NAD+ peptides boost cellular NAD+ (nicotinamide adenine dinucleotide) levels to enhance energy production, improve mitochondrial function, and support anti-aging processes. Unlike oral NAD+ supplements with poor absorption, peptide-based NAD+ boosters deliver measurable results.

This guide covers everything about NAD+ peptides - what they are, how they work, proper dosing protocols, expected benefits, comparison to NAD+ IV therapy, stacking strategies, and safety considerations.

Understanding NAD+ and why it matters

NAD+ is critical for cellular energy and longevity.

What is NAD+?

NAD+ (Nicotinamide Adenine Dinucleotide): Essential coenzyme found in every cell

Functions:

• Powers mitochondria (cellular energy production)

• DNA repair mechanisms

• Sirtuin activation (longevity genes)

• Metabolic regulation

• Cellular stress response

The problem: NAD+ levels decline 50% by age 40-50

Consequences of low NAD+:

• Reduced energy and fatigue

• Slower recovery

• Accelerated aging

• Impaired cognitive function

• Metabolic dysfunction

• Decreased cellular repair

Learn about how peptides work at the cellular level.

Why NAD+ declines with age

Natural age-related decline:

• Decreased production

• Increased consumption (more cellular stress)

• Reduced recycling efficiency

• Mitochondrial dysfunction

By age 50: NAD+ levels about half of age 20 levels

Impact: Everything from energy to recovery to longevity affected
