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.
The half-life of NAD+ is ~1 hour for NAD+ itself; precursors (NMN, NR) have variable half-lives. This means dosing once daily is typical to maintain stable levels. The half-life directly affects how long NAD+ remains active and influences optimal injection timing.
What Is the Half-Life of NAD+?
The half-life of NAD+ is ~1 hour for NAD+ itself; precursors (NMN, NR) have variable half-lives. This is the time it takes for blood concentration to drop by 50% after administration.
Understanding half-life is essential for designing effective dosing protocols — it determines how often you need to administer NAD+ to maintain therapeutic blood levels.
What Does NAD+'s Half-Life Mean for Dosing?
With a half-life of ~1 hour for NAD+ itself; precursors (NMN, NR) have variable half-lives, NAD+ requires dosing once daily to maintain stable levels. The standard dosage of 250-1000 mg daily (NR/NMN precursors); 5-10 mg daily (NADH) via oral (tablets, capsules, sublingual) accounts for this pharmacokinetic profile.
After approximately 4-5 half-lives, NAD+ reaches steady-state concentration — the point where the amount being absorbed equals the amount being eliminated. For NAD+, this occurs within the first few days of consistent dosing.
When Is the Best Time to Inject NAD+?
Optimal timing depends on your research goals. A half-life of ~1 hour for NAD+ itself; precursors (NMN, NR) have variable half-lives means peak blood levels occur shortly after injection and decline predictably.
Common timing approaches: morning injection for daytime activity, pre-bed injection for overnight effects, or split dosing (once daily) for more stable levels throughout the day.
How Does NAD+'s Half-Life Compare to Similar Peptides?
NAD+ is a Coenzyme, metabolite, cellular cofactor. Its half-life of ~1 hour for NAD+ itself; precursors (NMN, NR) have variable half-lives positions it with a shorter duration of action compared to some alternatives in this class.
Shorter half-lives require more frequent dosing but allow for more precise control. Longer half-lives are more convenient but carry risk of accumulation.

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.
