FS-3B is revolutionising microbiome health.
Fibres and fermentable compounds that feed probiotics and stimulate their growth.
Role: They promote a diverse and resilient microbiome, as well as healthy bowel transit.

Live micro-organisms that enrich our gut microbiome.
Role: They colonise the intestinal lining, creating a protective physical barrier, interact with the immune system and contribute to the digestion of certain molecules.

Bioactive substances produced by live probiotics or after they die: vitamins, peptides, enzymes, organic acids, amino acids.
Role: These molecules are involved in many mechanisms in the gut and throughout the body.
