What is vitamin K?
“Vitamin K,” the generic name for a family of compounds with a common chemical structure of 2-methyl-1,4-naphthoquinone, is a fat-soluble vitamin that is naturally present in some foods and is available as a dietary supplement [ 1 ]. These compounds include phylloquinone (vitamin K1) and a series of menaquinones (vitamin K2) [ 2 ]. Menaquinones have unsaturated isoprenyl side chains and are designated as MK-4 through MK-13, based on the length of their side chain [ 1, 2 ]. MK-4, MK-7, and MK-9 are the most well-studied menaquinones.
How much Vitamin K is excreted?
Vitamin K is rapidly metabolized and excreted. Based on phylloquinone measurements, the body retains only about 30% to 40% of an oral physiological dose, while about 20% is excreted in the urine and 40% to 50% in the feces via bile [ 2, 11 ].

What is the purpose of vitamin K?
Vitamin K refers to a group of structurally similar fat- soluble molecules that are primarily involved in the synthetic pathways of a number of clotting factors. Vitamin K is also involved in bone metabolism.
How do you get vitamin K?
Adults get vitamin K from food — mainly leafy green vegetables — and from bacterial synthesis in the gut. Babies have very little vitamin K in their bodies at birth because only small amounts of the vitamin pass through the placenta. Also, the bacteria that produce the vitamin in the newborn’s intestines are not yet present. Breast milk contains only low levels of vitamin K, and it may take weeks to months for the infant’s ‘sterile’ gut to become established and functional. Infants are therefore predisposed to having low vitamin K levels, resulting in low levels of vitamin K-dependent clotting factors, and an increased risk for bleeding, termed vitamin K deficiency bleeding.

Infants who do not get the vitamin K shot at birth are at 81 times greater risk for developing VKDB than infants who do get the shot. VKDB is effectively prevented by the vitamin K shot — incidence of late VKDB, the most concerning type, falls to less than 1/100,000 infants when vitamin K is given at birth.
Causes
- A vitamin K deficiency is usually found in infants since the placenta is not a very good carrier of this nutrient, thereby resulting in the development of conditions like vitamin K deficiency bleeding (VKDB). A vitamin K deficiency can easily turn into osteoporosis or a serious heart condition.
Chemistry
- Vitamin K consists of a group containing 2-methyl-naphthoquinone derivatives. The three notable forms of this vitamin are K1 (phytonadione, phylloquinone, phytonadione), K2 (menaquinones), which is formed by natural bacteria present in the intestines, and K3 (menadione).
Prevention
- Vitamin K plays a key role in preventing osteoporosis and loss of bone mineral density, according to Dr. Debra Pearson of the University of Wisconsin-Green Bay. The intake of leafy vegetables, collard greens, broccoli, spinach, brussels sprouts, and lettuce, all of which are rich in this vitamin, helps prevent the signs and symptoms. Even cow milk is a good and rich source of this vitamin …
Function
- Vitamin K helps in the regulation of blood clotting by transporting calcium around the body. It plays a key role in the amalgamation of prothrombin that happens at the time of injury due to the tears in blood vessels. Protein Z helps in enhancing the action done by thrombin so as to promote an association with phospholipids that are present in cell membranes. It further helps in treatin…
Side effects
- Vitamin K deficiency can lead to a woman experiencing excess menstrual bleeding. Therefore intake of adequate amounts of vitamin k is important and will reduce the blood flow.
Results
- Pregnant women suffering from vomiting and nausea are often deficient in vitamin K. This vitamin intake will show good results by providing relief in less than seventy-two hours and preventing mild forms of these symptoms in the future.
Research
- Vitamin K plays an important role in regulating blood sugar levels and reducing the risk of developing diabetes, as per the American Diabetes Associations journal Diabetes Care. t is believed that vitamin k supplementation is more effective in preventing diabetes among older men when compared to women.
