NAD+ IV (250mg)

A 120-minute intravenous infusion of 250 milligrams of nicotinamide adenine dinucleotide (NAD+), a coenzyme essential for cellular energy production, DNA repair, and sirtuin activation. NAD+ levels decline with age, and direct intravenous supplementation delivers the active molecule to the bloodstream without the metabolic conversion steps required by oral precursors.

NAD+ (nicotinamide adenine dinucleotide) is a coenzyme found in every living cell, functioning as a critical substrate for hundreds of enzymatic reactions. It serves as an electron carrier in the mitochondrial electron transport chain — the process by which cells convert nutrients into adenosine triphosphate (ATP), the universal energy currency. NAD+ is also a required cofactor for sirtuins, a family of enzymes involved in DNA repair, gene expression regulation, and cellular stress response — processes that have been extensively studied in the context of biological ageing. Research has established that NAD+ levels decline significantly with age. By middle age, cellular NAD+ concentrations may be half of what they were in youth. This decline is associated with decreased mitochondrial function, impaired DNA repair capacity, increased cellular senescence, and the accumulation of damage that characterises ageing at the cellular level. Higher Health's NAD+ IV protocol delivers 250 milligrams of NAD+ directly into the bloodstream over approximately two hours. The extended infusion time is deliberate — NAD+ delivered too quickly can cause temporary side effects including flushing, chest tightness, nausea, and muscle cramping. The clinical team at Higher Health monitors the drip rate throughout and adjusts based on individual tolerance. Most clients find the sensation mild and manageable, particularly from the second session onward. The two-hour session provides dedicated time for rest and reflection. Complimentary red light therapy is available during the infusion, adding photobiomodulation — which independently supports mitochondrial function through cytochrome c oxidase activation — to create a complementary dual-pathway approach to cellular energy enhancement. Dr. Tara Campbell ND, who has extensive experience with NAD+ protocols, assesses each client during the initial consultation to determine appropriate dosing and frequency. A common introductory protocol involves weekly infusions for four to six weeks as a loading phase, followed by monthly maintenance sessions. Clients frequently report improved mental clarity, sustained energy, better sleep quality, and enhanced exercise recovery.
