IV Therapy and Vitamin Drips in London: Physician-Supervised Infusions From £195
Oral supplements lose 50-80% of their nutrients through digestion. IV therapy bypasses your gut entirely, delivering vitamins, minerals, and amino acids directly into your bloodstream for 100% bioavailability. It is not a replacement for a balanced diet — but when you need targeted nutrient support, faster recovery, or an energy boost that actually works, IV therapy delivers what oral supplements cannot.
The Online GP by The Wellness offers physician-supervised IV therapy at our Marylebone clinic from £195. Every treatment is overseen by a GMC-registered doctor, administered by registered nurses, and uses pharmaceutical-grade ingredients only.

Our IV Therapy Menu
Myers Cocktail — £295
The gold standard of IV therapy and our most popular formula. The Myers Cocktail was developed by Dr John Myers in the 1960s and remains the benchmark for comprehensive nutrient delivery. It combines high-dose vitamin C, B-complex vitamins, magnesium, calcium, and zinc in a single infusion. Ideal for general wellness, energy, and immune support. Treatment time is approximately 45 minutes.
Energy Support — £375
A high-dose B-vitamin formula designed for sustained energy. This is not a caffeine hit — it delivers methylcobalamin (the active form of B12), the full B-complex (B1, B2, B3, B5, B6), an amino acid blend including taurine and glutamine, and magnesium. Particularly beneficial if you have been running on empty, recovering from illness, or simply need to perform at your best. Treatment time is approximately 45 minutes.
Immunity Shield — £375
When your immune system needs reinforcement. This formula combines selenium, zinc, and high-dose vitamin C — the three nutrients with the strongest evidence base for immune function. Consider it before travel, during cold and flu season, when you feel the first signs of illness, or during periods of high stress that compromise your immune defences. Treatment time is approximately 45 minutes.
Hydration Plus — £395
Pure rehydration with clinical-grade isotonic saline and an electrolyte blend, enhanced with B-complex vitamins. This is the fastest way to correct dehydration — from travel, exercise, illness, or simply not drinking enough. One litre of IV fluid in 30-45 minutes delivers hydration that would take hours of drinking water to achieve.
Recovery Support — £405
Designed for post-exercise recovery, jet lag, or recovery from illness. Combines electrolytes, amino acids, antioxidants, vitamin C, and B-complex vitamins. Athletes, frequent travellers, and anyone recovering from physical exertion or dehydration benefit from this comprehensive recovery formula. Treatment time is approximately 45 minutes.
Beauty Glow — £425
A skin, hair, and nail formula built around glutathione (the body's master antioxidant), high-dose biotin, vitamin C, zinc, collagen-supporting compounds, and B-complex vitamins. Glutathione is poorly absorbed orally — IV delivery is significantly more effective. This formula complements topical skincare by working from the inside out. Treatment time is approximately 45 minutes.
NAD+ Therapy — £495
NAD+ (nicotinamide adenine dinucleotide) is a coenzyme found in every living cell, essential for cellular energy production, DNA repair, and metabolic function. NAD+ levels decline naturally with age — by your 40s, levels may have dropped by 50% compared to your 20s.
NAD+ IV therapy delivers this critical molecule directly into your bloodstream. Research in longevity science suggests NAD+ supplementation may support cognitive function, energy metabolism, cellular repair, and healthy ageing. It is popular among biohackers, executives, and anyone interested in proactive health optimisation.
NAD+ infusions take 45-90 minutes depending on dosage (250-500mg). Some patients experience a warm flushing sensation during infusion, which is normal and managed by adjusting the drip rate.

The Science: Why IV Beats Oral
When you take a vitamin tablet, it must survive your stomach acid, be absorbed through your intestinal wall, and pass through your liver before reaching your bloodstream. At each stage, nutrients are lost. Oral vitamin C absorption drops to around 50% at doses above 1,000mg. Oral B12 absorption averages just 1-5%.
IV therapy bypasses all of these limitations. One hundred per cent of the administered dose reaches your bloodstream directly. This does not mean oral supplements are worthless — they are important for daily baseline nutrition. But when you need therapeutic doses for specific goals, IV delivery is fundamentally more efficient.
This is why IV hydration works so rapidly. One litre of IV saline reaches your circulation within minutes, compared to hours for the same volume of water consumed orally. It is also why high-dose vitamin C and glutathione are most effective when delivered intravenously.
What to Expect
Before your treatment. A GMC-registered doctor conducts a brief medical consultation to review your health, current medications, and treatment goals. This ensures the treatment is safe and appropriate for you. If you have any allergies or contraindications, we will identify them before proceeding.
During your treatment. A registered nurse establishes IV access (a small cannula in your arm) and administers your chosen formula. You relax in a private treatment room — bring a book, your phone, or simply rest. Infusion time is typically 30-45 minutes, or 45-90 minutes for NAD+.
After your treatment. A brief monitoring period ensures you feel well before leaving. Many patients feel immediate hydration and energy benefits. Others notice effects building over 24-48 hours. There is no downtime — you can return to your normal activities immediately.
Who Benefits from IV Therapy?
Busy professionals who need consistent energy and cannot afford days of feeling sub-par. Executive performance demands mental sharpness, and nutrient deficiency quietly undermines it.
Frequent travellers dealing with jet lag, dehydration from flights, and the immune challenges of constant travel. A recovery drip after a long-haul flight gets you functioning hours faster than waiting for your body to rehydrate naturally.
Athletes and fitness enthusiasts seeking faster recovery after training. The combination of amino acids, electrolytes, and antioxidants supports muscle repair and reduces recovery time.
Anyone recovering from illness who needs an immune and energy boost. When you have been unwell, your body's nutrient stores are depleted — IV therapy replenishes them rapidly.
Pre-event preparation. Whether it is a wedding, a marathon, a business pitch, or a holiday — many patients book an IV drip in the days before an important event to ensure they look and feel their best.
International patients. Visitors to London who want to combat travel fatigue, adjust to the time zone, or simply optimise their health during their stay.

A Note on Expectations
We believe in honesty about what IV therapy can and cannot do. IV drips are a valuable tool for hydration, nutrient delivery, and recovery support. They are not a cure for serious illness, a substitute for a healthy diet, or a miracle treatment.
If you are experiencing persistent fatigue, chronic illness, or unexplained symptoms, IV therapy may help — but it may also be masking an underlying condition that needs proper investigation. Our doctors will always prioritise diagnosing the cause over treating the symptom. If blood tests or further investigation are warranted, we will recommend them.
This is the difference between a medical clinic that offers IV therapy and a wellness bar that sells drips. At The Online GP, your health comes first.
