NAD+ — Cellular Energy & Vitality Support
NAD+ (nicotinamide adenine dinucleotide) is a coenzyme present in every cell of the body and central to the processes that produce cellular energy. It plays a fundamental role in mitochondrial function, DNA repair, and the activation of sirtuins — proteins linked to longevity and metabolic regulation. NAD+ levels decline significantly with age and with lifestyle factors including chronic stress, poor sleep, alcohol use, and intense physical demands. IV NAD+ therapy delivers the coenzyme directly into the bloodstream, bypassing digestive absorption limits and achieving tissue concentrations that oral supplements cannot consistently match.
Why NAD+ Levels Decline
NAD+ depletion is driven by multiple converging factors: the natural slowing of biosynthesis with age, increased consumption by DNA repair enzymes (PARPs) responding to accumulated oxidative damage, activation of the CD38 enzyme by chronic inflammation, and depletion through alcohol metabolism. By the time most adults reach their 40s and 50s, cellular NAD+ levels may be 50 percent or less of their youthful baseline — a decline that impairs every NAD+-dependent process, from energy production to cellular maintenance.
What IV NAD+ Supports
NAD+ IV therapy is used in wellness programs focused on energy support, mental clarity and focus, cellular wellness, and vitality during high-demand periods. Many patients report improved energy and mental sharpness during and after infusions. NAD+ is also frequently paired with other peptide and IV therapies as part of comprehensive longevity and recovery protocols. Sessions at Vivere typically take two to four hours and are administered by licensed medical professionals.
IV vs. Oral NAD+ Supplementation
Oral NAD+ precursors — including NMN (nicotinamide mononucleotide) and NR (nicotinamide riboside) — are commonly used and have supporting evidence for raising cellular NAD+ levels. However, oral bioavailability varies, and tissue concentrations achieved orally may not match those achievable with IV delivery. IV NAD+ bypasses the digestive system entirely, delivering the coenzyme directly into circulation for immediate systemic availability. For patients seeking the most reliable and rapid NAD+ repletion, IV administration offers the most direct route.
Frequently Asked Questions
How long does a NAD+ IV session take?
NAD+ infusions are administered slowly to minimize side effects — typically over two to four hours depending on dose. Common transient sensations during infusion include chest tightness, nausea, or flushing, which resolve when the infusion rate is slowed. Your Vivere provider will guide the infusion rate based on your comfort and response.
How many NAD+ sessions are recommended?
The frequency and number of sessions depends on your goals and starting point. Some patients benefit from an initial series of sessions followed by monthly maintenance infusions; others incorporate NAD+ as part of periodic wellness protocols. Your provider will recommend a schedule based on your individual wellness plan.
