Details about vitamin A. Why it is Important? Let's know!

Vitamin A is an essential vitamin needed for growth and development, cell recognition, vision, immune function, and reproduction

As an oral supplement, vitamin A mainly benefits people who have a poor or limited diet or who have a condition that increases the need for vitamin A, such as pancreatic disease, eye disease or measles. If you take vitamin A for its antioxidant properties, keep in mind that the supplement might not offer the same benefits as naturally occurring antioxidants in food.

The recommended daily amount of vitamin A is 900 micrograms (mcg) for adult men and 700 mcg for adult women.
Vitamin A is found in many foods, such as spinach, dairy products and liver. Other sources are foods rich in beta-carotene, such as green leafy vegetables, carrots and cantaloupe. Your body converts beta-carotene into vitamin A.

Cancer. The association between use of vitamin A supplements and reduced risk of lung, prostate and other types of cancer is unclear.

Vitamin A deficiency. People who have low levels of vitamin A appear to benefit most from vitamin A supplements. This kind of deficiency isn't common in the United States. Vitamin A deficiency causes anemia and dry eyes.
