Model: Chronically stressed mice 
Dosage: 9 mg/kg/day of L-serine, or 5 mg/kg/day of dasatinib combined with 50 mg/kg/day of quercetin

Supplementing chronically stressed mice with L-serine, an amino acid, counters signs of anxiety and diabetes while diverting age-promoting senescent cells within the brain’s fear center.

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

The Anti-Aging Debate Everyone’s Talking About: Inside Bryan Johnson’s Jubilee Showdown

Bryan Johnson debates 20 skeptics on anti-aging in Jubilee’s viral episode and challenges assumptions about lifespan, science, and the future of human health.


Model: Young C57BL/6J mice fed a high protein (56% of daily calories) diet for 20 weeks 
Dosage: Injection with either 400 mg/kg of NMN or 20 mg/kg of 78c for 4 weeks

High protein intake improves the body composition of aged mice, but it lowers NAD+ (nicotinamide adenine dinucleotide) levels and promotes metabolic aging.
