Jay,
My naturopath gave me S. boulardii when I was taking a lot of antibiotics and was worried about yeast. She thought it would be better able to fight off yeast.
About the lactobacillus, I've wondered for awhile if can get past your stomach acid if you just eat it in yogurt versus the enteric coated capsules. My daughter has IBS and ate lots of yogurt but it wasn't until she started eating probiotics that she noticed it helping her. She also thinks she might be sensitive to dairy too so that might be a factor. She hasn't quite figured it out.
There is so much conflicting info. Who knows sometimes?
Annette
