How prebiotic fiber works

Fiber you can’t digest. Your gut bacteria can.

of short-chain FOS in every scoop of Fiber Boost5 g

In the tub

FOSSENCE P95 short-chain FOS, plus a little silicon dioxide so it scoops cleanly. Two ingredients.

In your colon

Microbes in the colon break down complex carbohydrates our bodies can’t digest on their own.

In the research

Healthy adults took 2.5 to 10 g of short-chain FOS a day, and their Bifidobacteria rose.

You are home to trillions of bacteria.

They live in your digestive tract, and fiber you can’t digest is part of what they live on. Our guides explain it in plain words, with every source linked.

Gut health supplements

Gut health supplements with the label, and the research, in plain view.

GoBiotix makes gut health supplements for everyday routines. Most people start with Prebiotic Fiber Boost: an unflavored powder with 5 g of soluble prebiotic fiber in every scoop, from FOSSENCE P95 short-chain fructooligosaccharides (FOS). It has two ingredients, 0 g of sugar on the label, and stirs into coffee, water or a smoothie.

Prebiotic fiber is fiber your body can’t digest but the bacteria in your colon can ferment. In a 2006 study in healthy adults, 2.5 to 10 g of short-chain FOS a day increased Bifidobacteria. Every product page lists the full label, how to take it and the studies we cite.

Not sure where to start? Read the guides or compare every product. Supplements are not a substitute for a varied diet, and it is worth asking your doctor before adding one to a medication routine.

In their words, and on camera.

I put this in my coffee every morning and it dissolves easily. I did figure out that it didn’t dissolve as easily if I added creamer first, so now I add creamer after.

I keep these Fiber Boost sticks in my bag because they’re just easy. Rip one open, pour it into my drink, done. No taste, no weird texture.

It dissolves completely in both hot and cold drinks and has no flavor whatsoever.
