**Nattokinase** at 4,000 FU per capsule — right at the top of the clinically studied range for cardiovascular support. A meta-analysis of six RCTs found this dose range can modestly reduce blood pressure and enhance your body's natural ability to break down fibrin, the protein involved in blood clot formation. The NSK-SD branded form used here is vitamin K-free, which matters if you're on blood thinners.
The formula also includes a blend of digestive enzymes alongside the nattokinase, though the **Bromelain** at 96 GDU is well below the 1,200+ GDU range studied for anti-inflammatory benefits — at this dose, it's contributing to digestion rather than joint or inflammation support.
The directions suggest taking this on an empty stomach, which is important — nattokinase's fibrinolytic activity is best studied when taken away from food. If you're using blood-thinning medication, check with your doctor before adding this to your routine.
