This fat-soluble vitamin A belongs to a whole group of substances with diverse biological functions. In its pure form it is only contained in animal products. As provitamin A (beta-carotene), however, it is present in plant food and is then partially converted to retinol in the body.
Retinal, which belongs to the group of substances of vitamin A, is important, especially for the eyes, as it influences the formation of various visual dyes, which is important for contrast vision, for example, i.e. the perception of light and dark contrast. A deficiency is then the so-called night blindness.
Furthermore, vitamin A is good for the skin because it provides elasticity by converting the retinol in the skin into vitamin A acid. It stimulates cell growth in the skin and in the mucous membranes. Vitamin A is often used in cosmetic products as an anti-aging agent, as it is said to slow down cell aging.
Beta-carotene can be processed better if it is eaten together with fat. Because only as much of it is converted into vitamin A as the body needs.
One should be careful not to take too much vitamin A, because an overdose cannot be processed by the body. It can cause nausea and vomiting, headaches, high blood pressure and hair loss. Such hypervitaminosis A, however, develops only after a prolonged intake with a high intake.
