NAD+ (Nicotinamide Adenine Dinucleotide) is the master coenzyme of cellular energy and longevity — levels decline 50% by age 40. We replenish them.
NAD+ is a coenzyme found in every cell of your body, essential for over 500 enzymatic reactions — including the production of ATP (cellular energy), DNA repair, gene expression, and the activation of sirtuins (longevity proteins). It is arguably the most important molecule in aging biology.
NAD+ levels decline approximately 50% between ages 20 and 60. This decline is now understood to be a primary driver of age-related cellular dysfunction, reduced energy production, impaired DNA repair, and the hallmarks of aging.
At Quantum Longevity, we offer NAD+ as subcutaneous injections — highly bioavailable, physician-prescribed, and far more effective than oral supplements which have poor absorption. Regular NAD+ therapy replenishes cellular reserves, activates sirtuins and PARP enzymes, and supports comprehensive cellular rejuvenation.
NAD+ is the central molecule in mitochondrial ATP synthesis. Restoring levels directly improves cellular energy production and reduces chronic fatigue.
Activates PARP enzymes that repair damaged DNA — a fundamental mechanism of aging prevention. NAD+ is required for sirtuin activation (SIRT1–7), the longevity proteins studied by the world's leading aging researchers.
NAD+ supports neuronal function, synaptic plasticity, and neuroprotection. Many patients report sharper thinking, better memory, and reduced brain fog.
Plays a central role in glucose and fatty acid metabolism. Improving NAD+ status enhances insulin sensitivity and metabolic flexibility.
NAD+ IV therapy has demonstrated efficacy in supporting recovery from substance dependence and improving mood disorders — areas of growing clinical interest.
Activates sirtuins that deacetylate NF-κB, reducing inflammatory gene expression and chronic systemic inflammation.
Discuss your energy, cognition, and longevity goals with a licensed provider.
Provider determines dose (100–500mg), frequency, and route (SubQ injection or IV) based on your goals.
Medication delivered. SubQ self-injection or scheduled IV sessions depending on your protocol.
Regular follow-ups to assess energy, cognition, and biomarker response. Protocols adjusted as needed.
Most accessible approach. 100–500mg subcutaneous injection, daily to 3x/week. Self-administered at home. Good for long-term maintenance and cellular optimization.
NAD+ synergizes with MOTS-c (mitochondrial peptide), Semax (neuroprotection), and resveratrol/NMN supplements for comprehensive longevity protocols.
