I'm not sure, all I know is that I put some electrolytes powder in a glass of water, drank half of it, woke up the next morning, wasn't sure what was sitting there, drank it, and all of a sudden, gurgle, giggle, motion, and within a short amount of time, sat on the can, two little turds and I cried and I laughed, then drank another cup of that stuff, then farting in the bathtub like a little boy..and giggling...also, vitamin B-thiamine and vitamin D3, but D in moderation, the body, the system needs all of these for the GI to work properly...good luck to you, best is also hiking a lot, walking, or swimming, get moving..that was my hard part, but it sure seemed to help, and perhaps yoga, not only child's pose, but also like bow or cobra, stretch that tummy both ways...LOL ;o)
