What Is NAD+?
NAD+ (Nicotinamide Adenine Dinucleotide) is a coenzyme present in every living cell in your body. It plays a central role in two of the most critical biological processes you have: producing cellular energy and repairing damaged DNA.
Without adequate NAD+, your mitochondria — the energy-generating powerhouses inside your cells — cannot function efficiently. Your DNA repair mechanisms slow. Your cells age faster. You feel it as fatigue, brain fog, slower recovery, and diminished resilience.
The problem is that NAD+ levels decline significantly with age. Research suggests that by your 50s, NAD+ levels may be less than half of what they were in your 20s. This decline is closely linked to many of the hallmarks of aging — metabolic slowdown, cognitive decline, and reduced physical endurance.
NAD+ injections bypass the digestive system entirely, delivering the coenzyme directly into the bloodstream for maximum bioavailability — something oral NAD+ precursors like NR or NMN cannot reliably achieve.
How NAD+ Injections Work
NAD+ functions as an electron carrier in the mitochondrial electron transport chain — the biochemical process that converts nutrients into ATP, the energy currency your cells run on. The more NAD+ available, the more efficiently this process runs.
Beyond energy production, NAD+ activates a family of proteins called sirtuins — often called longevity genes. Sirtuins regulate inflammation, DNA repair, circadian rhythm, and cellular stress responses. NAD+ is their required fuel.
NAD+ also activates PARP enzymes, which detect and repair broken DNA strands. This is particularly important for protecting against the accumulating DNA damage that drives aging and disease.
Key Biological Pathways
Mitochondrial Energy Production
NAD+ is a critical cofactor in the Krebs cycle and electron transport chain, directly enabling ATP synthesis in every cell.
Sirtuin Activation
Sirtuins (SIRT1–SIRT7) regulate gene expression, inflammation, and aging. They require NAD+ to function — no NAD+, no sirtuin activity.
DNA Repair via PARP
PARP enzymes consume NAD+ to repair single and double-strand DNA breaks, protecting genomic integrity over time.
Circadian Rhythm Regulation
NAD+ fluctuates in a circadian pattern and plays a key role in synchronizing your body clock with your metabolic processes.
NAD+ Injection Benefits
NAD+ therapy is used across a wide range of therapeutic goals. The most commonly reported and researched benefits include:
Sustained Cellular Energy
By restoring mitochondrial efficiency, NAD+ injections support consistent energy production at the cellular level — not the stimulant-driven spike of caffeine, but a cleaner, more stable baseline.
Cognitive Clarity & Neuroprotection
NAD+ supports neuronal health, reduces neuroinflammation, and activates SIRT1 — a sirtuin strongly associated with cognitive preservation and neuroprotection.
Accelerated Recovery
Athletes and active individuals use NAD+ to shorten recovery windows by supporting cellular repair and reducing oxidative stress accumulation after training.
Metabolic Support & Body Composition
NAD+ plays a direct role in fat oxidation and glucose metabolism. Replenishing levels supports healthier metabolic function and may assist with body composition goals.
Healthy Aging & Longevity
By activating sirtuins and PARP, NAD+ supports the cellular repair and gene regulation processes most closely linked to biological aging. It is one of the most researched compounds in longevity medicine.
Mood & Stress Resilience
NAD+ supports neurotransmitter synthesis and stress response pathways. Many patients report improved mood stability and reduced mental fatigue.
NAD+ Dosage & Administration
Dosage is determined by your prescribing provider based on your individual health profile. The following represents general clinical reference information only.
Subcutaneous Injection
The most common at-home administration route for NAD+. Injected just under the skin — typically in the abdomen or thigh — using a small insulin-style syringe.
Typical Dose
100mg per injection
Frequency
Daily to several times per week, depending on protocol
Onset
Effects are often noticeable within days to weeks of consistent use
Nasal Spray
A convenient alternative to injection. Absorbed through the nasal mucosa for rapid systemic delivery. Well-suited for patients who prefer a needle-free option.
Typical Dose
1mg per 0.1mL spray
Frequency
As directed by prescribing provider
Onset
Rapid absorption; effects vary by individual
Important Notes
- Your prescribing provider will determine the appropriate dose, frequency, and duration for your specific goals
- NAD+ injections are typically administered subcutaneously — not intravenously — in an at-home protocol
- Store as directed on your prescription label; refrigeration is typically required
- Do not adjust your dose without consulting your provider
Who Is NAD+ Therapy For?
NAD+ therapy may be a good fit if you are:
- Experiencing persistent fatigue, brain fog, or low energy that hasn't resolved with lifestyle changes
- Focused on healthy aging, longevity, or slowing biological age markers
- An athlete or highly active individual looking to accelerate recovery and reduce oxidative stress
- Interested in cognitive performance, neuroprotection, or mental clarity
- Working with a provider on metabolic health or body composition optimization
- Looking for a foundational cellular health intervention to complement other therapies like TRT or peptide therapy
Not for everyone: NAD+ therapy may not be appropriate for individuals with certain metabolic conditions or those taking specific medications. Your provider will review your health history during the async consultation.
