Aging &amp; Longevity

Model: Two-month-old male C57BL/6J mice fed a high-fat diet to induce obesity 
Dosage: 400 mg/kg/day of NR for eight weeks

Scientists find that NR (nicotinamide riboside) supplementation preserves brown fat tissue in mice, reducing their body weight and maintaining the health of their mitochondria.

Diabetes &amp; Obesity

Model: C57BL/6N male mice 
Dosage: AIN-93 M diet with 0.025% (15 mg/kg per day) niclosamide for the Old + NL group or 0.050% (30 mg/kg per day) niclosamide for the Old + NH group, starting at 12 months of age to 21 months of age
