Best IV Therapy Clinics in Spain: NAD+, Myers Cocktail, Glutathione & More

Types of IV therapy available in Spain

Spanish longevity clinics offer a wide range of intravenous therapies, each targeting different health goals. Here are the most popular options:

Why Spain for IV therapy?

Spain has emerged as a top destination for IV vitamin therapy thanks to several key advantages. Treatment costs are significantly lower than in the US or UK — a Myers Cocktail that costs $250–400 in New York runs €100–200 in Madrid or Barcelona. All IV therapy in Spain must be administered by qualified medical professionals, as required by Spanish healthcare law, providing an additional layer of safety compared to less-regulated markets.

The country's growing wellness tourism infrastructure means many clinics cater to international clients with bilingual staff, modern facilities and convenient booking systems. Combined with Spain's climate, lifestyle and food culture, it's an ideal destination to combine IV therapy with a broader health optimisation experience.

How we evaluate IV therapy clinics

Not all IV therapy providers meet the same standards. At LongevityMap, we assess clinics on four critical quality criteria:

• Pharmaceutical-grade ingredients — GMP-certified suppliers with full traceability on every batch.
• Laminar flow hood preparation — IV bags mixed in sterile conditions to prevent contamination.
• Medical supervision during infusion — A qualified nurse or doctor present throughout the session to monitor vital signs and adjust flow rates.
• Proper dosing protocols — Evidence-based formulations with documented dosing rationales, not one-size-fits-all drips.

Safety considerations

IV therapy is generally safe when properly administered, but there are important precautions to be aware of:

• Allergy testing — Reputable clinics always conduct allergy screening before a first infusion, especially for B vitamins and preservatives.
• G6PD test — Mandatory before NAD+ infusions. G6PD deficiency can cause serious haemolytic reactions with certain IV formulations.
• Kidney function — Renal panel required before high-dose Vitamin C (typically above 25g), as oxalate buildup can affect kidney health.
• Vein health — Frequent IV therapy can cause vein scarring. Clinics should rotate sites and use appropriate gauge needles.
