Product Details

Everyday foods fill your stomach – but Gut Fuel turns them into superfoods that nourish your gut bacteria. This microbiome is the foundation of a healthy gut – and a healthy gut = a healthier body. Inside the gut, you’ll feel smoother digestion with greater gut regularity and resilience. In turn, a higher-functioning gut promotes a better metabolism, higher energy, and immune health support that you can feel from the inside out.

  • An excellent source of fiber (6g per serving)
  • Fuels the gut-metabolism connection
  • Low FODMAP, gentle for sensitive guts

Slide 1 of 3

Most fiber powders get goopy and thick rather quickly. Gut Fuel does not...it is very easy to blend & has no taste. It is easy to "disguise" kids & picky adults won't know it's there.

After using Gut Fuel for a month I am very happy to say I feel less bloated and it even helped curve cravings in between meals. I didn’t realize how much better my body could feel with being regular.

My digestive system was already in pretty good shape with no major issues, but Gut Fuel made it even better. Regularity improved, consistency improved and hunger pangs improved.

Pendulum is an awesome company, and their products are amazing, including Gut Fuel

This product makes it easy to address fiber intake and gut health as a supplement. It mixes easily, and does not require much effort to integrate into a habit.

easy to blend fiber

Most fiber powders get goopy and thick rather quickly. Gut Fuel does not...it is very easy to blend & has no taste. It is easy to "disguise" kids & picky adults won't know it's there. I would purchase this product in the pouch and in individual servings for travel.

You’ve got questions. We’ve got answers.

Even with good intentions, most people still fall short of their fiber intake. Gut Fuel can help make up those everyday gaps to supplement a healthy diet. It’s a reliable source of fiber you can count on, even if on your cheat days.  

Gut Fuel is not just fiber. It’s a blend of diverse prebiotics — multiple fibers, resistant starches, and polyphenols — so your microbiome has more nutrients to snack on.

Gut Fuel is compatible with low FODMAP and sensitive stomachs. To help mitigate potential irritation, you can slowly introduce Gut Fuel into your diet and gradually build to daily use if you feel comfortable. 

We can't say for certain how Gut Fuel will impact your gut. Your tolerance for prebiotics is heavily influenced by your current diet, lifestyle, and other health factors. You may initially experience some gas and bloating when starting Gut Fuel, but that’s totally normal. Your body is acclimating to your increased fiber intake – it’s a sign your microbes are eating well.

We recommend one scoop or packet of Gut Fuel every day to regularly support your gut. Consistency is key to continue feeling the effects of a healthier gut. 

Store at room temperature and keep resealable pouches closed.
