Vitamin K is a fat-soluble vitamin which exists naturally in two forms:
- Vitamin K1 (Phylloquinone) found in plants and vegetables such as: spinach, broccoli, cabbage, lettuce and collard greens and other foods such as milk, potatoes, oats, tomatoes and in most fruits.
- Vitamin K2 (Menaquinone - MK) which is synthesised by bacteria within the intestinal tract
Vitamin K accumulates in the liver, spleen and lungs but the body does not store significant amounts for long periods of time.
Vitamin K plays an important role in the maintenance of normal bone health and normal blood clotting.
