Overview
What it is.
NAD+ is a coenzyme — not a peptide — central to how every cell produces and uses energy, with levels that decline with age. It is one of the most frequently requested compounds alongside peptide research protocols and is included here for that reason.
Research Areas
- Studied for its potential role in cellular-energy-metabolism research
- Studied for its potential role in mental-clarity and focus research
- Studied for its potential role in cellular-aging-process research

Research Deep-Dive
How it works.
NAD+ (nicotinamide adenine dinucleotide) is a coenzyme — not a peptide — that every cell in the body relies on to produce and use energy. Levels decline measurably with age, which is why it's studied and offered as part of longevity-focused wellness protocols alongside peptides.
NAD+ is a central cofactor in mitochondrial energy metabolism and in DNA-repair and cell-signaling pathways (including sirtuin activity). Supplementing it, or its precursor molecules, is studied as a way to help maintain the cellular NAD+ pool that supports these processes as natural levels fall with age.
Use Cases Explored
- Studied for a potential role in cellular energy metabolism
- Studied for a potential role in mental clarity and focus
- Studied for a potential role in supporting healthy aging processes
- Studied as a companion to peptide-based longevity protocols
The Evidence
Oral precursor trials (NR, NMN) — target engagement
Multiple randomized, placebo-controlled trials of oral NAD+ precursors (nicotinamide riboside, nicotinamide mononucleotide) in middle-aged and older adults consistently show the supplements are well tolerated and reliably raise circulating NAD+ levels.
Functional outcome trials — mixed to limited
The same trials have generally not shown clear improvements in cardiovascular, cognitive, or muscle-strength outcomes; a 2025 systematic review found human effects on metabolic and performance outcomes remain mixed, with small sample sizes and short durations as recurring limitations.
IV/injectable-route trial data
A 2025 PRISMA-guided systematic review found no eligible outcomes trials specifically testing IV or IM NAD+ for anti-aging or wellness purposes — the direct-injection route used in many clinics has less formal trial evidence behind it than oral precursor supplementation.
Animal research
Preclinical studies in rodents show more consistent benefits for metabolism, inflammation, and mitochondrial function, but that evidence has not yet reliably translated into measured human functional gains.
