A licensed medical professional will insert a small tube into your vein. The tube is attached to a bag containing the saline (basically salt water), as well as any other additives included in your package. Your formula will be pushed directly to your bloodstream for total bio-availability. This means you reap the full benefits of every vitamin and/or medication present in your IV bag almost immediately. IVs also replace lost fluids and electrolytes quickly and efficiently. Intravenous delivery is a fast way to re-hydrate and enjoy the effects of the nutrients included in our formulas.
