Are you looking for a single enzyme from fermented soybeans? Nattokinase 100 mg from LUTO Supplements delivers 2000 FU per capsule, extracted from natto. One bottle contains 365 plant-based capsules, enough for a whole year at one per day. Below we explain what this natto enzyme is exactly, where it comes from and what to look out for when comparing it.
Nattokinase is a serine protease, an enzyme that cuts proteins at specific locations. But what happens when you swallow a capsule? Your body primarily sees nattokinase as a protein, which is digested in your stomach and intestines just like other food proteins. How much of the enzyme reaches your intestine intact varies from person to person and depends on factors such as your stomach acid. Furthermore, we deliberately make no claims about it here. This is because there are no EU-approved health claims for nattokinase, so you will not read anything about what it does afterwards on our website.
You often see the term 'natural nattokinase'. Natural here means that the enzyme comes from a food source and is not synthetically recreated in a factory. Nattokinase is formed naturally when soybeans ferment with the bacterium Bacillus subtilis var. natto, exactly as in the traditional Japanese dish natto. After fermentation, the enzyme is extracted from the beans and purified into a powder. No chemical synthesis is involved. The soy used for this is also declared GMO-free, so genetically modified soy is excluded.
With most supplements, the number of milligrams tells you enough. With an enzyme, that is different. The activity of nattokinase is expressed in FU (Fibrinolytic Units), a measure of how active the enzyme is. This product is standardized to 20,000 FU per gram, which means that 100 mg of powder in one capsule equals 2000 FU. Two bottles with the same number of milligrams can therefore differ significantly in activity. When comparing nattokinase capsules, you should therefore look at the FU value, the source and the purity, and not just the weight. And that just happens to be the figure that many webshops omit.
The ingredient list is as short as it can be: nattokinase, rice flour as a filler and a capsule made of HPMC (hydroxypropyl methylcellulose, a plant-based material). No colorings, flavorings or aromas and no magnesium stearate. A question that often comes up is about soy. The enzyme is extracted from soy, so soy is listed as an allergen on the label. If you are allergic to soy, do not use this product without first consulting your doctor. For those who eat plant-based, the capsule is perfectly suitable, because no animal material is involved. And with 365 capsules in a bottle, you order once and you are set for a year.
In short, this is a single natto enzyme: 2000 FU per plant-based capsule, standardized to 20,000 FU/g, in a bottle that lasts a year. No bells and whistles, just nattokinase with a clear FU value and a transparent origin from fermented soy.
The enzyme is derived from fermented soy with Bacillus subtilis var. natto and is standardized to 20,000 FU per gram. Declared GMO-free, with batch controls for purity and a transparent label value.
Each capsule provides 100 mg of nattokinase, equivalent to 2000 FU of enzyme activity.
One jar contains 365 capsules, enough for a full year at one per day. So you order once instead of every month, while most brands sell jars of 30 to 90 capsules.
The HPMC capsule is vegetable-based and suitable for vegetarians and vegans. Short ingredient list without colourings, fragrances or flavourings and without magnesium stearate.

No. Natto is a traditional food and not a medicine, nor is this supplement. However, nattokinase can affect blood clotting. Therefore, we advise against its use in combination with blood thinners or antiplatelet drugs, in cases of known clotting disorders, and around a planned operation, unless your doctor explicitly agrees. If in doubt, consult your doctor or pharmacist first.
The main concern revolves around blood clotting: do not use nattokinase with blood thinners and stop well before surgery, in consultation with your doctor. Additionally, the product contains soy, so it is not suitable for those with a soy allergy. It is also not intended for children, pregnant women, or breastfeeding women. Some people experience mild stomach upset with enzyme supplements. And because it is a protein, absorption can vary per person.
FU stands for Fibrinolytic Units and is a measure of the enzyme's activity, not its weight. This product is standardized at 20,000 FU per gram, meaning 100 mg of powder per capsule equates to 2000 FU. Therefore, when comparing nattokinase products, you should compare them based on FU and not just milligrams, as two jars with the same milligram content can still differ in activity.
Nattokinase is extracted from soy, so soy is listed as an allergen on the label. If you have a soy allergy, do not use this product without consulting your doctor. The soy used has been declared GMO-free, so genetically modified soy is excluded. The capsule itself is plant-based (HPMC) and contains no animal ingredients, making the product suitable for a plant-based diet.
Nattokinase is a protein enzyme and can therefore be sensitive to stomach acid and digestive enzymes. There are products with an enteric coating to protect enzymes until they reach the intestines; these capsules are not specified as such. Taking it with a meal and a glass of water is a practical way to use it. The actual absorption can vary per person and depends on factors such as stomach acid production and digestion.
Nattokinase and serrapeptase are both proteolytic enzymes, but they differ in origin and unit of measurement. Nattokinase comes from fermentation with Bacillus subtilis var. natto and its activity is expressed in FU (Fibrinolytic Units). Serrapeptase is a bacterial enzyme originally associated with the silkworm and is usually measured in SU or SPU. Due to these differences, they are not interchangeable one-to-one; the choice depends on your goal and personal preference.
