This is a systemic enzyme formula aimed at circulation and healthy blood flow, built around two proteolytic enzymes measured in activity units rather than milligrams. The **Nattokinase** delivers 2,000 FU per capsule — exactly the dose where a meta-analysis of 6 RCTs found modest blood pressure reductions, so you're sitting right at the effective minimum. It works by supporting your body's natural breakdown of blood clots, which is the strongest evidence-backed reason to take it.

The **Serrapeptase** is dosed at 40,000 SPU, the bottom of the 40,000–120,000 SPU range used in trials, where the typical research dose runs closer to 60,000 SPU daily. Its evidence is thinner — mostly smaller, older studies for post-surgical swelling and sinus congestion — so treat this as a secondary, more speculative ingredient rather than your reason to buy.

One thing you genuinely need to know: nattokinase has measurable clot-thinning effects, so if you're on blood thinners or have a bleeding condition, check with your doctor before using it. The formula also contains soy. At one capsule a day you're getting the minimum effective nattokinase dose and a light serrapeptase dose — workable for general circulatory support, but you'd want a higher SPU count if serrapeptase is your actual target.
