Vitamin A plays a vital role in bone growth, reproduction and immune system health. It also helps the skin and mucous membranes repel bacteria and viruses more effectively. It is essential to healthy vision and may slow declining retinal function in people with retinitis pigmentosa. Here are the Top 10 Benefits of Vitamin A.
Learn Top 10 Benefits Of Vitamin A:
Vitamin A is a group of unsaturated nutritional organic compounds that includes retinol, retinal, and several provitamins A carotenoids (plant pigments responsible for the bright red, yellow and orange hues in many fruits and vegetables).
Vitamin A is a fat-soluble vitamin that is naturally present in many foods. Vitamin A is important for normal vision, the immune system, and reproduction.
Vitamin A also helps the heart, lungs, kidneys, and other organs work properly. Moreover, Vitamin A – include the basic natural ingredients required for the formation and maintenance of teeth, bones, soft tissue, white blood cells, the immune system and mucous membranes in your body.
NOTE: Vitamin A is a fat-soluble vitamin, and like other fat-soluble vitamins, it has the potential to be harmful – if taken in very high doses.
Here are the Top 10 Benefits of Vitamin A for maintaining a good health:
10. Protects Eye Health
Vitamin A plays such a critical role in eye health because it is actually part of the critical eye structure – Rhodopsin molecule.
Rhodopsin molecule is a (biological pigment found in the rods of the retina – and is extremely sensitive to light, and thus enables vision in low-light conditions).
Rhodopsin is activated when light shines on the retina, and it sends a signal to the brain, which results in vision. Vitamin A is part of rhodopsin that absorbs the light and is also needed for cells in the membrane of the cornea (the transparent layer forming the front of the eye).
9. Supports Cell Growth
Vitamin A is needed for growth and for cellular differentiation (a process by which new cells are created and cells become specialized in order to perform different functions).
Humans have many different types of cells with different jobs, such as blood cells that carry oxygen and nerve cells that transmit signals to all parts of the body – Because of this, vitamin A is critical for the growth of cells for better organ formation.
8. Provides Antioxidant Protection
Vitamins A, C, and E are considered antioxidant nutrients.
This means vitamin A can help protect body cells from damage from carcinogens (a substance capable of causing cancer in living tissue), toxins (a poison acting as an antigen in the body) and oxidative damage (biological system’s ability to readily detoxify or to repair the resulting damage).
Thus, Antioxidants are intimately involved in the prevention of cellular damage – the common pathway for cancer, aging, and a variety of diseases.
7. Immune Health
6. Prevents Premature Skin Damage
Vitamin A is essential for maintaining a healthy skin – lack of vitamin A in the body will lead to the drying, scaling, and follicular thickening of the skin. Vitamin A also keeps the wrinkles on your skin away.
5. Support Skin Re-Growth
Vitamin A is necessary for wound healing and skin re-growth. It is needed to support all of the epithelial (skin) cells both internally and externally and is a powerful aid in fighting skin cancer.
4. Fights Inflammation
4. Fights Inflammation
Vitamin A has antioxidant properties that neutralize free radicals in the body that cause tissue and cellular damage.
Vitamin A intake can help to lower the risk of certain types of food allergies (e.g: flushed skin, vomiting, diarrhea, abdominal cramps) or rash because it helps to prevent this dangerous overreaction.
3. Helps Prevent Cancer
According to a study conducted at the University of York, Vitamin A – intake could help treat several forms of cancer thanks to the vitamin’s ability to control malignant cells in the body.
2. Prevents Respiratory Infections
Vitamin A helps in preventing respiratory infections in the body. Respiratory infections can occur because the body’s immunity is impaired by the lack of vitamin A. Moreover, in children growth, retardation and infections are common among children due to Vitamin A deficiency.
1. Safe Pregnancy
For pregnant women, the vitamin A demand is the highest during the last trimester, as most often, women suffer from vitamin A deficiencies during this time.
Lack of Vitamin A deficiency in a pregnant woman can lead to night blindness if her Vitamin A – intake is not sufficient in her body.
