Do you Know of a Good Probiotic (Flora) Formula for Good Colon/Digestion Health etc…?

My Mom wants me to find her a good probiotic (good bacteria) system that will help her w/her colon, digestion etc… I found this system online: http://shop.liveleantoday.com/product/nutrihealth-flora-source-1114.cfm

Do any of you have any experience w/a probiotic formula? What was your experience? Which formula do you recommend?

Thanks!
