Inulin: The Gut-Brain Boost You Know About

A landmark UK study just revealed something big: Inulin could help boost brain power in older adults.

In a first-of-its-kind twin trial, researchers gave people over 60 a simple blend of protein + prebiotics — either inulin or FOS (fructooligosaccharides).

After just 12 weeks, those taking the prebiotics scored higher on memory and learning tests — tests that are also used to spot early Alzheimer’s.

Even better? 

Their gut microbiomes improved too, especially levels of Bifidobacterium, a good gut bug linked to better cognitive function.

Most of the participants were healthy, aging adults — but even without obvious signs of decline, their brains responded positively to a gut-focused supplement.

Take Home Message:

• Gut health is brain health. This study adds weight to the “gut-brain axis” theory: the idea that feeding your gut can directly benefit your mood, memory, and mental clarity.

• Inulin affordable and widely available. Found in foods like the Jewish artichoke or in pure powdered form (like Wonder Foods' Organic Inulin).

• Effects were seen in just 12 weeks. No drugs, no side effects, just smarter nutrition.
