Is NAD+ considered natty?

NAD+ is generally regarded as compatible with natural bodybuilding. Most sanctioning bodies do not prohibit its therapeutic use, though rules vary by federation.

Is NAD+ on the WADA prohibited list?

As of the current prohibited list, NAD+ is not explicitly banned by WADA, though regulations can change. Always verify against the current year's WADA prohibited list before competition.

How is NAD+ administered?

NAD+ is typically administered via: oral supplementation, intravenous infusion, subcutaneous injection. Dosage and administration protocols vary; see the Dosage section for details.

NAD+ (also known as NAD+ or Nicotinamide Adenine Dinucleotide) is a therapeutically researched peptide studied for its effects on anti-aging, recovery, metabolic health. Essential cellular coenzyme for energy, DNA repair, and aging. Oral precursors (NMN/NR) or IV boost NAD+ levels. Cellular benefits proven, longevity claims unproven.

NAD+ (Nicotinamide Adenine Dinucleotide) is a critical coenzyme found in all living cells that plays essential roles in cellular metabolism, energy production, DNA repair, and aging processes. NAD+ levels naturally decline with age (up to 50% by middle age), contributing to mitochondrial dysfunction, reduced cellular repair capacity, and various age-related conditions. NAD+ serves as a crucial substrate for sirtuins (SIRT1-7) and poly(ADP-ribose) polymerase (PARP) enzymes that regulate cellular longevity, stress adaptation, and DNA repair mechanisms.

Natty status

NAD+ is generally regarded as compatible with natural bodybuilding, though competitive federations may differ. See § Natty status.

Overview

While NAD+ itself is poorly absorbed orally, precursor compounds including Nicotinamide Riboside (NR) and Nicotinamide Mononucleotide (NMN) effectively increase NAD+ levels via salvage pathways.

Clinical trials demonstrate NR/NMN supplementation (250-1000mg daily) safely elevates blood NAD+ levels, with observed improvements in mitochondrial function, insulin sensitivity, muscle performance, and cardiovascular markers.

However, experts emphasize there is no conclusive evidence that NAD+ supplementation extends human lifespan despite cellular benefits.

Common administration methods include oral supplementation (NR/NMN), IV infusions (500-1500mg, 2-4 hours), and subcutaneous injections (50-100mg weekly).

Side effects are generally mild and transient, including nausea, flushing, headache, and GI discomfort.

Potential concerns include unknown long-term safety profile, theoretical tumorigenesis risk (unproven in humans), and significant cost ($1000+ for IV sessions).

NAD+ restoration represents a promising but still investigational approach to cellular regenerative medicine, requiring more robust long-term human clinical trials to establish definitive therapeutic applications and longevity benefits.

Mechanism of action

Boosts cellular energy production and DNA repair. Activates longevity enzymes. Improves metabolism and mitochondrial health. Cellular benefits proven, human longevity unproven.

Reported effects

Effects reported in the literature and from preclinical models include:

Nicotinamide and NAD+ precursors enhance mitochondrial function and cognitive resilience in preclinical Alzheimer's disease models by counteracting PARP1-driven NAD+ depletion and associated neuroinflammation ^[2] Preclinical
NAD+-dependent sirtuin SIRT2 is mechanistically linked to aging and the development of neurodegenerative and cancerous diseases, making NAD+ availability central to cellular longevity pathways ^[1] Preclinical
Inherited deficiencies in NAD biosynthesis and recycling cause multi-system neurologic impairment including seizures, movement disorders, and neurodevelopmental deficits, underscoring the essentiality of adequate NAD levels for neurological health ^[3] Preclinical

NAD+ is generally regarded as compatible with the natty designation, particularly when used for therapeutic healing purposes. Opinions vary across natural bodybuilding federations, and athletes who compete should consult the rulebook of their respective sanctioning body.^[4]
