I do not have any problems with Benefiber because I have no 
alergies and no gluten intolerances.

      Benefiber Change

  As of July 2006, Benefiber has announced that all of their products will no 
longer contain partially hydrolized guar gum. Benefiber will now be made from 
wheat dextrin. According to a phone representative at Novartis, the makers of 
Benefiber, this decision was made to allow for smaller dosages and for a higher 
profit margin. Benefiber guar gum provided 3 grams of soluble fiber per 
tablespoon, whereas Benefiber wheat dextrin provides 1.5 grams of soluble fiber 
per teaspoon (there are three teaspoons in one tablespoon).

  I do not know how wheat dextrin compares to guar gum as a soluble fiber 
supplement for Irritable Bowel Syndrome. I would not assume that the wheat 
dextrin in Benefiber is safe for people with wheat allergies or gluten 
intolerance disorders such as celiac.
