Key Takeaways
Prebiotic supplements can help keep your fiber routine more consistent when travel disrupts your eating.
Prebiotics feed beneficial microorganisms in your gut and can support digestive health.
Check how much prebiotic fiber you get per serving instead of relying on the front of the package.
Choose the supplement form that's most convenient for your trip.
At home, you probably have a good sense of what you'll eat on a normal day. But travel is different. Your meals often depend on what's nearby, and many of the fiber-rich foods you normally rely on may not be as available.
This can throw your digestion off even when nothing is technically “wrong.” Prebiotics help feed the beneficial bacteria already living in your gut.1 They're naturally found in fiber-rich foods, but a supplement with prebiotics can give you a more consistent source when your meals are less predictable.
Prebiotics for travel are ideal when gut health is already part of your normal routine. A supplement gives you a consistent source of prebiotic fiber even when your meals change from day to day.
Look at the amount per serving: ISAPP consumer guidance suggests aiming for about 3 to 5 grams of prebiotics per day.1
Pay attention to what's actually in it: The product should clearly identify its prebiotic and dose instead of relying on a vague “gut health” claim.
Consider the format: Gummies and individually packed servings are easy to pack without bringing an entire container of powder along for the journey.
If you already take prebiotic fiber every day, keep roughly the same routine on your trip. Pack enough servings for the days you'll be gone and include an extra one or two in case plans change.
Pay attention to your water intake, too. Adequate fluids help fiber move through the digestive system.2 That becomes especially worth remembering on travel days when your usual drinking habits may be off. As for your food choices, remember that a supplement can help provide consistency, but your overall diet remains an important part of maintaining your gut health while traveling. Beans, whole grains, onions, garlic, and other plant foods can provide naturally occurring prebiotics as part of your diet.1
If you prefer a chewable option, AG1 Essentials Gummies provide 5 grams of prebiotic inulin and tapioca fiber per serving, plus 50 vitamins, minerals, and whole-food-sourced ingredients.* Each daily serving comes in its own pack of eight gummies, so there is nothing to mix or measure.
AG1 Next Gen Travel Packs include prebiotics along with probiotics, phytonutrients, vitamins, minerals, and whole-food-sourced ingredients in a convenient individual powder serving.
AG1 Pro is also available in Travel Packs, with prebiotics plus additional ingredients designed to support performance, muscle recovery, and healthy aging.
Keep your daily nutrition easy to pack with AG1 Essentials Gummies or individual AG1 Next Gen or Pro Travel Packs.
If prebiotics are already part of your routine, you can continue taking them on your trip. If you're starting a new prebiotic supplement, try it at home first. Increasing prebiotic doses gradually may help reduce gas or bloating.2
Try to keep some familiar sources of fiber in your meals and drink water regularly. A prebiotic supplement can help give you a consistent amount of prebiotic fiber when your normal eating routine changes.
Yes, especially if you increase your fiber intake quickly. Starting gradually gives your digestive system more time to adjust.2
AG1 Next Gen travel packets contain 2g of fiber as well as pro- and prebiotics (among 75+ ingredients), while AG1 Essentials Gummies contain 5g of fiber and a prebiotic complex—both great options for travel. When deciding on a travel prebiotic, look for a useful amount of prebiotic fiber and choose something easy to fit into your travel routine.
