Vitamin K2 benefits bone and heart health. Vitamin K deficiency include: health problems that can prevent your body from absorbing vitamin K, such as gallbladder or biliary disease, bruising, cystic fibrosis, celiac disease, Crohn’s disease, liver disease, taking blood-thinners such as Warfarin, long-term hemodialysis and serious burns.
Vitamin K is used to reduce the risk of bleeding in liver disease, conditions where your body does not absorb enough vitamin K, or if you take antibiotics for a long time.
