In previous years, Benefiber, a nutritional supplement not certified as Kosher for Passover, contained neither chometz nor kitniyos.

However, the situation has changed and some forms of Benefiber are now made with “wheat dextrin”, which is chometz.

Currently Retail Benefiber contains actual chometz (chometz gamur) and can neither be consumed nor owned on Pesach.

Institutional Benefiber does not contain chometz or kitniyos, however it is not certified as Kosher for Passover.

If you need to use Benefiber over Passover, it is best to obtain the institutional Benefiber. Institutional Benefiber can easily be identified by the inclusion of “guar gum” in the ingredients as opposed to “wheat dextrin”.

Finally, not all Benefiber products are certified Kosher by the Orthodox Union. Those certified as OU Kosher Pareve will bear an OU symbol on the label.
