Psyllium versus Guar Gum: Facts and Comparisons

Psyllium and guar gum are two forms of soluble fiber that are available as commercial preparations, but they have somewhat different properties. While both forms of fiber are helpful in the management of hyperlipidemia, psyllium appears to be more suitable in the management of motility disorders, such as constipation and irritable bowel syndrome. Psyllium (as in Konsyl) offers a higher concentration of fiber per serving, in addition to fewer calories and lower sodium and carbohydrate content. These properties are significant in the management of coexisting hypertension and diabetes. Fewer gastrointestinal side effects seem to be encountered with psyllium. On the other hand, guar gum (as in Benefiber) may have better utility as a thickener, particularlyin the food and textile industry.
