Inner membrane targeting, not generic antioxidant therapy.
SS-31 (elamipretide) is a cell-permeable Szeto-Schiller tetrapeptide that concentrates in the inner mitochondrial membrane — studied for its ability to stabilize cardiolipin, support electron transport chain function, and reduce oxidative stress in cardiac, skeletal muscle, and neurodegeneration models.
It is not FDA-approved for medical use. Natura ships it as a batch-verified research pen so you can dial a consistent dose and read the lab paperwork before you open the box.
