Our vitamin K2 or menaquinone is a fat-soluble vitamin (soluble in the adipose tissues). It takes its name from the German Koagulation, which relates to its role in blood clotting.
Dose: 75 µg per day
Fermented soybean paste (miso), liver, milk, cheese, yoghurt and fish oils.
Vitamin K exists in three forms:
- Vitamine K1 of plant origin is present in food
- Vitamine K2 produced by the bacteria in the intestines and in food
- Vitamine K3 obtained by chemical synthesis.
- to keep bones healthy
- with blood clotting
An insufficient vitamin K intake leads to bruising, nosebleeds, dark black stools, heavy periods and osteoporosis. Some studies report that the lower the vitamin K intake, the higher the risk of fractures. It is therefore advisable to ensure an adequate vitamin K intake, to prevent the risk of osteoporosis.
In Europe, the EFSA committee (EFSA, 2006; 2010) stipulated that the intake in adults and children should represent the equivalent of 1 μg/kg of body weight, even if the origin of the intake is mainly an endogenous bacterial source (intestinal microbiota).
