Vitamin A, also known as retinol or axerophthol, is one of the best known and most important vitamins. It is a fat-soluble vitamin that plays a key role in many basic biological functions, including reproduction, the immune system, vision and cell-to-cell communication. Its deficiency can lead to a variety of health problems, including severe vision problems, dry skin, loss of appetite and a weak immune system.

Retinol or axerophthol is found in many foods and supplements. It is added as a supplement or preservative to many products. It is known for its positive effects on the skin and is widely used in the cosmetic industry, especially in anti-ageing products and products for acne-prone skin. In addition, it is also used in the food industry. For example, vitamin A is included in many children's nutritional supplements and specialised foods for athletes. It is also contained in nutritional supplements for pregnant women, where it contributes to normal fetal development. In terms of food, vitamin A is mainly found in fish oil, liver, milk, cheese and egg yolk. It can also be found in certain fruits and vegetables such as carrots, broccoli, apricots and spinach.
