For one thing, treatment with “probiotics” — friendly microbes consumed not as medicine but as a nutritional supplement — may prove helpful in fighting anxiety and depression. Probiotics reduce anxiety and depressive behavior in mice, and similar effects have been seen in a few human studies. Those studies, though, merely showed lower scores on stress and anxiety questionnaires in healthy people after they took probiotics. It will take tests in actual psychiatric patients to see whether probiotics will really be useful treatments for people with serious mood disorders.
