In this concise monologue, the speaker introduces humanin, a small mitochondrial-derived peptide that acts as a molecular first responder. Humanin protects cells from oxidative damage by blocking pro‑death signals and activating pro‑survival pathways. The speaker notes that humanin levels naturally decline with age, drawing a parallel to the well‑known age‑related drop in NAD+. Research is highlighted showing that higher circulating humanin is associated with increased longevity, and that experimental studies have linked elevated humanin to neuroprotective effects, particularly in models of Alzheimer’s disease.

All right, humanin. This is another mitochondrial-derived peptide. It's made by your body. It's a very small peptide that acts like a molecular first responder. Ew. It protects against oxidative damage by blocking pro-death signals and activating pro-survival pathways. Levels of humanin drop as we age, kind of like NAD+. Basically, research is showing that higher humanin levels are correlated with longevity. There's been some amazing studies that have looked at cumin levels and neuroprotection, especially in Alzheimer's disease.
