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


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

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.
