Vitamin A

Vitamin A holds the common name Retinol, also called as Retinoid, Retinoic acid, Retinyl, Palmitate, and Retinyl Acetate. Naturally, there are two types of vitamin A – they are Retinoid and Pro-vitamin A. Retinoid gets more attention as the human body absorbs it easier than other types. Pro-vitamin A has the need to change into Retinoid to absorb by the body. A human body has the capacity of changing this process. It is a boon to vegetarians as we get retinol from meat and we get only pro-vitamin from vegetables and fruits. It is also called as carotenoid and beta-carotene. We have two types of vitamins, fat-soluble and fat dissoluble. Vitamin A belongs to fat-soluble types so we need fat in our body to make it absorbed by the body. Only with the help of fat, vitamin A can do miracles to our body. This vitamin has the property of staying in our body for a long time so this vitamin can be consumed once in a while.
