MOTS-c vs Carnosine
Side-by-side comparison of key properties, dosing, and research.
- Summary
- MOTS-c is a mitochondria-derived peptide (MDP) encoded within the mitochondrial genome. It acts as a metabolic regulator, improving insulin sensitivity, enhancing exercise capacity, and counteracting age-related metabolic decline. It is often called a 'mitochondrial hormone.'
- Carnosine is an endogenous dipeptide (beta-alanine + histidine) found in high concentrations in muscle and brain. It is a potent anti-aging molecule with broad spectrum antioxidant, anti-glycation, anti-carbonylation, and metal chelating properties, making it one of the most protective naturally occurring dipeptides.
- Half-Life
- Estimated 1–2 hours
- ~1.5 minutes (rapidly hydrolyzed to beta-alanine and histidine by carnosinase in blood; tissue levels maintained via constant synthesis)
