Model: 20-month-old female C57BL/J mice 
Dosage: 10 nmol/kg/day of semaglutide

Semaglutide extends mouse lifespan and targets signs of aging, such as diminished NAD+, while mimicking the anti-aging effects of caloric restriction (consuming fewer calories). 


The study was led by Dr. Danica Chen (image: berkeley.edu). 

Aging &amp; Longevity

Model: C57BL/6J mice 
Dosage: Eating only within an 8-hour window and fasting for 16 hours (~20% caloric deficit may be required)

Restricting food intake for 16 hours a day improves the health of female mice and moderately prolongs the life of male mice.

NAD+ Ranked #2 Most Powerful Anti-Aging Agent

Based on current scientific evidence, Dutch researchers have ranked existing anti-aging interventions based on how likely they are to protect against DNA damage and aging.

DNA Repair

Participants: Healthy middle-aged to older adults (average age: ~53 years)
Dosage: 1,000 mg/day of urolithin A for 28 days

Supplementing healthy adults with urolithin A —a compound produced by our gut bacteria— counters signs of age-related immune system decline.

Johns Hopkins Research Review: Parkinson’s Drug Extends Multiple Species' Lifespan

L-deprenyl, a drug used to treat Parkinson’s disease and major depressive disorder, has been shown to modestly extend lifespan across species, from mice to rats to hamsters.

L-deprenyl, a drug prescribed to treat Parkinson’s disease and major depressive disorder, has been shown to modestly extend average lifespan across mammalian model organism species.
