MOTS-C 40mg

MOTS-c (Mitochondrial Open Reading Frame of the 12S rRNA Type-c) is a mitochondrial-derived peptide (MDP) that has gained significant attention in metabolic and aging research. Unlike most peptides, which are encoded by nuclear DNA, MOTS-c is encoded by the mitochondrial genome. This unique origin makes it one of the few known signaling molecules produced directly by mitochondria.

Research background: MOTS-c research profile · AOD-9604 vs MOTS-C

MOTS-c is a 16-amino acid peptide encoded within the 12S ribosomal RNA (12S rRNA) region of mitochondrial DNA. It functions as a metabolic regulator by helping cells adapt to stress and maintain energy balance. Under conditions such as oxidative stress, nutrient deprivation, or exercise, MOTS-c can move from the mitochondria into the nucleus, where it regulates the expression of genes involved in metabolism and cellular protection.

Researchers have found that MOTS-c activates AMP-activated protein kinase (AMPK), often called the body’s “master energy sensor.” Through AMPK activation, MOTS-c promotes glucose uptake, improves insulin sensitivity, increases fatty acid oxidation, and supports healthy mitochondrial function. Because of these effects, it has become an important research target for obesity, type 2 diabetes, healthy aging, and metabolic disorders.

Brief History of MOTS-c

The discovery of MOTS-c marked an important milestone in mitochondrial biology. In 2015, researchers led by Changhan Lee at the University of Southern California first identified MOTS-c and described its role in metabolic regulation. Their groundbreaking study demonstrated that mitochondria produce signaling peptides capable of influencing metabolism throughout the body. This discovery challenged the long-standing belief that mitochondrial DNA only encoded proteins required for energy production.

Following its discovery, researchers around the world began investigating the biological functions of MOTS-c. Early animal studies showed that MOTS-c improved insulin sensitivity, prevented diet-induced obesity, and enhanced glucose metabolism. Later research revealed that circulating MOTS-c levels decline with age, suggesting that it may play an important role in healthy aging and age-related diseases.

More recent studies have also identified MOTS-c as an exercise-induced peptide. Exercise naturally increases MOTS-c levels, and experimental studies suggest that the peptide can activate many of the same metabolic pathways triggered by physical activity. This has led researchers to investigate MOTS-c as a potential exercise mimetic in metabolic and aging research.

Research and Scientific Evidence

MOTS-c remains an active area of preclinical and early clinical research. Most evidence currently comes from laboratory experiments and animal studies, while human research is still limited.

Some important research findings include:

• The original 2015 Cell Metabolism study demonstrated that MOTS-c improved metabolic homeostasis and reduced obesity and insulin resistance in mice.
• Experimental studies have shown that MOTS-c activates AMPK, leading to increased glucose utilization, improved insulin sensitivity, and enhanced fat metabolism.
• A 2021 Nature Communications study found that MOTS-c is released during exercise and improved physical performance and muscle function in aged mice, suggesting a role in healthy aging.
• Human observational studies have reported that circulating MOTS-c levels are generally lower in older adults and individuals with obesity or type 2 diabetes, indicating a possible relationship with metabolic health.
• As of 2026, no large completed Phase III clinical trials have confirmed therapeutic benefits in humans. Human clinical research is still ongoing, and additional studies are needed to establish long-term safety and effectiveness.

Why MOTS-c Is Important

MOTS-c has opened a new field of research by showing that mitochondria produce signaling peptides that regulate whole-body metabolism. It is one of the first mitochondrial-derived peptides shown to influence glucose metabolism, insulin sensitivity, skeletal muscle function, and cellular stress responses. Today, MOTS-c is widely studied for its potential role in metabolic diseases, obesity, exercise physiology, muscle health, and healthy aging. Although the early findings are promising, much of the evidence is still preclinical, and further human studies are required before definitive clinical conclusions can be made.
