The infusion of vitamins has a great advantage over the oral application, namely the much higher concentrations of effective substances. The infusion delivers the vitamins directly into the blood stream in amounts that are far more effective than when taken orally. In addition to the benefits of prevention, the high amounts of vitamins can directly remove the symptoms caused by a lack of them. To benefit from the healing effects of vitamins, it is necessary to have such high concentrations of them in the blood that it is not possible to achieve this through taking them orally. This can only effectively be achieved through the intravenous application of infusions.
