How do vitamin drips work?
Vitamins taken orally are broken down in the stomach and digestive tract. In contrast, vitamins given intravenously are absorbed directly into the bloodstream. As a result, the rate of absorption of vitamins administered intravenously is 40% faster.
In short, IVs deliver higher concentrations of certain vitamins and minerals into the bloodstream faster and have a reputation among A-listers and Jet Sets as a quick (and expensive) hangover cure.
Vitamin delivery with intravenous therapy allows 99.9% of the vitamins to be absorbed, delivering them directly into the bloodstream for maximum effect, compared to 8% absorption with oral pills.
