Since IV therapy provides liquids directly into the bloodstream, it can supplement vitamins and nutrients while entirely skipping the digestive tract. If the body absorbs the fluids through an IV, they are absorbed more comprehensively, providing a more significant benefit than other comparable ways to boost wellness. A handful of ailments that may be treated with IV therapy include fatigue, feeling bad after a night of drinking, dehydration, vitamin deficiencies, arthritis, recurring pain, migraines, and brain fog.
