Learn more about vitamin E
Vitamin E, specifically tocopherols, is a potent antioxidant that protects cells from free radicals. It interacts with selenium and also with vitamin C, two other important antioxidants. Vitamin C can “reactivate” oxidized vitamin E, and vice versa. Selenium and vitamin E strengthen each other’s effects.
Natural vitamin E is actually a complex of eight different forms. Alpha-tocopherol is the most well-known and commonly used among the eight forms due to its higher activity compared to the other tocopherols. Ideally, vitamin E supplements should contain a combination of all these forms to provide the greatest protective effect.
Vitamin E is a fat-soluble vitamin that can be stored in the body, primarily in fat tissue, cell membranes, blood lipids, muscles, heart, lungs, liver, and more. Vitamin E is particularly important for protecting polyunsaturated fatty acids in cell membranes from degradation.
People who avoid fatty foods may experience a deficiency of vitamin E. Similarly, during periods of stress, lack of sleep, illness, or other burdens on the body, it may be beneficial to supplement with vitamin E.
What is vitamin E good for?
Vitamin E interacts with selenium and protects cells from oxidative stress by neutralizing free radicals. Both vitamin E and selenium are important for an efficient immune system. Vitamin E contributes to strong cell membranes, including the membranes of mitochondria. It may help prevent muscle cramps and blood clots. It also supports fertility. Additionally, it lowers bad cholesterol levels and increases good cholesterol levels.
What can a lack of vitamin E mean?
A deficiency of vitamin E can lead to neurological changes, such as unsteady gait, and prolonged deficiency can contribute to heart and cardiovascular diseases. It can also cause joint and muscle pain, among other symptoms.
How do we get vitamin E?
Sources rich in vitamin E include vegetable oils, whole grains, wheat germ, bran, almonds, nuts, and seeds. Colorful fruits and vegetables such as red bell peppers and spinach also contain vitamin E.
Vitamin E has a low toxicity, even in high doses. The upper limit for daily intake of vitamin E from supplements is set at 300 milligrams per day for adults.
Supplements should be taken with a meal for optimal absorption.
