Vitamin A “Miracle vitamin” List of alerting benefits of vitamin showing vitamin A is a must have ingredient for every person of any age
Vitamin A is a fat-soluble vitamin that is essential for major systems of our body. This vitamin includes a group of closely related compounds called retinoids and carotenoids. There are different sources of vitamin A
Benefits of vitamin A
Vitamin A is needed for our vision, reproduction, cell differentiation, skin and mucous membrane, protects from cancer, boosts immunity and cures anemia by increasing RBC-count in our body. It is a miracle that nature has provided us a single vitamin with so many benefits, isn’t it? Vitamin A benefits our overall body in many ways most of them are following:-
Retinol is a form of vitamin A obtained mainly from animal sources. This retinol is absorbed from the intestine into blood travels into eyes in the rods cells. In rods retinol forms rhodopsin which is the visual pigment of rods providing vision in dark because rods are mainly involved in the vision at night. Deficiency of vitamin A leads to the development of night blindness.
Vitamin A is required for growth and differentiation of embryo. Vitamin A is also needed for proper development of gametes in male and females. In males, this vitamin helps in the differentiation of immature spermatogonia into mobile and differentiated sperms. In females, this vitamin varies in its deficiency from mild to the severe form affecting development of gametes. Deficiency of vitamin A can cause adverse effects on reproductive system in both males and females as I discussed in
This miracle vitamin boosts immunity preventing us from many diseases and pathogens. It does this by helping information of lymphocytes which are main components of our immune system and, maintaining the mucosal lining of our major tracts e:g digestive tract. It causes the formation of B and T lymphocytes from stem cells increasing our immunity and prevents invasion of pathogens into our body by maintaining mucosal barriers. Deficiency of vitamin A decreases our immunity leaving us vulnerable to many infectious agents.
Skin and mucous membrane.
Vitamin A keeps our skin healthy and maintains its moisturization and prevents it from getting dry. Vitamin A also maintains mucus lining of major tracts like reproductive tract, digestive tract and respiratory tract preventing these tracts from getting infected by the invasion of infectious agents.
Acne and psoriasis:
Vitamin A helps in relieving conditions like acne and psoriasis by making new skin cells. Vitamin A is applied topically in conditions like acne as its treatment. Deficiency of this vitamin aggravates acne and psoriasis. Not all available forms of vitamin A are good for health.
NOTE: Pregnant women should not use vitamin A supplementation.
Vitamin A increases gene expression in the body by causing increased conversion of genes into desired proteins through translation and transcription. So, producing desired proteins and enzymes that help in boosting our metabolism.
Studies have shown that those people who consume enough vitamin A have reduced the incidence of cancers. Mainly cancers belonging to GIT tract like colon cancer, esophageal cancer. Those women which take enough vitamin A are at lower risk of developing breast cancer. Besides these women are also at low risk of developing other cancers like colon and pancreas.
Vitamin A causes differentiation of RBC’s from stem cells(precursors of RBC’s). Thus, increases RBC count in blood, precisely raising the Hb (hemoglobin). Which ultimately results in better transport of oxygen in the blood.Thus, curing anemia.
Vitamin A acts as an antioxidant, another amazing feature of this vitamin. Other vitamins acting as antioxidants are vitamin C and E. Antioxidants:-
- Protect us from deadly effects of free radicals preventing us from the oxidative effect of these radicals.
- Slow down the aging process( The Major problem for humans!)
