Vitamin K is an important vitamin for many different bodily functions, but its most crucial role is in helping the blood clot and preventing excessive bleeding. Unlike many other vitamins, vitamin K is not typically taken as a dietary supplement.
There are actually two types of Vitamin K – Vitamin K1 and Vitamin K2. Vitamin K1 can be found in leafy greens and some other vegetables, while Vitamin K2 is usually found in meats, cheeses, and eggs, and is also synthesized by bacteria.
Vitamin K1 is the most commonly found form of vitamin K in supplements available in the United States. Recently, some people have turned to vitamin K2 to treat osteoporosis and bone loss brought on by steroids, but the research is inconclusive at this point. There is not enough data to support using vitamin K2 to treat osteoporosis.

Why do people take vitamin K?
Vitamin K is essential for blood clotting and a lack of it can lead to uncontrolled bleeding. Deficiencies in vitamin K are rare in adults, but they are very common in newborn infants. A single injection of vitamin K is standard for newborns. Vitamin K is also used to counteract an overdose of the blood thinner Coumadin.
While vitamin K deficiencies are uncommon, you may be at higher risk if you:
- Have a disease that affects absorption in the digestive tract, such as Crohn’s disease or active celiac disease
- Take drugs that interfere with vitamin K absorption
- Are severely malnourished
- Drink alcohol heavily
In these cases, a healthcare provider might suggest vitamin K supplements.
Symptoms of Vitamin K Deficiency
The primary symptom of vitamin K deficiency is bleeding. This can manifest in many ways, such as skin blemishes, nosebleeds, gastrointestinal bleeding, and more. sometimes, if the stomach is affected, one may vomit up blood. Blood may also be present in stool or urine.
In newborns, life-threatening bleeding may occur within or around the brain.
Having a liver disorder increases the risk of bleeding because clotting factors are made in the liver.
A deficiency of vitamin K may also cause weak bones.
Can you get vitamin K naturally rich from foods?
Good natural food sources of vitamin K include:
- Vegetables like spinach, asparagus, and broccoli are rich foods of vitamin k
- Legumes like soybeans
You can also meet your daily requirement with foods that have lesser amounts of vitamin K:
- Meat like liver
Vitamin K safety and side effects
Vitamin K is fairly safe. However, it can interact with certain medications, including blood-thinning drugs. If you have an allergy to soy, be aware that most MK-7 forms of vitamin K are derived from soy — although one brand is derived from chickpeas.
The Bottom Line
The function of vitamin k in our body is to produce prothrombin, a protein, and clotting factor that is important in blood clotting and bone metabolism.
Phylloquinone, also known as vitamin K1, is found in plants. When people eat it, bacteria in the large intestine convert it to its storage form, vitamin K2. It is absorbed in the small intestine and stored in fatty tissue and the liver.
Vitamin K supplements should only be used if your healthcare provider tells you to. People using Coumadin for heart problems, clotting disorders, or other conditions may need to watch their diets closely to control the amount of vitamin K they take in. They should not use vitamin K supplements unless advised to do so by their health care provider.
