I've eaten a lot of sauerkraut (raw, store-bought) but it didn't seem to do anything.
For the moment, I'm only using Saccharomyces Boulardii.
I had bought a bottle of it before learning about EM, I had began using it for like 3 days before I began using EM alone.
The first few days, I took 20 billions units a day, now I'm down to 10 billions. I should be able to last about 3 weeks with it.
From what I understand, this is about the time at which it begins to act according to testimonials on the page of the product Florastor. The probiotic seems particularly interesting in its capacity to increase enzymes production in the intestines. The yeast is said to be eliminated after 6 days of non-use.
