Restore Your Body’s Natural Rhythm® with RestoraLAX®. RestoraLAX® is an osmotic laxative which contains 100% Polyethylene Glycol 3350 (PEG 3350) as the active ingredient. It relieves occasional constipation and irregularity without the side effects of gas, bloating or cramps. RestoraLAX® works by retaining water in the bowel to provide softer stools and increase the frequency of bowel movements. This allows bowel movements to occur more normally so you can get on with your day. To be sure this product is right for you, always read and follow the label. ®Registered trademark used under license. © 2016 Bayer Inc., Mississauga, Ontario L4W 5R6.
