The body needs vitamin E to function, making it an essential vitamin. It is fat-soluble, meaning that it requires fat from the diet to be properly absorbed. Vitamin E is mainly stored in the liver before being released into the blood stream for use.
Deficiency is uncommon and typically the result of an underlying condition.
Vitamin E occurs in eight chemical forms. With a blood test, a doctor can learn how much of one form a person has. Using this information, they can determine whether a person's overall level of vitamin E.
Low levels of vitamin E can lead to:
Muscle weakness: Vitamin E is essential to the central nervous system. It is among the body's main antioxidants, and a deficiency results in oxidative stress, which can lead to muscle weakness.
Coordination and walking difficulties: A deficiency can cause certain neurons, called the Purkinje neurons, to break down harming their ability to transmit signals.
Numbness and tingling: Damage to nerve fibers can prevent the nerves from transmitting signals correctly, resulting in sensations which are called peripheral neuropathy.
Vision deterioration: A vitamin E deficiency can weaken light receptors in the retina and other cells in the eye. This can lead to loss of vision over time.
Immune system problems: Some research suggests that a lack of vitamin E can inhibit the immune cells. Older adults may be particularly at risk.
Muscle weakness and difficulties with coordination are neurological symptoms that indicate damage to the central and peripheral nervous systems.
The peripheral system is the network of nerves located beyond the brain and spinal cord. These neurons pass messages throughout the body.
Causes of vitamin E deficiency:
Vitamin E deficiency often runs in families.
Vitamin E deficiency can also result from diseases that severely reduce the absorption of fat. This is because the body requires fat to absorb vitamin E correctly.
Deficiency is also common in newborns and babies born prematurely who have lower birth weights and less fat.
Premature infants are at particular risk because an immature digestive tract can interfere with fat and vitamin E absorption.
Vitamin E in the diet
It is highly unlikely that a person has low levels of vitamin E unless they have an underlying chronic disease, a genetic condition, or a diet extremely low in fat. For others, supplementation is usually not necessary.
Vitamin E is plentiful in a wide variety of foods. The body cannot produce it, so it must be obtained from the diet or a supplement. Sona offer a range of vitamin E products. See the Sona website for more details.
Foods that contain vitamin E include:
· vegetable oils, such as wheat-germ oil, peanut oil, and olive oil
· nuts, seeds
· whole grains
· most vegetables, including spinach, Swiss chard, red peppers, and avocados
