What is vitamin K and why do we need it?

Vitamin K is a fat-soluble vitamin that’s involved in hemostasis and bone health. Hemostasis is the process of blood clotting, which prevents and stops bleeding upon injury. A deficiency in vitamin K can cause bruising and problems with bleeding as the blood will take longer to clot.

 

“A vitamin K deficiency is very rare for healthy adults”

 

The body can store vitamin K in the liver for future use, so when you eat more than your body needs, the body will store it and use it on the days that your vitamin K intake is lower.

 

What is the recommended daily intake of vitamin K?

The recommended intake for vitamin K for adults over 18 years is 70 μg/day.

 

A vitamin K deficiency is very rare for healthy adults, as the vitamin can be found in many different food sources. People who malabsorp dietary fats, people with bariatric surgery, people with liver damage or liver disease, or people with a history of prolonged use of antibiotics, may have trouble getting enough vitamin K. These individuals might benefit from vitamin K supplementation.

 

There’s also a risk for newborn babies who may suffer from disordered bleeding, called ‘vitamin K deficiency bleeding’. Most babies get a vitamin K injection after birth or with some given daily droplets of vitamin K across the first few weeks of life.

 

It’s unknown if a high intake of vitamin K can be harmful. If you’re taking a supplement, it’s safe to take a dosage of 1mg or less. People who are taking blood-thinning drugs for medical reasons should be very careful vitamin K supplementation.
