Vitamin A is a fat-soluble vitamin essential for vision (particularly night vision), immune function, and skin and mucous membrane health. Deficiency, though uncommon in developed countries with varied diets, can occur with fat-malabsorption conditions or very restrictive diets, and can cause vision problems (including night blindness) and increased infection risk.
