vitamin A

Vitamin A participates in different internal processes, but mainly it is related to the maintenance of normal visual functioning. It is liposoluble being absorbed through the intestine, and is found in the food we eat. It plays a role in the immune system and, above all, in maintaining good eye functioning. One of the forms of vitamin A is known by its name as retinol, which is part of the structures of the eye and its normal functioning.

As the American Academy of Ophthalmology says, the importance of providing nutrition to our organism is vital for our vision, since it is necessary for the maintenance of the retina and the cornea.

Today, the maintenance of eye care is more important than ever due to the great increase of hours that most of us spend in front of screens like the computer, television, cell phone… These habits have an effect on our eyes, causing dryness and eye fatigue. Therefore, keeping normal levels of this in our body has a positive effect on the condition of the mucous membranes, especially those that are part of the eyes, since moisture and lubrication are basic to maintain structure and function.

Why is vitamin A useful for our body?

There are many reasons why vitamin A is important in our bodies, however more commonly, vitamin A is involved in processes such as cell division, iron levels, the immune system, the skin, and as we have seen earlier, vision.

One of the most widely recognized qualities of this vitamin is its role in maintaining visual function. Its presence is essential for processes in the retina in order to have images in our brain. Likewise, another function in which vitamin A is present is the maintenance of our skin cells.

Maintenance of vision

To maintain good visual function, the presence of vitamin A is essential, because of its role in providing nutrition to parts of the eye such as the cornea and the retina. Vitamin A has a very important role in the function of vision, since it participates in the production of the pigments that are part of the retina and that allow us to see the light spectrum. In the same way, a normal level of vitamin A allows us to promote good vision, even in dim light.

It is also involved in the functionality and adaptation of vision when there are sudden changes in light.

What properties does vitamin A have on the skin?

The properties of it on the skin have resulted in recent years in the widespread use of vitamin A or retinol in moisturizers, or in a very high concentration in serums to promote its local effect. The main reason for its use on the skin is its effect on the maintenance of the skin and mucous membranes, as well as its participation in cell regeneration.

Where can we find it?

It is present in a natural way in the food we eat. It can be found in animal liver, whole milk, and other enriched foods. Carotenoids are the pigments that give color to some fruits and vegetables. So, a good choice to find vitamin A is yellow foods. Therefore, the foods with the highest content of this vitamin are carrots, lettuce, bonito, red peppers, and eggs.

Forms of Vitamin A in Foods

As for the vitamin A present in food, it can be found in two ways:

  • Retinol: that which comes from food of animal origin. Some of the foods containing it are: fish such as salmon, or the liver of the calf.
  • Carotenoids: found in fruits and vegetables, that is, in foods of vegetable origin. For example, the best known is the carrot, although we can also find others like spinach or pumpkin. The carotenoids are pro-vitamin A, which means when eaten our body transforms it into the active form of it

Recommended Daily Amount of Vitamin A
