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.

How to Boost Mitochondrial Density and Quality for Longevity

Lifestyle hacks contrived to promote the tissue density and quality of mitochondria (the cell’s powerhouses) can aid in the efficient generation of cellular energy and reduce inflammation, thereby promoting longevity.

Exercise, nutritional support, and lifestyle hacks like cold exposure can all help mitigate mitochondrial dysfunction, a key hallmark of aging.

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.

Elevating the naturally occurring molecule NAD+ (nicotinamide adenine dinucleotide) improves memory and corrects gene-splicing patterns in a worm and a mouse model for dementia.
