Model: Male C57BL/6J (B6) mice (15 months old at the start of treatment)
Dosage: Approximately 5 mg/kg/day of S-1-propenyl-L-cysteine (S1PC) was administered orally for 8 months, from 15 to 23 months of age. S1PC was given in chow containing 0.0025% S1PC, with a second experiment using drinking water to confirm the findings.

Researchers found that a compound found in garlic supports healthier muscle aging by boosting cellular defenses linked to longevity and maintaining physical performance.

Japanese scientists have found that reducing NAD+ (nicotinamide adenine dinucleotide) transport into mitochondria within the fat tissue of mice induces metabolic dysregulation and obesity. 

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.

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.
