IV Vitamin Drips UK: Do They Work, and Are They Safe?
Quick answer
For healthy people there is little good evidence that IV vitamin drips improve energy, immunity, skin or recovery. The ASA has ruled clinics must not make health claims without adequate evidence in healthy humans, the NHS says most people get enough vitamins from a balanced diet, and drips risk infection and allergic reactions.
What do IV drip clinics claim?
Wellness IV drips put fluids, vitamins (often vitamin C and B vitamins), minerals such as magnesium, and sometimes glutathione or amino acids straight into a vein, usually over 30 to 60 minutes. Clinics and salons promote them for:
- more energy and less fatigue
- stronger immunity
- hangover relief and faster rehydration
- glowing skin, hair and nails, and skin lightening
- weight loss, better sleep and "anti-ageing"
- faster recovery after exercise
The selling point is "100% absorption" because the gut is bypassed.
What does the evidence show?
| Claim | Evidence grade | Best evidence |
|---|---|---|
| Correcting a diagnosed deficiency or dehydration (medical use) | Strong | Standard hospital practice under medical supervision |
| Energy, immunity, skin, sleep in healthy people | None | ASA ruling on Get A Drip, 2024 found claims unsupported |
| Fibromyalgia symptoms ("Myers' cocktail") | Early | Ali 2009 placebo-controlled pilot: no difference vs placebo |
| Skin lightening (glutathione) | None | Trading Standards warning, 2025 |
| Hangover cure | Early | No good trials of wellness drips |
"Better absorption" is not the same as "better health"
It is true that IV nutrients reach the blood directly. But the NHS says most people should get all the nutrients they need from a varied and balanced diet. If you are not deficient, your kidneys excrete much of the excess water-soluble vitamins within hours. Only a blood test and a clinician can tell you whether you need more of something, and if you do, tablets or prescribed injections are usually the right route.
The little research there is
The best-known controlled trial of the classic "Myers' cocktail" (magnesium, calcium, B vitamins and vitamin C) was a 2009 pilot in fibromyalgia. Both the drip and placebo groups improved, and there was no statistically significant difference between them. The authors called efficacy "as yet uncertain". There are no good trials showing wellness drips help healthy people's energy, immunity or skin.
What do UK regulators say?
- ASA (Advertising Standards Authority): In February 2024 the ASA placed IV drip provider Get A Drip on its non-compliant advertisers list after it made claims about energy, immunity, removing toxins, skin, anti-ageing, metabolism, weight loss and sleep. The ASA said providers must not make any health-benefit claims unless they hold adequate evidence of IV drips in normally healthy humans.
- MHRA (medicines regulator): According to the Anaphylaxis Campaign, the MHRA says an IV product is not automatically a medicine just because of how it is given, so many wellness products fall under general product safety rules. The MHRA acts when clinics make medicinal claims, and adverse reactions can be reported through its Yellow Card scheme.
- CQC (care regulator): ITV reported that since 2022 the CQC has said providers of intravenous therapy must register with it, but doctors warn drips are still offered in salons by staff who may not be medically trained.
- Trading Standards: In June 2025 the Chartered Trading Standards Institute issued a public warning about glutathione skin-lightening drips, offered by over 300 salons, with reported anaphylaxis, kidney strain and infections. It said these procedures remain largely unregulated, and advised avoiding IV drips outside a regulated medical setting.
Drip, tablet or food: how do they compare?
| Route | Cost | Who it suits | Main risks |
|---|---|---|---|
| Balanced diet | Part of normal shopping | Almost everyone, per the NHS | Very low |
| Tablets or capsules | A few pounds a month | People with a known gap (for example vitamin D in winter) or advised by a GP | Taking too much over time; interactions |
| Prescribed injection (for example B12) | NHS or private | Diagnosed deficiency or poor absorption | Injection-site reactions |
| Wellness IV drip | Typically tens to hundreds of pounds per session | No proven group of healthy people | Infection, vein damage, allergy, fluid overload |
What actually happens at a drip appointment?
A good clinic should take a medical history, check for allergies and medicines, and ideally ask for recent blood results. A nurse or doctor inserts a cannula (a thin plastic tube) into a vein, usually in the arm, and the bag runs in over 30 to 60 minutes. You should be monitored throughout and told what to do if you feel unwell afterwards. If a salon skips the history, cannot tell you who prescribed the product, or will not name the exact ingredients and doses, walk away.
Who should be careful?
- Anyone with kidney, heart or liver disease: extra fluid and minerals can be dangerous.
- People with allergies: reactions, including anaphylaxis, can happen; the Anaphylaxis Campaign urges a full medical history first.
- People on medicines: high-dose vitamins and minerals can interact with some drugs; check with a pharmacist.
- Pregnant or breastfeeding women, and anyone with G6PD deficiency (an inherited enzyme condition) before high-dose vitamin C.
- Everyone: any cannula carries a risk of infection, bruising, vein inflammation and, rarely, air entering the vein.
If you still want one: what to look for
- A doctor or nurse-led clinic registered with the CQC (England), with a prescriber who reviews your history.
- A recent blood test or clear clinical reason for what is being given.
- Licensed products with clear ingredient lists and doses; avoid glutathione for skin lightening.
- No promises of immunity, weight loss, anti-ageing or toxin removal.
- A plan for emergencies, including anaphylaxis treatment on site.
Why do some people feel better after a drip?
Some people do feel brighter afterwards. Possible reasons include simple rehydration if they were dehydrated, resting for an hour, the expectation of feeling better (placebo), and, in a minority, correcting a real but undiagnosed deficiency. Only the last one needs a vitamin infusion, and it is better found with a blood test so the cause can be treated properly. In the Myers' cocktail trial, people given a placebo drip improved too, which shows how strong expectation can be.
Bottom line
IV drips are essential medicine when there is a medical need. For healthy people they are an expensive, invasive way to get nutrients most of us already get from food, with no good evidence of benefit and small but real risks. If you feel tired all the time, see your GP for a blood test rather than booking a drip. If you do book one, choose a CQC-registered, clinician-led service, ask exactly what is in the bag and why, and ignore any promise of immunity, weight loss or anti-ageing.
Frequently asked questions
Do IV vitamin drips actually work?
+
For healthy people, there is little good evidence. The ASA ruled in 2024 that a UK provider's claims about energy, immunity, skin, metabolism and sleep were not backed by adequate evidence in healthy humans. A placebo-controlled pilot of the Myers' cocktail found no significant difference from placebo. Drips are valuable for people with diagnosed deficiencies or dehydration under medical care.
Are IV drips safe?
+
They carry real, if usually small, risks: infection, bruising, vein inflammation, allergic reactions including anaphylaxis, and fluid or mineral problems in people with kidney or heart disease. Trading Standards has warned about salons offering drips without medical supervision. If you go ahead, use a CQC-registered clinic led by a doctor or nurse.
Are IV drips regulated in the UK?
+
Only partly. The CQC says providers of IV therapy must register, the ASA polices advertising claims, and the MHRA acts on medicinal claims and runs the Yellow Card reporting scheme. However, many wellness products fall under general product rules, and Trading Standards says salon drips remain largely unregulated.
Do IV drips cure hangovers?
+
There is no good evidence that wellness drips work better than drinking water, eating and resting. Fluids can ease dehydration, but you can usually rehydrate by mouth. Get medical help if you cannot keep fluids down, or symptoms are severe or unusual.
Are glutathione skin lightening drips legal?
+
Glutathione is not licensed for cosmetic skin lightening in the UK. Trading Standards issued a public warning in 2025 after finding over 300 salons offering these drips, with reports of anaphylaxis, kidney strain and infections. Campaigners say prescribing it without a genuine clinical need is illegal. Avoid them.
Should I get an IV drip if I feel tired all the time?
+
See your GP first. Ongoing tiredness can have many causes, such as anaemia, thyroid problems, poor sleep or depression, which need proper diagnosis. A blood test can show whether you are low in iron, vitamin B12, vitamin D or folate, and the GP can advise on treatment if you are.
