Vitamin K (made up of the variants K1 and K2) is important for effective blood clotting. Vitamin K1 can be found in green leafy vegetables and vegetable oils, as well as in fruit, dairy and bread in smaller amounts.
Vitamin K2 can be produced in the bowel from vitamin K1 and is also present in small quantities in liver, cheese and egg yolks.
A food source that is rich in vitamin K2 is natto, a Japanese soya product.
Vitamin K and your health
There are health effects associated with consuming sufficient vitamin K.

Vitamin K is involved in the regulation of bone mineralisation. For this reason, vitamin K (particularly vitamin K2) appears to play a role in preventing osteoporosis.
