Vitamin A is a group of fat-soluble compounds that can be differentiated into two categories, depending on whether the food source is an animal or a plant: Vitamin A found in foods that come from animals is called ?preformed vitamin A? or ?retinol?; it is one of the most active forms of vitamin A. Vitamin A found in fruits and vegetables is called ?provitamin A carotenoid?, which can be cleaved into retinol in the body; the carotenoid ?beta-carotene? is most efficiently converted into retinol, making it an important vitamin A. High doses of vitamin A (retinol) supplements have been used successfully to treat an inherited eye disease (retinitis pigmentosa) and the symptoms of some severe skin disorders (psoriasis and acne). The recommended daily intake of vitamin A varies according to age, sex, risk group and other criteria applied in individual countries: 700?1000 micrograms (mcg) Retinol Equivalents (RE) per day for men, 600?800 mcg RE/day for women. Vitamin A deficiency usually results from inadequate intake of foods high in vitamin A or beta-carotene, a precursor of vitamin A. The earliest symptom of vitamin A deficiency is night blindness. Groups at risk for insufficient vitamin A supply are mainly pregnant and breast-feeding women, newborns, children with frequent infections, the elderly and people who avoid animal-derived foods. The richest food source of preformed vitamin A is liver, with considerable amounts also found in egg yolk, whole milk, butter and cheese. Provitamin A carotenoids (e. G. Beta-carotene) are found in carrots, yellow and dark green leafy vegetables (e. G. Spinach, broccoli), pumpkin, apricots, melon, and palm oil.
