How Nattokinase supports heart
Nattokinase is a supporting nutrient for heart support. Nattokinase is a fibrinolytic enzyme from fermented soybeans (natto). A 2023 meta-analysis of 6 RCTs found significant reductions in systolic BP (-3.45 mmHg) and diastolic BP (-2.32 mmHg). Single-dose studies confirm enhanced fibrinolytic activity via elevated D-dimer.
Effective dosing
Most evidence supports 2000–4000 fu of nattokinase daily. 2,000-4,000 FU/day for cardiovascular support. Meta-analysis of 6 RCTs (546 subjects) showed significant BP reduction at 2,000 FU. Higher doses (10,800 FU) may be needed for lipid effects. Products below this range may not deliver meaningful results.
Clinical research
