Vitamin A - Basic Facts and Health Benefits

The term “vitamin A” makes it sound like there may be one unique nutrient known as Vitamin A” but that isn’t true. Vitamin A is a vast group of associated nutrients.

Every vitamin and mineral present us with wellness benefits, but these advantages are also one-of-a-kind and so they could also be supplied in specific approaches.Here are some facts about Vitamin A.


There are two basic types of vitamin A: retinoids, which are discovered in animal foods and carotenoids, which are found in plant sources. These two types aren’t simply chemically exceptional – they also furnish us with unique varieties of health benefits.

There are some thorough advantages of vitamin A that can most effective be received from the retinoid varieties of the vitamin. These retinoid varieties can also be important with respect to pregnancy and childbirth, childhood development, night vision, red blood cell production, and resistance to infectious diseases. Almost every of us need retinoid forms of vitamin A.

Just like the retinoid forms of vitamin A, the carotenoid varieties also provide us with health benefits. Most carotenoid variations of vitamin A are antioxidant and anti-inflammatory nutrients. Mostly specific carotenoids have a specific role to play in our wellbeing. For instance, the only carotenoids inside the retina of the human eye are lutein and zeaxanthin. Spinach, kale, and Swiss chard are examples of vegetables that are rich in lutein and zeaxanthin.

How Does Vitamin A Help Health?

While vitamin A is greatly known for its major role in vision, the retinoid types also participate in biological events regarding the immune system, inflammation, growth of tissues, reproduction, bone development, production of red blood cells, and creation of spermatozoa (male reproductive cells).

In food, the retinoid forms of vitamin A show up as retinyl esters. The body is often able to convert these retinyl esters into active forms of vitamin A together with retinol, retinal, and retinoic acid.

Retinal, which is the aldehyde form of Vitamin A, contributesto the synthesis of rhodopsin, and within the arrangement of chemical reactions that creates visual excitation, which is prompted by striking the rod cells. The other three pigments known as iodopsins, are located within the cone cells of the retina and are in charge for daytime vision.

Vitamin A performs a key function in support of immune processes. Our digestive tract can get exposed every day to potentially undesirable components like pesticides in meals, as well as undesirable micro-organisms. Our immune system is designed to support us from being harmed by these processes.

Vitamin A is required for cell growth and development. Even though the mechanisms through which vitamin A promotes cell growth and development are not fully understood, it is recognized that retinoic acid is necessary for the synthesis of many glycoproteins, which control cell adhesion, cell development, and cell differentiation.

Other Functions for Vitamin A

Vitamin A is vital for reproductive processes in both women and men and plays a role in bone metabolism. Vitamin A is known to be required for the creation of sperm or spermatogenesis.
