What research findings exist for MOTS-C regarding metabolism, insulin sensitivity, and exercise performance?
MOTS-c enhances muscle mitochondrial bioenergetic performance and reduces reactive oxygen species-related damage, acting via PGC-1α and AMPK. Other studies report that MOTS-c increases exercise capacity in mice of various ages and regulates skeletal muscle metabolism.[1] ↗ [2] ↗
Currently, 3 original studies related to the theme of this page have been selected. The number of studies includes different designs, populations, or preparations, not commercial clinical efficacy ratings. This page is a usage-oriented positive data selection, not a systematic review or dosing recommendation. Historical studies, combination preparations, and special models are all separately indicated.
Comparison of study design and results
Results from different populations, species, materials, or follow-up times cannot be directly combined. The table below is a comparative summary of published data, not new experimental data.
| Literature | Study subjects and design | Observation and discovery | Scope of Explanation |
|---|---|---|---|
| 2026 · PMID 41520850 | Transgenic mouse administration and skeletal muscle mitochondrial experiments; also observed in human exercise | MOTS-c enhances muscle mitochondrial bioenergetic performance and reduces reactive oxygen species-related damage, acting via PGC-1α and AMPK. | Mainly mechanism and animal indicators; does not prove weight loss or exercise efficacy in humans. |
| 2021 · PMID 33473109 | Administration to mice of different ages; others observed endogenous levels of exercise in humans. | MOTS-c increases exercise capacity in mice of various ages and regulates skeletal muscle metabolism. | The human body is an endogenous expression induced by exercise and cannot be stated as having improved exercise performance through human injection. |
| 2015 · PMID 25738459 | Mouse administration and cellular mechanism; 2015 historical research | MOTS-c prevents high-fat diet–related obesity and insulin resistance in mice, directly corresponding to metabolic research. | No. Not clinical evidence for human weight loss; older studies, do not claim the latest progress. |

Does human exercise observation with MOTS-C equal effective human administration?＋
Not equal. In relevant studies, part of the human observation involved exercise-induced endogenous MOTS-c; evidence for improving exercise capacity comes from mice, and the two cannot be combined to claim ‘effective injection in humans’.[2] ↗
MOTS-C—these conclusions apply to which study populations?＋
Transgenic mouse administration and skeletal muscle mitochondrial experiments; also observed in human exercise; administration in mice of different ages; additional human exercise endogenous level observation; mouse administration and cellular mechanisms; 2015 historical study.
