Vitamin K


Why is it needed? Another representative of the group of fat-soluble vitamins, medically referred to as phylloquinone. The main function of vitamin K is participation in blood clotting processes. Simply put, it prevents the development of all kinds of bleeding and hemorrhage in the mother, fetus, and subsequently the newborn. Considering that pregnancy and (especially!) childbirth require an ideal state of the blood coagulation system in both the woman and her baby, this effect of vitamin K can hardly be overestimated. Sources Natural sources of vitamin K include rose hips, garden strawberries, carrots and tomatoes, as well as white cabbage and cauliflower. Daily Value: The requirement for vitamin K, that is, the amount needed to prevent deficiency under normal conditions, is 1 mcg per kilogram of body weight per day. A person weighing 60 kg needs 60 micrograms of vitamin K per day. A typical diet contains 300 to 500 micrograms of vitamin K per day. Vitamin deficiency is rare, except when diet is severely restricted or when drug interactions interfere with vitamin absorption. Even without food sources, a normally functioning population of gut bacteria can supply enough vitamin K. Breastfed newborns are at risk of becoming vitamin K deficient because human milk contains insufficient amounts of the vitamin and their intestinal flora has not yet grown enough to produce the required amounts. The need for vitamin K in newborns in the first days of life is 10-12 mcg. Modern formulas contain about 4 micrograms of vitamin K per 100 calories, which under normal circumstances will be enough to meet the needs of the body.
