A small clinical trial reports that taking a daily probiotic may modestly improve depression and anxiety symptoms in older adults when used alongside standard antidepressant treatment. The study focuses on seniors who already receive antidepressants; participants are assigned to take either the probiotic or a placebo while continuing their usual medication. According to reporting based on the trial, the group receiving the probiotic shows slightly greater improvement in measures of depression and anxiety than the placebo group. The results are published in the Journal of the American Geriatrics Society.
Both outlets describe the work as early evidence supporting a potential “gut-brain” connection, suggesting that dietary supplements could someday play a supportive role in mental health care for older people. The available information emphasizes that the findings come from a small study, and it does not provide enough detail to establish long-term benefits or determine which specific probiotic strain(s) or dose are most effective. Further research is implied to confirm the effect and assess safety and clinical usefulness across broader populations.
