Nattokinase, also known as subtilisin (hereinafter referred to as NK), is a serine protease produced by Bacillus subtilis natto during the fermentation of natto. It can dissolve thrombi, reduce blood viscosity, improve blood circulation, soften blood vessels and enhance vascular elasticity.
★ Product Features
① Produced via liquid fermentation and nanobiotechnology, enabling precise extraction of active ingredients. The product's kinase activity exceeds 50,000 Fu/g.
② Compared with other thrombolytic drugs, Nattokinase (NK) offers advantages including low cost, high safety, small molecular weight, excellent oral efficacy, strong thrombolytic activity and long duration of action.
③ Optimal reaction temperature: 30–45°C, best performance at 37°C; denatures above 80°C. Optimal pH: 6–9, best at pH 7.4; inactivates below pH 5.
💡 Enzyme Activity Definition: Nattokinase reacts with fibrin to hydrolyze its peptide bonds, changing the solution's absorbance at 275 nm UV light. One activity unit (1 FU) refers to the energy consumed for every 0.01 increase in absorbance at 275 nm.

Effects of Different Factors on Enzyme Activity
Functions & Applications
❤️Nattokinase helps dissolve blood clots and lower blood lipids, making it highly effective in protecting against and supporting cardiovascular and cerebrovascular health.
🌿It supports healthy hormone balance, aids detoxification, improves skin appearance, and assists with weight and fat management.
💪It also offers antioxidant and anti-fatigue benefits, helping to slow down the aging process.
💊Absorbed easily through the intestines, it boosts thrombolytic activity, reduces the risk of heart attack, and supports stronger heart function.
Storage
❄️Keep in a cool, dry and dark place. Storage temperature: below 0°C.
⚠️Prolonged or improper storage may reduce enzyme activity. If exposed to high temperature or humidity, an appropriate increase in dosage is recommended.

Frequently Asked Questions (FAQ)
QWhat is Nattokinase and where does it come from?
ANattokinase (NK) is a serine protease naturally produced by Bacillus subtilis natto during the fermentation process of natto (a traditional Japanese soybean food). It is extracted using liquid fermentation and nanobiotechnology to ensure high purity and potency.
QWhat is the enzyme activity level of your Nattokinase product?
AOur Nattokinase product has a kinase activity exceeding 50,000 FU/g (Fibrinolytic Units per gram), ensuring highly effective thrombolytic performance for health and supplement applications.
QWhat are the main health benefits of Nattokinase?
ANattokinase supports cardiovascular and cerebrovascular health by dissolving blood clots, lowering blood lipids, and improving circulation. It also offers antioxidant, anti-fatigue, hormone-balancing, and skin-improving benefits, and helps reduce the risk of heart attack.
QWhat are the optimal storage conditions for Nattokinase?
ANattokinase should be stored in a cool, dry, and dark environment at temperatures below 0°C. Exposure to high temperatures (above 80°C) or acidic conditions (below pH 5) will cause denaturation and loss of enzyme activity. If storage conditions are suboptimal, increasing the dosage slightly is recommended.
QWhat packing and shipping options are available?
AWe offer flexible packaging from 1kg (aluminum foil bag inside a box) to bulk 25kg drums or cartons. Shipping is available worldwide via EMS, DHL, UPS, FedEx, air freight, or sea freight, with delivery times ranging from 3–7 days (express/air) to 10–35 days (sea).
QDoes your Nattokinase meet international quality and safety standards?
AYes. Our Nattokinase passes rigorous quality testing including physical characteristics, heavy metal limits (USP, AOAC standards), pesticide residue tests, and full microbiological testing (E. Coli and Salmonella negative). All results conform to international standards including GB, AOAC, USP, and FDA BAM methods.
