I don’t think it matters really which one you use. I don’t feel that the more billion count means its more effective; I take one with 12.5 billion and find it to be just as or more effective than a 50 billion probiotic I took before. If you take the megaflora or HMF neuro that me and Able recommend, this may be the best bang for the buck.
If you eat a ton of corn and starch, the candida with slowly come back…and at that point you could be throwing the supplements away. Your body is at a delicate balance right now and I wish you nothing but good luck.
