Vitamin A is a very important nutrient that helps our bodies in various ways, including but not limited to keeping our immune systems and eyesight functioning properly. In this article, we'll take an in-depth look at the various vitamin A benefits, its recommended intake, and dietary sources.

We all know that a balanced diet is essential for our health and well-being. And while we may pay attention to our daily intake of protein, carbohydrates, and fats, we often overlook the importance of vitamins. One vitamin that often flies under the radar is vitamin A, a fat-soluble group of compounds. Although it's often seen as a vitamin to improve skin and vision, its role goes far beyond. In this article, we'll explore the various vitamin A benefits, functions and other facts you need to know about maintaining healthy levels.

What is Vitamin A?

So, what is vitamin A? Vitamin A is not actually a singular substance, but a group of fat-soluble compounds called retinoids. You can find two types of vitamin A in food:

  1. Preformed vitamin A, found in animal-based products like dairy, liver, and fish.
  2. Provitamin A carotenoids, found in plant-based products such as fruits, vegetables, and oils.

Your body needs to convert both forms of vitamin A into retinal and retinoic acid, the active forms of the vitamin, in order to use them. Because it's fat-soluble, vitamin A is stored in your body tissue for later use.

Functions of Vitamin A in Your Body

Understanding the role of vitamin A and the importance of maintaining adequate levels can greatly benefit your pursuit of good health.

1.    Vision: Vitamin A is crucial for maintaining good vision. Here’s why:

  • Without enough of it, you might experience visual disturbances. In your eyes, a type of Vitamin A known as retinal combines with a protein called opsin to create rhodopsin, which helps you see colours and navigate in low-lighting conditions.
  • It also protects and supports the outer layer of your eye, called the cornea, and the thin membrane called the conjunctiva that covers the surface of your eye and the inside of your eyelids.
  • By making sure you get enough vitamin A in your diet, you can help safeguard against eye diseases like age-related macular degeneration.

2.    Immunity: Vitamin A is crucial for a strong immune system. Without enough of it, our ability to fight off infections can be compromised. Infections may last longer and could be more severe.

3.    Skin health: An important function of vitamin A is the maintenance of healthy skin, helping in the daily replacement of skin cells. A diet rich in carotenoids can also effectively shield your skin from harm caused by air pollution and UV radiation, helping to prevent skin cell damage and ageing.

4.    Cell Growth and Maintenance: Vitamin A is also important for the growth of epithelial cells, which cover our skin, body cavities, and blood vessels. It is also important for maintaining the integrity and function of surface tissues like the intestines, lungs, bladder, and inner ear.

5.    Antioxidative Properties: Provitamin A carotenoids possess antioxidant properties that help safeguard our cells from oxidative damage, which is associated with chronic conditions like diabetes, cancer, heart disease and cognitive decline.

6.    Fertility and foetal development: Vitamin A plays a crucial role in the reproductive processes of males and females by aiding in the development of sperm and eggs. Additionally, it is essential for maintaining a healthy placenta, supporting fetal tissue development, and promoting overall fetal growth.

Daily Recommendations for Vitamin A

The vitamin A daily requirement is 1000 mcg/day for men and 840 mcg/day for women. It’s important to note that overexposure to this nutrient can be very toxic. It goes without saying that before deciding to take any supplements, you should first seek professional medical advice from a qualified healthcare practitioner.
