Fantastic. Someone else was asking about S.boulardii elsewhere. I shall steer them to your comment. Thanks, Jaime. I'm going to take a look at the Reg'Activ, too. I've had a skin issue on my lower back for years which waxes and wanes. For various reasons I strongly suspect candida. Sinus issues, too, so your comments about Reg'Activ are really interesting to me.
