Monday, 23 December 2013 12:46 AM

Vitamin A is an essential vitamin that benefits cell growth, reproductive health, and the immune system. It is particularly beneficial for good vision and the eyes. This fat-soluble vitamin is present in normal diet. Fruits and green leafy vegetables are excellent sources of vitamin A. Supplements of vitamin A are also available. The two types of vitamin A supplements available are retinoids and beta carotene. Retinoids are derived from animal products (fish, dairy products, meat, etc.) while beta carotene is derived from plants (fruits and vegetables). Retinoids are the active form that can help prevent diseases while beta carotene is usually available to the body through balanced diet.

Retinol, or vitamin A, is closely identified with the retina of the eyes. It helps the eyes differentiate between light and dark. Vitamin A protects the surface of the eyes, the skin of the eyes and its membrane from infection caused by bacteria and virus. Vitamin A reduces the risk of eye infections and eye diseases. Vitamin A helps promote good vision. It is especially effective in promoting vision in low light.
Apart from the eyes, vitamin A is important for developing and maintaining a good immune system. It fights respiratory diseases and is even beneficial in treating leukemia. Besides this, studies find vitamin A useful for treating a number of diseases like cataract, HIV, and cancer. Vitamin A helps in fighting against cancer by inhibiting the production of DNA in cancerous cells. Regular consumption of an adequate amount of vitamin A enhances immunity and improves the body’s ability to defend itself against viruses and infections.
Creams containing retinoids are quite the rage among people battling skin conditions such as psoriasis, ketosis, and acne. Retinoids help maintain good skin, prevent skin diseases, and offer anti-aging benefits. Retinoids are also good for teeth. Retinoids are used in oral and topical form for treating acne and other skin conditions. Oral retinoids are useful in treating measles.
Dry eyes indicate low levels of vitamin A. Deficiency of vitamin A can lead to multiple diseases including digestive diseases, night blindness, and mucous membrane diseases. A healthy diet can provide a sufficient amount of vitamin A but doctors can advise you if you need to take supplements.
While the deficiency of vitamin A can cause various diseases, excess can also cause sickness and even birth defects. The recommended level of intake is 10,000 international units for adults 19 and older.
