Product details

Get Your Digestive System Moving

Use a namebrand spout in the ClearLAX neck.

Same as namebrand except for the special spout, but that is easily fixed. Pry the spout from an empty namebrand container. Open the new container of ClearLAX by cutting an "X" in the safety seal. Stuff the 4 flaps of the seal into the neck of the ClearLAX bottle. (This creates friction to retain the namebrand spout.) Finally, push the namebrand spout into the neck of the ClearLAX bottle.

Terrific Sam's Club Deal

Sam's Club Clear Lax 3 pack is a terrific deal that really works well and saves you money. This product works as good as the "name brand" but for so much less. At Sam's, we save money too by buying a convenient three pack.

Every Body Poops

I started taking ClearLax every morning many years ago at the suggestion of my GI doctor. It is tasteless and goes down easily. Works like a charm.
