Can You See the Benefits of Vitamin A?

Making good food choices can help keep your eyes healthy. Vitamin A promotes normal vision and it also helps your eyes see normally in the dark, helping adjust to lower levels of light. In addition, vitamin A also influences the immune system, is essential for bone growth and affects both male and female reproductive processes.

The recommended daily allowance of vitamin A is 3,000 International Units for men and 2,310 IU for women 14 and older. IUs are listed on food labels and dietary supplements.

Good sources of vitamin A include sweet potatoes, carrots and dark, leafy greens, as well as eggs, tomatoes and fortified milk.

For more information on food sources of vitamins your body needs, consult a registered dietitian in your area and visit the American Dietetic Association Vitamins and Nutrients section.
