Intravenous or IV vitamin therapy is a process of injecting beneficial vitamins and minerals such as magnesium directly into the bloodstream so that they can be used to benefit overall health and the immune system.
The process is more effective at delivering vitamins to the body, compared with eating food or even taking supplements, as it can bypass various biological processes, most notably the process of digestion. It also allows for a higher concentration of nutrients to be administered to the body compared with what could be achieved by eating a meal. But of course, this form of therapy is no substitute for a healthy diet.
