Probiotics very effective in reducing symptoms of depression: Study

Probiotics, commonly championed for their digestive benefits, might be a valuable tool in reducing the symptoms of depression and anxiety.

This study, led by Viktoriya L. Nikolova from King’s College London, was published in JAMA Psychiatry.

The research focused on participants whose depressive symptoms remained unmitigated despite antidepressant treatment, a situation referred to as an “incomplete response.”

Results revealed a notable reduction in depressive and anxiety symptoms when probiotics were administered in conjunction with their antidepressants.

The trial consisted of two groups, containing 24 and 25 participants. One group was given probiotic treatment, while the other received a placebo. The allocation was double-blind, ensuring neither researchers nor participants knew who was receiving probiotics and who was given a placebo.

Improvements in symptoms were observed across both the probiotic and placebo groups throughout the study. However, the probiotic group demonstrated more significant strides in symptom reduction.

Recent studies have shown similar results; improving gut health with probiotics has a positive effect on mental health.

What are the best food sources of probiotics?

There are numerous probiotic-rich foods that people can incorporate into their diets to aid better gut health.

“I favor foods that are naturally rich in probiotics, such as yogurt, sauerkraut, miso, tempeh, and kefir. Good sources of prebiotics (high fiber foods that promote the growth of beneficial bacteria) include whole grains, apples, bananas, onions, garlic, asparagus, and artichokes,” Dr. Lerner said.
