Vitamin A is one of those “underdog” vitamins that not many people are well aware of until and unless they are faced with a side effect because of their deficiency. Not just for the eyes, this Vitamin goes above and beyond that.

In this article, we are going to glance through the various Vitamin A benefits for health, skin as well as hair that not many people are often aware of.

What is Vitamin A?

Vitamin A, otherwise known as Retinol, is an essential Vitamin that is needed by the body for the overall growth and development of the body. It also plays a very crucial role in cell recognition, acute vision, and reproduction and even on one’s immune system.

While the majority of the people often tend to only recognize Vitamin A just because of its functions as Vitamin, it also has beneficial functions as a hormone which helps in an expression of genes in the body. The presence of this Vitamin in the body has effective impacts on the salient functions of the heart, lungs, kidney and a few other important organs in the body.

With all that being said, it is necessary to understand for a fact that there are a few sub-categories of Vitamin A based on their forms and their presence in the body.

Some of the common types of Vitamin A include:

ProVitamin A: An inactive form of the active Vitamin A which is stored in the body and saliently converted to Vitamin A as per the body requirements. It is found in a number of fruits and vegetables and a number of other plant based products.

Retinol: This is the active and one of the most predominant variants of Vitamin A which is found in the blood. The storage form of the Vitamin A is the retinyl palmitate. It is found in animal derived foods.

Beta-carotene: This is yet another inactive precursor of Vitamin A which is predominantly found in plant sources.

How is Vitamin A Good for You?

Vitamin A is one of those few Vitamins that doesn’t just limit their benefits to the common realms of health but extend it to boost one’s overall well being. Vitamin A is loaded with essential antioxidants which help in ensuring the maintenance of the levels of oxidative stress in the body which is definitely something that is often the primary contributing factor to a number of underlying health ailments.

While the deficiency of this specific Vitamin can end up resulting in severe consequences ranging from night blindness to lack of growth and scaly skin, the excess of it in the body can inflict negative implications as well which is why it is necessary to be assured of the correct balance of it.

Yet another reason why Vitamin A is actually beneficial for your health is because of fact that it is a fat soluble Vitamin and is an antioxidant on top of that. The presence of Vitamin A is beneficial for one’s health and longevity.

Given the fact that there is predominantly two variant of Vitamin, an active and a precursor, both of these have different sources that they are derived from.

Some of the common sources of Retinol, or the active form of Vitamin A include:

Some of the common sources of carotenoids (antioxidant form of Vitamin A) which is later converted into Vitamin A in the body include:

How Much Vitamin A Should One Consume Per Day?

The intake of Vitamin A is predominantly dependant on one’s age and sex alike. It varies depending on these two criteria. The Vitamin A which is primarily sourced and consumed via the plant or animal derivatives are often considered and measured as retinol activity equivalents (RAE).

According to standard norms,

1 RAE = 1 mcg of retinol + 12 mcg of beta-carotene

In order to make it easier to understand, we have made a tabular approach to explain the optimal daily consumption of Vitamin A, based on age and sex of an individual.
