Humanin vs MOTS-c
An educational, source-based comparison of Humanin and MOTS-c — how each peptide works, what it's researched for, and what to know before going deeper.
Mitochondrial-derived peptide studied for neuroprotection and metabolism.
A 24-amino-acid peptide encoded in mitochondrial DNA. Research suggests cytoprotective effects against Alzheimer's-related toxicity, improved insulin sensitivity, and modulation of apoptotic signaling.
- Neuroprotection (Alzheimer's models)
- Insulin sensitivity
- Cardiovascular protection in animal models
- • Early-stage research.
- • No approved therapeutic use.
A 16-amino-acid peptide encoded within the mitochondrial 12S rRNA gene. Research suggests it activates AMPK, enhances insulin sensitivity, and regulates nuclear gene expression in response to metabolic stress — positioning it as a candidate mitochondrial-nuclear signaling peptide.
- Insulin sensitivity
- Exercise capacity and mitochondrial biogenesis
- Age-related metabolic decline
- Obesity models
- • Early-stage research; no approved human therapeutic use.
- • Long-term effects unknown.
Trial-evidence rating
