Brazilian Study Explores Kefir’s Potential in Combating Alzheimer’s Disease

Scientists in Brazil recently conducted a review to examine the effects of the probiotic kefir on Alzheimer’s disease. As the most common form of dementia, Alzheimer’s currently has no cure, prompting researchers to explore new preventive and therapeutic approaches.

The review included seven studies, one of which involved human participants. Although the study pool was limited, findings suggest that kefir may help improve symptoms. Growing evidence highlights the connection between gut health and brain function, indicating that maintaining a healthy gut microbiome could play a role in preventing and mitigating dementia.

Given kefir’s unique microbial composition and its known benefits for gut health, researchers sought to assess its potential as a supplement for Alzheimer’s patients. Despite the limited number of studies, results were promising, with one human study demonstrating improved cognitive function and memory test performance following kefir supplementation.
