Nattovena® — Double-Strength Pure Nattokinase
Nattovena is one of the most potent pure nattokinase supplements available, delivering 4,000 fibrinolytic units (FU) per capsule — double the strength of standard nattokinase products. Made from a traditional Japanese fermented soybean food called natto, it’s naturally acid-stable, so it works without needing a special enteric coating.

How It Works
Fibrin is a protein that plays a key role in blood clotting and wound healing. As the body ages, fibrin levels can rise and natural fibrin-clearing activity (via the enzyme plasmin) may slow down, which is one factor linked to circulatory sluggishness.*
Nattokinase is a fibrinolytic (fibrin-degrading) enzyme first identified in natto, a fermented soybean dish, through the activity of the bacterium Bacillus subtilis. Nattovena provides a concentrated, pharmaceutical-grade form of this enzyme to support the body’s normal fibrin balance and circulatory health.*
Nattovena may help support:
- Healthy blood viscosity and normal circulation*
- Blood pressure levels already within a normal range*
- Post-exercise muscle recovery*
- Joint comfort associated with healthy circulation*

FAQ
What makes Nattovena different from other nattokinase supplements? Nattovena provides 4,000 FU per capsule, roughly double the potency of many standard nattokinase products, so fewer capsules are needed for the same activity level.
Do I need to take Nattovena with food? No — nattokinase is naturally acid-stable, so Nattovena can be taken on an empty stomach without a special coating.
Is Nattovena vegan and allergen-free? Yes. It’s vegan, non-GMO, kosher, and free of dairy, gluten, and soy.
Can I take Nattovena with other medications? Nattovena should not be combined with blood-thinning or anticoagulant medications without your doctor’s approval. Always consult a healthcare provider before starting any new supplement.
How long before I notice a difference? Individual results vary. As with most enzyme supplements, consistent daily use over several weeks is typically recommended — talk to your healthcare provider about what to expect.
