IV vitamin therapy delivers nutrients directly into your bloodstream, bypassing digestive absorption barriers to achieve 100% bioavailability compared to 20-50% from oral supplements, with patients typically experiencing noticeable energy improvements within 24-48 hours of treatment. At The Wellness in Marylebone, our GMC-registered physicians administer customised IV infusions tailored to your specific health needs.

Whether you're battling fatigue, recovering from illness, preparing for a demanding period, or simply optimising your wellness, IV therapy offers a direct route to nutrient replenishment that oral supplements cannot match.

What is IV Vitamin Therapy?

IV (intravenous) vitamin therapy involves administering vitamins, minerals, and other nutrients directly into your bloodstream through a small needle inserted into a vein, typically in your arm.

This method bypasses the digestive system entirely. When you take oral supplements, they must pass through your stomach and intestines, where absorption is limited and variable. Factors like gut health, food interactions, and individual metabolism significantly affect how much actually reaches your cells.

Absorption comparison:

Delivery MethodTypical Absorption RateOral tablets10-20%Oral liquids20-30%Sublingual30-50%Intramuscular injection80-90%IV infusion100%

With IV delivery, 100% of the nutrients enter your bloodstream immediately, available for your cells to use.

Who Benefits from IV Vitamin Therapy?

Busy Professionals and Executives

High-stress careers deplete nutrients rapidly. B vitamins, magnesium, and vitamin C are particularly affected by stress. IV therapy provides rapid replenishment that supports sustained energy, mental clarity, and resilience.

Frequent Travellers

Jet lag, altitude exposure, recycled cabin air, and disrupted sleep patterns tax the body significantly. Pre-flight infusions can boost immunity, while post-travel sessions accelerate recovery and reduce jet lag duration.

Athletes and Fitness Enthusiasts

Intense training increases nutrient demands. IV therapy can support recovery, reduce muscle fatigue, and optimise performance. Many professional athletes use IV therapy as part of their regimen.

Those with Digestive Issues

Conditions affecting nutrient absorption (IBS, Crohn's, celiac, post-bariatric surgery) make oral supplementation ineffective. IV delivery bypasses digestive limitations entirely.

Recovery from Illness

After viral infections, food poisoning, or periods of poor nutrition, IV therapy accelerates recovery by rapidly restoring depleted nutrients.

General Wellness Optimisation

Even without specific deficiencies or conditions, IV therapy can enhance overall vitality, skin health, immunity, and wellbeing. Many patients incorporate regular infusions into their wellness routine.

Hangover Recovery

Alcohol depletes B vitamins and causes dehydration. IV therapy rapidly reverses these effects, providing relief from hangover symptoms within hours rather than days.

The IV Therapy Experience at The Wellness

Step 1: Consultation

Before your first infusion, you'll have a brief consultation with our medical team. We discuss your health history, current concerns, goals, and any contraindications. For comprehensive optimisation, we may recommend blood testing to identify specific deficiencies.

Step 2: Comfortable Setup

You'll relax in our comfortable treatment chairs. Our nurse or doctor inserts a small cannula into a vein in your arm or hand. Most patients describe this as a brief pinch, no worse than a standard blood test.

Step 3: Infusion (30-60 minutes)

The infusion flows slowly into your bloodstream. During this time, you can relax, read, work on your laptop, or simply rest. Many patients find the experience surprisingly pleasant.

Step 4: Immediate Aftercare

Once complete, we remove the cannula and apply a small plaster. You can return to normal activities immediately. Most patients notice effects within hours, with full benefits developing over 24-48 hours.

What you might feel during infusion:

• Warmth spreading through the body

• A vitamin taste in the mouth (common with B vitamins)

• Sense of relaxation

• Energy increase (sometimes during the session itself)

Why our pricing:

Is IV Vitamin Therapy Safe?

IV therapy is extremely safe when administered by qualified medical professionals using proper protocols.

Safety considerations we follow:

• Full medical screening before treatment

• GMC-registered doctors and trained nurses

• Pharmaceutical-grade nutrients only

• Sterile technique and single-use equipment

• Appropriate infusion rates to prevent adverse reactions

• Monitoring throughout treatment

Possible side effects (rare and typically mild):

• Bruising at injection site

• Temporary cooling sensation

• Vitamin taste in mouth

• Very rarely: vein irritation

Who should avoid IV therapy:

• Those with kidney disease (certain formulations)

• Those with certain heart conditions (fluid considerations)

• Pregnant women (as precaution)

• Those with allergies to specific nutrients

We screen for contraindications during your consultation.

IV Therapy vs Oral Supplements

When IV therapy is superior:

• You need rapid results (can't wait weeks for oral supplements to build up)

• You have digestive absorption issues

• You need high doses that would cause GI upset orally

• You're severely depleted and need fast restoration

• You want guaranteed, consistent absorption

When oral supplements may suffice:

• Maintenance of already-adequate levels

• Budget is a primary concern

• You have excellent digestive health

• You're not seeking rapid results

• Daily convenience is priority

Many patients combine both: IV therapy for periodic boosts and rapid correction, oral supplements for daily maintenance.

How Often Should You Get IV Therapy?

Frequency recommendations:

GoalRecommended FrequencyAcute recovery (illness, hangover)Single treatment as neededGeneral wellness maintenanceMonthlyHigh-stress periodsWeekly to bi-weeklyAthletic performanceWeekly during trainingChronic fatigue or deficiencyWeekly initially, then monthlyPre-travel immune boost1-3 days before departure

How quickly will I feel the effects?

Many patients notice effects during or immediately after the infusion. Maximum benefits typically develop over 24-48 hours as nutrients distribute throughout your system.

The needle insertion feels like a brief pinch, similar to a blood test. Once the cannula is in place, there's no pain during the infusion. Most patients find the experience comfortable.

How long does each session take?

Most infusions take 30-60 minutes. Budget extra time for your first visit to allow for consultation and setup.
