Bifidobacteria represent one of the major genera in the healthy intestinal tract of humans. As one of the earliest colonizers of the early gut microbiota, bifidobacteria play critical roles in the metabolism of dietary components, otherwise indigestible in the upper parts of the intestine, and in the maturation of the immune system. Bifidobacteria are known to interact with human immune cells and to modulate specific pathways, involving innate and adaptive immune processes. Substantial evidence supports that bifidobacteria confer positive health benefits to their host via their metabolic activities. Bifido SAP can help support gastrointestinal health and promote a favorable gut flora.
