Vitamin K

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.

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.

People at increased risk of deficiency may include:

People with impaired absorption: liver problems or celiac disease
People taking medication such as antibiotics and blood thinners.

Vitamin K can be found in a variety of different foods, such as:

Green leafy vegetables, especially:
Spinach
Kale
Broccoli
Grain products
Meat
Dairy products.

However, vitamin K deficiency is rare in Denmark.

Symptoms of vitamin K deficiency can include:

Increased bleeding and bruising
Osteoporosis
Bone pain

Individuals with an increased risk of vitamin K deficiency should consult a doctor if they experience these symptoms.
