<p>Model: Chronically stressed mice </p>
<p>Dosage: 9 mg/kg/day of L-serine, or 5 mg/kg/day of dasatinib combined with 50 mg/kg/day of quercetin </p>


Supplementing chronically stressed mice with L-serine, an amino acid, counters signs of anxiety and diabetes while diverting age-promoting senescent cells within the brain’s fear center.

Dasatinib and Quercetin Delay Early-Onset Disc Degeneration in Mice

Researchers find that clearing senescent cells preserves disc structure and slows early-onset disc degeneration in mice.


Top Evidence-Based Interventions to Lower Biological Age

Epigenetic aging clocks estimate biological age based on DNA molecular tagging patterns, and interventions like semaglutide and ketamine reduce these estimates in humans.

(The principal investigator behind the review on interventions that influence biological age, Dr. David Sinclair | The Society of the Four Arts)

As reviewed in this article, epigenetic aging clocks have estimated the effects of pharmaceutical interventions, lifestyle habits, supplements, and clinical interventions on biological age.

<p>Model: 11-month-old male C57BL/6J mice </p>
<p>Dosage: 30 mg/kg/day of NTX-748 (based on a small molecule called 78c) for 4 months, administered orally</p>


Blocking NAD+ Breakdown Improves Cognitive and Physical Performance

Buck Institute scientists find that blocking the CD38 enzyme, which elevates NAD+ (nicotinamide adenine dinucleotide), counteracts age-related cognitive and physical decline in mice.
