Vitamin K is scientifically validated for use in treating and preventing internal bleeding, particularly when the bleeding is due to vitamin K deficiency or the use of vitamin K antagonist anticoagulants (such as warfarin). Vitamin K is essential for the synthesis of clotting factors II, VII, IX, and X in the liver. Without adequate vitamin K, these clotting factors are produced in an inactive form, leading to impaired blood coagulation and an increased risk of bleeding, including internal hemorrhage.

The use of vitamin K for this purpose is well established in clinical medicine. It is routinely administered as an antidote to reverse the effects of warfarin overdose or toxicity, which can result in life-threatening internal bleeding. Additionally, vitamin K is administered to newborns to prevent hemorrhagic disease of the newborn, a potentially fatal bleeding disorder.

Numerous clinical studies and guidelines from major health authorities, including the World Health Organization, the American College of Chest Physicians, and the American Society of Hematology, support the use of vitamin K in the management of bleeding associated with vitamin K deficiency or anticoagulant therapy. Its efficacy in rapidly restoring normal clotting factor activity and controlling bleeding is well documented.

However, vitamin K is not effective for all causes of internal bleeding; its use is specifically indicated when bleeding is due to a deficiency of vitamin K-dependent clotting factors. In summary, the use of vitamin K for internal bleeding is based on robust scientific evidence and clinical experience.
