Longevity science has advanced dramatically. We now understand key biological processes that drive aging—and strategies to influence them. The goal isn't just more years, but more healthy years.
The Hallmarks of Aging
Researchers have identified nine hallmarks including: genomic instability, telomere attrition, cellular senescence, and mitochondrial dysfunction. Many interventions target these processes.
Evidence-Based Longevity Strategies
Caloric Restriction / Time-Restricted Eating
Caloric restriction extends lifespan in every organism tested. Intermittent fasting may provide similar benefits through autophagy activation.
Exercise
The single most proven longevity intervention. Both cardio and strength training reduce all-cause mortality significantly.
Sleep Optimization
Poor sleep accelerates biological aging. Prioritize 7-9 hours of quality sleep.
Longevity Nutrients
NAD+ Precursors (NMN, NR)
NAD+ declines with age, impairing cellular energy and repair. Precursors can boost levels. Dose: 250-500mg NMN or NR.
Resveratrol
Activates sirtuins (longevity genes). Take with fat for absorption. Dose: 250-500mg.
Omega-3s
Higher omega-3 levels correlate with slower telomere shortening.
Vitamin D
Low levels linked to accelerated aging and disease.
Magnesium
Involved in DNA repair and hundreds of metabolic processes.
Lifestyle Factors
- Maintain muscle mass (sarcopenia is a major aging factor)
- Manage chronic stress (accelerates cellular aging)
- Stay socially connected (isolation shortens lifespan)
- Challenge your brain (cognitive reserve matters)
