According to the World Health Organisation (WHO), vitamin A deficiency is the leading cause of preventable blindness in children worldwide. It increases the severity and risk of dying from infections like measles and diarrhoea which are common infections affecting children under 5 years old. In South Africa there is a Vitamin A supplementation program that was initiated for children under 5 years to help combat this problem of vitamin A deficiency
For adult’s vitamin A deficiency raises the risk of anaemia and death in pregnant women and negatively impacts the foetus by slowing growth and development. Vitamin A deficiency in adults can cause night blindness which is not a common condition.
Taking in too much vitamin A can for longer periods is associated with adverse effects, especially during pregnancy and in the elderly

- People with wounds and acne may have lower blood levels of vitamin A and benefit from treatment with higher doses of the vitamin.
- Children – can cause severe visual impairment and blindness, and significantly increases the risk of severe illness, and even death, from such common childhood infections as diarrhoeal disease and measles
