What is MOTS-c?
MOTS-c (Mitochondrial Open Reading Frame of the 12S rRNA Type-c) is a 16-amino-acid peptide encoded by mitochondrial DNA. This makes it unique — most peptides in the body are encoded by nuclear DNA.
It was discovered in 2015 by a team at the University of Southern California, led by Dr. Changhan David Lee. The discovery generated significant interest because it showed that mitochondria do not merely produce energy but actively communicate with the rest of the cell through signaling molecules.
MOTS-c is regarded as a 'mitokine' — a molecule produced by the mitochondria that influences metabolism throughout the entire organism.
How does it act in the body?
MOTS-c activates the AMPK pathway — the cell's primary energy sensor. When AMPK is activated, cells switch from storing energy to expending it. This includes increased oxidation of fatty acids and improved glucose uptake.
In preclinical models, MOTS-c has demonstrated the ability to improve insulin sensitivity and prevent the accumulation of fat tissue in mice on a high-fat diet.
Researchers suggest that natural MOTS-c levels in the body decline with age, which may be linked to the age-related slowdown of metabolism.
What does the research say?
A publication in Cell Metabolism (2015) was the first to describe MOTS-c and demonstrated its effect on glucose metabolism in mice. Those receiving MOTS-c showed significantly better glucose tolerance.
A study in Nature Communications (2020) revealed that MOTS-c translocates to the cell nucleus under metabolic stress, where it directly regulates gene expression — a mechanism not seen in other mitochondrial peptides.
A 2021 study in the Journal of Cachexia, Sarcopenia and Muscle showed that MOTS-c can improve physical capacity in mice — increased endurance during treadmill running.
5 reasons why MOTS-c is among the most studied new peptides
1. The first mitochondrial peptide — The discovery of MOTS-c changed our understanding of mitochondria. They are not merely 'power plants,' but active signaling hubs.
2. AMPK activation — AMPK is one of the most studied targets for metabolic modulation. MOTS-c activates it through a natural pathway, without stimulants.
3. Potential for improved endurance — Preclinical data indicate increased physical endurance, which attracts interest from sports science.
4. Age-related decline — Natural MOTS-c levels decrease with age, which makes it of interest for research in the field of healthy aging.
5. Synergy with other approaches — In research settings, MOTS-c is being studied in combination with 10-Amino-1MQ and GLP-1 agonists for potential complementary effects.

Frequently Asked Questions
What is the difference between MOTS-c and ordinary metabolic supplements? — MOTS-c is an endogenous peptide (the body produces it naturally), encoded by mitochondrial DNA. It acts through AMPK activation at the cellular level, rather than through stimulants such as caffeine.
Do levels decrease with age? — Yes, preclinical data show that mitochondrial MOTS-c levels decline with advancing age, which correlates with reduced metabolic efficiency.
How is it stored? — At +2°C to +8°C (refrigerator). Keep away from direct sunlight. Shelf life: see label.
