Nattokinase 100mg (2000 FU) | 365 Capsules | Vit4ever

Nattokinase by Vit4ever

Nattokinase is an enzyme that naturally occurs when soybeans are fermented to make natto, a traditional Japanese dish. Vit4ever captures this enzyme in a capsule: 100mg of nattokinase per capsule, with a fixed activity of 2000 FU. The bottle is available in two sizes, 180 or 365 capsules, so you can choose how much stock you want to keep at home. Convenient for those who do not want to eat natto every day but are still curious about this enzyme.

How nattokinase is produced and what FU means

Natto has been eaten in Japan for over a thousand years and is made by fermenting cooked soybeans with the bacterium Bacillus subtilis natto. During this fermentation process, the bacterium breaks down proteins, producing nattokinase, an enzyme from the serine protease group. For this supplement, Vit4ever uses non-genetically modified soybeans, from which the enzyme is extracted and concentrated into a capsule filling. This means you do not have to eat a plate of natto yourself, which, by the way, has a distinctive taste and a sticky texture. With nattokinase, you often see two numbers on the label: the weight in milligrams and the activity in FU, which stands for Fibrinolytic Units. FU describes how active the enzyme is, not how many grams are in the capsule, so two products with the same weight can still have a different FU value. At Vit4ever, each capsule provides a fixed 2000 FU, or 20,000 FU per gram, so you know exactly what you are taking in every day without the activity varying from batch to batch.

Why there is no vitamin K

Some natto supplements also contain vitamin K2, because natto is naturally a source of this vitamin. Vit4ever deliberately chooses not to add it to these capsules. This leaves you with a pure enzyme product. Those who would prefer a combined product can look for a vitamin K supplement separately. By keeping the two separate, you decide exactly what you are taking in and in what ratio, instead of having a manufacturer make that choice for you.

Capsule composition

In addition to the nattokinase itself, each capsule contains only rice extract as a filler and a hydroxypropyl methylcellulose capsule shell, a plant-based substance that gives the capsule its shape. There are no colorings, preservatives, or magnesium stearate. Vit4ever has every produced batch independently tested for heavy metals and microbiological contamination before it is released for sale. People who occasionally research exactly what is in a supplement regularly ask about this: for this product, the answer is short, three ingredients and a test report per batch.

Two bottle sizes, the same capsule

You can choose between a bottle of 180 or 365 capsules. The only difference is the quantity, not the composition: every capsule from both bottles contains exactly the same 100mg of nattokinase with 2000 FU. With a dosage of 1 capsule per day, the smaller bottle means six months of use and the larger one a full year, so you can first try the small bottle before switching to the year's supply. This particularly appeals to people who research enzymes from fermented food and would rather not eat natto as a dish, but do want to try the enzyme in standardized form. Because the fermentation takes place in a controlled process and every batch is tested separately, you know exactly what you are taking in, unlike making natto yourself at home where the fermentation time is difficult to reproduce exactly.

Nattokinase thus remains an enzyme with a clear origin: fermented soy, standardized to FU activity, and nothing else added. Whether you choose the bottle of 180 or 365 capsules, the composition per capsule remains exactly the same. This way, you know exactly what you are taking in with every dose.

The distinction between milligrams and FU activity is relevant, because manufacturers do not always use those terms in the same way. At Vit4ever, the FU value is fixed at 2000 per capsule, which makes comparing it with other products easier than when only the weight is stated.
