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.
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.
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.
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 human milk oligosaccharide that feeds beneficial bacteria, particularly Bifidobacteria, helping your gut microbiome thrive and stay balanced
This prebiotic fiber fuels beneficial bacteria like Lactobacilli and Bifidobacteria, promoting better digestion, a stronger immune system, and a happier gut.
A clinically-proven probiotic strain that strengthens your gut barrier, supports immunity, and helps reduce inflammation for a healthier microbiome.
A highly bioavailable form of collagen that supports skin elasticity, hydration, and joint health, working hand-in-hand with gut health for whole-body benefits.
Fiber is crucial for nurturing the gut microbiome, yet modern diets often fall short in fiber. Our Fibersentials range combines scientifically chosen fibers to close the fiber gap, ensuring your gut gets the fuel it needs to thrive.

It goes far beyond collagen alone. COLLAGEN+ is a complete formula that supports your skin from within, layer by layer. It targets the dermis with clinically studied collagen tripeptides, the epidermis with Ceramosides™ phytoceramides, and the gut–skin axis with prebiotics and probiotics. Science-backed and nutrient-rich, it’s made to support skin firmness, hydration, and visible renewal.
It’s never too early—or too late—to support your skin from within. Collagen production naturally starts to decline around age 25, dropping by about 1–1.5% per year. By your 40s, the effects of this decline can become more visible, especially if your skin has been exposed to sun/UV radiation, smoking, alcohol, pollution, stress, poor sleep or imbalance in the gut.
That’s why we recommend starting a consistent regimen in your late 20s to mid-30s, as a proactive investment in your skin’s long-term health. But even if you’re past that point, COLLAGEN+ still supports visible improvement in hydration, elasticity, and barrier strength.
Some customers also reach for COLLAGEN+ seasonally, like in winter, when colder, drier air challenges skin resilience.
Absolutely. COLLAGEN+ pairs especially well with Gutbiotica PRIME or CORE for a complete gut–skin synergy.

Skin renewal isn’t instant. The keratinocyte cell cycle, from the birth of a skin cell to its shedding, takes 40–56 days, and slows with age. That’s why we recommend giving it at least 2–3 full cycles (around 3 months) to experience meaningful changes. You’ll find a 3-month supply under our Bundle & Save.
