Fructo-oligosaccharides (FOS) are a type of soluble fiber present in various vegetables such as chicory and onions. This natural compound can only be partially digested by humans, leaving undigested portions as food for "friendly" bacteria, Bifidobacteria and Lactobacilli species. This prebiotic effect means that as beneficial bacteria multiply, harmful bacteria and yeasts are controlled, so fewer toxins are produced. This leads to better bowel tone, more regular bowel movements and a reduction in digestive 'discomfort'. Format: 500 gr
