Vitamin A
Support for vision, skin, and the immune system
Vitamin A plays an important role in various processes in the body. It contributes to maintaining normal vision and supports eye health. This makes it essential for the proper functioning of the retina and for clear vision, both during the day and in low light.
Additionally, Vitamin A helps maintain healthy skin and normal mucous membranes. Mucous membranes are found in the respiratory tract, intestines, and eyes, and they form a protective barrier against external influences. Vitamin A also contributes to the normal function of the immune system, which helps protect the body from harmful external factors.
Sources of Vitamin A
Vitamin A is found in both animal and plant-based foods. Animal sources contain retinol, the directly usable form of Vitamin A. Foods such as liver, fish oil, full-fat milk, eggs, and fortified margarine are good examples of this.
Plant sources contain provitamin A in the form of carotenoids, the most well-known being beta-carotene. The body can convert beta-carotene into active Vitamin A. Vegetables and fruits with an orange or dark green color are rich in this, such as carrots, sweet potatoes, pumpkin, spinach, and kale.
A varied diet with both animal and plant-based foods ensures you get enough Vitamin A.
Forms and Absorption
Vitamin A comes in different forms, with retinol being the most active. Retinol is directly used by the body and is mainly found in animal products.
Carotenoids like beta-carotene must first be converted by the body into Vitamin A. This conversion happens in the small intestine and liver. The efficiency of this conversion varies from person to person and depends on factors such as genetic predisposition, gut health, and the presence of fat in the diet. Because Vitamin A is fat-soluble, its absorption is enhanced when consumed with a fat source, such as olive oil, nuts, or avocado.
For optimal absorption of Vitamin A, it is important to follow a varied diet that includes both animal and plant-based sources of this vitamin.
synonyms for Vitamin A: Vitamin A, retinol, retinyl acetate, retinyl palmitate, beta-carotene and mixed carotenoids.
