What is MOTS-c?

MOTS-c is a mitochondrial peptide composed of 16 amino acids, discovered in 2015 during advanced research on mitochondria. It is naturally produced by the human body and plays a significant role in energy regulation, physical stress management, and metabolism control.

In recent years, MOTS-c has attracted growing scientific interest for its potential to aid in fat loss, improve insulin sensitivity, and maintain energy levels during periods of calorie restriction or intense exercise. It is also being studied for its potential role in slowing certain aging-related processes and supporting overall vitality.

Although clinical studies in humans are still limited, many reports indicate positive effects such as more stable energy levels, reduced appetite, and faster recovery after physical exertion.

Important precautions

• Always start with low doses

• Do not exceed 8 consecutive weeks of use.

• Take breaks of 2–4 weeks between cycles.

• Discontinue use if you experience marked fatigue, cognitive difficulties, or persistent symptoms.

Note: MOTS-c may affect folate (5-MTHF) metabolism. Prolonged use may reduce intracellular folate levels, with a possible increase in oxidative stress and homocysteine. Adequate supplementation may be considered.

How MOTS-c works (mechanism of action)

MOTS-c acts directly on mitochondria, the "powerhouses" of cells, improving their efficiency and adaptive capacity.

Main mechanisms:

🔋 AMPK activation

Stimulates the main cellular energy sensor:

• Increases glucose uptake into cells

• Promotes fat burning

• Maintains energy production even under stress

🧬 Modulation of the folate cycle

• Improves nucleotide synthesis

• Promotes cell repair

• Protects DNA from oxidative stress

⚙️ Mitochondrial biogenesis

• Stimulates the formation of new mitochondria

• Increases endurance, recovery, and energy utilization

🔥 Reduction of inflammation

• Reduces pro-inflammatory cytokines (TNF-α, IL-6, IL-1β)

• Increases anti-inflammatory mediators (IL-10, TGF-β)

🧠 Adaptive genetic regulation

• Modulates gene expression in response to metabolic stress

• Improves cellular energy efficiency

Key scientific evidence

• Nature Communications (2021): improvement of endurance and muscle function in elderly mice

• Study 2022: restoration of mitochondrial function and increased longevity (+10%)

• Diabetes & Metabolism Journal (2023): Reduced MOTS-c levels in patients with type 1 diabetes

• ESPE: lower plasma levels of MOTS-c in obese children

To date, there have been no direct clinical trials on humans. However, numerous observational studies show a correlation between low MOTS-c levels, obesity, diabetes, and aging.
