Model: Male C57BL/6 mice given continuous alcohol for 4 weeks 
Dosage: 350 mg/kg/day of nicotinamide riboside chloride for 2 weeks

The NAD+ (nicotinamide adenine dinucleotide) precursor nicotinamide riboside chloride (NRC) counteracts neuronal damage caused by alcohol consumption in mice. 

Brain &amp; Neurons

Model: Aged mice (18 months old) underwent exploratory laparotomy under isoflurane anesthesia to induce POCD.
Dosage: Berberine was given by oral gavage at 100 mg/kg per day for 14 days after surgery.

Ancient Plant Compound Shows Promise for Protecting the Aging Brain 

Study shows berberine, a natural plant compound, protects memory in aging mice after surgery by reducing brain inflammation, stress, and cell damage.


University of California (UC) Berkeley scientists moderately extend the lifespan of old mice by giving them oxytocin (sometimes called the "love hormone") and a compound that inhibits inflammation.  

Aging &amp; Longevity

Chinese scientists have genetically engineered stem cells capable of rejuvenating the health, including the cognition, of aged macaques.
