May be worth a try, but I recently went to a new infectious disease doctor for the PPTU problem. She told me to take this stuff, Metagenics UltraClear with PH (medical food) that will change your whole gut/colon envirnment. It cleans you out, detoxifies your colon, kidney, liver. You start slowly and gradually build up to 6-8 scoops per day. She claimed she had blasto as well, tried everything, finally this stuff cleared it up! Amazing huh? Wonder if it could be that simple, but it literally cured her.
Since I have bad candida now, I'm just doing a little bit since it's got some Sugar content, but I think it's a great product and definately worth a try for you. She also gave me some immune support supplements, and Zinc.
