NAD+

Also: Nicotinamide Adenine Dinucleotide, NAD Plus, Beta-Nicotinamide Adenine Dinucleotide

⚡Longevity

How It Works

NAD+ is a critical coenzyme in every cell, essential for mitochondrial energy production (oxidative phosphorylation), DNA repair via PARP and sirtuin activation, and circadian rhythm regulation. Levels decline ~50% between ages 40-60, contributing to metabolic dysfunction and aging.

Key Studies

NAD+ decline is a driver of aging

Rajman et al. (Cell Metabolism): Comprehensive review demonstrating NAD+ decline as a hallmark of aging, with restoration improving mitochondrial function, stem cell renewal, and lifespan in animal models.

CD38 dictates age-related NAD decline and mitochondrial dysfunction

Camacho-Pereira et al. (Cell Metabolism): Identifies CD38 as the primary NAD-consuming enzyme that increases with age, explaining the progressive NAD+ decline.

Safety Notes

Generally well-tolerated. IV NAD+ infusions may cause chest tightness, nausea, and cramping during administration. Subcutaneous injection is better tolerated. Oral precursors (NMN, NR) have good safety profiles in clinical trials.

Dosing Protocol

RouteSubQ

Dose Range50000-200000 mcg

FrequencyDaily

TimingMorning

Cycle Length4-12 weeks

BAC Water2 ml / 500mg vial

SubQ: 50-200mg daily. IV: 250-500mg over 2-4 hours. Start low — rapid NAD+ elevation can cause nausea and flushing. Oral precursors (NMN/NR) are an alternative.

Half-Life Visualization

Expected Timeline

Week 1

Increased energy, mental clarity, reduced brain fog

Weeks 2-4

Improved exercise recovery, better sleep quality, mood stabilization

Month 2-3

Measurable improvements in metabolic markers, sustained energy throughout the day

Long-term

NAD+ level restoration; potential longevity benefits (animal data for lifespan extension)
