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.

Participants: Healthy, overweight older adults 
Dosage: 6 mg/day of spermidine supplemented orally for 13 weeks

Oxford scientists find that spermidine, a naturally occurring molecule that declines with age, rejuvenates aging immune cells and improves vaccine protection in older adults. 


Study conducted at the University of Oxford in England.

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).

Participants: Sedentary older adults 
Dosage: 6 mg/week of rapamycin

In older adults, the FDA-approved drug rapamycin, associated with prolonging lifespan, blunts improvements in physical performance.

What Is Mosaic Aging? How Organs Age at Different Rates

A new framework proposes that the patchwork nature of aging, where different organs deteriorate at different speeds, may hold the key to understanding the ultimate cause of death.

A new framework proposes that aging occurs unevenly in cells, tissues, and organs, and that targeting the fastest-aging tissues may extend lifespan.
