Potential Benefits of Our Organic Nattokinase Capsules

Our nattokinase capsules can help support healthy blood vessels and energy supply. The enzymes and active compounds they contain can work synergistically.

Key potential benefits at a glance:

  • Supports blood flow: Nattokinase has fibrinolytic activity that can break down excess fibrin and thereby support healthy circulation. This may help promote healthy arteries and stable blood pressure. Many people therefore use nattokinase preventively as a “plant-based aid for supporting healthy blood flow.”
  • Supports cellular metabolism: The polyamine spermidine may promote cell-protective processes such as autophagy and support cellular vitality.
  • Supports homocysteine metabolism: Vitamin B9 (folate) contributes to normal homocysteine metabolism, which can have a positive effect on cardiovascular health.
  • Antioxidant effects: Soy isoflavones have antioxidant properties and may help modulate inflammatory processes, thereby supporting vascular health.
  • Gut and mineral support: Probiotic Bacillus subtilis natto cultures support a balanced gut microbiome, while phosphorus contributes to normal energy metabolism and iron is important for oxygen transport in the blood.

These potential mechanisms of action make our dietary supplement a unique product that harnesses the power of nature to support the body. For even more comprehensive supplementation, you can also find other high-quality dietary supplements for gut health or natural antioxidant supplements such as OPC drops or vitamin E, which can be easily combined with the tablets.

Note: As many of the effects described are still being scientifically investigated, no definitive conclusions can currently be drawn. Find out more about the latest research and the potential effects of nattokinase in our detailed blog article.

More Than Standard

Made with love by hand

While many companies rely on mass production and machinery, we take a different approach: our nattokinase tablets are genuinely handcrafted from carefully fermented organic soybeans sourced directly from Japan.

Purity, variety and trust – far more than just nattokinase

In addition to nattokinase, our tablets contain a natural spectrum of valuable nutrients and compounds from fermented soybeans (natto), including vitamin K2 (MK-7), vitamin B9 (folic acid), spermidine, soy isoflavones, probiotic bacteria, as well as naturally occurring phosphorus and iron. They are handcrafted under controlled food hygiene conditions. The nattokinase extract is gently freeze-dried to preserve the sensitive enzyme activity as effectively as possible, without a capsule shell or artificial additives. To ensure consistently high product quality, we also have every batch analyzed by an independent laboratory.

We believe in authentic natto

Our nattokinase does not come from industrially produced isolates, but from genuine fermented natto made with the original Bacillus subtilis natto, as traditionally used in Japan for generations.

Nattokinase

Die Bestellung ist recht schnell und gut bei uns in Belgien angekommen.

Die Presslinge sind wahrscheinlich vom Transport zerfallen und mussen jetzt Nattokinase mit ein Teelöffel einnehmen.
Es war sonst einfacher zum correct einnehmen.

Danke

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.

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.

Yes, our Nattokinase capsules are 100% plant-based and are therefore suitable for both vegetarians and vegans. They are made exclusively from fermented organic soybeans and contain no animal-derived ingredients. They are also gluten-free and lactose-free.
