Menadiol

About menadiol

Vitamin K is a fat-soluble vitamin which is essential for blood clotting and in aiding the formation of bones. Lack of vitamin K can lead to unwanted bleeding.

Vitamin K occurs naturally in many foods, especially leafy green vegetables such as cabbage and spinach, and also in avocado, meat, milk, and some cereals.

In jaundice and after some surgery there may be difficulty in absorbing fatty substances which means that not enough vitamin K can be absorbed from the diet. Menadiol is a water-soluble form of vitamin K which prevents vitamin K deficiency in these conditions.
