IV Therapy: What It Actually Does (And What's Overhyped)

IV Therapy: The Honest Guide

IV therapy — delivering vitamins, minerals, and hydration directly into your bloodstream — has exploded from hospital settings into wellness spas and mobile van services. Celebrities swear by it. Skeptics call it expensive urine. The truth, as with most wellness trends, is somewhere in the middle.

What IV Therapy Actually Does Well

• Rapid rehydration: One liter of IV saline rehydrates faster and more completely than drinking water, since it bypasses digestion entirely. For severe hangovers, illness recovery, or post-athletic performance — this benefit is real and well-supported.
• B12 and magnesium deficiency: People who are genuinely deficient in B12 (common in vegans, older adults) or magnesium see real benefits from IV delivery vs. oral supplements that have lower absorption rates.
• High-dose Vitamin C: At doses of 15–25g, IV vitamin C has shown legitimate benefits in some clinical contexts including immune support and certain cancer adjunct therapies. Oral vitamin C cannot reach these blood levels without severe GI distress.
• Migraine relief: IV magnesium sulfate is a legitimate medical treatment for migraines, used in ERs. Wellness IV therapy with magnesium can provide similar relief.

What's Mostly Hype

• Routine vitamin drips for healthy people: If you're not deficient in a nutrient, adding more via IV doesn't boost performance — your kidneys simply excrete the excess. "Energy boost" from B vitamins in people who aren't deficient is largely placebo.
• Anti-aging or "glow" drips: Glutathione drips are marketed for skin brightening. The evidence is weak for topical aesthetic effect from IV glutathione.
• Immunity boosting for healthy people: Vitamin C IV in healthy, non-deficient individuals has not been shown to meaningfully reduce illness frequency.
