Benefits Of Vitamin ASo what is Vitamin A? Vitamin A, also known as retinol, is a fat soluble vitamin that is required in small amounts in the body. The benefits of Vitamin A include:
Sources Of Vitamin A FoodsVitamin A from nature comes in two main forms, the first is retinol. Sources of retinol include liver, dairy products and eggs. The second form of vitamin A is beta-carotene. Beta carotene is converted by the body to retinol when needed and is found in brightly coloured fruits and vegetables. Beta carotene is converted to vitamin A at a ratio of approximately 6 to 1. Vitamin A Foods include, liver, eggs, carrots, tomatoes, spinach, cod liver oil, sweet potato, leafy vegetables, mango, papaya and apricot.Vitamin A Deficiency SymptomsVitamin A deficiency is not very common in developed countries but is more common in developing countries. It can be due to either inadequate dietary intake of vitamin A foods, or malabsorption. Vitamin A deficiency symptoms initially present as impaired vision particularly night-blindness. If the deficiency is left untreated, it may result in a condition known as xeropthalmia which is characterised by excessive drying of the conjunctiva and may result in total blindness. Other symptoms include a decrease in immunity, rough skin and growth retardation in children. Vitamin A is available in the form of a micro-dispersable emulsion, known as mycellized vitamin A. This form of the vitamin is useful when large doses of the vitamin are required since it can be easily absorbed. It is thought to be useful for asthma, acne, skin conditions and immune disorders.Vitamin A ToxicitySince Vitamin A can be stored in the body, Vitamin A toxicity can result easily. Symptoms of acute toxicity may include nausea and vomiting while chronic toxicity causes changes in skin, hair, liver test results and birth defects. It is always recommended to consult a healthcare provider before starting any supplement so as to get the most appropriate dose.
