What the evidence says. Graded none for wellness use: the one placebo-controlled Myers' cocktail trial was null, and trials of IV fluids for intoxication and exercise dehydration show no advantage over observation or drinking; real benefit is limited to diagnosed deficiency or malabsorption. (No Evidence evidence: No credible human evidence supports the marketed claims — widely considered ineffective.)
⚠
Health warning. For healthy people, IV vitamin drips offer no proven benefit over eating, drinking or oral supplements, and every infusion carries small but real risks of infection, vein injury, fluid overload and allergic reaction.
What is IV Vitamin Drips (Myers' Cocktail)?
IV Vitamin Drips (Myers' Cocktail) (Intravenous vitamin & mineral infusions) is a vitamin marketed for hangover relief. NutriDex grades the human evidence as No Evidence. IV vitamin drips deliver fluid plus vitamins and minerals directly into a vein; the classic 'Myers' cocktail' contains magnesium, calcium, B vitamins and vitamin C. They are sold by spas, 'IV bars' and mobile services for hangovers, energy, immunity, hydration and recovery. Intravenous vitamins are genuine medicine for specific problems such as severe malabsorption, Wernicke's encephalopathy or proven deficiency, but for healthy people the evidence is essentially absent. The only placebo-controlled trial of the Myers' cocktail (34 adults with fibromyalgia, 8 weekly infusions) found no significant difference from plain Ringer's solution on any outcome, because the placebo drip helped almost as much. In an emergency-department RCT of 144 intoxicated patients, a saline bolus did not speed sobering or discharge, and in dehydrated athletes IV fluids were no better than drinking. Infusions briefly raise blood vitamin levels, but the excess is excreted in urine. A 2025 JAMA Internal Medicine study found US regulation of IV spas is patchy and inconsistent.
Marketed Claims (unproven)
✕(Claimed) hangover relief
✕(Claimed) energy and immunity boost
✕(Claimed) faster hydration and recovery
✕(Proven, medical use only) treating diagnosed deficiency or malabsorption
Dosing & Compounds
Use & Legality
No evidence-based dose for wellness use; the classic modified Myers' cocktail is a slow push of magnesium (~0.4–1 g), calcium, B12 (1,000 µg), B6, B5, B-complex and vitamin C (~0.5–1 g), while IV bars typically add 250–1,000 mL of saline or Ringer's.
Active Compounds
Magnesium chloride and calcium gluconateB vitamins (B1, B5, B6, B12, B-complex)Vitamin C (ascorbic acid)Saline or lactated Ringer's fluid
Safety & Cautions
⚠
Any IV line carries risks of pain, bruising, phlebitis, infiltration and, especially with poor sterile technique or compounded bags, bloodstream infection; rapid fluid loads can cause fluid overload in people with heart or kidney disease. Fast magnesium can cause flushing, low blood pressure and slow heart rate; B vitamins such as thiamine rarely trigger allergic reactions; and high-dose vitamin C can cause oxalate kidney injury, haemolysis in G6PD deficiency and falsely high fingerstick glucose readings. After a woman died following a spa IV in 2023, Texas passed 'Jenifer's Law' (HB 3749, effective 1 September 2025), requiring a prescriber's order and licensed, supervised staff for elective IV therapy. WADA prohibits athletes from receiving IV infusions over 100 mL per 12 hours outside hospital care or clinical investigation.
