Fibersentials is AB INTRA’s fiber-focused line, crafted to close the modern fiber gap while supporting microbial diversity, metabolic health, and daily digestion.
Formulated with gentle, fermentable fibers and backed by science, Fibersentials is about more than regularity, it’s about feeding your inner foundation.
While fiber may seem basic, its impact is anything but. Fermentable fibers nourish beneficial gut microbes, promote short-chain fatty acid production, and help regulate appetite, blood sugar, and bowel function. Our formulas work in harmony with your microbiome—not against it.
Gentle prebiotic fibers like GOS and Fibersol® feed your gut microbiota, promoting balance and diversity.
Glucomannan and resistant starch support fullness, healthy weight, and blood sugar regulation.
Designed to work with your body’s natural rhythms—Fibersentials supports regularity without discomfort.

An advanced fiber supplement combining glucomannan, Fibersol®, and GOS to support weight loss, promote satiety, and nourish your gut microbiota.
Fiber may seem simple, but it’s one of the most overlooked tools for gut and metabolic health. Yet most people today fall far short. While our ancestors consumed over 100 grams of fiber a day, modern diets average just 15–21 grams, leaving a gap that affects digestion, immunity, and metabolic resilience.
Fibersentials is made to close that gap—gently and effectively. Our formulas work in harmony with your microbiome, helping you restore balance from within.
Our formulas are only as extraordinary as the ingredients within them. Each one is selected for its proven benefits and ability to work in harmony, creating powerful solutions that support your well-being from within.
A gel-forming fiber rich in arabinoxylans. It retains water throughout the colon, softening stool and supporting regularity, while helping deliver nutrients further into the gut.
This prebiotic fiber fuels beneficial bacteria like Lactobacilli and Bifidobacteria, promoting better digestion, a stronger immune system, and a happier gut.
A highly viscous soluble fiber from konjac root. It absorbs water in the stomach to form a gel-like mass, promoting fullness, slowing gastric emptying, and helping reduce energy intake when used as part of a balanced diet.
A resistant starch that ferments slowly, supplying a sustained prebiotic boost. About half is metabolized by gut bacteria, producing SCFAs that nourish the microbiome, while the other half adds gentle bulk for digestive comfort.
Fiber is the foundation of a diverse microbiome. By feeding beneficial microbes, Fibersentials supports balance, resilience, and the production of essential metabolites like SCFAs.
Psyllium husk and Fibersol® are a great combination—effective yet gentle. Love the clean formula!*

Because most diets fall short on fiber. Fibersentials provides a simple, effective way to bridge the gap, feeding beneficial microbes and supporting the production of short-chain fatty acids (SCFAs) that benefit digestion, immunity, and overall health.
Fibersentials is a gut health supplement formulated with a smart blend of fast- and slow-fermenting fibers, providing complete digestive and microbiome support. Unlike many fiber products, it contains no additives, no sweeteners, flavors, colors, or fillers. Because even small additives may disturb microbial balance.
Our formulation is guided by the way microbes naturally behave. When multiple fibers are present, bacteria often follow a “hierarchical preference,” using some fibers first while delaying others. This staggered fermentation allows activity to continue deeper into the colon, supporting more sustained microbial metabolism and the production of beneficial short-chain fatty acids (SCFAs).
Fibersentials was formulated with gentle fibers to minimize bloating or discomfort. If you’re new to fiber supplementation, start with a smaller amount and gradually increase as your gut adapts. For practical tips on how to acclimatize, see the guidance on the product pages for Fibersentials FLOW and Fibersentials SHAPE.
While Fibersentials is generally well-tolerated, if you have specific medical conditions (like IBS, IBD, or other digestive disorders), it’s best to consult with your healthcare provider before introducing new supplements.
No supplement can fully replace a diverse diet rich in plant foods. Fibersentials is designed to complement your diet, helping you reach recommended daily intakes and feed the microbes that thrive on these fibers.
Yes, our gut health supplements are made to complement one another and are even more effective when taken together. Each formula is a building block in your routine, designed to work synergistically for optimal results.
