Model: SAMP8 mice 
Dosage: ~25 mg/kg/day of PQQ or PQI administered in food

Supplementing with the antioxidant pyrroloquinoline quinone (PQQ) modestly extends the lifespan of age-accelerated mice while improving their strength.

Top Evidence-Based Interventions to Lower Biological Age

Epigenetic aging clocks estimate biological age based on DNA molecular tagging patterns, and interventions like semaglutide and ketamine reduce these estimates in humans.

(The principal investigator behind the review on interventions that influence biological age, Dr. David Sinclair | The Society of the Four Arts)

As reviewed in this article, epigenetic aging clocks have estimated the effects of pharmaceutical interventions, lifestyle habits, supplements, and clinical interventions on biological age.

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

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

Participants: Older adults (ages 60 to 80) with mild cognitive impairment 
Dosage: 320 mg/day of anthocyanin capsules for 24 weeks

Anthocyanin, a compound found in berries, reduces inflammation and heart disease markers in older adults at risk for dementia.
