MOTS-c
Mitochondrial ORF of the Twelve S rRNA Type-c
The exercise-mimicking peptide encoded in your mitochondrial DNA
MOTS-c is a mitochondrial-derived peptide that activates AMPK, the same pathway triggered by exercise. Research links it to improved metabolic function, insulin sensitivity, and exercise performance.

Overview
MOTS-c is a 16-amino-acid peptide encoded within the mitochondrial genome - one of only a handful of known mitochondrial-derived peptides (MDPs). Discovered in 2015 by Dr. Changhan Lee at USC, it is unique because it is encoded by mitochondrial DNA rather than nuclear DNA. MOTS-c activates AMPK (AMP-activated protein kinase), the same master metabolic switch that exercise triggers. This has led to its characterisation as an 'exercise mimetic' - a compound that produces some of the metabolic benefits of exercise at the cellular level. It is particularly interesting in the context of aging, as mitochondrial function declines with age.
⚙️How it works
MOTS-c activates AMPK, the cellular energy sensor that is normally triggered by exercise or caloric restriction. AMPK activation promotes glucose uptake, fatty acid oxidation, mitochondrial biogenesis, and autophagy. MOTS-c also regulates the folate-methionine cycle, affecting one-carbon metabolism and cellular methylation patterns. In animal studies, MOTS-c treatment improved insulin sensitivity, reduced fat accumulation, and enhanced exercise capacity in both young and old mice. Notably, endogenous MOTS-c levels decline with age and are higher in physically active individuals.

The exercise mimetic concept
MOTS-c is sometimes called an 'exercise in a peptide' - but this oversimplifies it. It activates AMPK, one of the key molecular pathways that exercise activates, but exercise triggers hundreds of molecular changes simultaneously. MOTS-c provides a subset of exercise's metabolic benefits (glucose uptake, fat oxidation, mitochondrial function) but doesn't replace the cardiovascular, musculoskeletal, and neurological benefits of actual physical activity. It's best thought of as a metabolic optimiser that complements exercise rather than replacing it.
