A randomized trial, focused on twins over the age of 50, reports that a daily mix of protein and prebiotics improved performance on a sensitive memory test after 12 weeks.
Scientists have been mapping how <a href="http://www.familyzh.cn:53000/willy13t790820/3343598/wiki/The-Top-5-Natural-Nootropics-for-Improving-Focus-and-Mental-Clarity">The Genius Switch audio</a> gut microbiome communicates with the
brain through immune, neural, and hormonal routes, an interconnected axis that shapes cognition across
the lifespan. That big picture matters when we ask
whether feeding gut bacteria can sharpen memory in later life.
Lead researcher Mary Ni Lochlainn, King’€™s College London (KCL), and colleagues asked whether adding
a daily prebiotic to a modest protein supplement and
light resistance exercise could affect cognition in older twins.
The team enrolled 36 pairs, each aged 60 or older, and assigned one twin to
inulin plus fructooligosaccharides while the co-twin received a placebo, all under double
blind conditions. Everyone received the same branched
chain amino acid protein powder and simple at home strength moves.
The 12 week protocol ran remotely using video visits, online questionnaires, and posted kits for cognitive testing and stool samples.
