Product information "Nattokinase"
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.

What is Heilnatura Nattokinase and how is it produced?
Our organic-quality nattokinase is made from soybeans grown in Japan, then gently freeze-dried to preserve maximum enzyme activity.
The beans are non-GMO and come from controlled cultivation. They are fermented exclusively with Bacillus subtilis natto.
Natto itself is a traditional Japanese national dish that has been valued for centuries as a nutrient-dense “samurai breakfast”.
Each tablet provides approx. 2.5 g Organic Natural Natto. It is 100% natural and free from additives or fillers, so in addition to the enzyme nattokinase it also retains vitamin B9, spermidine, soy isoflavones, probiotic bacteria, phosphorus and iron.
The result is a pure, high-quality product that consistently meets natural and quality standards.
What benefits can nattokinase offer for my health?
Cardiovascular diseases, especially ischemic heart disease, remain the world’s leading cause of death and are often underestimated according to WHO analyses. Healthy blood flow and resilient vessels are essential. This is where our natto tablet in organic quality helps, naturally and on several fronts:
- Natural blood flow support The enzyme nattokinase has fibrinolytic activity. It helps break down excess fibrin, supports normal blood fluidity, and may promote healthy blood pressure and flexible arteries. Many health-conscious people therefore use nattokinase preventively as a “plant-based blood-thinning” option.
- Comprehensive nutrient complex from natto fermentation Gentle organic fermentation preserves all relevant accompanying compounds, including
- vitamin B9 (folate), which contributes to normal homocysteine metabolism
- the polyamine spermidine, which supports cell-protective autophagy processes
- soy isoflavones with antioxidant and inflammation-modulating properties
- probiotic Bacillus subtilis natto cultures, which help stabilize the gut microbiome, as well as
- the minerals phosphorus (energy metabolism) and iron (oxygen transport)
The result is a synergy of enzymes, micronutrients, and probiotics that supports the heart, blood vessels, and metabolism in a holistic way.
- Current research on spike proteins A Japanese laboratory study suggests that nattokinase may also break down SARS-CoV-2 spike proteins. Although this finding is still at an early stage, it highlights the enzyme’s broad potential.
- Pure, organic quality, additive-free Our tablets are made from GMO-free Japanese soybeans only, with no fillers, binders, or flow agents. Manufacturing in Germany ensures consistent quality and high enzyme activity.
- Simple long-term use For optimal results, we recommend continuous intake for at least three months so the full profile, from fibrin regulation to micronutrient balance, can unfold.
How and when should I take the Nattokinase tablets?
The recommended daily amount is two tablets. For optimal absorption, take the tablets on an empty stomach, at least 30 minutes before or 2 hours after a meal, each time with plenty of water.
Morning or evening does not matter. Choose a time you can maintain long term. Because effects observed in studies appear only with continuous use over several weeks, a minimum course of three months is recommended.
Why can individual organic-quality Nattokinase tablets crumble, and how should I use them then?
Our nattokinase tablets are 100% free from additives and are also available in organic quality. Because we intentionally avoid binders, oils, and other stabilizers, the tablets are more brittle than conventional products.
The original soybeans from Japan are naturally low in moisture and do not contain a natural binding agent. Transport may involve strong vibrations beyond our control, so a few tablets in the bottle can break.
To keep the risk as low as possible, we continuously check tablet hardness and fill the product into sturdy plastic bottles with a special closure. Despite these measures, a small share of crumbly tablets cannot be completely avoided. Natural purity takes priority over absolute break resistance.
What matters is this: the efficacy remains unchanged. The enzyme nattokinase and accompanying compounds such as spermidine, vitamin B9, isoflavones, probiotic cultures, phosphorus, and iron are just as active in the powder as in an intact tablet.
If a tablet has broken, simply stir a level teaspoon of the powder the equivalent of one tablet into a glass of water.

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.

Schnelle Lieferung - Presslinge sind teilweise zerbröselt
Schnelle Lieferung, Wirkung kann noch nicht beurteilt werden, da zu kurz eingenommen. Leider sind die Presslinge teilweise zerbröselt.
