Menaquinone

Menaquinone is a group of fat-soluble compounds, also known as vitamin K2. It is naturally produced by bacteria in the gut and is found in certain fermented foods like natto (fermented soybeans) and some cheeses. It can also be synthesised for use in supplements and fortified foods.

Menaquinone is primarily added to foods as a source of vitamin K2, which plays a role in bone health and blood clotting. It is commonly found in meal replacements, nutritionally complete foods, and dietary supplements, where it contributes to the overall nutritional profile of the product.

Menaquinone is not regulated as a food additive in the UK and is considered a nutrient. Vitamin K, including menaquinone, is essential for normal blood clotting and maintaining healthy bones. The European Food Safety Authority (EFSA) has evaluated vitamin K and concluded that it contributes to normal blood coagulation and the maintenance of normal bones. Evidence regarding specific health benefits beyond these established roles is still under investigation.
