as to help it to remove plaque in veins and arteries without thinning.
