Your gut does more than digest your meals. It shapes energy, mood, immunity, skin, metabolism, and the way you feel in your body each day. Yet modern lives aren’t always kind to this inner ecosystem. Stress, age, diet, and environmental shifts can disturb microbial balance and strain the gut barrier.
This is where thoughtful supplementation steps in.
AB INTRA™ creates gut health supplements that blend scientific integrity with nature’s quiet wisdom. Each formula supports the body’s core—your gut, so you can feel more balanced, energised, and resilient.
This guide walks you through the AB INTRA™ range and helps you choose the product that fits your goals.
Understanding Gut Health: A Quick Primer
A balanced gut rests on three pillars:
- A diverse microbiome: a thriving forest of beneficial bacteria
- A strong gut barrier: the physical lining that protects, absorbs, and communicates with your immune system
- Smooth digestion and nutrient flow: so the body receives what it needs, without discomfort
AB INTRA™ formulates supplements that support each of these pillars with targeted ingredients. Below, you’ll find a clear breakdown of every product, who it’s for, and how they differ.
These formulas act as your daily base for microbial balance, gut-lining resilience, and overall vitality.
How Gutbiotica works:
- Targeted nourishment: premium prebiotics including GOS and 2’-FL feed diverse Bifidobacteria and help drive short-chain fatty acid (SCFA) production across the colon.
- Gut-native probiotics: clinically studied, human-residential Bifidobacterium strains selected for stability, crosstalk, and long-term support of a balanced microbiome.
- Strengthen the core: complementary actives, e.g. MGCPQQ® and L-glutamine, work alongside the prebiotics and probiotic to support gut function at a cellular level.
Complete microbiome, gut lining, and digestive support
CORE is formulated as an everyday companion for gut balance. It combines a prebiotic blend + probiotics + L-glutamine for a streamlined, triple-action foundation.
Key benefits
- Supports microbiome balance and daily digestive comfort
- Nurtures gut-lining integrity
- Helps reduce digestive discomfort
Key features
- Galactooligosaccharides and 2’-FL
- These complementary oligosaccharides, though both bifidogenic, stimulate different Bifidobacterium species [1] and support short-chain fatty acid (SCFA) production in both the proximal and distal colon [1–3].
- 5 billion CFU of gut-native BB536
- A human-native Bifidobacterium longum strain that is clinically proven to support digestive health [4, 5], balance the microbiome [6], and contributes to immune function [7].
- L-Glutamine for resilience
- 5 g of L-Glutamine supports tight junction proteins [8] and rapid tissue repair [9], helping maintain a strong, healthy barrier.
Who it’s for
- Anyone looking to strengthen their gut foundation
- Individuals experiencing bloating, irregularity, or sensitivity
- Those beginning their gut health journey
How it differs
CORE is your daily multi for the gut. If you’re unsure where to begin, start here.
Strong health starts at the core. Give your gut what it needs every day.
€ 59,95 incl. VAT
Advanced daily gut health supplement: prebiotics GOS and 2′-FL, Bifidobacterium longum BB536, and L-Glutamine for gut microbiome balance.
Next-generation gut support for healthy ageing
Bifidobacteria dominate early life, but their abundance naturally declines with age [10, 11].
PRIME is formulated to support this shift with Triple Bifidus strains, 2′-FL (a next-generation prebiotic), and MGCPQQ® for cellular energy.
Key benefits
- Supports microbial resilience during ageing
- Enhances energy production and cellular vitality
- Promotes digestive comfort
Key features
- Triple Bifidus Complex: A synergistic mix of B. longum BB536, B. breve M-16V, and B. infantis M-63, inspired by early-life metabolic diversity. Together, they enhance microbial cross-talk and promote cross-feeding of beneficial metabolites with other species, strengthening adaptability and long-term gut ecosystem resilience across changing conditions [12, 13, 14].
- 2′-FL (Human Milk Oligosaccharide): 3,000 mg of 2’-fucosyllactose selectively nourishes Bifidobacterium species due to their unique glycoside hydrolase and transferase enzymes that metabolize 2’-FL [15, 16].
- MGCPQQ®, a nutrient with antioxidant potential and the only PQQ approved as a novel food ingredient in the EU.
Who it’s for
- Adults 45+ supporting long-term microbial resilience
- Individuals seeking energy and cellular support
- Younger adults with disrupted microbiome balance (from poor diet, chronic stress, or alcohol)
- Anyone with gut sensitivity needing deeper support
- Those wanting an age-aligned, advanced formula
How it differs
PRIME goes further than CORE for ageing and specialized needs. Choose it if healthy ageing and energy metabolism are priorities.
Pairs well with
- Gutbiotica L-Glutamine for gut-lining support
- Skinbiotica COLLAGEN+ if skin vitality is also a concern. A perfect bundle for this: Ultimate Glow
- Fibersentials FLOW or SHAPE to help meet daily fibre needs
It’s something you nourish.
€ 119,95 incl. VAT
A next‐generation gut support designed for healthy ageing, formulated with 2’-FL, Triple Bifidus, and MGCPQQ®.
Targeted support for gut lining strength and recovery
A pharmaceutical-grade amino acid known for purity and bioavailability, offering clean, single-ingredient L-glutamine to complement microbiome support.

- Offers flexible dosing for individualized supplementation.
Who it’s for
- Individuals with gut lining sensitivity
- Active individuals needing recovery support
- Anyone wanting a simple, pure gut lining supplement
How it differs
This is targeted support, not a full microbiome formula. It pairs beautifully with CORE or PRIME or COLLAGEN+.
Because resilience begins with a gut that can repair itself
€ 24,95 incl. VAT
A high-purity L-glutamine supplement, supporting gut barrier integrity, immune health, and personalized dosing for tailored gut support.
Fibersentials is built to help you reach meaningful daily fiber intake—your microbes’ essential fuel, and something most modern diets lack. Nature never delivers fiber in isolation, so we follow the same logic with thoughtful blends made from often-missing fibers that work together.
These targeted blends support digestion, satiety, metabolic balance, and microbial nourishment.
Daily fiber for digestion, regularity, and gut harmony
FLOW is crafted to keep things moving smoothly with psyllium husk, Fibersol®, and FOS.
Key benefits
- Bridges your fiber gap with fast- and slow-fermenting fibers [19, 20]
- Supports regularity by promoting regular bowel movements [21]*
- Nourishes beneficial gut bacteria throughout the entire gut
*) Health claims pending approval by the European Commission

Fibersentials SHAPE
Advanced fiber support for weight goals and satiety
SHAPE combines glucomannan, Fibersol®, and GOS to support fullness, metabolic balance, and microbial nutrition. Weight efforts often fixate on calories while overlooking fiber. Yet fiber shapes appetite, digestive regulation, and the health of your gut. Dieting tends to reduce fiber further as food intake drops. SHAPE helps bridge that gap with targeted, convenient support.
Key benefits
- Helps reduce appetite and support weight management[22][23]**
- Promotes satiety between meals[23]**
- Nourishes beneficial bacteria during weight loss diet by combining fast- and slow-fermented fiber [20], [24]
- Supports cholesterol balance [25]***
**) The beneficial effect is obtained with 3 g of glucomannan daily, in three doses of 1 g each, taken with 1–2 glasses of water before meals.
***) The beneficial effect is obtained with a daily intake of 4 g of glucomannan.
Who it’s for
- Individuals focused on weight loss or appetite control
- Those who feel hungry between meals
- Perfect for pairing with CORE or PRIME
How it differs
SHAPE is formulated for satiety and metabolic balance. Unlike standalone glucomannan supplements, SHAPE blends glucomannan with GOS and Fibersol® to nourish the microbiome while supporting appetite and weight control.
A daily ally for fullness, metabolic balance, and microbial support.
