What Do You Know About Vitamin A?

Vitamin A can be classified into two main groups.


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, also known as β-carotene is a compound mainly found in the plant kingdom. The human body converts this compound to Vitamin A. It is derived mainly from carrots, pumpkin, sweet potatoes, and spinach. Monitoring for Vitamin A deficiency is a very long process and can take many months before any of the symptoms become noticeable.
