Pure Encapsulations NSK-SD Nattokinase — the researched Japanese nattokinase
NSK-SD is the nattokinase strain from Japan Bio Science Laboratories that the human circulation studies used — standardized to 2,000 fibrinolytic units per 100 mg capsule, with vitamin K removed so it doesn't push clotting the other way. Pure Encapsulations delivers it in a small vegan capsule with nothing else.
Who I reach for it with: healthy blood flow and clotting support; sluggish circulation, cold hands and feet; cardiovascular protocols alongside omega-3; the fibrin side of chronic-inflammation work.
What makes it different: single-ingredient, activity-standardized NSK-SD; vitamin K2-free; small easy-to-swallow capsules; Pure Encapsulations' hypoallergenic standard.
Protocol fit: pairs with Ultra Omega-3 and Magnesium Glycinate in cardiovascular protocols. Designs for Health Natto-Serrazime adds serrapeptase for the tissue-cleanup side.
