Detailed explanation-1: -There are biologically plausible mechanisms whereby vitamin E may cause bleeding. Tocopheryl quinone is an oxidised form of alpha-tocopherol with anticoagulant activity. It can interfere with vitamin K metabolism, theoretically causing bleeding. Vitamin E may also inhibit platelet aggregation.
Detailed explanation-2: -Yet in some people, vitamin E causes bleeding. Scientists have known for more than 50 years that excess vitamin E promotes bleeding by interfering with vitamin K, which is essential in blood clotting.
Detailed explanation-3: -Vitamin E deficiency can cause a form of anemia in which red blood cells rupture (hemolytic anemia Anemia due to excessive red blood cell destruction ). Premature infants who have a vitamin E deficiency are at risk of this serious disorder.
Detailed explanation-4: -The vitamin E deficiency causes problems such as poor transmission of nerve impulses, muscle weakness, sterility and degeneration of the retina that can cause blindness.
