Model: Old (17- to 19-month-old) C57BL6 mice 
Dosage: 14 mg/mg/day of rapamycin in food for 5 months

A purported longevity drug, rapamycin, alters immune cells associated with cancer and reduces brain inflammation in mice. 

Immunity

Model: Old male mice
Dosage: 100 mg/kg/day of ALA administered in drinking water

Restoring the naturally occurring antioxidant, alpha-lipoic acid (ALA), to the gut wall rejuvenates stem cells and counters age-related gut degeneration in mice and human models.

Top Evidence-Based Interventions to Lower Biological Age

Epigenetic aging clocks estimate biological age based on DNA molecular tagging patterns, and interventions like semaglutide and ketamine reduce these estimates in humans.

As reviewed in this article, epigenetic aging clocks have estimated the effects of pharmaceutical interventions, lifestyle habits, supplements, and clinical interventions on biological age.

Peter Fedichev’s Physics-Based Approach to Aging: A New Longevity Framework

Peter Fedichev describes aging as a three-variable system of stress (from physical, psychological, or molecular stressors), noise (small random biological fluctuations), and damage (cumulative wear-and-tear).

Peter Fedichev has proposed a physics-based framework for aging, encompassing stress, noise (small random biological fluctuations), and damage (cumulative wear-and-tear).
