Vitamin A plays a crucial role in many bodily functions, particularly for night vision and strengthening the immune system. It exists in two main forms: retinol, directly available in animal products, and beta-carotene, a precursor found in fruits and vegetables.
Vitamin A: Retinol and Beta-Carotene
Retinol is an active form of vitamin A, primarily found in animal-derived foods such as:
-
Fish livers (cod liver oil)
-
Whole dairy products
-
Eggs
Beta-carotene, on the other hand, is a plant-based form, a precursor to vitamin A, present in many fruits and vegetables, including:
-
Sweet potatoes
-
Carrots
-
Spinach
-
Pumpkin
Why is Vitamin A essential?
Vitamin A is essential for maintaining good night vision. It also plays an important role in cell growth, embryonic development (especially in pregnant women), and strengthening the immune system.
Vitamin A is stored mainly in the liver, which allows the body to effectively manage its intake.

Beware of excess Vitamin A
While vitamin A deficiency should be avoided, an excess can also have harmful effects. It's important to follow official nutritional recommendations, particularly regarding the quantities of vitamin A provided by food supplements, to prevent any risk of overdose.
In conclusion
Vitamin A, in its various forms (retinol and beta-carotene), is a key element for maintaining good visual, immune, and cellular health. Make sure to integrate a variety of vitamin A-rich foods into your daily diet to benefit from its many advantages.
