Synbiotic for cognitive function in adults with obesity
Official title: Effect of Lactobacillus Acidophilus Combined With Inulin on Cognitive Impairment in Patients With Obesity
Run by Anahuac University · NCT07810517 · Data updated 2026-11-12
A synbiotic containing Lactobacillus acidophilus and inulin is being tested to see if it improves cognitive function in adults with obesity and mild cognitive impairment.

Is this trial a fit for you?
✓Likely a good fit
Adults aged 30–40 with obesity for at least 10 years and mild cognitive impairment.
✕Probably not a fit
Individuals without the synbiotic response or with contraindications may see no cognitive benefit.

What this trial studies
This randomized crossover study enrolls adults aged 30–40 with obesity and mild cognitive impairment to receive a synbiotic (L. acidophilus LA-5 plus inulin) and a control treatment in alternating periods. Cognitive function will be measured with MoCA, MMSE, and M@T, while gut- and brain-related biomarkers such as fecal butyrate, Lactobacillus acidophilus, serum inflammatory cytokines, and BDNF are also explored. The crossover design allows each participant to serve as their own control, helping to compare effects between interventions. The trial aims to clarify whether the synbiotic can favorably influence cognitive measures and related biomarkers in this population.
Why it matters
Potential benefit: If successful, participants could experience improvements in cognitive function and related biomarkers, potentially offering a non-drug strategy for cognitive health in obesity.
How similar studies have gone: Similar synbiotic approaches have shown signals of gut-brain effects in some populations, but this exact combination in obesity-related cognitive impairment is relatively novel and exploratory.
