Vitamin A is one of the most important fat-soluble vitamins, with roles spanning vision, immune defence, skin health, and cell growth. Despite its importance, it's a nutrient that comes with a bit of nuance — because "vitamin A" in food actually refers to two distinct things: preformed vitamin A (retinol), found in animal products, and provitamin A carotenoids (primarily beta-carotene), found in plant foods. The body converts beta-carotene to vitamin A as needed, but the conversion is less efficient than getting retinol directly from food.The recommended daily intake is 700mcg for adult women and 900mcg for adult men, expressed as retinol activity equivalents (RAE).
