Overview

While NAD+ (nicotinamide adenine dinucleotide) is technically a coenzyme rather than a peptide, it is a central component of peptide therapy protocols targeting mitochondrial function and aging. NAD+ levels decline 50%+ with aging, contributing to mitochondrial dysfunction, reduced DNA repair, and epigenetic aging. IV NAD+ therapy and oral NAD+ precursors (NMN, NR) are widely used alongside mitochondrial peptides (SS-31, MOTS-c) and NNMT inhibitors (5-Amino-1MQ) in comprehensive anti-aging protocols.

Mechanism of Action

NAD+ serves as a cofactor for: sirtuins (SIRT1-7) regulating gene expression, DNA repair, and metabolism; poly(ADP-ribose) polymerases (PARPs) for DNA damage repair; CD38/CD157 ectoenzymes regulating calcium signaling; and the electron transport chain for ATP synthesis. Restoration of NAD+ reactivates these pathways. When combined with NNMT inhibitors like 5-Amino-1MQ, the combination addresses both supply (NAD+ therapy) and conservation (NNMT inhibition) for sustained cellular effects.

Potential Benefits

  • Restoration of mitochondrial electron transport chain efficiency
  • Reactivation of SIRT1-7 longevity pathways
  • Enhanced DNA repair capacity via PARP reactivation
  • Improved cellular energy metabolism
  • Synergistic with MOTS-c, SS-31, and 5-Amino-1MQ in anti-aging stacks

Dosage Protocols

The following reflects doses used in published research studies. This is not medical advice. Consult a qualified healthcare professional.

Typical Range250-1000 mg/day oral precursors; 100-1000 mg IV NAD+
Beginner250-500 mg NMN or NR orally daily
Intermediate500-1000 mg NMN daily; or 250-500 mg IV weekly
Advanced1000 mg IV NAD+ 1-3x/week; high-dose NMN/NR orally
Cycle DurationContinuous oral; IV typically 4-8 week courses
Cycle OffIV courses: 4-8 weeks off; oral precursors may be continued indefinitely

IV NAD+ provides the most direct cellular repletion. IV administration often causes mild flushing, chest tightness, or nausea during infusion — slow administration rate resolves this. NAD+ levels naturally decline ~50% by age 50.

Routes of Administration

Oral Moderate

NMN and NR are oral precursors that raise cellular NAD+; convenient and cost-effective vs IV; NMN may convert to NR in gut prior to absorption

Subcutaneous Injection High

Direct NAD+ injection; increasingly used as alternative to IV infusion; practical and cost-effective for home use
