Vitamins intakes cannot be absolutely established; they depend on basic composition of the diet, ecological conditions and physiological status of the subject. Nevertheless, approximate norms can be established, which avoid deficiencies or overdosages. Dietary and epidemiologic surveys, assays on volunteers conducted the commissions of F.A.O./O.M.S. Experts and National Authorities to propose values with a practical consensus for vitamins A, B1, B2, PP, P, C, D, B12 folates and some other factors.
维生素摄入量无法绝对确定；它们取决于饮食的基本组成、生态条件和个体的生理状况。然而，可以制定大致的标准，以避免缺乏或过量摄入。通过饮食和流行病学调查、粮农组织/世界卫生组织专家委员会及各国当局对志愿者进行的检测，就维生素A、B1、B2、PP、P、C、D、B12、叶酸及其他一些因素提出了具有实际共识的数值。
