Measuring baseline NAD+ levels alongside biomarkers of inflammation, oxidative stress, and mitochondrial function with your doctor creates the foundation for measurable anti-aging results. Personalized NAD+ therapy—including oral precursors, IV infusions, and targeted lifestyle changes—can improve energy metabolism, DNA repair, and both physical and cognitive performance over time.
Because dosing, monitoring, and results vary based on your unique health profile, understanding your current symptoms is a critical first step. Take a free, instant, online symptom check to clarify what your body may be signaling and get personalized guidance on next steps in your healthcare journey.

How to Achieve Measurable Anti-Aging Results with Your Doctor
As we age, our cells lose efficiency in energy production, repair and detoxification. NAD+ (nicotinamide adenine dinucleotide) is a coenzyme critical to these processes. Research suggests boosting NAD+ levels may improve mitochondrial function, enhance DNA repair, support sirtuin activity and slow aspects of biological aging. To turn these insights into real, measurable benefits, partner closely with your physician. Here's how to get started.
Understand the Role of NAD+ in Aging
• Energy metabolism: NAD+ shuttles electrons in mitochondria, powering ATP production.
• DNA repair: Serves as a substrate for PARP enzymes that mend DNA breaks.
• Sirtuin activation: Sirtuins regulate gene expression, inflammation and stress resistance.
• Cellular signaling: NAD+ and its metabolites modulate calcium levels and circadian rhythms.
Gather Baseline Data
Before adding any intervention, collect objective measurements. Share results with your doctor to guide treatment and track progress.
Key assessments:
• Blood NAD+ or precursor levels (where available)
• Biomarkers of inflammation (CRP, IL-6)
• Oxidative stress markers (8-OHdG)
• Mitochondrial function tests (ATP production assays in specialized labs)
• Telomere length or epigenetic clock panels (e.g., DNAm age)
• Physical performance metrics (VO₂ max, grip strength, gait speed)
• Cognitive screenings (MoCA, Trail Making Test)
Oral Precursors
• Nicotinamide riboside (NR) and nicotinamide mononucleotide (NMN)
• Dosing typically ranges from 250–1,000 mg/day, split into two doses
• Advantages: easy administration, growing safety data
• Limitations: variable bioavailability; peak NAD+ rise 1–2 hours post-dose
IV NAD+ Therapy
• Direct infusion of NAD+ for rapid cellular uptake
• Typical protocols: 250–1,000 mg per session, weekly or biweekly
• Pros: higher immediate NAD+ levels, potential mood and fatigue benefits
• Cons: cost, need for clinical setting, possible infusion-related side effects
Lifestyle Synergies
• Intermittent fasting or time-restricted feeding to stimulate endogenous NAD+ synthesis
• Regular aerobic and resistance exercise to enhance mitochondrial biogenesis
• Sleep optimization (7–9 hours, consistent schedule) to support circadian NAD+ rhythms
• Stress reduction (meditation, yoga) to lower NAD+ consumption via PARP activation
Sample protocol framework:
Start with a conservative oral NR dose (250 mg twice daily) for 4–6 weeks.
Recheck NAD+ levels and inflammation markers.
If tolerated, increase to 500 mg twice daily or add NMN.
Introduce once-monthly IV NAD+ infusion for 3 months.
Monitor physical performance and cognitive tests every 3–6 months.
Track Progress with Regular Follow-Ups
Ongoing evaluation is essential. Schedule visits every 3–6 months to:
• Review lab results and marker trends
• Assess side effects (nausea, flushing, headache)
• Adjust dosing or switch formulations
• Update lifestyle recommendations
Expand Beyond NAD+
Anti-aging is multifaceted. Your doctor may suggest complementary therapies:
• Metformin or rapamycin analogs (under clinical guidance)
• Senolytic compounds (quercetin, fisetin) in research settings
• Hormone optimization (DHEA, testosterone, estrogen) based on deficiency
• Nutraceuticals (resveratrol, PQQ, CoQ10) to support mitochondrial health
Measure Functional and Quality-of-Life Outcomes
Subjective improvements matter. Document changes in:
• Energy levels, sleep quality and mood
• Skin elasticity, hydration and appearance
• Exercise capacity and recovery times
• Cognitive clarity, memory and focus
Use validated questionnaires (SF-36, WHO-QOL) alongside physical tests to capture a full picture.
Manage Expectations and Safety
While promising, NAD+ therapies are not a fountain of youth. Counsel with your doctor about:
• Realistic timelines (3–12 months for measurable shifts)
• Potential diminishing returns at higher doses
• Cost considerations and insurance coverage
• Monitoring for long-term safety data
When to Seek Immediate Medical Advice
Any sign of severe side effects or unexpected symptoms warrants prompt attention. If you experience:
• Chest pain, shortness of breath or palpitations
• Sudden neurological changes (weakness, vision loss)
• Severe allergic reactions (hives, swelling, difficulty breathing)
stop supplementation and speak to a doctor right away.
