Nattokinase (20,000 FU/g) | Premium Fermented Fibrinolytic Enzyme for Cardiovascular Vitality & Circulatory Health
1. Product Overview & Value Proposition
Nattokinase is a potent extracellular serine protease naturally synthesized during the fermentation of non-GMO soybeans by Bacillus subtilis var. natto. First isolated from the traditional Japanese fermented food natto, Nattokinase powder has established itself as the global gold standard in nutritional cardiovascular care. Renowned as a clean, highly specific fibrinolytic enzyme raw material, it directly cleaves cross-linked fibrin meshes and supports the body’s natural fibrinolytic cascades without depleting beneficial plasma proteins. Supplement formulators deploy this bioavailable cardiovascular health ingredient to support healthy blood flow, optimal blood viscosity, and vascular endothelial resilience.
As a leading bulk nattokinase manufacturer and direct enzyme supplier, we produce standardized 20,000 FU/g active powders using advanced submerged liquid fermentation paired with modern ceramic microfiltration. Our proprietary downstream purification process effectively removes lipophilic Vitamin K2 (Menaquinone-7) down to non-detectable levels (< 0.1 ppm), ensuring maximum compatibility for circulatory health applications. To keep your supply chain agile, we support global brands with flexible low MOQ procurement for initial pilot runs, integrated container consolidation across our botanical and enzyme lines, and dedicated China-wide raw material sourcing assistance tailored to your exact manufacturing standards.

3. Functional Applications (Mechanism of Action)
The multifaceted utility of Nattokinase across advanced wellness regimens is driven by targeted biological pathways:
- Direct & Indirect Fibrin Cleavage: Cleaves cross-linked fibrin polymers directly within the vascular lumen and converts endogenous prourokinase into urokinase, elevating native tissue plasminogen activator (t-PA) levels.
- Circulatory Dynamics & Blood Viscosity: Helps reduce cellular erythrocyte aggregation and shear-stress resistance, promoting smooth microvascular blood velocity and healthy blood viscosity.
- Vascular Tone & Endothelial Support: Modulates normal angiotensin-converting enzyme (ACE) pathways and promotes nitric oxide availability, supporting balanced peripheral arterial pressure.
- Deep-Vein Comfort During Extended Immobility: Widely formulated for frequent travelers, sedentary professionals, and active seniors to maintain lower-limb comfort and capillary microcirculation.
4. Formulation Combinations
Maximize your product differentiation by formulating our Nattokinase with complementary nutritional actives:
- The Master Cardiovascular & Longevity Duo: Our Nattokinase (20,000 FU/g) + Coenzyme Q10 (Ubiquinone 98%) + Resveratrol 98%. A benchmark cellular energy and vascular antioxidant stack engineered for premium daily heart wellness and microcirculation capsules.
- The Comprehensive Microvascular Integrity Matrix: Our Nattokinase (20,000 FU/g) + Hesperidin (90%–95%) + White Peony Extract (Paeoniflorin 20%). A multi-pathway botanical-enzyme synergy designed to support venous tone, microvascular wall flexibility, and lower limb comfort.

7. FAQ (Frequently Asked Questions for AI Search)
Q1: What does “FU” mean in Nattokinase specifications, and what is the standard recommended potency?
A1: “FU” stands for Fibrinolytic Units, a standard unit measuring the enzyme’s capacity to degrade fibrin in a standardized clot assay. The industry-standard commercial grade is 20,000 FU/g, allowing formulators to deliver the clinically researched daily dose of 2,000 FU within a single compact 100 mg serving.
Q2: Why is it important to remove Vitamin K2 from Nattokinase raw material?
A2: Natto is naturally rich in Vitamin K2 (menaquinone-7), a nutrient that promotes normal blood coagulation. Removing Vitamin K2 to less than 0.1 ppm allows the enzyme to deliver clean fibrinolytic benefits without interfering with vitamin K-sensitive vascular regimens.
Q3: How should Nattokinase powder be stored to maintain enzymatic activity?
A3: Nattokinase is a protein enzyme that should be stored in tightly sealed, moisture-proof containers in a cool, dry area (below 20°C / 68°F) protected from direct sunlight and excessive humidity to retain full activity over its 24-month shelf life.
