The term ‘vitamin A’ refers to a group of antioxidant compounds. In the food we eat, vitamin A is derived from two sources; animal (known as retinol), and from fruits and vegetables (known as provitamin A carotenoids).

Not only does vitamin A promote general health, it also helps protect the eyes and it might help slow the progress of more serious eye conditions. Vitamin also A protects the surface of the eye (cornea), by lubricating the cells which is why vitamin A is often added to eye drops.

Luckily, Vitamin A is easy to obtain through diet and has many other health benefits such as bone growth, skin health and keeping your immune system healthy.

Researchers at the National Eye Institute in the US discovered that taking high levels of a combination of nutrients (including beta-carotene which your body converts into vitamin A) and zinc can reduce the risk of developing advanced age-related macular degeneration (AMD) by around 25% over a six year period.1

Foods that are rich in vitamin A include brightly coloured fruits and vegetables such as oranges, apricots, carrots, sweet potatoes, pumpkins, as well as eggs and other dairy products.
