Phybrix® – a pioneering multifunctional ingredient for improved gut health
Phybrix® is a natural, multifunctional, and insoluble fiber derived from upcycled and precision-engineered lignin. It’s a plug-and play ingredient that supports digestive balance, has antioxidant and anti-inflammatory effects as well as pre-biotic-like effects and detoxifying action.
A functional fiber for gut comfort and balance
Phybrix® is not a probiotic because it is not alive and does not contain bacteria. It is not a classic prebiotic because it is only minimally fermented and does not rely on rapid bacterial feeding to work. Instead, Phybrix acts as a functional fiber, supporting gut comfort and balance through mechanical and protective actions rather than bacterial stimulation.


Naturally sourced and derived from upcycled lignin
Phybrix® is derived from upcycled agricultural residues. It’s designed from modified sulfur-free soda lignin originating from hydrolysed fibers of wheat straw and Tripidium Bengalense, a tall, drought-resistant perennial grass belonging to the family Poaceae. Phybrix is a natural, upcycled and gluten-free ingredient.
A plug and play solution
Phybrix® is designed as a plug and play solution for a wide range of gut health products. It’s a unique base to design and formulate your own gut health product brand. Paired with probiotics or other fibers, it gives beneficial bacteria a place to grow and helps them produce vital nutrients that improve digestion and strengthen the immune system

Phybrix® multifunctional effects
Digestive balance
- Phybrix® acts as a dietary fiber because the body cannot digest it. It supports gut health in two main ways.
- Better bowel function: It absorbs water and adds bulk to the stool, helping to keep digestion regular and preventing both constipation and loose stools.
- Protective barrier: Its small particles can bind to toxins and harmful bacteria, preventing them from irritating the gut wall.
Antioxidant and anti-inflammatory
- Phybrix® contains chemical compounds that support gut health in two main ways.
- Reduces stress and inflammation: These compounds act as antioxidants that neutralize harmful molecules, which can help ease gut irritation, bloating, and gas.
- Binds harmful substances: It can trap toxins and bacterial by-products before they cause damage, reducing irritation and keeping the gut lining strong.
Pre-biotic-like and detoxifying action
- Phybrix® helps nourish the gut and remove toxins through three key actions.
- Feeds good gut bacteria: It is slowly broken down by gut bacteria, producing healthy fats that nourish the colon lining, promote good bacteria, and keep bad bacteria in check.
- Blocks harmful bacteria: Its natural properties can disrupt and inhibit dangerous bacteria like E.coli.
