If you’ve been feeling exhausted, run down, or simply not performing at your best, you may have heard about IV therapy — and wondered whether it could help you.
The short answer is: for many people, it absolutely can.
At Neo Clinics in Girona, Spain, IV therapy is one of our most popular treatments, used by patients dealing with chronic fatigue, weakened immunity, brain fog, inflammation, and a wide range of other health concerns. This guide explains exactly what IV therapy is, how it works, what it can treat, and what you can expect from a session at our clinic.
What Is IV Therapy?
IV therapy — short for intravenous therapy — is the direct delivery of vitamins, minerals, amino acids, antioxidants, and other therapeutic compounds into the bloodstream through an intravenous drip. Because the infusion bypasses the digestive system entirely, the nutrients are absorbed at near 100% bioavailability — a level that is simply not achievable through oral supplementation.
When you take vitamins or supplements by mouth, your digestive system absorbs only a fraction of the active compounds — typically between 20% and 50%, and sometimes far less, depending on your gut health, metabolism, and the specific nutrient involved. IV therapy sidesteps this limitation entirely, flooding your cells with exactly what they need at therapeutic concentrations.
The result is an effect that is faster, more powerful, and more consistent than anything oral supplements can provide.
How Does IV Therapy Work?
An IV therapy session at Neo Clinics is straightforward and comfortable:
1. You arrive at the clinic and are welcomed by our medical team
2. A clinician performs a brief health assessment and reviews your goals
3. A small catheter is inserted into a vein — typically in the arm
4. Your customised infusion is administered slowly over 30–90 minutes, depending on the formula
5. You relax comfortably throughout — reading, listening to music, or simply resting
6. You leave the clinic feeling refreshed, with no recovery time required
The entire experience is medically supervised from start to finish. Every infusion at Neo Clinics is individually compounded based on your health profile, goals, and any blood or biomarker results we have on file.
What Does IV Therapy Treat?
The range of conditions and goals that IV therapy can support is broad. At Neo Clinics, our infusion protocols are designed to address:
Chronic Fatigue and Low Energy
One of the most common reasons patients seek IV therapy is persistent fatigue that does not resolve with rest. Whether the cause is nutritional depletion, mitochondrial dysfunction, chronic stress, or post-viral illness, high-dose IV nutrients — particularly magnesium, B vitamins, and vitamin C — can restore cellular energy production rapidly and effectively.
Immune System Support
High-dose vitamin C infusions are among the most well-researched IV therapies for immune support. At the concentrations achievable through IV delivery, vitamin C functions as a powerful antioxidant and immune modulator — reducing the severity and duration of illness and supporting long-term immune resilience.
Brain Fog and Cognitive Decline
Nutrient deficiencies — particularly B12, magnesium, and certain amino acids — are a major but underrecognised driver of cognitive symptoms including poor concentration, memory difficulties, and mental fatigue. IV delivery of these nutrients supports neurological function and often produces rapid improvements in mental clarity.
Inflammation and Oxidative Stress
Chronic low-grade inflammation is now recognised as the underlying driver of a wide range of conditions including metabolic syndrome, autoimmune disorders, cardiovascular disease, and accelerated aging. Antioxidant-rich IV formulas — including glutathione, vitamin C, and alpha-lipoic acid — directly combat oxidative stress and reduce systemic inflammation.
Athletic Performance and Recovery
Elite athletes and serious fitness enthusiasts use IV therapy to accelerate post-training recovery, replenish minerals lost through sweat, reduce muscle soreness and inflammation, and maintain peak performance during periods of intense training. IV hydration and electrolyte replenishment is significantly more effective and efficient than oral rehydration alone.
Anti-Aging and Longevity
NAD+ (nicotinamide adenine dinucleotide) IV therapy has emerged as one of the most exciting developments in longevity medicine. NAD+ is a coenzyme essential to cellular energy metabolism and DNA repair, and its levels decline significantly with age. IV NAD+ infusions replenish these levels, supporting mitochondrial function, cognitive performance, and overall cellular health in ways that oral supplementation cannot replicate.
Skin Health
Glutathione — the body’s master antioxidant — delivered intravenously supports skin brightness, collagen production, and protection against oxidative damage. Many patients report visible improvements in skin tone and texture after a course of glutathione infusions.
Post-Surgery Recovery
IV therapy can significantly accelerate the healing process following surgery by delivering the high concentrations of vitamin C, zinc, and amino acids needed for tissue repair directly to the cells that need them most.
Is IV Therapy Safe?
Yes. IV therapy is a well-established medical procedure that has been used in clinical settings for decades. When performed by a qualified medical team — as it always is at Neo Clinics — it carries an excellent safety profile.
The most common side effect is mild discomfort or bruising at the insertion site, which resolves quickly. Allergic reactions to infusion components are possible but rare, and our team monitors every patient throughout their session to respond immediately if needed.
Before beginning any IV therapy programme, our clinical team conducts a thorough health assessment to identify any contraindications and to ensure your infusion formula is appropriate for your individual needs.
How Long Does an IV Therapy Session Take?
Session duration varies depending on the infusion formula, typically ranging from 30 minutes to 90 minutes. Most patients find the sessions genuinely relaxing — a quiet hour away from the demands of daily life while their body replenishes at the cellular level.
How Many Sessions Are Needed?
This depends on your goals and your starting health status. Some patients experience meaningful improvements after a single session — particularly for acute fatigue or recovery after illness. For chronic conditions or long-term wellness goals, a course of sessions — typically four to eight over four to eight weeks — is recommended to achieve lasting results.
Our team will advise you on the optimal frequency based on your individual assessment and your response to initial treatment.
