Product Description
Natto Fermented Powder is produced through solid-state or submerged fermentation of non-GMO soybeans using Bacillus subtilis natto. The resulting serine protease - nattokinase (NK) - is extracted, purified, and spray-dried into a stable, odor-neutralized powder. Each gram delivers a precisely standardized enzyme activity measured in Fibrinolytic Units (FU), the internationally accepted benchmark for nattokinase potency.
At Jiuyuan Bio, we supply Natto Fermented Powder across a full activity range - from 2,000 FU·g⁻¹ for entry-level formulations to 20,000 FU·g⁻¹ for high-potency cardiovascular products. Every batch is verified by the JHFA fibrin plate method at 37°C, pH 7.4 - the gold standard for nattokinase activity testing.

High-Purity Crystalline Grade
For pharmaceutical and clinical research applications, we offer a crystalline-grade nattokinase with:
- Nattokinase purity ≥80% (batch crystallization process)
- Verified by SDS-PAGE + HPLC size-exclusion chromatography
- Suitable for API-level formulation and pharmacokinetic studies
Manufacturing Process
Transparency in production is non-negotiable for regulated markets. Here's how our Natto Fermented Powder is made:
1. Raw Material Selection Non-GMO soybeans sourced from Heilongjiang province - China's premier non-GMO soybean belt. Each incoming lot undergoes PCR-based GMO screening and allergen verification before entering production.
2. Strain Preparation Authenticated Bacillus subtilis natto seed culture is prepared under controlled conditions. Strain identity is confirmed by 16S rRNA sequencing for every production cycle.
3. Fermentation
- Solid-state fermentation: Traditional method; higher enzyme expression per gram of substrate
- Submerged liquid fermentation: Scalable, continuous production; tighter batch-to-batch consistency
- Fermentation parameters - dissolved oxygen, pH, temperature - are monitored in real time via in-line sensors
4. Extraction and Purification Fermented biomass undergoes aqueous extraction followed by multi-stage membrane filtration (ultrafiltration + nanofiltration). This step removes Bacillus cells, polyglutamic acid (PGA), and residual soy matrix.
5. Vitamin K2 Removal (Optional) For markets requiring K2-free product - particularly for customers on anticoagulant therapy - an additional adsorption step eliminates vitamin K2 to below detectable limits.
6. Spray Drying and Deodorization The purified enzyme solution undergoes spray drying with food-grade excipients. A deodorization step eliminates the characteristic natto odor - critical for consumer-facing supplement formats.
7. Standardization and Blending Final powder is blended to target FU activity. Every batch is assayed by the JHFA fibrin plate method before release.
8. Packaging 25 kg fiberboard drums with double PE inner bags and desiccant sachets. Cold-chain shipment at 2–8°C is recommended for orders above 100 kg.

Why FU Matters More Than Milligrams
This is a point many buyers miss. Milligram dosage is meaningless for enzyme ingredients. A product labeled "500 mg nattokinase" tells you nothing about potency. What matters is the FU activity per serving.
The research-supported dose range for cardiovascular applications is 2,000–4,000 FU per day, as referenced in the landmark NATTOPHARMA-funded clinical trials and the 2021 meta-analysis published in Nutrients (Weng et al., 2021).
Always specify FU activity - not milligrams - in your product specifications and label claims.
Product Benefits & Applications
1. Main effects

Potential Fibrinolytic Activity
Nattokinase, an enzyme present in Natto powder, has demonstrated in vitro and some in vivo evidence of fibrinolytic activity, suggesting a potential role in the breakdown of fibrin, a component of blood clots. Further well-controlled human studies are needed to fully elucidate its efficacy, speed of action, and duration in various physiological contexts. While it may influence thrombus-decomposing enzymes, more research is required to confirm the specific mechanisms and clinical significance of these interactions.

Potential Role in Blood Pressure Management:
Some research suggests that long-term consumption of nattokinase may contribute to modest reductions in blood pressure in individuals with hypertension. However, the evidence is not conclusive, and the magnitude of the effect can vary. Individuals with high blood pressure should consult with healthcare professionals for appropriate management strategies.

Antioxidant Properties:
Natto powder contains compounds like isoflavones and vitamin E, which exhibit antioxidant activity in vitro by neutralizing free radicals. The extent to which these properties provide significant protection against oxidative stress and support cellular health in vivo requires further investigation in human studies.

Potential Influence on Blood Lipids:
Preliminary studies indicate that components in Natto powder may have a role in modulating blood lipid profiles, potentially contributing to lower LDL cholesterol and increased HDL cholesterol levels. However, more robust clinical trials are necessary to confirm these effects and their clinical relevance.

Potential Support for Digestive Health:
The presence of Bacillus subtilis var. natto spores in Natto powder may contribute to gut health by potentially acting as a probiotic, helping to maintain intestinal balance. Further research is needed to determine the extent of its impact on digestive and immune function.

FAQ
Q1: What is the difference between Natto Fermented Powder and nattokinase extract?
Natto Fermented Powder is the broader category - it can refer to whole-ferment powder (containing Bacillus cells, PGA, K2, and nattokinase) or purified nattokinase extract. Our product is a purified, standardized nattokinase extract in powder form, not a whole-food ferment. This distinction matters for dosing accuracy, label claims, and regulatory compliance.
Q2: Why does nattokinase need enteric delivery?
Nattokinase is a protein-based enzyme. Gastric acid (pH ~1.5–2.5) rapidly denatures it before it reaches the small intestine. Enteric coating - whether on softgels or hard capsules - protects the enzyme through the stomach and releases it at intestinal pH (≥6.0), where absorption occurs. Formulating without enteric protection significantly compromises bioavailability.
Q3: How should FU activity be declared on the label?
In the US, the FDA expects enzyme activities to appear on the Supplement Facts panel in the unit relevant to the enzyme's function. For nattokinase, FU (Fibrinolytic Units) is the accepted unit. Declaring only milligrams without FU activity is considered insufficient for consumer transparency and may draw regulatory scrutiny.
Q4: Is your nattokinase derived from non-GMO soybeans?
Yes. All production batches use non-GMO soybeans sourced from Heilongjiang province, China. Non-GMO status is verified by PCR testing on every incoming raw material lot. Non-GMO certificates are available with each shipment.
Q5: Can nattokinase be combined with other cardiovascular ingredients?
Yes - and it's often more effective in combination. Well-documented synergistic pairings include:
Red yeast rice (monacolin K): Complementary lipid-lowering + fibrinolytic action
Coenzyme Q10: Mitochondrial support alongside vascular health
Omega-3 fatty acids: Antiplatelet + fibrinolytic dual mechanism
Magnesium: Vascular tone regulation
Note: Customers taking warfarin or other anticoagulants should consult a physician before use. Use K2-free grade to eliminate any potential vitamin K interaction.
Q6: What is the recommended storage condition during shipping?
For short-distance or air freight under 72 hours, ambient temperature with desiccant is acceptable for the 2,000–5,000 FU grades. For bulk sea freight or high-activity grades (≥10,000 FU), cold-chain shipping at 2–8°C is strongly recommended to preserve enzyme activity over transit. We provide stability data to support your logistics planning.
Q7: Do you offer white-label or custom-specification production?
Yes. We support:
Custom FU activity (any grade between 2,000–20,000 FU·g⁻¹)
Custom particle size and flowability specifications
K2-free or K2-retained grades
Organic-certified substrate options (on request)
Private label documentation including custom CoA headers
Contact our technical team to discuss your specification requirements.
Q8: What regulatory pathway applies for selling nattokinase in the EU?
Nattokinase falls under EU Novel Food Regulation (EU) 2015/2283 because it was not consumed to a significant degree in the EU before May 1997. Brands selling nattokinase supplements in the EU must either hold a Novel Food authorization or demonstrate substantial equivalence to an authorized product. We can provide supporting technical documentation to assist your regulatory submission.
