Vitamin A or retinol is a vitamin found in fruits and vegetables that is necessary for the body to function. In addition, it is found in animal foods such as liver and egg yolk. It plays an important role in supporting the visual process and the development of the growing organism.
The use of vitamin A in medicine is very popular. It is used for the maintenance of good vision and the proper functioning of the immune system. As vitamin A is involved in bone development, it is especially important for children. Administration of this nutrient is also common in herpes, acne, psoriasis and bronchitis, for example.
Vitamin A is known for its supportive properties. In particular, it helps to see in low light. This is because vitamin A is found in the light-reactive molecule in the eye.
The use of vitamin A helps prevent vision deterioration with age. In addition, vitamin A helps treat dry eye syndrome and prevent macular degeneration. Vitamin A deficiency can cause a variety of vision problems, such as dry eye syndrome, vision problems in the dark, and an increased risk of eye infections.
Although vitamin A is needed by the body, it should only be taken in small amounts.
Excessive consumption may cause headache, cracked lips, blurred vision and hair loss. Particular caution should be exercised in pregnant women, as side effects of an overdose of this nutrient include fetal malformations.
