Who this product is for
Food supplement for adults:
- those looking to supplement their diet with vitamin K (K2 MK-7) from a natural source, namely fermented organic natto
- those wishing to supplement their diet with vitamin D3 (a daily dose of 2000 IU corresponds to the recommended supplementation in Poland during the winter period)
- those who prefer a convenient tablet form over fresh natto (taste, texture)
- people following a plant-based diet, as D3 from marine algae is a vegan form
Contraindications and warnings
The product contains soy (allergen). Do not use in case of allergy to soy or soy products.
High content of natural vitamin K. People taking oral anticoagulant medication from the vitamin K antagonist group (warfarin, acenocoumarol, phenprocoumon) must consult the doctor supervising their treatment before including this product in their diet.
Vitamin D3 at a dose of 50 µg (2000 IU) is consistent with the recommended daily supplementation for adults in Poland during the autumn-winter period. People taking other vitamin D supplements or medications containing vitamin D should ensure they do not exceed the upper tolerable intake level (4000 IU per day).
Do not exceed the recommended daily serving. A food supplement must not be used as a substitute for a varied diet. A balanced diet and a healthy lifestyle are the basis for the normal functioning of the body. Intended for a healthy adult population up to the age of 75. After the age of 75, medical consultation is recommended.
Keep out of reach of young children.
How to use
Recommended daily serving: 2 tablets, during or immediately after a meal. Take with water.
Absorption of vitamins K and D. Both vitamins are fat-soluble. Taking them with a source of fat (olive oil, avocado, seeds) supports their absorption.
Package: 120 tablets = 60 days of use.
Best before: 26 months (the date on the packaging also serves as the batch number).
Storage: in a cool place, from 7 to 12°C, for example in the fridge.
Tablets are produced without excipients, which may make them more fragile during transport. We take care to minimise this risk.
Scientific context
Vitamin K (in K2 MK-7 form) and vitamin D are the subject of numerous scientific publications. The scientific bibliography on vitamin K2 MK-7 and its bioavailability is available on the Natto and vitamin K2 MK-7 page.
The cited scientific literature serves to illustrate the research context and does not constitute authorised health claims. For authorised EFSA claims for vitamins K and D, see the “Ingredients” section above.
Quality and origin
A fully organic product. We ferment certified organic soy (non-GMO) the traditional way, with Bacillus subtilis Natto bacteria, in our facility in Zielona Góra. We are the only producer of organic natto in Poland.
We then dry the fresh natto convectively at low temperature, using our own technology. We developed it from 2017 to 2018 with the Lubuskie Centre for Innovation and Agrotechnological Implementation (LOIiWA), to preserve the properties characteristic of fresh natto.
We source vitamin D3 from a marine algae extract (lichen-derived cholecalciferol) rather than the standard lanolin D3. This is a vegan form.
