Model: Male Sprague-Dawley rats 
Dosage: 400 mg/kg of magnesium L-theanine and 600 mg/kg of nicotinamide riboside administered orally for 40 days

Scientists find that treating rats with magnesium L-theanine and nicotinamide riboside (NR) counteracts stress-induced metabolic, gut, and liver aging.

Can Intermittent Fasting Slow Down Gut Aging? New Research Suggests So

A new study provides data suggesting compromised intestinal function with age and that fasting for short periods promotes intestinal regeneration and function in aged mice.

Alternate-day fasting, a form of intermittent fasting, reverses age-related intestinal barrier leakage in old mice.

The cutoff for vitamin B12 deficiency is too low, according to new findings showing that “normal” B12 levels are associated with neurological deficits in older adults.

Dose (oral): 5 mg/kg of dasatinib combined with 50 mg/kg of quercetin

Senolytics Restore Age-Related Heart-Brain Connection Loss

Treating old mice with two senolytics — compounds that remove senescent (dysfunctional) cells —  called dasatinib and quercetin prevents heart-brain connection loss and irregular heart rhythms.

New Study: Green Tea Molecule Extends Lifespan and Alleviates Fat Tissue Senescence

Epigallocatechin gallate (EGCG) supplementation substantially prolongs lifespan and suppresses senescence — an age-related, dysfunctional cellular state — in the fat tissue of mice.

EGCG supplementation over 18 months increases median lifespan by ~25% and significantly lowers fat tissue senescence in mice.
