Nattokinase Plus
Natural nattokinase enzyme from fermented soybeans with an activity of 2000 FU, supplemented with prebiotic inulin – for comprehensive care of a healthy vascular system.
Fermented foods have a tradition spanning more than 2,000 years in Japan. Natto, a natural source of the enzyme nattokinase, is one of these traditional Japanese fermented foods.
How Nattokinase Plus works
Nattokinase is a natural enzyme obtained from the traditional Japanese food natto, which is produced by fermenting soybeans with Bacillus subtilis bacteria. As a proteolytic enzyme, it acts as an organic catalyst that breaks down large protein molecules. It specifically targets the breakdown of fibrin – a protein that plays a key role in the formation of blood clots.

Frequently asked questions
What is nattokinase and what is it used for?+
Nattokinase is a proteolytic enzyme from the Japanese food natto, which is produced by fermenting soybeans with Bacillus subtilis bacteria. It specifically targets the breakdown of fibrin – a protein involved in the formation of blood clots. It is therefore primarily used as natural support for a healthy vascular system and smooth blood circulation.
When is the best time to take nattokinase – morning or evening?+
You can take Nattokinase Plus in the morning or evening – more important than the time of day is taking it on an empty stomach: ½ an hour before a meal or 2 hours after a meal. Ideally, take it at the same time every day.
Why should nattokinase not be taken with food?+
If taken with food, the enzyme would be “used up” digesting dietary proteins. On an empty stomach, it is absorbed into the bloodstream and reaches the tissues, where it acts systemically and breaks down proteins such as fibrin directly in the body.
Can I take nattokinase if I am taking blood-thinning medication?+
Not without consulting your doctor. Nattokinase affects processes associated with blood clotting, so if you are taking anticoagulants or antiplatelet agents, have a blood-clotting disorder or are due to undergo surgery, only take it after consulting your doctor.
How long should I take nattokinase before I see results?+
Nattokinase is suitable for regular, long-term use. For example, in the study by Hsia et al. (2009), changes in fibrinogen levels and other clotting factors were monitored after 2 months of daily use. One pack of Nattokinase Plus lasts for 3 months.
Can nattokinase help during a long flight?+
During long flights and extended periods of sitting or standing, Nattokinase Plus may support blood circulation in the limbs. It is best to take it regularly and, during the journey, drink enough fluids, change position frequently and walk around.
What does 2000 FU mean and why is it important?+
FU (fibrinolytic unit) is a unit that expresses the enzyme’s ability to break down fibrin. With nattokinase, it is the activity that matters, not merely its weight in milligrams – the higher the FU value, the stronger the breakdown of proteins. One Nattokinase Plus capsule contains 2000 FU.
What is the difference between NSK-SD® nattokinase and regular nattokinase?+
NSK-SD® is a brand of certified, pure nattokinase with standardised enzymatic activity and unique authorisation for placement on the EU market. This gives you the assurance that every capsule contains the declared 2000 FU.
Is Nattokinase Plus suitable for vegans and people with a soy allergy?+
It is suitable for vegans – Nattokinase Plus is 100 % vegan, gluten-free and lactose-free, and is also suitable for people with coeliac disease and diabetes. Since nattokinase comes from fermented soybeans, people with a soy allergy should consult their doctor before use.
Is nattokinase also suitable for athletes?+
Yes. Athletes use nattokinase mainly to support blood circulation and faster recovery after exercise. Take it on an empty stomach, away from foods and drinks containing protein, and follow the recommended dose of 1 capsule daily.
