Vitamin A is a broad term that refers to a category of fat-soluble compounds that are vital to human health. The benefits of vitamin A is a variety of bodily functions, including maintaining good vision, ensuring normal immune and organ function, and assisting in the proper growth and development of babies in the womb.
Preformed vitamin A and provitamin A are two types of vitamin A compounds that can be present in both animal and plant foods. The active source of vitamin A is preformed vitamin A, which your body will use right away. The compounds retinol, retinal, and retinoic acid are present in animal products such as beef, chicken, fish, and dairy.
5 Benefits of Vitamin A
1. Improve Growth and Reproduction
One of the benefits of Vitamin A is necessary for both men and women to have a healthy reproductive system, as well as for the proper growth and development of embryos during pregnancy. It is essential for the growth and development of many main organs and structures in the unborn child, including the skeleton, nervous system, heart, kidneys, skin, lungs, and pancreas in pregnant women.

2. Improve Vision
Second benefits of Vitamin A is important for maintaining your vision. The vitamin is used to translate light into an electrical signal that can be sent to the brain. Night blindness, also known as nyctalopia, is one of the earliest signs of vitamin A deficiency. Vitamin A deficiency causes night blindness because the vitamin is a main component of the pigment rhodopsin.
In addition to avoiding night blindness, getting enough beta-carotene in your diet will help delay the loss of vision that some people face as they get older.
3. Lower Risk of Cancers
Higher intakes of vitamin A in the form of beta-carotene have been associated to a lower incidence of some cancers, including Hodgkin’s lymphoma, ovarian, breast, and bladder cancer, in clinical research. Following that, a high intake of vitamin A from plant foods has been linked to a lower risk of cancer.
Animal foods that contain active forms of vitamin A, on the other hand, are not related in the same way. Vitamin A supplements, on the other hand, haven’t proven to be as effective.
4. Reduce Acne Problem
Vitamin A deficiency has been linked to an increased risk of acne because it induces an overproduction of the protein keratin in hair follicles. This increases the chance of acne by making it more difficult to clear dead skin cells from hair follicles, causing blockages.
Any acne drugs dependent on vitamin A are also available with a prescription. One example of an oral retinoid that is useful in treating acute acne is isotretinoin. However, because of the potential for adverse side effects, this drug can only be used under medical supervision.
5. Support Bone
Nutrition, calcium, and vitamin D are important foods for preserving healthy bones as you get older.
However, adequate vitamin A consumption is required for proper bone growth and development, and a vitamin A deficiency has been related to poor bone health. In reality, people who have low vitamin A levels in their blood have a greater chance of bone fractures than those who have normal levels.
More controlled trials are required to validate what has been found in clinical research about vitamin A and bone health. Keep in mind that vitamin A status alone does not determine the likelihood of fractures, and that other important nutrients, such as vitamin D, play a role as well.
