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.

Aging &amp; Longevity

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. 

Immunity

Model: 8-month-old female Swiss mice
Dosage: 200 µL of aged-derived fecal suspension administered orally three days per week for two weeks

New Study: Transferring Gut Microbes from Old to Adult Mice Shortens Lifespan

Spanish scientists unveil data showing that transferring fecal microbes from old to adult mice increases biological age and shortens lifespan.

Participants: Older adults (ages 60 to 80) with mild cognitive impairment 
Dosage: 320 mg/day of anthocyanin capsules for 24 weeks

Anthocyanin, a compound found in berries, reduces inflammation and heart disease markers in older adults at risk for dementia.

Cardiovascular

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.
