Nattokinase: Complete Product Guide
What is Nattokinase?
Nattokinase is an enzyme extracted from natto, a traditional Japanese food made from fermented soybeans that has been enjoyed for over 1,000 years. It's now recognized worldwide as a popular choice for everyday heart health support.
Key benefits
- Supports healthy blood circulation
- Supports cardiovascular health
- Helps maintain healthy blood pressure already within a normal range
- Supports overall heart health as you age
How to take Nattokinase
- Serving: 200 mg (4,000 FU) — 2 capsules daily with food
- Bottle: 60 capsules — up to 1 month's supply
- Take at a consistent time each day — many people choose morning
What does FU mean? FU (Fibrinolytic Units) is the standard measure of nattokinase enzyme activity — it tells you the potency, which matters more than the milligram weight. Our serving provides 4,000 FU.
When to expect results
Cardiovascular support builds over time. Take it consistently for at least 2 months as part of your daily routine.
Safety — very important
Do NOT take Nattokinase without your doctor's approval if you:
- Take blood thinners (warfarin/Coumadin, heparin, Plavix, or daily aspirin therapy)
- Take anti-platelet medications
- Have a bleeding disorder
- Are scheduled for surgery within 2 weeks
- Are pregnant or nursing
Also check with your doctor if you take blood pressure medications or have any cardiovascular condition.
Before surgery: stop taking Nattokinase at least 2 weeks before any scheduled procedure and tell your surgeon you've been taking it.
Stop and contact your doctor if you notice unusual bleeding or bruising, blood in urine or stool, or prolonged bleeding from cuts.
Soy allergy note
Nattokinase comes from fermented soybeans. Fermentation typically removes most soy proteins, but if you have a soy allergy, consult your doctor before taking it.
