The Two-Week Challenge: Easiest Way to Avoid Occasional Constipation

Do you ever feel sluggish and weighed down by your digestive system? Do you ever worry about when the ‘last time’ was? Are you looking for a way to become more regular or relieve occasional constipation?

If so, the Metamucil Two-Week Challenge is for you!

After just two weeks of daily use the gentle psyllium husk fiber in Metamucil will trap and remove the waste that is weighing you down*, leaving you feeling lighter and more energetic**.

How can Metamucil do this?

Metamucil contains plant-based psyllium husk, which is an excellent way to increase your daily fiber intake. Once ingested, Metamucil forms a thick gel that moves through your digestive system, trapping the waste that weighs you down and removing it in your stool. The gelled nature of the psyllium fiber bulks and softens stool, which helps relieve occasional constipation* as it exits the body.

Why two weeks?

As with any dietary change, your body needs time to adjust. While you may notice the positive effects of Metamucil immediately, it can take up to two weeks to get the full regularity benefits.

Tips for the Metamucil Two-Week Challenge:

  • You can pick the Metamucil fiber supplement that looks best to you to complete the challenge. Metamucil comes in three different forms – powders, capsules, and fiber thins.

  • If you choose powdered Metamucil, you can mix with juice or water, but make sure that they are cold. You can also check out this page for additional great-tasting smoothie recipes!

  • You may experience gas or bloating as your body adjusts to the Metamucil. This is normal and should go away within a few days of starting as your body gets used to the increase of fiber.
