Cheap Daily Supplement Appears to Boost Brain Functions in Older People

A randomized double-blind twin trial at King’s College London tested daily inulin or FOS mixed into protein powder in adults aged 60+.

After 12 weeks, participants taking inulin or FOS generally scored higher on a visual memory and learning test and showed increases in Bifidobacterium levels.

The study found no significant improvement in muscle loss and noted the trial cohort was mostly female; results were published in Nature Communications.
