Polyethylene glycol 3350
"I have been taking diabetic medications like Byetta, victoza, bydureon, and trulicity for at least the last 10 years. These medications slow down your digestive process. I have had chronic  constipation since I started them.  PEG is truly a miracle, no joke. I went from having to force myself to go every 3 or 4 days. Which was miserable. To being regular. I take 1 cap full once a day and I go at least once a day without struggle. I will continue this product. Like one person earlier said.  "If you have never experienced this situation, you really have no idea what is is like to go from chronic constipation to being regular again."
