Probiotics may be useful for treating SIBO, but it’s not clear which strains (or combinations of strains) are optimal.[1][2] Some research has also shown good results from probiotics used alongside during or immediately after antibiotic treatment.[3][1]
Other treatments, such as prebiotics, curcumin, ursodeoxycholic acid, daikenchuto (a traditional Japanese herbal preparation), Serum-derived bovine immunoglobulin/protein isolate, and some antimicrobial herbs have also been studied, but there isn’t enough evidence to recommend their use.
