Vitamin A - Why is it good for you?

Date reviewed: 5 July 2015 | Date updated: 5 July 2015

Vitamin A is essential for healthy eyes as it helps the eyes to function properly in all conditions, even the dark. Vitamin A is essential in preventing night blindness.

Vitamin helps to prevent a leading case of blindness in the elderly called age-related macular degeneration (ARMD).

Vitamin A helps the immune system fight infection and illness by helping the epithelial tissues (the cells that make up the skin, line the mouth, nose, eyes, throat, lungs, digestive and urinary tracts and which keep out infective agents) grow and repair themselves. Without enough vitamin A, these cells become stiff, dry and much more likely to let their guard down and when that happens, germs can easily pass through them and into the body.

All humans (especially children and teenagers) need vitamin A for a wide range of body functions, including to help the body cells repair, grow properly and to keep bones and teeth strong.
