Mechanism of Action Comparison
How MOTS-c Works
MOTS-c MOTS-c is a peptide encoded in mitochondrial DNA studied for improving insulin sensitivity, boosting exercise performance, and protecting against the metabolic decline that comes with aging.
Regulates mitochondrial function and AMPK. Enhances glucose uptake and fatty acid oxidation, improves insulin sensitivity, and protects against age-related metabolic decline.
How NAD+ Works
NAD+ NAD+ is a coenzyme essential for cellular energy and DNA repair that declines sharply with age, studied for restoring mitochondrial function and supporting longevity pathways.
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 Mechanistic Difference
MOTS-c operates as a mitochondrial peptide, while NAD+ functions as a longevity — these are fundamentally different pharmacological approaches.
