Increasing evidence indicates that alpha-ketoglutarate (AKG), a key metabolite in the tricarboxylic acid (TCA) cycle, can extend lifespan and healthspan across various animal models, raising interest in its potential neuroprotective effects in age-related disorders such as AD. Our previous research found that dietary supplementation with calcium...
