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.

Aging &amp; Longevity

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.

New Study Shows Cranberry Extract Equivalent to Metformin in Fighting Aging

Fayoum University researchers found that cranberry polyphenols improve metabolic markers, cognition, and oxidative stress to the same degree as the drug metformin.

A new study suggests cranberry extract has effects against aging that rival metformin.

Dark Chocolate Compound Linked to Slower Aging, Study Finds

Elevated circulating theobromine—derived from cocoa—was associated with a slower pace of aging, according to two assessments.
