La Vitamin A, or retinol, is a fat-soluble vitamin that is stored in the liver and can be taken from foods of animal origin and red, yellow and orange fruit and vegetables.
Vitamin A can be taken in the diet in two different forms:
- i retinoids, the pre-formed vitamin A that can be used by the body directly
- i carotenoids, which are precursors of vitamin A and must be converted to vitamin A before being used as such.

Vitamin A: the risks
In Europe we do not have serious problems of vitamin A deficiency.

In fact, there are few cases of hypervitaminosis A from dietary excess reported in the scientific literature. At high doses, vitamin A has a teratogenic effect, that is, it produces abnormalities or malformations in the embryo (assumption recommended for women = 600 μg / day and not to exceed 3000 μg / day).
The National Institute of Health does not recommend supplements containing vitamin A.
Is there a risk of vitamin A overdose?
The richest food in vitamin A is the liver. The frequent and habitual consumption of liver in pregnant women or those who expect it is therefore not recommended.
