Do you know that is the importance of Vitamin A in the human body?
Let us tell you..
A vitamin is an organic molecule that is an essential micronutrient that an organism needs in small quantities for the proper functioning of its metabolism. Essential nutrients cannot be synthesized in the organism, either at all or not in sufficient quantities, and therefore must be obtained through the diet.
Vitamin A is essential for preserving your eyesight. The vitamin is needed to convert the light that hits your eye into an electrical signal. One of the first symptoms of vitamin A deficiency can be night blindness, known as nyctalopia. People with this condition can still see clearly during the day, but have reduced vision in darkness as their eyes struggle to pick up light at lower levels. In addition to preventing night blindness, eating adequate amounts of beta-carotene may help slow the decline in eyesight that some people experience as they age.

As vitamin A plays a vital role in the growth and development of your cells, its influence on cancer risk and position in cancer prevention is of interest to scientists.
Vitamin A plays a vital role in maintaining your body’s natural defenses. It includes the mucous barriers in your eyes, lungs, gut, and genitals, which help trap bacteria and other infectious agents. It’s also involved in the production and function of white blood cells, which help capture and clear bacteria and other pathogens from your bloodstream. It means that a deficiency in vitamin A can increase your susceptibility to infections and delay your recovery when you get sick. In countries where infections like measles and malaria are common, correcting vitamin A deficiency in children has been shown to decrease the risk of dying from these diseases.
Vitamin A deficiency may increase your risk of developing acne, as it causes an overproduction of the protein keratin in your hair follicles. It would increase your risk of acne by making it more difficult for dead skin cells to be removed from hair follicles, leading to blockages.
Eating enough vitamin A is also necessary for proper bone growth and development, and a deficiency in this vitamin leads to poor bone health. People with lower blood levels of vitamin A are at a higher risk of bone fractures than people with healthy levels.
Vitamin A is essential for maintaining a healthy reproductive system in both men and women, as well as ensuring the healthy growth and development of embryos during pregnancy. In pregnant women, vitamin A is also involved in the growth and development of many major organs and structures of the unborn child, including the skeleton, nervous system, heart, kidneys, eyes, lungs, and pancreas.
Hypervitaminosis A is caused by consuming too much-preformed vitamin A through your diet or supplements containing the vitamin. Symptoms can include nausea, dizziness, headaches, pain, and even death.
Vitamin A is vital for many essential processes in your body. It’s used to maintain healthy vision, ensure the normal functioning of your organs and immune system, as well as to establish average growth and development of babies in the womb.
Both too little and too much vitamin A could have adverse effects on your health. The best way to ensure you get the balance right is to consume vitamin-A-rich foods as part of your regular diet and avoid supplementing with excessive amounts.
