We have been making natto since 2015. The brand was founded by engineer Marek Kołodziejski, author of our own convection drying method, who came across fermented soy while looking for a natural complement to his diet. Today every batch is made in our workshop following the same perfected recipe.
What sets our natto apart
High vitamin K2 MK-7 content
Our natto contains approx. 1,970 µg of vitamin K2 MK-7 per 100 g, making it one of the richest natural sources of this vitamin. Vitamin K contributes to the maintenance of normal bones and to normal blood clotting (Regulation (EU) 432/2012).
More about vitamin K2Our own drying process
A three-stage convection drying process developed with LOIiWA in 2017-2018. It preserves active nattokinase and vitamin K2 MK-7, which are lost during standard heat treatment.

Frequently asked questions
How is your natto different from imported natto?
We ferment it ourselves, in our workshop in Zielona Góra, from organic non-GMO soy. Fresh natto goes out straight from production, in thermal packaging, Monday to Thursday.
Where can I buy nattokinase?
Straight from us, in the shop at natto.pl, made in our workshop in Zielona Góra. You will find it in capsules and tablets, and naturally in fresh, dried and freeze-dried natto.
Fresh, dried or capsules, which one to start with?
Fresh natto is food: keep it in the fridge at 2 to 5°C and eat it on its own or with rice. Dried and freeze-dried natto sits in the cupboard at room temperature and you add it to a finished dish. The dried one is made with a method we developed together with the Lubuskie Centre for Innovation and Agrotechnological Implementation (LOIiWA). Capsules and tablets are simply a measured portion, handy at work and when travelling.
How do you pack and ship fresh natto?
We send parcels Monday to Thursday, always in thermal packaging. In Poland the parcel usually reaches you within 24 hours of dispatch, and delivery is free on orders from 300 zł. Abroad, to 25 European Union countries and Switzerland, fresh natto travels by express courier for 70 zł.

Natto contains a high amount of natural vitamin K2 MK-7 and nattokinase, which is described for its fibrinolytic properties. People taking anticoagulant medicines from the group of vitamin K antagonists (warfarin, acenocoumarol) should consult their doctor before eating this product.
