Which probiotic strain is best for post antibiotic (flagyl-cipro) therapy of sibo. also highly lactose intol. sibo symptoms returned very quickly.

Probiotics: There are several high potency probiotics available, such as klaire complete, and orthobiotic, two of my favorites. A good post antibiotic restorative probiotic should have at least 4 strains of acidophillus and bifido bacteris, and a friendly competitor for candida, like florastor. Ortho biotic has all of those in one supplement. The other thing to look for is billions of cfu (cocloies).
