Vitamin K deficiency is a condition in which the body fails to produce enough of this essential nutrient. People can become deficient for various reasons, including malnutrition, certain prescription medications and conditions involving fat malabsorption.
Doctors typically diagnose vitamin K deficiency with a blood test called either the prothrombin time (PT) or international normalized ratio (INR). Both tests measure how long it takes for blood to clot.

Vitamin K Deficiency during Pregnancy
Vitamin K is essential during pregnancy, helping the blood clot and creating proteins in the liver. Additionally, it aids fetal development as well as maintaining healthy calcium levels throughout the body.
Vitamin K is a fat-soluble vitamin found in foods like dairy products, green leafy vegetables and meats. Additionally, some supplements also contain it.
Prenatal vitamin K is essential for pregnancy as it aids the baby’s bones and muscles in growing and developing properly, especially after delivery. Furthermore, vitamin K helps the blood clot more tightly so that babies are less likely to bleed after delivery.
Pregnant women should take a daily multivitamin with plenty of vitamin K, as vitamin K deficiency in the mother is extremely rare but can have serious consequences for the unborn child.
Vitamin K is primarily obtained from green leafy vegetables and milk (especially skimmed). There are two major forms of Vitamin K: phylloquinone and menaquinones. Phylloquinone is the most prevalent form found in foods; it’s produced primarily by Bacillus coagulans bacteria found in fermented items like dairy products.
Vitamin K can also be found in certain foods like nuts, fish and meat; however, these sources are not as easily absorbed or utilized by the body as other dietary sources.
Vitamin K deficiency can be caused by a number of different factors. It could occur if the fetus is growing slowly than expected, or if the mother’s diet lacks essential vitamins and minerals. Furthermore, certain drugs that affect vitamin K absorption could also play a role.
Vitamin K deficiency during pregnancy poses the major risk of decreased blood clotting protein prothrombin, which could result in bleeding both for the mother and fetus. This bleeding can occur in various places throughout the body such as the brain or intestines.
Women with intrahepatic cholestasis are particularly at risk for this type of bleeding, as the bile and pancreatic enzymes that break down vitamin K in the intestines are weakened.
Vitamin K Deficiency: Breastfeeding
Newborns who don’t receive enough vitamin K while in the womb or during breastfeeding are at risk for vitamin k deficiency bleeding (VKDB), a serious illness. If your baby has this issue, give them an immediate shot of vitamin K to combat the damage that could otherwise happen.
Breast milk often contains high levels of Vitamin K, as the nutrient is fat soluble and stored in small globules of milk fat.
It also makes it easier for babies to absorb vitamin A, helping prevent blood clots in the brain.
Studies have demonstrated that pregnant women who take a supplement with vitamin K during the last few weeks of their pregnancy can increase their baby’s intake of this nutrient, potentially decreasing the risk of VKDB in the offspring. This occurs because taking these supplements helps them make more milk and distribute it more effectively to the baby.
In another study, researchers observed that breastfeeding mothers with premature infants who took a daily supplement of Vitamin K experienced increased levels of Vitamin K in their breast milk.
Mothers can protect their babies from vitamin k deficiency by delivering vaginally and breastfeeding, which will encourage the growth of beneficial bacteria in their gut. When this occurs, those bacteria produce more of their own Vitamin K.
However, breast-feeding and vaginal delivery have been known to increase the concentration of Vitamin K in mother’s milk. One study found that these practices led to an increase in Vitamin K concentration of up to 2%.
Babies who are exclusively breast-fed do not appear to be at risk for vitamin k deficiency. This may be because the formulas they consume have high levels of Vitamin K1–55 micrograms per liter.
The National Institutes of Health recommend that newborns who don’t get enough Vitamin K at birth receive a shot of this essential nutrient. It is a safe and reliable way to prevent bleeding in your infant.
Antibiotics
Antibiotics are drugs used to combat infections caused by bacteria. They work by either killing the bacterium (bactericidal) or stopping it from growing or reproducing (bacteriostatic). Some antibiotics have even been known to eliminate viruses and fungi.
These medicines are often prescribed by doctors and available at pharmacies or health food shops. They must be taken regularly, for the right length of time, and in correct doses; when used properly they can be highly effective; however if overused it could lead to bacteria becoming resistant or “superbugs,” or resistant to treatments that once killed them.
Bacteria can become resistant to antibiotics by adapting or changing their genetic material in order to become less sensitive to them. This can occur due to different kinds of antibiotics, how they’re produced or excessive usage by people.
Vitamin K is a fat-soluble vitamin essential for bone and heart health, blood clotting, and brain function. It’s found in various foods like green leafy vegetables, milk or other dairy products, oily fish, nuts/seeds and grains.
Vitamin K deficiency is uncommon among healthy adults, but it may occur if you take certain medications or don’t absorb enough of the vitamin through your stomach. Your doctor can diagnose a vitamin K deficiency by performing a blood test called the prothrombin time or PT test to check how long it takes for your blood to clot normally.
Vitamin K deficiency can manifest itself in various ways, including excessive bleeding from the nose or throat, cuts or wounds and sometimes from the intestines. You may also observe it in urine or stools which appear tarry. In newborns with this deficiency, life-threatening forms of bleeding around or inside the brain can take place.
Vitamin K deficiency can be caused by several factors, including liver disease or malnutrition. Your doctor may advise you to avoid foods high in this vital nutrient such as cruciferous vegetables or liver.
If you have a vitamin K deficiency, your doctor can provide vitamin K supplements or medicine to help your body absorb it from food. They may also prescribe antibiotics which could prevent or reduce some of the symptoms associated with such an imbalance – including bleeding.
Diet
The human diet can vary considerably based on culture and individual preferences. It may include food items like grains, vegetables, fruits, meats, poultry, seafood, dairy products or other meals; in addition it may be tailored towards specific health or weight-management objectives.
Dietary sources of essential nutrients like vitamins, minerals and other substances for proper body functioning should include vitamin K. This essential nutrient plays many roles in human health – from aiding blood clotting (prothrombin) to building strong bones (osteocalcin).
Most adults get enough vitamin K from their food sources, but some require dietary supplements to meet their requirements. The recommended dietary allowance (RDA) for vitamin K is 120 micrograms per day for men and 90 micrograms per day for women; most of this required amount can be found in vegetables and other leafy greens.
Vitamin K is a fat-soluble vitamin that your body breaks down and excretes through urine. Because your body stores very small amounts of this vitamin, you must ensure you consume enough daily to prevent dangerously high concentrations.
Vitamin K1 exists in several forms, such as phylloquinone (vitamin K1) and menaquinones MK-4 through MK-13. These metabolites are important for carboxylation of proteins essential for healthy blood and bone.
Vitamin K deficiencies can cause excessive bleeding and other serious health problems, so it’s essential to eat a balanced diet with plenty of fruits, vegetables, and whole grains – especially for those with high blood pressure or diabetes.
Studies have linked low vitamin K intakes with age-related bone loss, or osteoporosis. Children and adolescents who consume more vitamin K-rich foods such as cheese, milk, yoghurt, and broccoli have been found to be at lower risk for developing osteoporosis.
Research suggests low vitamin K intakes may contribute to coronary heart disease risk, though this has yet to be definitively established in clinical trials. One randomized double-blind study examined the effects of vitamin K supplementation on coronary artery calcification among healthy men and women aged 60-80 years; results revealed no significant difference in coronary artery calcification between treatment and control groups.
