What it does

Also called elamipretide. It travels into the mitochondria and binds to cardiolipin, a fat that keeps the energy-producing machinery folded correctly. Think of it as tuning up the cell's power plants. What people look into it for: • Chronic fatigue and low energy tied to mitochondrial function • Heart and skeletal muscle performance • Recovery in older adults or after illness • Reducing oxidative stress and supporting healthy ageing It has been through real clinical trials for rare mitochondrial diseases, with mixed but promising results.

Mechanism

Binds cardiolipin on the inner mitochondrial membrane, improving electron transport efficiency.
