Evidence Summary

Glucomannan (KGM) has demonstrated clinically meaningful improvements in functional constipation, including bowel movement frequency, stool consistency, and quality of life scores, alongside favorable shifts in gut microbiota composition in a double-blind RCT in athletes (PMID: 41117955). A single 3 g dose of a chromium-enriched glucomannan-fructooligosaccharide complex significantly reduced postprandial insulin response and improved satiety markers compared to dextrose alone in healthy adults (PMID: 40490608). When combined with other fibers (inulin, psyllium), glucomannan supplementation over 180 days was associated with significant reductions in body weight and composition in individuals with obesity carrying specific genetic polymorphisms (PMID: 38398881).
