NAD+ IV Infusion & IM Therapy

Intravenous NAD+ (nicotinamide adenine dinucleotide) infusions and intramuscular NAD+ injections at Radiant Health SF for cellular energy support, longevity, cognitive function, and recovery. NAD+ is a coenzyme central to mitochondrial energy production and sirtuins, the longevity-associated proteins that regulate cellular repair. Administered under naturopathic physician supervision. Duration varies by dose — typically 90 to 180 minutes for IV infusions.

Radiant Health SF offers intravenous NAD+ infusions and intramuscular NAD+ injections as part of its longevity and anti-aging treatment menu. NAD+ (nicotinamide adenine dinucleotide) is a coenzyme present in every cell in the body that plays a central role in mitochondrial oxidative phosphorylation — the process by which cells convert nutrients into ATP, the primary energy currency. NAD+ levels decline significantly with age (studies estimate a 40–60% reduction between young adulthood and middle age), and this decline is associated with reduced mitochondrial function, decreased cellular repair capacity, impaired sirtuin activity, and accumulated DNA damage. Sirtuins are a family of NAD+-dependent deacetylase enzymes (SIRT1–SIRT7) that regulate processes including DNA repair, inflammation control, metabolic regulation, and mitochondrial biogenesis; their activity is directly gated by intracellular NAD+ availability. By delivering NAD+ intravenously — bypassing digestive breakdown that limits oral NMN or NR supplementation — IV infusions are thought to more rapidly and substantially raise intracellular NAD+ levels, providing substrate for sirtuin activation and mitochondrial repair pathways. Clinical applications at Radiant Health SF include general anti-aging and longevity support, cognitive function and mental clarity, athletic performance and recovery, and as an adjunct to the clinic's hormone and epigenetic testing programmes. IV NAD+ infusions are administered at slow drip rates over 90 to 180 minutes to reduce common side effects such as chest tightness and nausea that occur with faster infusion rates; IM injections deliver a smaller NAD+ dose more rapidly for maintenance between infusions. All infusions are supervised by the clinic's naturopathic physicians.
