MOTS-c (Mitochondrial-derived peptide) is a unique peptide that is often described as an "exercise mimetic" because it replicates many of the metabolic benefits of physical activity at a cellular level. It functions primarily as a metabolic regulator by activating the AMPK pathway, a master switch for cellular energy. The core benefits include significantly improving insulin sensitivity and glucose utilization in muscle cells, which helps the body better manage blood sugar and combat insulin resistance. Furthermore, MOTS-c enhances fat oxidation, promoting the efficient use of stored fat for energy, and it is studied for its potential to improve physical endurance, muscle function, and overall longevity by supporting mitochondrial health and cellular resilience against metabolic stress.
