MOTS-c
Mitochondrial Open Reading Frame of the 12S rRNA Type-c
MOTS-c is a peptide produced by your mitochondria.
Noticed in days · Full benefit in weeks
Week 1-2
Improved blood sugar response is commonly the first sign. Energy may improve.
Week 2-4
Exercise capacity typically increases. Insulin sensitivity typically continues to improve.
Week 4-8
Sustained metabolic benefits are commonly reported. Body composition may start shifting.
Week 8-12
Full mitochondrial benefits typically reached. The body typically handles energy more flexibly, switching between fuel sources more easily.
MOTS-c is a peptide produced by your mitochondria. It acts as a hormone-like signal that helps regulate your metabolism, enhance insulin sensitivity, and promote longevity. MOTS-c works through a key energy-sensing pathway (AMPK) and can move into cell nuclei during stress to activate protective genes.
How it works
MOTS-c activates AMPK, your body's master energy sensor, which triggers a cascade of metabolic improvements: better blood sugar regulation, increased fat burning, and improved mitochondrial efficiency. When your cells are under metabolic stress, MOTS-c moves into the nucleus and activates stress-protection genes that boost antioxidant defenses and help cells adapt. This is why it shows benefits for both metabolic health and exercise performance.
Key benefits
What early research points to:
- ·Improves insulin sensitivity and blood sugar regulation
- ·Activates AMPK, your body's master energy sensor
- ·Supports mitochondrial health and energy production
- ·Enhances exercise performance and recovery
- ·Potential longevity and anti-aging benefits
