Advances in longevity science are reshaping how aging is studied, with peptides and targeted supplements gaining increasing attention in research environments. Rather than addressing aging as a single process, these compounds are examined for their potential roles in cellular repair, metabolic efficiency, mitochondrial health, and inflammatory regulation key biological systems associated with lifespan and healthspan. This overview explores seven emerging longevity-focused strategies centered on peptides and supportive supplements that are frequently discussed in scientific literature. From compounds investigated for their influence on cellular signaling and tissue maintenance to supplements studied for oxidative balance and metabolic resilience, each entry reflects ongoing efforts to better understand age-related biological decline.
