IV therapy involves the infusion of fluids, vitamins, minerals, and other nutrients directly into the bloodstream through a vein. This bypasses the digestive system, allowing for rapid absorption and utilization of the nutrients by the body. The composition of the IV solution can vary widely depending on the individual's needs and the goals of the therapy. Common ingredients include electrolytes, vitamins such as vitamin C and B vitamins, minerals like magnesium and calcium, and amino acids.
