NAD+

Also known as: Nicotinamide Adenine Dinucleotide, NAD, Coenzyme I

The essential coenzyme for cellular energy and DNA repair — levels drop 50% by age 60. Direct supplementation is a cornerstone of modern anti-aging protocols.

// Overview

What is NAD+?

NAD+ (Nicotinamide Adenine Dinucleotide) is a coenzyme found in every living cell, essential for over 500 enzymatic reactions including cellular energy production (ATP synthesis), DNA repair (PARP enzymes), gene expression regulation (sirtuins), and calcium signaling (CD38).

NAD+ levels decline approximately 50% between ages 40 and 60, and this decline is now considered a hallmark of aging. Reduced NAD+ impairs mitochondrial function, DNA repair capacity, and sirtuin activity — all critical drivers of age-related disease and functional decline.

NAD+ can be supplemented directly via IV or subcutaneous injection, or indirectly through precursors like NMN (nicotinamide mononucleotide) and NR (nicotinamide riboside). Direct NAD+ administration bypasses the biosynthetic pathway, providing immediate cellular availability but requiring injection due to poor oral bioavailability of NAD+ itself.

// How It Works

How NAD+ Works

NAD+ is a central metabolic cofactor operating through several critical pathways:

  1. Mitochondrial energy production — NAD+ is required for the electron transport chain (Complex I) and the citric acid cycle. Without adequate NAD+, ATP production declines and cellular energy drops.
  2. Sirtuin activation — Sirtuins (SIRT1-7) are NAD+-dependent deacetylases that regulate gene expression, DNA repair, inflammation, and metabolism. They are the primary mediators of caloric restriction's anti-aging effects.
  3. PARP-mediated DNA repair — PARP enzymes consume NAD+ to repair DNA damage. When NAD+ is depleted, DNA damage accumulates — a driver of aging and cancer.
  4. CD38 and immune regulation — CD38 is the largest consumer of NAD+ and increases with age. NAD+ supplementation helps overcome CD38-driven depletion.
  5. Circadian rhythm — NAD+ oscillates with circadian rhythm and is required for CLOCK/BMAL1 transcription factor activity.

Dosage Information (User-Reported)

Disclaimer: Dosage information is compiled from user reports and published research. This is not medical advice. Consult a healthcare professional before use.
Level Dose Frequency Duration
Subcutaneous 50-100 mg Daily or every other day 4-12 weeks
IV Drip (Clinical) 250-500 mg Weekly or biweekly 4-8 sessions
NMN (Oral) 250-1000 mg Daily (oral capsule) Ongoing
NR (Oral) 300-600 mg Daily (oral capsule) Ongoing

What to Expect

Day 1 (IV)

Immediate mental clarity and energy boost. Some discomfort during infusion (chest tightness, nausea — rate-dependent). Effects last 1-3 days.

Week 1-2 (SubQ)

Improved energy and mental clarity. Better sleep quality. SubQ injections can sting temporarily.

Week 3-6

Sustained energy improvement. Brain fog clearing. Exercise recovery enhanced. Skin quality improving.

Month 2-3

Cumulative anti-aging effects. Users report feeling 5-10 years younger in energy and cognitive function. Bloodwork may show improved inflammatory markers.

Common Stacks

MOTS-c

Mitochondrial Synergy

NAD+ fuels the electron transport chain while MOTS-c optimizes mitochondrial gene expression — complementary mitochondrial support

Epitalon

Longevity Stack

NAD+ restores cellular energy while Epitalon activates telomerase — two pillars of anti-aging

Resveratrol

Sirtuin Amplification

Resveratrol activates sirtuins that require NAD+ as a cofactor — synergistic anti-aging signaling

// Preparation

Reconstitution & Storage

For subcutaneous use: Reconstitute lyophilized NAD+ with bacteriostatic water per vendor instructions. Note: NAD+ injections can sting — some users mix with lidocaine or inject slowly.

For IV: Must be administered by healthcare professional. Typical IV drip takes 2-4 hours.

Oral precursors (NMN, NR) require no reconstitution.

Storage: Lyophilized: -20°C to 2-8°C. Reconstituted: 2-8°C, use within 7-14 days. Protect from light.

Side Effects & Safety

Potential Side Effects

  • ! Injection site stinging/burning (SubQ — common and temporary)
  • ! Nausea during IV infusion (rate-dependent)
  • ! Chest tightness during IV (reduce drip rate)
  • ! Flushing
