Favoured by the likes of Simon Cowell, Rita Ora, Cheryl Cole and now Kelly Osbourne, a cocktail of health promoting and energy boosting vitamins is either injected into the patient's bum, or you can have an infusion drip into the arm.
Rihanna, Katy Perry and Lady Gaga have all sworn of their benefits for keeping healthy on tour, meanwhile Cowell told GQ, "Even when I'm having a viewing session with producers, [a nurse] just sticks the needle in me and we carry on whatever we are doing."
Even though it is popular with our wheatgrass drinking friends across the pond, you can get the treatment here in the UK.
EF MediSpa in London offers five different types of boosters that range from stress busting, energy busting to promoting weight loss. They're also supposed to be good after excessive partying.
Jumping on the celebrity health bandwagon is never cheap, with a vitamin shot setting you back £250. But we've all had those hangovers where we would give someone our own arm if it meant the head drilling stopped.
Despite their popularity, medical experts aren't convinced that these injections actually work, much like the vitamin supplement before them. In fact, there is no scientific or clinical research to suggest that a vitamin boost is actually beneficial or effective at curing exhaustion.
Some psychiatrists believe it's the placebo effect - where someone feels better because they think the vitamins should make them feel better.
We're intrigued either way. If it wasn't for our crippling fear of needles and spending money, we'd be all over this.
