The vitamin E is an antioxidant which prevents the neurodegenerative disease of the brain called ataxia. Ataxia is a term for a group of disorders that affect co-ordination, balance and speech. Any part of the body can be affected, but people with ataxia often have difficulties with balance and walking, speaking, swallowing and tasks that require a high degree of control, such as writing and eating. The exact symptoms and their severity vary depending on the type of ataxia a person has. Vitamin E is not good for all kinds of disease. One other disease vitamin E cures is called nonalcoholic steatohepatitis, which is an accumulation of fat in the liver, not due to excess alcohol consumption.
Vitamin E is the collective name for a group of fat-soluble compounds with distinctive antioxidant activities. Antioxidants protect cells from the damaging effects of free radicals, which are molecules that contain an unshared electron. Unshared electrons are highly energetic and react rapidly with oxygen to form reactive oxygen species. Antioxidants protect cells from the damaging effects of reactive oxygen species formed in the body endogenously when it converts food to energy. Health risks from excessive vitamin E can cause hemorrhage and interrupt blood coagulation by inhibiting platelet aggregation.
Vitamin E supplements have the potential to interact with several types of medications. Vitamin E can inhibit platelet aggregation and antagonize vitamin K-dependent clotting factors. Some take vitamin E supplements with other antioxidants, such as vitamin C, selenium, and beta-carotene. These collections of antioxidant ingredients blunt the rise in high-density lipoprotein cholesterol levels, which is the most cardioprotective high-density lipoprotein. There are potential risks of concurrent antioxidant supplementation with conventional therapies treating cancer.
So essentially, we are left with a vitamin which is not good for all kinds of disease, but only where two situations are cured. One is called nonalcoholic steatohepatitis and the other one is a neurodegenerative disease due to an absence of vitamin E called ataxia.
