IV nutrient therapy delivers vitamins and minerals directly into the bloodstream. Here's what the clinical evidence actually supports, what to expect from a session, and the safety questions to ask before you book.

IV therapy has moved from hospital rooms into med spas and wellness studios with remarkable speed. "Drip bars" — some operating inside med spas, some as standalone businesses — now offer everything from hangover recovery to immune support to anti-aging protocols. Here's what's worth knowing before you book one.
IV therapy administers vitamins, minerals, electrolytes, and sometimes amino acids directly into a vein. This bypasses the digestive system entirely — oral supplements are partially degraded during absorption; IV delivery achieves nearly 100% bioavailability for water-soluble nutrients.
What this means in practice: you can achieve blood concentrations of certain vitamins (most notably vitamin C) via IV that would be impossible orally without causing GI distress.
What this doesn't mean: "high bioavailability" doesn't automatically translate to meaningful clinical benefit for healthy patients. The evidence base for IV nutrient therapy is strongest for specific medical conditions and weakest for general wellness in healthy populations.
Strong evidence:
Moderate evidence:
Weak or emerging evidence:
Being honest about the evidence isn't a reason not to try IV therapy if you're curious — it's a reason to calibrate expectations and choose a legitimate clinical provider over a hype-driven one.
Myers' Cocktail (the original) Created by Dr. John Myers in the 1970s. Typically contains: B vitamins (B1, B2, B5, B6, B12), vitamin C, magnesium, calcium. Used for fatigue, migraines, fibromyalgia, and general wellness.
High-dose Vitamin C 50–75g of vitamin C administered over 1–2 hours. Used as immune support and adjunct in integrative oncology. Requires G6PD screening before first session — G6PD deficiency can cause hemolysis with high-dose vitamin C.
NAD+ (Nicotinamide adenine dinucleotide) NAD+ is a coenzyme involved in cellular energy metabolism. IV administration is one way to raise cellular NAD+ levels quickly. Common protocols: 250–1,000mg over 2–4 hours. Often associated with brief flushing, chest tightness, and discomfort — typically transient.
Hydration / Electrolyte Normal saline or Lactated Ringer's with electrolytes. The most medically straightforward option.
Glutathione push Glutathione is the body's primary antioxidant. IV glutathione is absorbed into the bloodstream; whether it meaningfully raises intracellular levels is debated. Often added as a "push" at the end of a drip.
IV therapy is a medical procedure. A legitimate provider has:
Red flags:
IV therapy pricing ranges widely:
Add-ons (glutathione push, additional B12, zinc) typically run $25–$75 each.
Packages of 4–10 sessions are common at 15–25% savings. These make sense for established protocols (regular NAD+, monthly Myers') but not for first-time experimentation.
