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).

How to Slow Aging: 7 Tips from a Danish Aging Expert

Danish aging expert Morten Scheibye-Knudsen shares seven ways to slow aging, including taking NR (nicotinamide riboside) and the diabetes medication metformin.

Danish aging expert Morten Scheibye-Knudsen does things like taking NR and metformin to slow his biological aging

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.

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.

Japanese scientists have found that reducing NAD+ (nicotinamide adenine dinucleotide) transport into mitochondria within the fat tissue of mice induces metabolic dysregulation and obesity.
