C.P.
My son and I both take Primadophilus original that we get from the health food store. His is children's chewable and I give it to him every morning. He does not get sick in the winters anymore. I had a yeast infection that was really bad and nothing seemed to get rid of it for very long until I started taking Candex and probiotics. Both are from the health food store. I have not noticed any side effects.
