Retinol activity equivalent (RAE) is the most widely used measure for vitamin A content in foods. It takes into account the different forms of vitamin A found in foods and their varying levels of activity in the body. Active retinol unit (ARU), Retinol functional equivalent (RFE), and Functional retinol unit (FRU) are not commonly used measures for vitamin A content in foods.
