NAD+ IV Infusion & IM Therapy

Intravenous NAD+ infusions and intramuscular NAD+ injections at Radiant Health SF, offered for cellular energy support, cognitive function, mitochondrial health, and anti-aging. NAD+ is a coenzyme central to energy production and sirtuin-mediated cellular repair. Administered under naturopathic physician supervision. IV infusion sessions typically run 90 to 180 minutes depending on dose.

Radiant Health SF offers intravenous NAD+ (nicotinamide adenine dinucleotide) infusions and intramuscular NAD+ injections as part of its longevity and anti-aging service menu. NAD+ is a coenzyme present in every cell of the body, playing a central role in mitochondrial oxidative phosphorylation — the process by which cells convert nutrients into ATP, the cell's primary energy currency. NAD+ levels decline significantly with age — studies suggest a 40 to 60 percent 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 over time. Sirtuins are a family of NAD+-dependent deacetylase enzymes (SIRT1 through SIRT7) that regulate processes including DNA damage repair, inflammatory signalling, metabolic regulation, and mitochondrial biogenesis; their activity is directly gated by intracellular NAD+ availability. Delivering NAD+ intravenously bypasses the digestive breakdown that limits the bioavailability of oral NMN or NR supplementation, and is thought to more rapidly and substantially raise intracellular NAD+ levels, providing substrate for sirtuin activation and repair pathways. Clinical applications at Radiant Health SF include general longevity and anti-aging support, cognitive function and mental clarity, athletic performance and recovery, and as a complement 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 transient chest tightness and nausea that occur with faster infusion rates; IM injections deliver a smaller dose more quickly for maintenance between infusions. All infusions are supervised by the clinic's naturopathic physicians.
