In contrast to absorbing fluids via the digestive system, intravenous (IV) hydration is a minimally invasive treatment that delivers fluids directly into circulation. In IV vitamin therapies, vitamins, medicines, and other dietary supplements are infused with IV fluids for accelerated absorption. Energy is provided by ingredients like vitamins B12, B5, and B6, while lysine, zinc, and vitamin C reduce the length of sickness by treating the cause rather than just the symptoms. Only board-certified registered nurses with extensive training and experience give IV hydration and IV vitamin therapies to assure their safety and efficacy. An accurate assessment of the patient's requirements and goals is the first step in any IV hydration and IV vitamin therapy.
