Pre – and probiotics could help with depression

Probiotics, taken either alone or in combination with prebiotics, could contribute to the alleviation of depression. This shows a systematic Review of seven studies. An effect in anxiety disorders could not be determined clearly, as scientists in the journal "BMJ Nutrition Prevention & Health" reports.

Between 2003 and 2019, the researchers found seven studies that had investigated the Use of pre – and probiotics in adults with depression and anxiety disorders. Therein, a total of twelve strains of probiotic bacteria were used, but mainly Lactobacillus acidophilus, Lactobacillus casei and Bifidobacterium bifidium.

Although the studies in their implementation differed significantly from each other, all came to the conclusion that probiotics were used alone or in combination with prebiotics, with a measurable decrease in depression is associated. The results were of the twelve different probiotics eleven potentially useful. The effect on anxiety disorders, however, remained unclear.

Further studies are necessary

Since all of the studies considered to be of relatively short duration and only a few participants had been subject to, are not clear conclusions not yet possible. The researchers consider it useful to further studies on pre – and probiotic therapy of depression perform. People with depression and anxiety disorders often have other disorders, such as impaired insulin production, and irritable bowel syndrome. The researchers therefore underline that pre – and probiotics could act in two ways: they could have a direct impact on Depression or indirectly through the relief of an additional disease.

Foods and supplements that contain beneficial bacteria, which can colonize the gut are known as probiotics. Prebiotics are to thrive, however, substances by the bacteria better.
