Gastroenterologist recommended.

Gastroenterologist recommended Benefiber, by brand name, several years ago. Sam's Club price delivers the best value.

Keeps me regular

Love this. Benefiber is very gentle and not hard like other brand. I add one teaspoon to my morning coffee

Dissolves Completely

I love that this fiber dissolves completely when mixed with water and it has no bad taste whatsoever. Love it!

Fiber

I didn't realize it works; by giving soft fiber bulk when you have to treat your intestine with kindness. Mine by prescription.

Benefiber Daily Prebiotic Fiber

Does what it is supposed to do. Has no flavor so I put it in my coffee in the morning.
