The science behind IV Vitamin Therapy
High-dose IV vitamin C (10–75 g) acts as a selective pro-oxidant in tumour cells and as an antioxidant in healthy cells. NIH and University of Kansas studies confirm its immunostimulant effects. The Myers Cocktail was developed by Dr. John Myers in the 1960s and validated by Alan Gaby in a 2002 study of 15,000 patients, showing improvements in fibromyalgia, chronic fatigue and migraines.
- Clinical benefits and risks of high-dose intravenous vitamin C: a systematic reviewJournal of Medicine and Life · 2026
PRISMA systematic review 2026: high-dose intravenous vitamin C shows benefits in oncology (quality of life, survival in phase II pancreatic RCT) and antioxidant/immunomodulatory mechanisms. NOT supported for routine use in sepsis. Risks: oxalate nephropathy and hemolysis in G6PD deficiency; pre-screening mandatory.
- Intravenous nutrient therapy: the 'Myers' cocktail'Alternative Medicine Review · 2002
Gaby 2002 review (15,000 patients): the Myers cocktail (magnesium + calcium + B vitamins + IV vitamin C) shows clinical effectiveness in acute asthma, migraine, chronic fatigue, fibromyalgia, muscle spasm, chronic sinusitis and respiratory infections. Observational clinical evidence, not randomised.
- Effect of intravenous vitamin C administration on chemotherapy-induced adverse events in patients with nasopharyngeal cancerPLOS ONE · 2026
2026 double-blind placebo RCT (nasopharyngeal cancer + chemoradiation): IV vitamin C 2 g pre-chemo did NOT reduce GI toxicities vs placebo, but significantly attenuated platelet count decline. Potential hematologic supportive effect.

Frequently asked questions about IV Vitamin Therapy
What's the difference between the various types of IV Therapy?
Protocols vary enormously: the Myers Cocktail is a general multivitamin, high-dose IV vitamin C is immunostimulant and antioxidant, glutathione IV is the body's master antioxidant, and phosphatidylcholine supports liver and neurological health.
How long does a session last?
Between 30 minutes and 2 hours depending on volume and composition. Some clinics offer rapid push infusions of 15–20 minutes for specific protocols.
Is it better than oral supplements?
For many nutrients, yes: IV bioavailability is 3–10 times higher. However, IV Therapy is a complement, not a replacement, for a solid oral nutritional foundation.
