Nattokinase 100 mg 20,000 FU/g | 365 Capsules | LUTO Supplements

Nattokinase 100 mg with 2000 FU from natto

Looking for a simple enzyme from fermented soybeans? LUTO Supplements' nattokinase 100 mg provides 2000 FU per capsule, obtained from natto. One jar contains 365 vegetable capsules, enough to last a full year at one per day. Below, we calmly explain exactly what this natto enzyme is, where it comes from, and what to look out for when comparing it.

What nattokinase does in your body

Nattokinase is a serine protease, an enzyme that cuts proteins at specific locations. In the laboratory, it breaks down fibrin, the fibrous protein that gives structure to a blood clot. But what happens when you swallow a capsule? Your body primarily views nattokinase as a protein, which is digested in your stomach and intestines like any other dietary protein. The amount of enzyme that reaches your intestine intact varies from person to person and depends on factors like your stomach acid. We deliberately make no other claims here. For nattokinase, there are no EU-approved health claims; therefore, you will read nothing from us about what else it might do.

What natural nattokinase really is

You often encounter the term "natural nattokinase." Natural here means that the enzyme comes from a food and is not synthetically reproduced in a factory. Nattokinase indeed forms spontaneously 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 soybeans used are also declared non-GMO, so genetically modified soy is excluded.

Why FUs tell more than milligrams

For most supplements, the number of milligrams is sufficient. For an enzyme, this is different. The activity of nattokinase is expressed in FUs (fibrinolytic units), a measure of the enzyme's activity. This product is standardized to 20,000 FU per gram, so 100 mg of powder in a capsule corresponds to 2000 FU. Two jars containing the same number of milligrams can therefore differ greatly in activity. So, those comparing nattokinase capsules look at the FU value, the source, and the purity, not just the weight. This FU activity is measured by a laboratory by placing the enzyme on a thin layer of fibrin and observing the size of the clear area that forms. The larger this area, the higher the FU value. And this is precisely the number that many online stores omit.

A brief composition and the question of soy

The ingredient list is as short as possible: nattokinase, rice flour as a filler, and an HPMC capsule (hydroxypropyl methylcellulose, a plant-based material). No colorants, odors, or flavors, 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, as no animal materials are involved. And with 365 capsules in one jar, you order once and are set for a year.

In short, this is a simple enzyme from natto: 2000 FU per vegetable capsule, standardized to 20,000 FU/g, in a jar that lasts a year. No frills, just nattokinase with a clear FU value and transparent origin from fermented soy.
