An evidence-based exploration of cellular health, longevity research, and the biological processes that influence how we age.
Explore the FrameworkDecades of gerontology research have identified key biological pathways that influence aging. This framework organizes current scientific understanding into actionable domains.
As cells age, some enter a senescent state where they stop dividing but don't die. These "zombie cells" accumulate and may contribute to age-related decline. Research explores compounds that may help clear senescent cells.
NAD+ is essential for cellular energy and DNA repair. Levels decline ~50% by age 60. Studies examine whether NAD+ precursors (NMN, NR) can support cellular function in aging populations.
Cellular "housekeeping" that removes damaged proteins and organelles. Autophagy declines with age. Intermittent fasting and certain compounds may activate this cleaning process.
Protective caps on chromosomes that shorten with each cell division. When critically short, cells can't divide. Lifestyle factors like stress, sleep, and exercise influence telomere maintenance.
Cellular powerhouses that generate energy. Mitochondrial dysfunction accumulates with age. Exercise, caloric restriction, and specific nutrients may support mitochondrial health.
Your biological age can differ from chronological age based on DNA methylation patterns. Epigenetic clocks measure biological aging, and research explores interventions that may slow this process.
A selection of peer-reviewed research on aging biology and interventions that may influence healthspan
Long-term caloric restriction without malnutrition extends lifespan in multiple species and improves biomarkers of aging in primates and humans.
Removing senescent cells in aged mice delayed physical dysfunction and extended healthspan. Senolytics are now being studied in human trials.
Boosting NAD+ levels through supplementation improved muscle function, cognition, and metabolic markers in rodent models of aging.
Regular aerobic exercise increases BDNF (brain-derived neurotrophic factor), supports neurogenesis, and is associated with slower cognitive decline.
Adherence to Mediterranean dietary patterns is associated with reduced all-cause mortality and lower risk of age-related chronic diseases.
Strong social relationships are associated with 50% increased survival probability. Social isolation carries mortality risk comparable to smoking.
