Participants: Healthy, overweight older adults 
Dosage: 6 mg/day of spermidine supplemented orally for 13 weeks

Oxford scientists find that spermidine, a naturally occurring molecule that declines with age, rejuvenates aging immune cells and improves vaccine protection in older adults. 


Study conducted at the University of Oxford in England. 

Immunity

Participants: Prefrail older adults
Dosage: 50 mg/day of losartan for at least 8 weeks

Losartan, a common blood pressure medication, increases the survival rate of mice and improves the metabolic outlook of pre-frail older adults.

Brain &amp; Neurons

Model: Naturally aged 24-month-old C57BL/6 mice 
Dose: 0.1 mg/kg/day of folic acid administered orally for 12 months

Supplementation with vitamin B9, also known as folic acid or folate, prevents cellular senescence and slows vascular aging in naturally aged mice.
