I did some research on gut health stomach bacteria its role in serotonin production and depression and our over all good health and well being. along with keeping our digesting proper and so on. In the end iw as blown away by how importaint good gut health is i had no idea. a healthy gut is as important as a healthy mind and vice versa i think they both need each other to be healthy.
that being said i think a probiotic is good but ask your doc if you want more info.
