Oxidative Stress

Oxidative stress is an imbalance between free radical production and antioxidant defenses, causing cellular damage associated with aging and disease.

Detailed Explanation

Oxidative stress damages DNA, proteins, and lipids. Several peptides counteract it: SS-31 reduces mitochondrial ROS production by protecting cardiolipin. DSIP upregulates antioxidant enzymes. Epitalon enhances DNA repair. GHK-Cu upregulates antioxidant gene expression. MOTS-c and Humanin provide cytoprotection through metabolic and anti-apoptotic signaling.
