Model: C57BL/6 mice
Dosage: 500 mg/kg/day of SRN-901 via oral gavage for six days per week starting at 18 months of age; 14.4 ppm of rapamycin mixed in food starting at 18 months of age; 300 mg/kg/day of NMN via oral gavage for six days per week starting at 18 months of age; and 300 mg/kg/day of NR via oral gavage for six days per week starting at 18 months of age

Seragon Publishes Record-Breaking SRN-901 Longevity Data, Demonstrating 33% Lifespan Extension in Mice

In a newly published mouse study, SRN-901 extended remaining lifespan by 33%, slowed frailty progression, and lowered tumor incidence.

Seragon’s SRN-901 extended the remaining lifespan of adult mice by 33%, attenuated frailty progression by 70%, and reduced tumor incidence by 30.53%, according to a newly published preclinical study.

Participants: Healthy adults 
Dosage: An escalating dose of niacin (250-1000 mg/day) for 16 weeks

Finnish scientists used a new measurement system to detect low NAD+ levels in blood samples from people with a range of age-related conditions, but not in healthy older individuals.

Model: Male 16-month-old C57BL/6 mice 
Dosage: Intraperitoneal injection of 20 mg/kg/day of inosine for 4 weeks

Inosine Supplment Combats New Driver of Aging 

Scientists discover that inosine—a type of molecule called a purine nucleoside—alleviates multiple-organ aging in mice, and restores the oxygen delivery capacity of red blood cells.

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.
