IV therapy is not a one-size-fits-all treatment. The right infusion formula depends on your specific health goals, deficiencies, and lifestyle — and choosing the correct protocol makes all the difference between a modest improvement and a transformative result.
At Neo Clinics in Girona, every IV therapy session is individualised. But to help you understand your options before your consultation, this guide explains the most important IV infusion types, what each one does, and who benefits most from each protocol.
Why the Type of IV Infusion Matters
All IV therapy shares the same fundamental mechanism: delivering compounds directly into the bloodstream for complete, immediate absorption. But the specific nutrients, antioxidants, and therapeutic agents in each formula determine what effect the treatment has on your body.
A general hydration drip and a high-dose NAD+ infusion are both IV therapies — but they work on entirely different systems and produce entirely different outcomes. Understanding which formula targets your specific needs is the first step to getting the most out of treatment.
The Most Important IV Therapy Protocols
1. High-Dose Vitamin C Infusion — For Immunity and Inflammation
Vitamin C is one of the most researched and clinically validated IV therapies available. At the concentrations delivered intravenously — many times higher than can be achieved orally — vitamin C acts as a potent antioxidant, anti-inflammatory agent, and immune system activator.
Best for:
- Frequent illness and low immune resilience
- Recovery after infection or post-viral fatigue
- Chronic inflammation
- Oxidative stress and cellular damage
- Adjunctive support for cancer treatment (under medical supervision)
High-dose IV vitamin C consistently outperforms oral supplementation because vitamin C is rapidly excreted by the kidneys at high oral doses, making it impossible to reach therapeutic blood levels through tablets or capsules alone. IV delivery bypasses this limitation entirely.
2. Myers Cocktail — The All-Round Wellness Formula
The Myers cocktail is the most widely used IV infusion formula in the world and remains a cornerstone of integrative medicine. Developed by Dr. John Myers in the 1970s, it contains a precisely balanced combination of magnesium, B vitamins (B1, B2, B3, B5, B6, B12), vitamin C, and calcium.
Best for:
- General fatigue and low energy
- Chronic migraines and tension headaches
- Upper respiratory tract infections
- Seasonal allergies
- Fibromyalgia and muscle pain
- Stress recovery and burnout
The Myers cocktail is the ideal starting point for patients new to IV therapy, delivering broad-spectrum nutritional support that most people feel almost immediately.
3. NAD+ Infusion — The Longevity and Brain Optimisation Formula
NAD+ (nicotinamide adenine dinucleotide) is one of the most important molecules in the human body. It is essential to cellular energy production, DNA repair, and the function of proteins called sirtuins that regulate aging at the cellular level. Unfortunately, NAD+ levels decline by up to 50% between the ages of 40 and 60 — a decline now recognised as a major driver of aging, cognitive decline, and metabolic dysfunction.
IV NAD+ infusions replenish these levels directly, producing effects that cannot be replicated by any oral supplement currently available.
Best for:
- Cognitive decline, brain fog, and memory difficulties
- Fatigue and mitochondrial dysfunction
- Anti-aging and longevity optimisation
- Addiction recovery support
- Mood disorders and mental health support
- Athletes seeking performance and recovery enhancement
NAD+ infusions are typically longer sessions — around 2–4 hours — as they need to be administered slowly. Many patients describe the experience as profoundly restorative, with notable improvements in mental clarity and energy sustained for weeks after treatment.
4. Glutathione Infusion — The Master Antioxidant
Glutathione is the body’s primary endogenous antioxidant — a tripeptide produced in the liver that neutralises free radicals, supports liver detoxification, modulates immune function, and protects cells from oxidative damage. Oral glutathione is poorly absorbed; IV delivery ensures complete availability at therapeutic concentrations.
Best for:
- Liver support and detoxification
- Skin health, brightness, and anti-aging
- Autoimmune conditions and immune modulation
- Neurological protection and cognitive support
- Post-illness recovery and cellular repair
Glutathione is frequently administered at the end of other IV therapy sessions as a powerful complement to high-dose vitamin C or Myers cocktail protocols.
5. Hydration and Electrolyte Infusion — For Performance and Recovery
Simple but profoundly effective, IV hydration and electrolyte replenishment delivers saline solution enriched with essential electrolytes — sodium, potassium, magnesium, and calcium — directly into the bloodstream. This restores cellular hydration and electrolyte balance far more rapidly and completely than oral rehydration.
Best for:
- Athletic recovery after intense training or competition
- Recovery from illness involving vomiting, diarrhoea, or fever
- Jet lag and travel fatigue
- Hangover recovery
- Pre-event preparation for athletes and performers
6. Immune Boost Infusion — For Active Illness and Prevention
This targeted formula combines high-dose vitamin C with zinc, selenium, B vitamins, and immune-supporting amino acids to provide comprehensive support for the immune system — both during active illness and as a preventive measure during high-risk periods such as winter or periods of intense stress.
Best for:
- Actively fighting a cold, flu, or respiratory infection
- Preventive immune support during winter months
- Recovery from illness
- Immunocompromised patients (under medical supervision)
How to Know Which IV Therapy Formula Is Right for You
The most effective approach is always a personalised one. At Neo Clinics, your IV therapy protocol is determined by:
- A comprehensive health and symptom assessment
- Blood testing and biomarker analysis where indicated
- Your specific health goals and priorities
- Your response to previous sessions
During your initial consultation, our medical team will review your history, identify your key deficiencies and health priorities, and recommend the protocol — or combination of protocols — most likely to produce the results you are looking for.
Many patients benefit most from a sequential programme — beginning with a foundational formula such as the Myers cocktail and progressing to more targeted protocols such as NAD+ or glutathione as their health picture becomes clearer.
