Abstract

MOTS-c (Mitochondrial Open Reading Frame of the 12S rRNA-c) is a recently discovered mitochondrial-derived peptide consisting of 16 amino acids. It functions as a regulator of metabolism, insulin sensitivity, and cellular stress response. Unlike most peptides encoded in nuclear DNA, MOTS-c originates from mitochondrial DNA (mtDNA), making it a unique player in aging, exercise physiology, and metabolic health.

Research suggests that MOTS-c may help with weight management, insulin regulation, exercise performance, and longevity by directly influencing mitochondrial and nuclear pathways.

How MOTS-c Works (Layman’s Terms)

• Metabolic Regulator: MOTS-c helps cells use glucose and fat more efficiently for energy.
• Insulin Sensitivity: Improves how the body responds to insulin, potentially helping in prediabetes and type 2 diabetes.
• Exercise Mimetic: Activates AMPK (AMP-activated protein kinase), mimicking exercise at the cellular level.
• Longevity Pathways: Interacts with nuclear genes involved in aging and cellular repair.
• Stress Resistance: Protects cells from oxidative stress and metabolic dysfunction.
