NAD+ is a research compound. It is not approved by the FDA or any regulatory body for human use. This article is for educational and informational purposes only. Nothing here constitutes medical advice. Consult a qualified physician before considering any peptide use.
NAD+ (Nicotinamide Adenine Dinucleotide) is a Coenzyme, metabolite, cellular cofactor researched for increased ATP production, mitochondrial function, DNA repair, sirtuin activation, metabolic flexibility, anti-aging, cognitive function. For beginners, start at the lower end of the dosage range (250-1000 mg daily (NR/NMN precursors); 5-10 mg daily (NADH)) and administer once daily via oral (tablets, capsules, sublingual).
What Is NAD+?
NAD+ (Nicotinamide Adenine Dinucleotide) is a Coenzyme, metabolite, cellular cofactor. Endogenous molecule synthesized from dietary tryptophan or nicotinamide (vitamin B3); exists in all living cells as essential cellular energy currency.
It is researched for its potential effects on increased ATP production, mitochondrial function, DNA repair, sirtuin activation, metabolic flexibility, anti-aging, cognitive function. Not a peptide but a universal metabolic cofactor — the most fundamental molecule in cellular energy production, making it the foundation that all other anti-aging interventions build upon.
For beginners: This guide assumes no prior peptide experience. We'll cover everything from what NAD+ is to how to reconstitute, inject, and structure your first cycle.
How Does NAD+ Work?
Functions as electron carrier in redox reactions for ATP generation. Acts as cosubstrate for sirtuins (NAD+-dependent deacetylases) that regulate protein acetylation and gene expression related to longevity. Serves as substrate for PARPs (poly-ADP-ribose polymerases) in DNA repair. Levels decline approximately 50% between ages 40 and 60.
Understanding the mechanism helps set realistic expectations about what NAD+ can and cannot do.
How Do You Get Started With NAD+?
Step 1 — Source: Purchase NAD+ from a vendor with third-party Certificate of Analysis (COA) testing. This confirms purity (aim for 98%+) and rules out contamination.
Step 2 — Supplies: You'll need bacteriostatic water, insulin syringes (1mL/100-unit), alcohol swabs, and a clean workspace.
Step 3 — Reconstitute: Add BAC water to the NAD+ vial — use our peptide calculator for exact amounts. Let the water run down the side of the vial; never spray directly on the powder. Swirl gently.
Step 4 — Dose: Draw 250-1000 mg daily (NR/NMN precursors); 5-10 mg daily (NADH) using the calculator's syringe unit conversion.
Step 5 — Inject: Clean the injection site with alcohol. Pinch a fold of abdominal fat and insert the needle at 45° for subcutaneous injection. Push the plunger slowly and hold for 5 seconds.

Dosage: Start at the lower end of 250-1000 mg daily (NR/NMN precursors); 5-10 mg daily (NADH). This lets you assess tolerance before committing to a full cycle.
Frequency: once daily via oral (tablets, capsules, sublingual).
Duration: continuous supplementation; no cycling required. Don't cut cycles short — many Coenzyme, metabolite, cellular cofactor effects take weeks to fully manifest.
Off-cycle: Plan a 4-week break before starting another cycle.
What Side Effects Should Beginners Watch For?
NADH well-tolerated. High-dose nicotinamide (>3000 mg) can cause nausea, skin flushing, elevated liver enzymes. NMN and NR precursors show fewer side effects with no flushing or liver toxicity reported at standard doses.
As a beginner, track everything — dose, time, injection site, and any effects (positive or negative). This data helps optimize future cycles.
What Are Common Beginner Mistakes?
Not using BAC water: Sterile water lacks the preservative that prevents bacterial growth. Always use bacteriostatic water.
Inconsistent dosing: Skipping doses or varying timing significantly reduces outcomes. Set a daily alarm.
Poor storage: Reconstituted NAD+ must stay refrigerated at 2-8°C. Leaving it at room temperature degrades the compound rapidly.
Buying cheap: Low-cost peptides without COA testing may be underdosed, contaminated, or mislabeled. Quality matters more than price.
Bottom Line for NAD+ Beginners
Start at the lower end of 250-1000 mg daily (NR/NMN precursors); 5-10 mg daily (NADH), dose once daily, cycle for continuous supplementation; no cycling required, and track everything. Source from COA-tested vendors and follow proper reconstitution protocol.

Frequently Asked Questions
What is NAD+?
NAD+ (Nicotinamide Adenine Dinucleotide) is a Coenzyme, metabolite, cellular cofactor. Endogenous molecule synthesized from dietary tryptophan or nicotinamide (vitamin B3); exists in all living cells as essential cellular energy currency. It is researched for increased ATP production, mitochondrial function, DNA repair, sirtuin activation, metabolic flexibility, anti-aging, cognitive function.
What is the recommended NAD+ dosage?
Common dosages: 250-1000 mg daily (NR/NMN precursors); 5-10 mg daily (NADH) administered once daily via oral (tablets, capsules, sublingual). Cycle length: continuous supplementation; no cycling required. Half-life: ~1 hour for NAD+ itself; precursors (NMN, NR) have variable half-lives. Use our peptide calculator for exact reconstitution math.
What are the side effects of NAD+?
NADH well-tolerated. High-dose nicotinamide (>3000 mg) can cause nausea, skin flushing, elevated liver enzymes. NMN and NR precursors show fewer side effects with no flushing or liver toxicity reported at standard doses.
Is NAD+ safe?
NAD+ has shown a favorable safety profile in research. NAD+ precursors (NR, NMN) legally available as dietary supplements in US. NADH available as supplement. Not FDA-approved as drug. All research should follow appropriate safety protocols.
