Bacillus coagulans is a bacteria typically found in the soil and like other bacillus can form spores. It has many application in industry. For example, it was first identified at a canned evaporated milk facility in Iowa (1). It is now used in different probiotics but there are different strains of Bacillus coagulans that research on its benefits is difficult to establish. It comes from the genus of bacillus and the phylum of Firmicutes.

Bacillus coagulans is considered safe(2,3), and often used for veterinary purposes, especially as a probiotic. Several preliminary studies have reported on its possible health benefits for improving the vaginal flora, improving abdominal pain and bloating in irritable bowel syndrome patients and treating as well as preventing recurrence of clostridium difficile associated diarrhea (3-6).
