Vitamin K



Vitamin K is a fat-soluble vitamin that plays an important role in blood clotting and bone metabolism. It is a necessary nutrient to maintain the health and function of our body.



Vitamin K plays a vital role in blood clotting by helping to activate various proteins in the blood that are responsible for stopping bleeding. It also helps maintain the health of our bones and teeth by supporting bone metabolism. In addition, it may also play a role in preventing heart disease.

How much Vitamin K should you eat in a day?

NNR (the Nordic Nutrition Recommendations) has no evidence for what amount is sufficient for men/women.

Netdoctor describes that 1 microgram (mcg) is the recommendation for both men and women, which they probably have from the recommendation from NNR 2004.

A fun fact about vitamin K is that it can also play a role in memory and cognition. Research has shown that vitamin K may be important in protecting the brain from age-related breakdown and improving cognitive functions such as memory and attention. This is likely due to vitamin K's role in supporting healthy bone and blood vessel function, as these can also affect brain health and cognitive function.
