Partial Hydrolysed Guar Gum relieved symptoms in constipation-predominant and diarrhoea forms of IBS and improved the quality of life. Moreover, Partial Hydrolysed Guar Gum appears to exert prebiotic properties, by increasing the concentration of intestinal short-chain fatty acids, Lactobacilli and Bifidobacteria. Partial Hydrolysed Guar Gum may also lower the level of Firmicutes bacteria and increase Bacteroidetes to promote weight loss.
