Menaquinone 7

Menaquinone 7 (MK-7) is a form of vitamin K2, a fat-soluble nutrient. It is naturally produced by bacterial fermentation and is found in some fermented foods like natto (fermented soybeans) and certain cheeses. It can also be produced commercially through specific bacterial fermentation processes.

MK-7 is primarily used as a dietary supplement to support vitamin K intake. It is sometimes included in meal replacement products and smoothies, likely to enhance their nutritional profile. Its function in these products is as a nutrient.

Menaquinone 7 is not an authorised food additive in the UK. It is recognised as a source of vitamin K. Vitamin K is essential for normal blood clotting and contributes to the maintenance of normal bones. The European Food Safety Authority (EFSA) has evaluated vitamin K, and authorised health claims related to its functions are permitted on food products under specific conditions. Evidence regarding specific benefits of MK-7, such as cardiovascular health, is an area of ongoing research, with some studies suggesting potential benefits while others require further investigation.
