A typical micronutrient intravenous infusion may contain a variety of substances. In most cases, the components of intravenous infusion of trace elements depend on the reason for its use; various diseases or medical conditions may require a specific combination of intravenous vitamins and minerals. In addition, the components of an intravenous vitamin pack can also be adjusted depending on the needs of the person receiving the infusion; people may tolerate certain ingredients better than others, or have an intolerance to certain substances. In general, some substances that may be contained in a typical intravenous vitamin infusion bag include the following: Vitamin C – There have been studies that have shown some benefits of intravenous vitamin C. In the critically ill, vitamin C given intravenously may help treat sepsis; it may also be useful in the treatment of certain types of cancer. In people in good health, intravenous administration of the vitamin may improve immunity and energy levels.45 Vitamin B Complex – Several vitamins make up the B complex group of vitamins. These include vitamin B1 (thiamine), vitamin B2 (riboflavin), vitamin B3 (niacinamide), vitamin B5 (dexpanthenol) and pyridoxine (vitamin B6). These vitamins play an important role in the processes occurring in the human body. Vitamin B12 – It is also known as cyanocobalamin. It performs many functions in the human body. However, its main function is to produce red blood cells. A deficiency in this vitamin can lead to a condition known as macrocytic megaloblastic anemia. Folic Acid – This vitamin is also known as folate. Like cyanocobalamin, folic acid helps in the development of red blood cells. Its deficiency can also lead to macrocytic megaloblastic anemia. Calcium – Calcium is essential for the development of strong and healthy bones. People who lack calcium in the body can develop a disease known as osteoporosis. Glutathione is an antioxidant that contributes to many key processes in the body. There are many other vitamins and micronutrients that can be included in an intravenous micronutrient infusion. As mentioned earlier, before starting intravenous administration of vitamins, it is recommended to consult with a healthcare professional; this will help ensure that the necessary vitamins and minerals are supplied in the right amount. With intravenous vitamin therapy, minerals and vitamins are introduced into the body through the veins. With this method of administration, vitamins and trace elements avoid metabolism in the intestine. In addition, substances enter the bloodstream faster and are distributed throughout the body, since they are not limited in absorption rate, as is the case with oral administration. Ultimately, only small amounts of vitamins and trace elements are wasted during intravenous vitamin therapy; most of it is absorbed and used by the body. Thus, the body receives all the benefits of vitamins and trace elements when administered through the veins, and not through the mouth.
