Description

Our 100% natural organic-quality tablets are made exclusively from non-GMO soybeans grown in Japan and shaped into small tablets in Europe – completely without capsule shells.

Gentle fermentation & maximum enzyme activity: The soybeans are fermented with Bacillus subtilis natto and then freeze-dried to preserve their full natural enzyme power. Each tablet contains approximately 1400–1600 FU of nattokinase. We strictly avoid all additives.

A staple of Japanese daily life: Natto is more than just a food in Japan – it is a traditional breakfast dish, often served over rice, and an integral part of many households. This centuries-old fermentation method has made natto a symbol of health and longevity.

Tradition backed by science: Modern research confirms what Japanese tradition has long valued – natto is considered a “secret to longevity” thanks to its richness in bioactive compounds, especially nattokinase with its clot-dissolving and blood pressure–lowering properties.

Practical packaging: For quality and safety, our tablets come in resealable plastic containers – glass jars are unsuitable for the special pressure-seal closure.

Enjoy a completely natural supplement that supports overall vitality – from cardiovascular health to general well-being!

Benefits

  • Heart & blood vessels:

    Nattokinase, the key enzyme in natto, may help lower blood pressure and protect blood vessels, supporting healthy circulation.
  • Natural “blood thinner”:

    With its fibrinolytic properties (2–4, 38), nattokinase can help dissolve blood clots, acting as a natural blood-thinning agent. Many people take it as a preventive measure for heart and vascular health. You also benefit from other naturally occurring nutrients from natto fermentation, including vitamin K2 (MK7), soy isoflavones, and probiotics.
  • Nattokinase & spike proteins:

    A Japanese study 'Degrading effect of nattokinase on the spike protein of SARS-CoV-2' suggests nattokinase may help break down harmful spike proteins, underlining its significant health potential.

For best results, take continuously for at least 3 months to experience the full benefits.

More than just standard

Made with love by hand

While many companies focus on mass production and machines, we take a different approach: our nattokinase tablets are made entirely by hand – from carefully fermented organic-quality soybeans sourced directly from Japan.

Purity, variety and trust – far more than just nattokinase

In addition to nattokinase, our tablets naturally contain a full spectrum of valuable compounds from fermented soybeans (natto) – including Vitamin K2 (MK-7), Vitamin B9 (folate), spermidine, soy isoflavones, probiotic bacteria, as well as naturally occurring phosphorus and iron. Production takes place entirely by hand under strictly monitored food hygiene conditions. The nattokinase extract is gently freeze-dried to preserve its delicate enzymatic activity – without capsules and without artificial additives. For consistently high quality, every batch is also tested by an independent laboratory.

We choose authentic natto

Our nattokinase is not derived from industrial isolates but from genuine fermented natto – made with the original Bacillus subtilis natto used in Japan for generations.

Bewertung von Margit T.

















Ich habe mich schon vor der Bestellung telefonisch beraten lassen und war sehr zufrieden. Die Lieferung ist sehr flott eingetroffen und die Presslinge sind in gutem Zustand angekommen. Ich habe mich für dieses Produkt entschieden, da die Presslinge frei von Zusatzstoffen und in Bioqualität sind. Über die Wirkung kann ich noch keine Aussage treffen, bin aber zuversichtlich.

Bewertung von Sabine B.

Schnelle Lieferung. Sehr gut verträglich. Super finde ich, dass kein unnötiger Überzug und damit verbunden auch keine weiteren Stoffe verwendet werden, die man nicht im Körper haben will, wie dies so häufig bei anderen Tabletten der Fall ist. Wer es nicht im Ganzen schlucken möchte, kann die Tabletten einfach zerkleinern.

Beste Natokinase

Ich kenne einige Natokinase Produkte aber dieses ist das erste das als Pressling nichts verschleiert was man einnimmt. Sie sind leicht zu schlucken, haben einen neutralen Geschmack und riechen angenehm.
Ich nehme es da ich immer wieder Probleme mit dem Nacken habe und dadurch ein Ohr zu geht. Es ist noch nicht alles in Ordnung aber es wird besser und besser.
Dieses ist das erste mal , das ich ein Produkt bewerte da ich absolut überzeugt bin. Danke für die hervorragende Qualität

Frequently Asked Questions About Our Organic Nattokinase Capsules

Do you have more questions about our nattokinase capsules? In this short FAQ, we’ve summarized everything about effects, usage, and key properties:

Our nattokinase tablets are made from 100% fermented organic soybeans, traditionally used in Japanese cuisine to produce natto. Thanks to gentle fermentation, all natural compounds are preserved, including nattokinase, spermidine, vitamin B9, isoflavones, probiotic cultures, phosphorus, and iron.

Nattokinase may support heart and cardiovascular health in a natural way. The enzyme promotes blood flow, contributes to normal vascular function, and supports metabolism. By helping break down fibrin, it may reduce the tendency for clot formation and positively influence the risk of cardiovascular conditions such as heart attack or stroke.

The recommended intake is two tablets per day. For optimal absorption, take them on an empty stomach. Whether in the morning or evening is flexible; consistency is what matters. For noticeable effects, continuous use for at least three months is recommended.

Because we intentionally avoid additives and binding agents in our nattokinase capsules, they are more fragile than conventional products and may break during transport or storage. To minimize this risk, tablet hardness is continuously monitored, and the product is packaged in durable containers with a special closure. However, the effectiveness remains unchanged even if the tablets break. In this case, simply mix one level teaspoon of the powder—equivalent to one tablet—into sufficient water and drink it.

Use the product exactly as directed on the packaging and do not exceed the recommended intake. Discontinue use at least two weeks before any planned surgery. If you are taking blood thinners or have clotting disorders, consult your doctor before use. The same applies during pregnancy or breastfeeding.

Ja, unsere Nattokinase Kapseln sind 100 % pflanzlich und somit vegan. Sie bestehen ausschließlich aus fermentierten Bio-Sojabohnen und enthalten keine tierischen Zusatzstoffe. Zudem sind sie ebenfalls gluten- und laktosefrei.

Nattokinase + D3

Content: 120 Pressings (€0.33 / 1 Pressings)

Regular price: From €39.90

As we age, the natural elasticity of blood vessels decreases, blood becomes thicker, and blood pressure rises. Our tablets combine two well-researched principles with potential complementary effects via different pathways – nattokinase from traditional natto fermentation and vitamin D3 (cholecalciferol) in a physiological dosage, all from purely ecological sources. Our 100% natural tablets are – as always – made exclusively from non-GMO soybeans originally grown in Japan, then carefully formed into small tablets in Europe – without any capsule shell. New to the formula is the addition of vitamin D3 (cholecalciferol) in an optimal dosage for the body. Gentle fermentation and maximum enzyme activity: The beans are fermented with Bacillus subtilis natto and then freeze-dried. This fully preserves the natural enzyme activity of approx. 1400–1600 FU of nattokinase per tablet. We strictly avoid any additives. Rooted in Japanese daily life: In Japan, natto is much more than just a food. It is considered a classic breakfast dish – usually served fresh over rice – and is an essential part of many households. The centuries-old fermentation tradition has made natto a symbol of health and longevity to this day. Scientifically supported traditional knowledge: Recent reviews confirm popular belief. In Japan, natto is even called a “secret for longevity” because it is rich in bioactive compounds – especially nattokinase with its thrombolytic and blood pressure-lowering properties. Practical packaging: For quality and safety reasons, we ship our tablets in resealable plastic containers – glass containers are unsuitable for the special pressure seal. Enjoy a fully natural product that can support your well-being in many ways – from heart health to overall vitality! Effects Heart & Vessels:Nattokinase is an enzyme derived from fermented soybeans (natto). In naturopathy, it has long been valued for its supportive effects on the cardiovascular system. Studies suggest that nattokinase may help regulate blood pressure naturally and maintain the elasticity of blood vessels. Combined with vitamin D3, which supports the normal function of the heart and blood vessels, it creates a meaningful synergy for healthy circulation. Natural “blood thinner”:Nattokinase has fibrinolytic properties (2, 3, 4, 38): it can dissolve fibrin, a key component of blood clots. This makes the enzyme act like a natural blood thinner – but without the risks of synthetic anticoagulants. Health-conscious individuals use nattokinase preventively to support normal blood circulation. The natural composition from natto fermentation also provides valuable accompanying compounds: vitamin K2 (MK-7), which helps maintain normal blood vessels, plus soy isoflavones and probiotic cultures. Vitamin D3 – support for immunity, bones, and muscles:Vitamin D3 fulfills numerous vital functions in the body. It contributes to normal immune system function and thus supports the body’s natural defense against pathogens. It is also essential for maintaining healthy bones and teeth – partly because it enables the normal absorption and utilization of calcium and phosphorus and contributes to balanced calcium levels in the blood. Vitamin D3 also supports normal muscle function and plays a role in cell division – a key biological process essential for growth and regeneration. Especially during months with little sun or when the body’s own production is limited, targeted supplementation with vitamin D3 can help meet needs and promote balance. Nattokinase against spike proteins:A Japanese study 'Degrading effect of nattokinase on the spike protein of SARS-CoV-2' suggests that nattokinase may even break down harmful spike proteins (such as those found in the body after mRNA vaccinations). This highlights the enzyme’s significant health potential. Dosage Recommended intake Take 2 tablets daily with 200 ml of water For best results, we recommend continuous use for at least 3 months to allow the full effect to develop Not suitable for individuals taking anticoagulant medications (blood thinners) Discontinue use at least 2 weeks before planned surgery Food supplement Do not exceed the recommended daily intake.
