Participants: Older adults with elevated HbA1c
Dosage: Nicotinamide (250 mg), palmitoylethanolamide (600 mg), oleoylethanolamide (400 mg), and spermidine (8 mg)

In older adults, the combination of nicotinamide, palmitoylethanolamide (PEA), oleoylethanolamide (OEA), and spermidine counters cardiovascular and metabolic aging.

Andrew Huberman’s Updated Supplement Stack for 2026

Stanford neuroscientist Andrew Huberman’s updated supplement list includes the NAD+ precursor NMN, along with other compounds for sleep and cognitive performance.

Dr. Andrew Huberman’s new supplement stack for 2026 includes NMN, along with supplements supporting sleep, testosterone synthesis, and cognitive function.

Aging &amp; Longevity

Model: Female New Zealand white rabbits 
Dosage: 20 mg/kg of fisetin

Fisetin reduces susceptibility to a heart condition called atrial fibrillation (AF) and eliminates age-promoting senescent cells in aged rabbits.

Cardiovascular

Model: Young C57BL/6J mice fed a high protein (56% of daily calories) diet for 20 weeks 
Dosage: Injection with either 400 mg/kg of NMN or 20 mg/kg of 78c for 4 weeks

High protein intake improves the body composition of aged mice, but it lowers NAD+ (nicotinamide adenine dinucleotide) levels and promotes metabolic aging. 

Metabolism

Model: Male COX7RP transgenic mice with systemic overexpression of COX7RP, aged under standard laboratory conditions and compared with age-matched wild-type controls.
Dosage: Not applicable. COX7RP activity was increased via genetic overexpression rather than drug administration.

Boosting mitochondrial efficiency by increasing COX7RP activity extended lifespan in mice while improving energy production and reducing inflammation.
