The fundamental advantage of intravenous nutrient delivery is complete bioavailability. When nutrients are administered directly into the bloodstream, 100% of the dose reaches the circulation — bypassing the digestive system entirely, with no loss to absorption variability, gut transit, or first-pass metabolism. Plasma concentrations of nutrients can be achieved that are simply not possible through any oral route, regardless of dose.
The Myers Cocktail: Where It All Began
Developed by Baltimore physician John Myers in the 1970s and refined through decades of clinical use, the Myers Cocktail combines magnesium, calcium, B vitamins, and high-dose vitamin C. It remains the most widely used and studied IV nutrient protocol in integrative medicine, with clinical evidence supporting its use for chronic fatigue, fibromyalgia, migraine, upper respiratory infection, and generalised depletion. Most clients describe it as deeply relaxing — the magnesium component in particular producing a marked physiological calming effect as it enters the circulation.
"The most direct route to cellular health — nothing lost in translation."
NAD+ Infusion: The Longevity Protocol
NAD+ infusion is increasingly regarded as one of the most significant developments in functional and longevity medicine. At concentrations achievable only intravenously, NAD+ replenishes intracellular reserves across all tissue, restoring the coenzyme activity essential to mitochondrial energy production, DNA repair, and sirtuin activation. Sessions typically run for 2 to 4 hours — the slower administration allows the body to integrate the infusion comfortably. Effects reported are consistently striking: a restoration of energy that feels qualitatively different from stimulant-based alertness, improved cognitive clarity, and in those with addiction histories, a notable reduction in cravings.
Glutathione: The Detox Infusion
Glutathione — the body's master antioxidant — is depleted by chronic stress, illness, ageing, alcohol, and environmental toxin exposure. IV delivery achieves plasma concentrations many times higher than oral supplementation, directly supporting the liver's detoxification pathways and providing antioxidant protection at a cellular level. It is frequently used as a standalone detoxification protocol and as an adjunct to other infusions.

Who Benefits Most from IV Therapy?
IV infusion therapy is particularly valuable for those experiencing significant physiological depletion — from chronic stress, overwork, illness, post-viral fatigue, or the cumulative deficit of inadequate nutrition. It is also used proactively by those who are functionally well but want to optimise their baseline: supporting performance, recovery, and longevity through regular nutritional maintenance at a level oral supplementation cannot match.
Please note: IV infusions are administered by trained practitioners in a clinical setting. A health consultation is required prior to treatment. These are wellness services and do not constitute medical treatment or diagnosis.
