Humanin is a 24–amino acid peptide naturally produced by the mitochondria—the cell’s energy centers—and discovered for its protective effects on neurons. Research shows that Humanin helps shield cells from oxidative stress, inflammation, and programmed cell death. It interacts with multiple cellular receptors and signaling pathways that regulate metabolism, stress resistance, and survival. By improving mitochondrial function and activating repair mechanisms, Humanin supports healthy energy production and cellular resilience.
Studies have linked higher Humanin levels to improved cardiovascular, metabolic, and neuroprotective outcomes, while declining levels are associated with aging and chronic disease. Humanin has been shown to protect brain cells from Alzheimer’s-related damage, enhance insulin sensitivity, and promote overall metabolic balance. Because of these broad cytoprotective and anti-aging effects, Humanin is being studied as a potential therapeutic molecule to improve health span and delay age-related decline.
