Okay ! Threelac is a blend of three lactic bacteria= it IS a probiotic. A very expensive one if you want my opinion so dont waste your money there since you already have bought some probiotics.
If you do not have leaky gut (look here for symptoms://www.curezone.org/forums/fm.asp?i=1026759#i )
Then - once you are comfortable with the diet - your next step will be a
Bowel Cleanse to help all the toxins (which feed candida) and the candida threads out.
For now, stick to the diet and in a few weeks start the bowel cleanse.
I would recommend the P & B shake for bowel cleanse:
