Vitamin E is a powerful antioxidant and necessary nutrient. It can help stave off cell damage from all sorts of environmental and internal toxins.

Vitamin E is a fat-soluble nutrient that protects cell membranes from oxidation and destruction. Vitamin E acts as an antioxidant in the body where it helps protect cells from damage caused by free radicals, which are compounds formed when the body converts foods we eat into energy. Free radicals are also present in the environment from cigarette smoke, air pollution, and ultraviolet light from the sun. Vitamin E can be found in many foods as well as nutritional supplements.

  • Boosts the immune system 
  • Acts as a natural blood thinner by helping widen blood vessels, which prevents blood from clotting within them
  • Helps with formation of red blood cells

What Is the Recommended Daily Amount of Vitamin E?

The doses in most vitamin E-only supplements are much higher than the recommended daily amounts, and high doses can increase the risk of bleeding and stroke

Vitamin E from natural sources is listed as “d-alpha-tocopherol” on food packaging and supplement labels. Synthetic (man-made) vitamin E is listed as “dl-alpha-tocopherol.”

The recommended daily amounts of vitamin E are:

  • Breastfeeding females: 19 mg
  • Adults, pregnant females, and teens 14-18 years: 15 mg
  • Children 9–13 years: 11 mg
  • Children 4–8 years: 7 mg
  • Children 1–3 years: 6 mg
  • Infants 7–12 months: 5 mg
  • Birth to 6 months: 4 mg

Some food and dietary supplement labels list vitamin E in International Units (IUs) instead of mg. 1 IU of natural vitamin E is equivalent to 0.67 mg. 1 IU of synthetic vitamin E is equivalent to 0.45 mg.
