IV Vitamin Drips: What The Evidence Actually Says
16 July 2026
The IV drip bar is wellness at its most cinematic: a recliner, a cannula, a bag of vitamins straight into the vein. "Fill your energy up," says the poster. The evidence says something quieter.
The pitch
Drip menus offer energy blends, immunity boosts, skin brighteners and hangover rescues, typically £100 to £250 a session. The logic sounds airtight: skip the gut, get 100% absorption, feel amazing.
The problem with the logic
Absorption was never the bottleneck. If you're a broadly healthy person eating reasonably, your gut absorbs the vitamins you need and your body uses what it can. Flood the bloodstream with more and it doesn't bank the surplus — water-soluble vitamins like C and the Bs are filtered out by your kidneys within hours. The industry joke is old because it's accurate: it's the most expensive urine in town.
Trials of IV vitamin therapy in healthy people are thin, small, and consistently underwhelming — the well-known "Myers cocktail" studies showed effects that largely matched placebo. The strong feeling of a good drip is real, but a litre of IV fluid will do that on its own, especially if you arrived dehydrated or hungover. You paid for vitamins; the water did the work.
Where drips genuinely matter
None of this makes IV nutrition fake — hospitals use it daily, for people who can't eat, can't absorb (severe gut conditions), or have proven deficiencies needing rapid correction. That's medicine, prescribed and monitored. The recliner version borrows its credibility while skipping its criteria.
The risk column isn't empty either
Any cannula carries small risks of infection, vein irritation and bruising, and "more" isn't harmless — high-dose IV vitamin C, for instance, can cause kidney stones in susceptible people. Small risks, but you're taking them for benefits the evidence can't find.
- Tired all the time? The useful checklist is here, and it starts with sleep and bloods, not a drip.
- Suspect a deficiency? A GP blood test costs nothing and answers the question a menu can't.
- Want the drip-bar glow? A litre of water is 0.1% of the price.
