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:

  1. retinoids, the pre-formed vitamin A that can be used by the body directly
  2. i carotenoids, which are precursors of vitamin A and must be converted to vitamin A before being used as such.

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 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.
