Vitamin E promotes good eye health and vision

Vitamin E:   Antioxidant for eye health and vision

Vitamin E is another essential nutrient due to its effects on both your ocular and overall health.  Coastal Vision Vitamin and Nutrition Corner Vitamin E is a fat-soluble vitamin that helps protect your cells and Vitamin A against oxidation.  Vitamin E is also essential to your circulatory system, assists in the formation of red blood cells, and allows for better use of Vitamin K in the clotting process.

One study has suggested that patients taking Vitamin E supplements had a slower progression of cataracts.   This is believed to be the result of Vitamin E's anti-oxidant protection of the intraocular lens against free radical damage.   Free radicals are circulating chemicals that cause damage to all body tissues and lead to cataracts.

Within the retina, Vitamin E is found in high concentrations within the photoreceptors, which are the cells that absorb light and vision.   And it's the vitamin's antioxidant properties that again come into play by protecting these very important cells from the damaging stress of aging.   Vitamin E was also a component in the supplement treatment of Macular Degeneration in the landmark Age Related Eye Disease Study (AREDS).

In most developed countries, a true deficiency of this vitamin is pretty rare.   In conditions, such as Crohn's, where fat metabolism is disrupted Vitamin E may be markedly deficient.  But most Americans have a diet containing a fair amount of Vitamin E with the moderate need for supplements or dietary additions in order to obtain the vitamin's full benefit.

It should be noted that this vitamin is a fat-soluble vitamin, which means that excess intake could have harmful effects.    Excess use may increase risk for hemorrhagic events (stroke) and may demonstrate muscle weakness, headaches, fatigue, and decreased thyroid function.   If you are taking blood thinning agents, Vitamin E should be discussed with your primary care physician before taking larger amounts.
