MOTS-c, simplified.
Also called Mitochondrial peptide
Early researchA peptide made by your mitochondria, the power plants in your cells, that acts a bit like exercise in a molecule.
- Size
- 16 amino acids
- How it is taken
- Injection
- Status
- Research compound, under FDA review
What is it?
Most of your DNA sits in the cell’s nucleus, but mitochondria have their own. MOTS-c is coded there and helps cells handle sugar and energy.
What studies show
- In animalsIn mice, it improved insulin sensitivity, prevented diet-related weight gain and boosted exercise capacity.
- In peoplePeople’s natural levels rise with exercise and fall with age. Direct trials in people are very early.
What we don’t know yet
- Whether taking it does anything in people.
Side effects and cautions
- Very little human safety data.
Is it legal?
Not FDA-approved. Reviewed by an FDA advisory committee in July 2026 for obesity and osteoporosis.
