What Do You Know About Vitamin A?

Vitamin A can be classified into two main groups.

Retinol

Vitamin A, also known as “Retinol”, is a vitamin which is considered fat soluble and is derived mainly from animal sources. Why is it called Retinol? It’s because it creates the pigments which are present in the Retina of the human eye. In a human eye, the substance “retinal” is a light absorbing substance with a very specific metabolite, which enhances vision, especially when the light is low.

Beta-Carotene

It is derived mainly from carrots, pumpkin, sweet potatoes, and spinach.
