Beta-carotene is an antioxidant contained in a diet rich in vegetables, fruits and whole grains, explains WebMD. However, too many antioxidants, including vitamin A, may do harm to the body, so it is important for people to get the correct amount through food and supplements. Doctors recommend that women get about 700 micrograms of vitamin A each day, and men should get about 900 micrograms daily.

People take vitamin A for a number of reasons, states WebMD. For instance, oral and topical retinoids are often used for acne or skin issues, such as wrinkles. When taken orally, vitamin A may treat measles or improve dry eyes. Vitamin A also is a treatment for a certain type of leukemia, and as of 2015, researchers are studying it as a treatment for cancer, HIV and cataracts.

Most people don't need to take vitamin A supplements, as a healthy diet supplies enough, states WebMD. However, those who have vitamin A deficiencies must take supplements. People with vitamin A deficiency often include those with poor diets or those who have digestive disorders or other conditions.
