What is the best probiotic when treating for giardia?

[Nair Bare]

Two new kittens came here with a repeat of Giardia. Would like to add a good probiotic to their treatment plan. Would appreciate some brand names and reasons you suggest it, thank you greatly!

We have seen the med used frequently for treating it is called metronidazole (Flagyl). It can be quite stubborn and we some have had to treat twice. Keeping surfaces clean using disinfectants and keeping the litter box tidy helps to not reinfect. When finished treating it is best to get a new litter box. Has your vet suggested any med yet?
