The daily supplement “very promising” for an aging population that can improve brain function in people over 60 years of age in just 12 weeks

Taking a daily fiber supplement can improve brain function in people over 60 in just 12 weeks, according to a study.

The pills may improve performance on memory tests associated with early signs of Alzheimer’s disease, according to researchers at King’s College London.

Dr. Mary Ni Lochlainn said she is “excited to see these changes in just 12 weeks,” adding, “This shows great promise for improving brain health and memory in our aging population.”

“Unlocking the secrets of the gut-brain axis could offer new approaches to living healthier, longer.”

The study, published in Nature Communications, tested two plant fiber supplements (inulin and FOS) that help healthy bacteria grow in the gut. The pills were given to half of 36 pairs of twins, and the others were given a placebo.

Those who took the pills performed better on a Paired Associates learning test, an early marker of Alzheimer’s, and on tests of reaction time and processing speed.

Professor Claire Steves said the pills, which are cheap and available without a prescription, “could benefit a wide group of people in these tight money times.”
