Model: Middle-aged cynomolgus monkeys
Dosage: 30 mg/kg/day of vitamin C, orally administered for 40 months

Vitamin C Alleviates Aging in Monkeys

Vitamin C improves brain volume and connectivity, reduces biological age, enhances metabolic health, and alleviates underlying aging drivers, such as cellular senescence, in older monkeys. 

Advanced Alzheimer’s Can Be Reversed With NAD+ Restoration, Study Shows in Mice

Researchers at Case Western Reserve University have shown that late-stage neurodegeneration may be biologically reversible, at least in the right conditions, in mice.
