The body needs small daily quantities of vitamins and minerals, which are usually obtained from the diet. Intravenous vitamins are used for a few serious medical conditions (eg, malabsorption syndromes with severe vitamin depletion, Wernicke's encephalopathy or critical illness). Intravenous drips containing high doses of various vitamins and minerals (eg, the so-called 'Myers' cocktail') have been promoted in popular culture to 'reduce stress', 'increase energy' or 'boost immunity', with claims that the intravenous route allows faster absorption of vitamins into the bloodstream than if they are taken orally. There is a lack of high-quality evidence to suggest that high-dose vitamin infusions are necessary or offer any health benefit in the absence of a specific vitamin deficiency or medical condition. There may be harms from taking high (non-physiological) quantities of some vitamins and minerals. Licensed forms of injectable vitamins that are prescription-only medicines should not be advertised to the public and should only be supplied and administered by appropriately qualified healthcare professionals.
人体需要少量的维生素和矿物质，通常可从饮食中获得。静脉注射维生素用于少数严重的医疗状况（例如，严重维生素缺乏的吸收不良综合征、Wernicke 脑病或危重病）。在流行文化中，含有高剂量各种维生素和矿物质的静脉滴注（例如，所谓的“迈尔斯鸡尾酒”）被宣传为“减轻压力”、“增加能量”或“增强免疫力”，声称静脉途径可使维生素更快地被吸收到血液中，而不是通过口服。缺乏高质量的证据表明，在没有特定维生素缺乏或医疗状况的情况下，大剂量维生素输注是必要的或提供任何健康益处。服用某些维生素和矿物质的高（非生理）剂量可能会有危害。仅限处方的注射用维生素应禁止向公众宣传，并且只能由合格的医疗保健专业人员供应和管理。
