From larch to your gut
CFB-03 Microbiome contains arabinogalactan – a natural fiber derived from the North American larch tree. In the large intestine, it acts as a prebiotic: food for your beneficial gut bacteria, especially Bifidobacterium.
In a placebo-controlled study with 199 participants, a 23% reduction in common cold episodes was observed compared to placebo.
