What Is the Mitochondrial Stack?
The Mitochondrial Stack is a three-compound research protocol designed to address mitochondrial decline from three distinct angles simultaneously.
Mitochondria are the energy-producing organelles found in virtually every cell in the body. They generate ATP — the cellular currency that powers every biological process from muscle contraction to DNA repair. As we age, mitochondrial function declines across three key dimensions:
• Structure degrades — the inner mitochondrial membrane loses integrity, reducing the efficiency of ATP production
• Signaling weakens — the metabolic communication between mitochondria and the rest of the cell diminishes
• Fuel availability drops — NAD+ levels, the essential coenzyme mitochondria need to produce energy, decline by approximately 50% between ages 40 and 60
The Mitochondrial Stack addresses all three dimensions with a specific compound for each:
→ SS-31 — Structure. Protects and restores the inner mitochondrial membrane
→ MOTS-C — Signaling. Activates metabolic communication between mitochondria and cells
→ NAD+ — Fuel. Replenishes the coenzyme mitochondria need to produce ATP
Think of it this way: SS-31 fixes the engine. MOTS-C tells the engine how to run smarter. NAD+ fuels the engine with what it needs to run at all.
