DM, did you read the post on probiotics? The three choices are MegaFlora and Innate, which are basically the same thing, and HMF Neuro Probiotics by Genestra – 2 capsules a day. This one doesn’t contain DDS-1, but it does contain other benefits. Raster swears by this one as being a benefit to his treatment along with others containing DDS-1. It certainly won’t hurt to do one round of this probiotic, plus you’ll receive strains that aren’t in the other two which will be an additional benefit.
