Frequently Asked Questions About Nattovena


What is Nattovena?
Nattovena is a high‑potency nattokinase supplement from Arthur Andrew Medical. Each capsule delivers 4,000 fibrinolytic units (FUs) to support healthy circulation, normal blood viscosity, and the natural breakdown of excess fibrin.
What does nattokinase do?
Nattokinase is an enzyme derived from the traditional Japanese food natto. It helps the body break down fibrin, a protein involved in blood clotting and tissue repair. By supporting normal fibrin levels, it promotes smooth, healthy circulation.
How is Nattovena different from other nattokinase supplements?
Nattovena provides double the potency of standard nattokinase formulas (4,000 FUs per capsule). It’s also allergen‑free, highly purified, and produced using the same microorganism used in traditional natto fermentation.
What are the main benefits of Nattovena?
  • Supports healthy circulation
  • ​​Promotes normal blood viscosity
  • Helps break down excess fibrin
  • Supports cardiovascular wellness
  • Provides high‑strength enzyme activity for enhanced fibrin support
Who typically uses Nattovena?
People looking to support circulation, cardiovascular health, balanced fibrin levels, or recovery processes often choose Nattovena. It’s also popular among those seeking a clean, high‑potency enzyme formula.
How do I take Nattovena?
Take with 8 oz of water on an empty stomach:
  • Maintenance: 2 capsules daily
  • Increased support: 4 capsules daily
  • Therapeutic: 6 capsules daily
Can I take Nattovena with other supplements?
Yes, Nattovena is commonly taken alongside other enzyme formulas such as Neprinol or Serretia. However, individuals on blood‑thinning medications should consult a healthcare professional before use.
Is Nattovena safe?
Nattovena is generally well‑tolerated and free of common allergens. As with any enzyme supplement, individuals with medical conditions or those taking medications should consult their healthcare provider.
Does Nattovena contain soy or gluten?
No. Nattovena is soy‑free, gluten‑free, dairy‑free, and contains no artificial ingredients.
Is Nattovena vegan?
Yes. Nattovena contains vegan‑friendly enzymes and plant‑based capsules.
Can I take Nattovena with food?
For best results, take Nattovena on an empty stomach, which allows the enzymes to enter the bloodstream rather than digest food.
How long does it take to notice results?
Many users report benefits within 1–4 weeks, depending on dosage and individual health needs. Enzyme activity builds gradually, so consistent daily use is recommended.
