Vitamin K (Phytonadione) Roles

Vitamin K (phytonadione) is fat-soluble vitamin, so deficiency rarely occurs. The bacteria located in the small intestine produces it, and yoghurt, which encourages "good" bacteria growth in the small intestine, can be a contributing factor towards preventing vitamin K (phytonadione) deficiency. The primary function is for the body to form prothrombin, which is required for blood clotting. It also promotes healthy bones, prevents hemorrhagic disease of the newborn, and promotes normal growth.

Vitamin K (Phytonadione) Foods

Most sources of vitamin K (phytonadione) are found in plant foods such as alfalfa, broccoli, leafy green vegetables, Brussels sprouts, green tea, wholegrains, and tomatoes. Animal sources include yogurt, liver, cheddar cheese, and egg yolks.

Vitamin K (Phytonadione) Deficiency

Vitamin K (phytonadione) can result in hemorrhaging throughout the body including nosebleeds, postoperative bleeding, blood in the urine or eye, intestinal bleeding due to blood clotting problems. It can also cause miscarriages, colon problems, and osteoporosis.
