Plasmanex1®

Support Healthy Circulation—Where It Matters Most

Clots kill. Plasmanex1® helps keep your blood flowing and your heart protected—especially as you age, travel, or live with risk factors like obesity or poor circulation. Powered by Bacillopeptidase F, it promotes balanced coagulation without the harsh effects of drugs.

  • Improves blood circulation and extremity warmth*
  • Reduces clot complications from travel, weight, or inactivity*
  • Safe to use with blood thinners*

Why it's superior to nattokinase: Better bacterial strain, higher potency, targets PAI-1—not just fibrinogen—for smarter clot control.*
