NAD+
A central metabolic coenzyme studied for energy metabolism and cellular ageing.
The cell's energy currency.
NAD+ is a coenzyme present in every living cell, central to energy metabolism and to the activity of sirtuins and PARPs - enzymes tied to repair and ageing. Cellular NAD+ declines with age, which is why restoring it is one of the most active areas in longevity research.
At a glance
Settled biology, contested claims.
NAD+'s role is textbook: it is the electron carrier at the centre of energy metabolism and the required cofactor for sirtuins and PARPs - enzymes tied to repair and ageing.
The contested part is translation. Tissue NAD+ falls with age, and precursors raise it in studies, but whether restoring it changes human ageing outcomes and whether injected forms add anything over oral precursors - remains unproven.
Reading the evidence honestly
Not every claim made about BPC-157 carries equal weight. Apex Academy separates findings into three tiers based on how well-replicated and how directly applicable to humans the underlying research actually is.
- Central role in energy metabolism (textbook)
- Substrate for sirtuins and PARPs
- Documented age-related tissue decline
- Precursor supplementation raises NAD+ markers
- Metabolic and mitochondrial signals
- Animal lifespan/healthspan data
- Human lifespan extension
- Direct IV/injected NAD+ benefit claims
- Optimal restoration strategy
How it works
Redox carrier
Shuttles electrons through cellular respiration.
EstablishedSirtuin fuel
Required cofactor for sirtuin deacetylases.
EstablishedDNA repair
Supports PARP-mediated repair activity.
MechanisticRestoration
Precursors (NMN/NR) raise NAD+ in studies.

Signs of a quality compound
NAD+ biology is textbook; the contested part is whether and how supplementation translates to human ageing outcomes. Injectable/IV NAD+ research applications remain investigational.
