Humanin Peptide Guide: Longevity, Mitochondrial Protection & How It Works
Humanin is a mitochondrial-derived peptide studied for its role in cellular protection, aging, metabolic health, and neuroprotection. Unlike traditional peptides, it originates within the mitochondria and is involved in protecting cells from stress, dysfunction, and degeneration.
In This Breakdown
What Is Humanin?
Type: Mitochondrial-derived peptide
Primary Role: Cellular protection + longevity
Key Function: Anti-apoptotic signaling
Category: Longevity / mitochondrial peptide
Humanin is encoded within mitochondrial DNA and plays a role in protecting cells from stress-induced damage, particularly in metabolic and neurological systems.
