IV therapy is used to promote health and wellness. The infusion of fluids, vitamins and minerals can help support a healthy immune system, promote healthy skin and keep you hydrated. The right balance of vitamins and minerals in the body can also help improve your energy levels. IV therapy drips amino acids, vitamins, minerals and fluids at a controlled rate. Once you are connected to the IV, which is usually a quick and simple process, the duration of the therapy will depend on why you are undergoing IV therapy. This process can take longer, but will typically require 45 minutes to an hour of your time.
