IV vitamin infusions have become a fixture on the London wellness circuit, and the market covers every claim from hangover recovery to skin quality to immune support. Some of those claims are reasonable. Others sit well ahead of the evidence. Below is how we think about IV drips at the clinic, which ones we offer, which ones we do not, and how to choose between them.
For most patients at the clinic, the sensible starting point is a general replenishment drip covering hydration, electrolytes and the key vitamins most Londoners run marginally low on. For patients with documented iron deficiency, the Iron Clinic is a separate and more specialist service.
An IV drip delivers fluid, electrolytes and a defined dose of vitamins directly into the bloodstream over 30 to 60 minutes. The main advantage over taking supplements orally is that it bypasses the digestive system, which can limit how much your body absorbs. In practice, how much difference that makes depends on the individual and the specific vitamin. For hydration and electrolyte correction after a demanding week, an IV does what it says. For broader wellness claims, the evidence is thinner.
The most common ingredients are saline fluid, B vitamins, vitamin C, magnesium, calcium and sometimes glutathione. The menu differs between providers. What matters is that the drip is medically prescribed and given in a proper clinical setting by a trained practitioner. An IV procedure carries small but real risks of infection, bruising at the needle site and allergic reaction, and should not be treated as a casual wellness top-up.
Sensible candidates include patients recovering from a physically demanding week, patients with documented low iron or B12 who struggle with oral supplements, patients preparing for a major physical event, and patients running low on vitamin D through the winter. IV drips can also complement a skin quality plan alongside Profhilo or Julaine, though they are not a replacement for injectable or device work.
IV drips are not appropriate during pregnancy without specific medical input, in patients with vein or circulation problems without review, in patients with kidney or heart conditions without specialist clearance, or for healthy adults with no meaningful deficiency. The idea that more vitamins is always better is not supported by evidence. Some vitamins simply pass through the body unused, and some can build up to problematic levels.
See our list of Iv drips and when each one is appropriate to use in the table on the side.
We do not offer NAD+, ozone, peroxide or chelation infusions. The evidence base does not support their use for general wellness, and some carry safety concerns we are not willing to overlook. If you have heard about any of these elsewhere and want a considered conversation, Dr Brennand is happy to explain our position at consultation.
| Drip | What it covers | Who it suits |
|---|---|---|
General replenishment | Hydration, electrolytes, B vitamins and vitamin C. Around 45 minutes per session. | Patients wanting a general top-up rather than targeting a specific deficiency. |
Iron infusion (Iron Clinic) | Specialist iron infusion, confirmed by blood test with full medical oversight. Not a menu drip. | Patients with documented iron deficiency only. Referred through the Iron Clinic. |
Hydration and electrolyte effects are immediate and typically last 24 to 48 hours after a replenishment drip. Vitamin effects depend on where you are starting from. A patient who was genuinely low in a particular vitamin will often notice a difference over the following week or two. A patient who was already well-nourished will often notice very little. This is the opposite of how IV drips are usually marketed, and it is worth being clear about: if your levels are already good, the benefit will be small.
For iron infusions, improvements in energy and mental clarity can take two to four weeks to appear, and the benefit lasts many months depending on the dose and the cause of the deficiency.
“The honest recommendation is that IV drips are a sensible tool in specific circumstances and a questionable tool in general. For a patient recovering from a demanding week, or with a documented deficiency, or preparing for a specific event, they have a role. For routine monthly use by a healthy adult with no particular need, the evidence does not support the claims. We prescribe them when they are genuinely useful and decline when they are not.”

IV drips at the clinic are prescribed and reviewed by Dr Brennand. The cannula and infusion are delivered by our trained clinical team under his lead. All infusions take place in a properly clinical room.
IV drips are a useful tool in the right circumstances, and an oversold one in the wrong ones. At L’Atelier Aesthetics we prescribe them when the evidence supports it, for recovery, documented deficiencies and specific preparation, and we are straightforward when they are not the right choice. If you would like to discuss whether an IV drip makes sense for you, Dr Brennand will give you an honest answer at consultation. Our clinic is at 101 Harley Street, London W1G 6AH, within easy walking distance of Bond Street, Oxford Circus and Regent’s Park. Book through the website or call us to arrange a time.
For most patients, the general IV replenishment drip covering hydration, electrolytes and key vitamins is the right starting point. For documented iron deficiency, we refer patients to our Iron Clinic, which is a separate specialist service.
A standard replenishment drip takes around 45 minutes. Iron infusions typically take 60 to 90 minutes. Patients can read or work during the session.
IV drips are prescribed by Dr Brennand and administered by trained clinical staff. They carry small but real risks of infection, bruising at the needle site and allergic reaction, which are discussed at consultation. We decline to treat where the risk does not justify the benefit.
They work for defined purposes: hydration, electrolyte correction and addressing documented deficiencies. They do not have strong evidence for general wellness claims in otherwise healthy adults. We are happy to discuss that openly at consultation.
No. IV drips are not given during pregnancy without specific medical input. Iron infusions in pregnancy, where needed, are typically arranged through an antenatal service.
We recommend IV drips when there is a specific reason, such as recovery, a documented deficiency or preparation for an event. Routine monthly infusions for most healthy adults are not necessary and are not a good use of money. Dr Brennand will give a straightforward answer at consultation.
