IV Therapy
IV Therapy: What the Evidence Actually Supports
IV nutrient therapy is popular — and often oversold. A physician's take on when it helps, when it doesn't, and what to look for.

Where IV therapy genuinely shines
- Repletion after documented deficiencies (iron, B12, magnesium)
- Recovery after intense athletic or surgical stress
- Hydration support during acute illness
- Adjunctive therapy for migraine, fibromyalgia, and select autoimmune conditions
Where the claims outpace the evidence
"Immunity boosts" for healthy adults, generic "detox" drips, and heroic-dose vitamin C outside oncology settings are largely marketing.
What to look for in a clinic
A physician on-site, transparent formulations, sterile compounding, and a real intake — not a menu.
