What are the health benefits of Vitamin A?

Vitamin A (retinol, retinoic acid) is a nutrient that is necessary for eyesight, cell division, reproduction, and immunity. Antioxidant properties are also present in vitamin A. Antioxidants are chemicals created when your body breaks down food or is exposed to tobacco smoke or radiation, and they may protect your cells from the impacts of free radicals. Heart disease, cancer, and other disorders may all be linked to free radicals.

Many foods, such as spinach, dairy products, and liver, contain vitamin A. Foods high in beta-carotene, such as green leafy vegetables, carrots, and melons, are also good sources. Beta-carotene is converted to vitamin A in your body.Vitamin A can also be found in dietary supplements as retinyl acetate or retinyl palmitate (preformed vitamin A), beta-carotene (provitamin A), or a combination of preformed and provitamin A. Vitamin A is found in the majority of multivitamin/mineral supplements. There are vitamin A-only dietary supplements on the market as well.

Following are the health benefits of Vitamin A:

• Because vitamin A is involved in cell growth and development, it has a significant impact on cancer risk and prevention.
• Vitamin A is necessary for maintaining your vision. The vitamin is required to convert light into an electrical signal that can be transmitted to the brain.
• Vitamin A aids in the maintenance of your body’s natural defences. This includes the mucous barriers that help trap germs and other infectious agents in your eyes, lungs, gut, and genitals. It also plays a role in the formation and function of white blood cells, which are responsible for capturing and removing germs and other pathogens from your bloodstream.
• Vitamin A is necessary for both men and women to have a healthy reproductive system, as well as for embryos to grow and develop normally during pregnancy.
• All human tissues, including skin and hair, require vitamin A for growth. It aids in the creation of sebum, an oil that aids in the maintenance of moisture levels in the skin and hair.
