Model: Female Balb/c mice exposed to ultraviolet radiation 
Dosage: 2%, 5%, 7.5%, or 12.5% of nicotinamide (weight/volume) applied topically, once daily, five times per week

The NAD+ (nicotinamide adenine dinucleotide) precursor nicotinamide prevents skin aging, in part by targeting age-promoting senescent cells in mice. 


Model: Male Wistar rats 
Dosage: 1.5 g/kg/day of orally administered glycine for 5 months

Glycine, an amino acid shown to extend the lifespan of mice, moderately extends the lifespan of flies and counters brain and muscle degeneration in aged rats.

GlyNAC and Exercise for Age-Related Muscle Loss: Mechanisms and Clinical Evidence

Human trials report that GlyNAC and exercise regimens improve dysfunction of the cell’s powerhouses (mitochondria), inflammation, muscle strength, and cognition.

(Some GlyNAC tablets above the chemical structure of GlyNAC | Vitamin Retailer)

GlyNAC supplementation and exercise alleviate mitochondrial dysfunction, lower inflammation, increase muscle strength, and bolster cognition.

Model: Old male mice
Dosage: 100 mg/kg/day of ALA administered in drinking water

Restoring the naturally occurring antioxidant, alpha-lipoic acid (ALA), to the gut wall rejuvenates stem cells and counters age-related gut degeneration in mice and human models.
