Vitamin K and Vitamin K Deficiency Bleeding
Vitamin K is a substance that our body needs to form clots and to stop bleeding. We get vitamin K from the food we eat. Some vitamin K is also made by the good bacteria that live in our intestines. Babies are born with very small amounts of vitamin K stored in their bodies, which can lead to serious bleeding problems if not supplemented.
