Inexpensive gut-friendly duo boosts memory and may guard against dementia, twin study finds
A randomized twin trial in adults 60+ found that a daily mix of protein plus prebiotic fructooligosaccharides improved memory on a sensitive PAL test after 12 weeks, with gut microbiota shifts (notably higher Bifidobacterium). No muscle-strength gains were observed. While the findings suggest benefits for brain health and potential dementia protection, researchers caution that larger, longer trials are needed to confirm durability and daily-life impact.
