2FX-Complex® is a bioactive polysaccharide complex designed to work through a unique physical bio-barrier mechanism. It helps reduce unwanted microbial pressure on the gut environment and strenghtens the gut-barrier, supporting the conditions your microbiome depends on.

Instead of adding more bacteria, it works by supporting the environment itself, a fundamentally different approach to daily gut health.

2FX sits at the center of our formula.

Acacia fibre is a highly soluble prebiotic fibre valued for its exceptional digestive tolerance and gradual fermentation. Unlike many other fibres, it is fermented slowly throughout the colon, providing a steady source of nourishment for beneficial gut bacteria while being gentle on the digestive system. Its excellent tolerability and naturally prebiotic properties have made acacia fibre a trusted ingredient in advanced gut health formulations.

Psyllium husk is one of the world's most extensively used soluble fibres, valued for its unique ability to absorb many times its own weight in water. As it forms a soft gel within the digestive tract, it helps support healthy bowel function while contributing to a balanced daily fibre intake. Carefully selected as a cornerstone of the Pyour ecosystem for its gentle yet effective functionality.

Inulin is a plant-based soluble fibre, naturally found in chicory root, that passes through the digestive tract undigested until it reaches the colon. There, it serves as a natural food source for beneficial gut bacteria through gentle fermentation. Thanks to its well-established prebiotic properties, inulin has become one of the most widely used fibres in advanced microbiome-focused nutritional formulations.

Lactobacillus salivarius is naturally present in the human digestive tract and has been widely studied for its ability to thrive within the gut environment. Its natural compatibility with the microbiome has made it a valued strain in advanced probiotic formulations designed to support microbial diversity and a balanced gut ecosystem.

Bifidobacterium bifidum is one of the best-known members of the Bifidobacterium family and has been extensively studied for its natural presence within the human digestive tract. Its long history of use and close association with a healthy gut microbiome have made it a cornerstone of many advanced multi-strain probiotic formulations.

Lactococcus lactis subsp. lactis has been widely studied for its role in fermentation and its compatibility within complex microbial formulations. Its extensive research history and well-established safety profile make it a valuable addition to premium multi-strain microbiome formulations.

Lactobacillus reuteri is naturally present in the human digestive tract and has been extensively studied for its close relationship with the gut microbiome. Its ability to adapt to the intestinal environment and its long history of scientific research have made it a highly regarded ingredient in advanced multi-strain probiotic formulations.

One of the most familiar probiotic strains, Lactobacillus acidophilus has been used in food and nutrition for decades. Its long standing association with fermented products has made it a foundational component in many traditional and modern formulations.

Lactobacillus paracasei is often selected for its compatibility with other bacterial strains. Its steady profile and cooperative behaviour make it a common inclusion in blends designed for consistency and long term use.

First identified in fermented vegetables and plant-based foods, Lactobacillus plantarum is closely linked to fibre-rich dietary contexts. Its adaptability and broad metabolic capabilities have made it a natural fit in modern, plant-forward formulations.

Lactobacillus rhamnosus is widely recognised within probiotic formulations for its ability to withstand challenging conditions during digestion. Because viability matters, this strain is often included in blends where robustness and survival through the digestive process are key considerations.

Bifidobacterium lactis
Known for its robustness and formulation stability.
Amount per serving: 60mg

This strain is commonly selected for its reliability and consistency under a wide range of conditions. Bifidobacterium lactis is valued by formulators for its stability during production and storage, making it well suited for products designed for regular, long-term use.

Bifidobacterium longum is frequently described as a highly adaptable strain, present from early life through adulthood. It is often selected for its ability to coexist with different dietary patterns and changing gut environments. This flexibility has made it a popular component in more comprehensive probiotic blends.

Saccharomyces cerevisiae is a yeast long used in food and nutrition, now also appreciated as a postbiotic ingredient. It contains naturally occurring beta-glucans and other nutritional components. As a non-living ingredient, it fits seamlessly into contemporary formulations that focus on composition, structure and smart ingredient design rather than live cultures alone. 

Methylcobalamin is an active form of Vitamin B12. Vitamin B12 contributes to normal energy metabolism, normal nervous system function and normal psychological function. It also supports red blood cell formation and helps reduce tiredness and fatigue. This form is readily used by the body and is suitable for daily intake.

Biotin contributes to normal macronutrient metabolism and normal energy-yielding metabolism. It also supports the maintenance of normal mucous membranes and normal skin. Biotin plays a role in several metabolic pathways and is commonly included in daily nutrition formulas.

Vitamin B3 in the form of nicotinamide contributes to normal energy metabolism and the maintenance of normal mucous membranes. It also supports normal psychological function and helps reduce tiredness and fatigue. Because nicotinamide does not cause flushing, it is a gentle and stable form suitable for daily use.

Zinc bisglycinate is a well-tolerated and highly bioavailable form of zinc. Zinc contributes to normal immune function and normal macronutrient metabolism. It also plays a role in cell division and the maintenance of normal tissues. The bisglycinate form is commonly chosen for its absorption characteristics and suitability for regular daily intake.

Magnesium bisglycinate is a highly bioavailable and gentle form of magnesium. Magnesium contributes to normal muscle and nerve function and plays a role in energy metabolism. Because it is bound to glycine, this form is generally well tolerated compared to other magnesium sources. Magnesium bisglycinate is commonly used in daily nutrition formulas where absorption and tolerability are key considerations.

L-Glutamine is a naturally occurring amino acid found in the body and in protein-rich foods. It is involved in normal amino acid metabolism and is used by tissues with a high cellular turnover, including the gastrointestinal tract. During periods of increased physical demand, glutamine is actively utilized as part of normal physiological processes. It is considered a conditionally essential amino acid in specific situations.

L-Tryptophan is an essential amino acid that cannot be produced by the body and must be obtained through the diet. It is the natural precursor to 5-hydroxytryptophan (5-HTP), which is subsequently converted into serotonin. Through these natural biochemical pathways, L-Tryptophan plays a fundamental role in normal human physiology and is an important component of balanced nutrition.

Panax ginseng has been valued in traditional herbal practices for thousands of years and is widely recognised for its naturally occurring ginsenosides, the plant's characteristic bioactive compounds. It is best known for its long-standing association with vitality, resilience and overall wellbeing, making it one of the world's most respected botanical ingredients. Carefully standardised, it is selected for its consistent quality and premium botanical profile.

Citric acid is a naturally occurring organic acid found in citrus fruits and widely used in food and nutrition. It plays a central role in basic biochemical processes and is valued for its sour taste and functional properties. In formulations, citric acid is commonly used to enhance flavour and contribute to product stability.
