Don't know if they reformulated it...but I think that Chomper used to contain senna or cascara sagrada...or both. I assume Chomper is still part of their program...it's been several years since I used it...if not, Chomper was not a part of the shakes, but an additional cleansing tablet/capsule(?)...just in case they're calling it something different now.
BTW...it is not necessary to get rid of candida prior to a colon cleanse...in fact, a Colon Cleanse can greatly assist in eliminating candida.
