Model: Young acquired niacin dependency (ANDY) mice. 
Dosage: 30 mg/kg/day of niacin

Mice engineered to have low body-wide NAD+ levels exhibit a shortened lifespan and widespread physical decline, which is largely reversed with the NAD+ booster niacin. 

NAD+ (nicotinamide adenine dinucleotide) levels were lower among older adults with frailty—an age-related condition associated with increased vulnerability to disability, disease, and death.

Aging Clocks Applied to Human Trial Data Support AI-Designed Drug Lowering Age

Six proteomics-based aging clocks (age assessments from large-scale analyses of proteins) agreed that patients treated with the AI-designed drug rentosertib appeared younger.

The AI-designed drug rentosertib was shown to lower biological age across six aging clocks in patients with idiopathic pulmonary fibrosis.

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.
