MOTS-c
Also known as: Mitochondrial Open Reading Frame of the 12S rRNA-c, Mitochondrial-Derived Peptide, Exercise Mimetic Peptide
MOTS-c is a 16-amino-acid peptide encoded within the mitochondrial genome (12S rRNA gene), making it one of the few known mitochondrial-derived peptides with systemic signaling functions. Discovered in 2015 by Dr. Changhan Lee's lab at USC, MOTS-c activates the AMPK pathway — the same cellular energy sensor activated by exercise — and has been called an "exercise mimetic" for its ability to reproduce many of the metabolic benefits of physical activity. Research has demonstrated improvements in insulin sensitivity, glucose metabolism, and exercise capacity. MOTS-c levels decline with age, correlating with metabolic dysfunction and reduced physical performance. Supplementation aims to restore youthful metabolic signaling.
Growing body of research
Well-tolerated with minimal side effects
How It Works
MOTS-c is encoded by the mitochondrial 12S rRNA gene and acts as a retrograde signaling molecule. It activates AMPK, the master cellular energy sensor, promoting glucose uptake, fatty acid oxidation, and mitochondrial biogenesis. It also translocates to the nucleus under metabolic stress to regulate gene expression related to antioxidant defense and metabolism.

Dr. Taylor's 2 Cents
“MOTS-c is the peptide equivalent of exercise in a bottle — and I don't say that lightly. It activates the exact same AMPK pathway that exercise does, which means improved insulin sensitivity, better glucose metabolism, and enhanced mitochondrial function. I use it for patients who are metabolically compromised or physically limited and need to jumpstart their cellular metabolism. It's not a replacement for exercise, but it can amplify the benefits and help patients who are starting from a deficit.”
