Provitamin A is a precursor of vitamin A and is also referred to as carotene. It is found in many plant foods and can be converted into vitamin A by the body.
Function and effect in the body
Vitamin A is important for healthy skin, eyes, bones and teeth. It also supports the immune system and reproduction.
Provitamin A can be converted into vitamin A, which plays an important role in eyesight and is an important nutrient for the growth and development of children.
Vitamin A is an essential micronutrient for the human body, and its deficiency can lead to a variety of health problems. A lack of vitamin A can cause night blindness, xerophthalmia (dry eyes), skin problems, weakening of the immune system and stunted growth.
It is important to ensure adequate intake of vitamin A either through diet or supplements to maintain good health. However, before you get any artificial provitamin A supplements or vitamin A supplements, you should have a conversation with your doctor to avoid overdose.

Other names for provitamin A
Provitamin A is also known as carotene because it consists of carotenoids. Another name is also retinoid precursor, as it is a precursor of vitamin A. In some cases, it is also simply referred to as vitamin A precursor.
Beta-carotene is a specific type of carotenoid and also a precursor of vitamin A, more precisely one of the most important precursors. Therefore, beta-carotene can be used as a synonym for provitamin A, but it is not the same as provitamin A, as it is merely a specific form. Other carotenoids such as alpha-carotene, lycopene or lutein can also be converted into vitamin A, but they are less effective precursors than beta-carotene.
Tips for sufficient intake
Provitamin A-rich foods include carrots, sweet potatoes, spinach, kale, peppers, and apricots. It is important to eat a balanced diet to get enough vitamin A.
