Gut bacteria and fiber supplement for mild memory problems
Part of Mental health clinical trials.
This study tests whether a daily supplement containing special bacteria and fiber from agave (a type of prebiotic) can improve memory and thinking in older adults with mild cognitive impairment. It looks at the connection between the gut and the brain.

This study tests a daily supplement (a probiotic called Lactobacillus acidophilus plus a fiber called inulin) to see if it might help improve memory and thinking in adults with long-term obesity and mild cognitive impairment. If you qualify, you would take the supplement or a placebo for a period of time while the study team monitors your cognitive function.
This study tests whether taking a daily supplement with inulin (a type of fiber) and a probiotic (a helpful bacteria) can improve memory and thinking in older adults with type 2 diabetes. It may also help with blood sugar control.
This study tests whether taking a specific probiotic (a beneficial bacteria) can help improve memory and thinking in people with mild cognitive impairment who show signs of amyloid in the brain. If you qualify, you'll be randomly assigned to receive either the probiotic or a placebo (a dummy pill) to see if it helps.
This study tests whether a probiotic (a supplement with helpful bacteria) can help slow down memory and thinking problems in people with mild cognitive impairment (MCI). It is for adults aged 60–85 who have noticed their memory getting worse over time but can still handle daily activities.
This study looks at how a probiotic supplement affects the gut and thinking in older adults, including those with mild cognitive impairment or Alzheimer's. It may help explain if improving gut health can support brain health.
This study tests whether combining probiotics (good bacteria) with riboflavin (vitamin B2) can help improve thinking and memory in older adults who have mild cognitive issues. If it works, it could offer a simple way to support brain health.
