FOS – Fructo-oligosaccharides 60 capsules (500mg/capsule)


The use of Fructo-oligosaccharides known as FOS, as a prebiotic, has shown positive effects on beneficial bacteria. FOS are non-caloric and atypical sugars unmetabolized by the human body, yet fermentable by the colonic microbiota, delivering favorable impacts on mineral and trace element absorption. Enhanced mineral absorption2, particularly calcium, magnesium, and iron, subsequent to FOS intake. Postmenopausal women experienced heightened absorption of minerals and trace elements. Apart from mineral absorption, FOS has also shown positive effects on carbohydrate and lipid metabolism, hormone balance, and nitrogen homeostasis. The prebiotic showcases the potential applications in reducing the risk of various diseases7, including constipation, infectious diarrhoea, cancer, osteoporosis, atherosclerotic cardiovascular disease, obesity, and non-insulin dependent diabetes3. FOS’s positive impact1 on beneficial bacteria like Lactobacillus and Bifidobacterium5, resulting in a reduction in potentially harmful bacteria4, alongside butyrate-producing6 microbes such as Faecalibacterium, Ruminococcus, and Oscillospira, showcase the potential of FOS in promoting the growth of beneficial gut bacteria and enhancing bacterial diversity, conferring valuable advantages to the host’s overall health.
