Some vitamins have established roles in supporting the treatment of external bleeding, particularly Vitamin K. Vitamin K is essential for the synthesis of clotting factors II, VII, IX, and X in the liver, which are necessary for normal blood coagulation. Deficiency of Vitamin K can lead to impaired clotting and increased bleeding tendency, both internally and externally. In clinical settings, Vitamin K is administered to patients with bleeding disorders caused by deficiency (e.g., due to malabsorption, liver disease, or use of anticoagulant medications like warfarin). There is robust scientific evidence supporting the use of Vitamin K to reverse bleeding tendencies in these scenarios.

Other vitamins, such as Vitamin C, play a supportive role. Vitamin C is important for collagen synthesis, which is necessary for healthy blood vessel walls. Severe deficiency (scurvy) leads to capillary fragility and spontaneous bleeding, including from the gums and skin. Supplementation with Vitamin C resolves these bleeding symptoms.

While these vitamins are not typically used as first-line acute treatments for external bleeding (where direct pressure and hemostatic agents are more relevant), correcting deficiencies is crucial for prevention and long-term management. Thus, the use of certain vitamins in supporting or treating external bleeding is grounded in scientific understanding of their physiological roles, warranting a moderate evidence rating.
