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, with the best performance at 37°C; denatures and inactivates above 80°C. Optimal reaction pH: 6–9, with the best performance at pH 7.4; inactivates below pH 5.
💡 Enzyme Activity Definition: Nattokinase reacts with fibrin to hydrolyze the peptide bonds of fibrin. The hydrolysis reaction changes the absorbance of the solution at 275 nm of ultraviolet light. One activity unit (1 FU) refers to the energy consumed for every 0.01 increase in the absorbance value 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 in the body, 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)
Q
What is Nattokinase and where does it come from?
A
Nattokinase (NK) is a serine protease naturally derived from Bacillus subtilis natto during the fermentation of soybeans into natto. It is known for its potent thrombolytic properties and cardiovascular benefits.
Q
What is the enzyme activity level of your Nattokinase product?
A
Our Nattokinase is produced via liquid fermentation and nanobiotechnology, achieving a kinase activity exceeding 50,000 Fu/g, ensuring high potency and consistent quality.
Q
What are the optimal storage conditions for Nattokinase?
A
Nattokinase should be stored in a cool, dry, and dark environment at temperatures below 0°C. Exposure to high temperatures or extreme pH conditions will cause denaturation and loss of enzyme activity.
Q
What packaging options are available for bulk orders?
A
For 1 kg orders, the product is packed in a bag/kg with a double plastic bag and aluminum foil bag inside a box. For 10 kg, 25 kg or larger quantities, drums or cartons with 2 layers of plastic bag inside are used.
Q
How long does delivery take and what shipping methods are available?
A
For shipments up to 100 kgs, delivery via EMS, DHL, UPS, or FedEx typically takes 3–7 business days door-to-door. For orders over 100 kgs, air freight or sea freight options are available.
Q
What quality certifications and testing standards does your Nattokinase meet?
A
Our Nattokinase undergoes comprehensive testing including physical characteristics, heavy metals, pesticide residues, and microbiological tests. All results conform to international quality standards with no detectable pathogens.
