supplementation.
Prebiotic fiber
Dietary fiber is the edible parts of plants or carbohydrates that are resistant to digestion and absorption in the human small intestine, with complete or partial fermentation in the large intestine. 20 to 30 g a day are recommended by the health authorities, in forms of food but this recommendation remains a hard-to-reach target.
Prebiotics are types of soluble fibers that serve as substrate for targeted beneficial bacteria of our microbiome.
Characterization of the active compounds

Rosiom® is a native chitin-glucan biopolymer from the cell wall of the mycelium of Aspergillus niger. Rosiom® combines in a 3D-structure, the nutritional benefits of β-glucan and chitin prebiotics, to modulate the gut microbiota and the production of postbiotics.
ACTIVE COMPOUNDS
Chitin: 30-60%
Glucan: 40-70%
Formulation
Recommended daily dosage: 4.5 g
15-year research program on Rosiom®

Rosiom® has been approved as Novel Food in Europe and has a self-affirmed GRAS status in the USA.
Rosiom®: targeted prebiotic effect for probiotic benefits
CLINICAL TRIAL 1
POPULATION
15 healthy men & women
Age: 21 ± 1 years old
LENGTH
21-day supplementation
INTAKES
4.5 g /day of Rosiom®
Fiber-controlled diet
Rosiom® modulates selectively the activity and composition of gut microbiota with a specific selection of positive bacteria (Roseburia spp), butyrate- and vaccenic acid-producer.

- Key role in the digestion of complex sugars
- Part of commensal bacteria producing short-chain fatty acids
- Sufficient presence of Roseburia is characteristic of a healthy gut & modification in abundance may affect various metabolic pathways
Rosiom®: postbiotic activity through short- & long-chain fatty acids (SCFA & LCFA)

IMMUNE HEALTH SUPPORT

CARDIOVASCULAR HEALTH
Rosiom® - Immune health support

EX-VIVO STUDY
Ex vivo approach on a human-like model of gut immune system axis: Caco-2 (epithelial cell line) / THP1 (macrophage cell line) co-culture.
Evaluation of the barrier function

The increase in the SCFA production is proven to reinforce epithelial thigh junctions:
Rosiom® improves the physical barrier first-line of immune defense.
Evaluation of the barrier function

The increased release of postbiotics modulates the inflammatory response:
- Pro- and anti-inflammation markers are rebalanced
- The inflammatory sentinel CXCL-10 significantly decreases
Rosiom® reinforces the second and third steps of the innate immune response.
