Your immune system is your body's defense mechanism against injury and illness. It helps destroy harmful influences, such as microbes or toxins that can enter the body and cause disease. The immune system uses several mechanisms such as the inflammatory response and the creation of antibodies to help fight off bacterial pathogens. Vitamin E is necessary to support the function of the immune system.
Immune System Function
Your immune system works by detecting the presence of damage to your cells and tissues. It responds by releasing immune system mediators that increase blood flow to the affected area, attracting white blood cells that destroy bacteria. Some forms of immunity are inherited, such as immunity to distemper, a disease that is often fatal in dogs. Other forms of immunity are acquired by exposure to the pathogens. This exposure can be in the form of a vaccination or through actually contracting the disease.
Vitamin E Function
Vitamin E is an organic compound that your body requires in order to function properly. You cannot synthesize vitamin E internally; you must obtain it through dietary sources. Vitamin E is an antioxidant, meaning it neutralizes harmful free radical molecules in your body that are associated with cell damage. It also bolsters your immune system, allowing you to effectively fight off infections by bacteria or viruses.
Effects of Deficiency
If you're not getting enough vitamin E in your diet, your immune system will weaken and you may be more prone to illness. Fortunately vitamin E deficiency is rare, according to the Office of Dietary Supplements. Vitamin E is readily available in many common foods, but it is a fat-soluble vitamin, meaning it must be consumed with fat in order for your body to properly absorb it. People who have disorders that impair their ability to absorb fat may experience vitamin E deficiency. Symptoms include loss of feeling the limbs, muscle weakness and vision problems.
Vitamin E Sources
Vitamin E is present in a wide variety of foods. Sunflower, safflower and wheat germ oil are high in vitamin E. Peanuts, hazelnuts and sunflower seeds are also good sources. Vitamin E can also be obtained by eating green vegetables such as kale, spinach and broccoli. Many foods that don't naturally contain vitamin E are fortified with this essential nutrient. The Linus Pauling Institute recommends that adults consume 15 mg, or 22.5 IUs, of vitamin E per day.
