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.

I have had problems for years, ever since I was a little girl. I talked to my doctor about what I could do on a regular basis. I don't have problems since taking clearLax. Another member of my family has now started taking clearLax, and it has helped him.

Makes Stools Soft

My husband is on a lot of prescription medications for heart disease which make him irregular & constipated. Member's Mark Soft Lax is a generic for Miralax & husband puts a Tsp in coffee each morning which causes his stools to be soft & bowel movements regular. It comes in a powered form, had no taste, no side effects, it doesn't cause cramping or diarrhea, it only softens the stool & helps you to go daily! Good price, lasts a long time!

Good product

Works well. Tasteless and no gritty texture. Very gentle so no rushing to find a restroom. I even use it in my cats wet food per my vets recommendation. 1/8 tsp for 2 days keeps my geriatric cats going if they are constipated. It dissolves quickly in liquid . As good as the name brand product but far less costly. A friend confided she always has problems when on vacation, traveling or when routine changes. I gave her a bottle to try. She swears by it and won’t leave home without it.

Best powder Laxative for the money

I have to take this everyday due to the medicine I am taking. I used to have a RX for it before it was available over the counter. I am very glad I do not have to go to the drug store all the time for this product. For the money this works just like the expense Miralax. I know as I have been having to use this for over 10 years. So glad I am able to get this product through Sam's Club.

Great buy, great price

Great Buy, for a great price. I actually use this mostly for my kitty cat. She has trouble, so this helps her out a lot. She weighs about 7 pounds and I give her 1/8 teaspoon every day in her wet food. Also, the prices in the stores are too high. So I am very happy with this purchase.

Works Well

Recommended by my doctor for constipation. I like Members Mark ClearLAX's quality, value, and ease of use. It's very effective, works well, and has a reasonable price point. The product does not have a bad taste or a negative effect on the stomach. I continue to use this product and would recommend its use.

Smooth Move

When you get old, your innards don't work like they used to. This product helps and hasn't caused bloating or other unpleasant side effects for me.
