Vitamin A is a nutrient. The body needs it for good vision, skin maintenance, solid teeth, and healthy tissues and mucus membranes. It is of two kinds - beta-carotene and alpha carotene. Fruits, vegetables, and dairy products are rich natural sources of this vitamin. Vitamin A supplements are an alternative source of the nutrient.

Health benefits of vitamin A


A 2011 report in Cancer Causes & Control reads that vitamin A may create a wall against spread of breast cancer. The authors concluded this after a thorough analysis of 51 studies. Researchers are looking into what other types of cancer can be treated with vitamin A. A 2011 report in PLoS One suggests that the nutrient can be useful in the treatment of lung cancer. An older study (2004) in Lancet had also looked at the relationship between gastrointestinal cancer and vitamin A.

Ocular malaises

A 2011 report in the International Journal of Ophthalmology founds evidence of a connection between vitamin A and reduced symptoms of glaucoma. The study authors are of the opinion that vitamin A inhibits oxidative stress, thereby preventing the progression of glaucoma. The results were particularly in favor of liver oil - a food rich in vitamin A. Other studies suggest that vitamin A can be used in the treatment of age-related macular degeneration and cataracts.

Immune system

A 2007 study published in the Annals of Nutrition and Metabolism note that vitamin A may stimulate body’s defenses by strengthening the immune system. In contrast, they found, a lack of this vitamin leads to a weakened immune system.
