Vitamin E also protects against DNA damage: A sufficient intake of vitamin E (alpha-tocopherol) is important as it functions as an antioxidant, protecting cells, tissues, and organs from damaging effects caused by ‘free radicals’, which are responsible for the aging process and can lead to various health conditions such as heart disease, cancer, and inflammatory conditions
People are also exposed to free radicals in the environment from cigarette smoke, air pollution, and ultraviolet light from the sun.
The body also needs vitamin E to boost its immune system so that it can fight off invading bacteria and viruses. It helps to widen blood vessels and keep blood from clotting within them.
Since researchers believe oxidative stress contributes to the development of Alzheimer’s disease, antioxidants like vitamin E could potentially help prevent this condition. The fat-soluble vitamin can readily enter the brain and exert its antioxidative properties.
Vitamin E is found in various foods and oils. Nuts, seeds and vegetable oils contain high amounts of alpha-tocopherol, and significant amounts are also available in green leafy vegetables and fortified cereals.
