How to Use Benefiber

Benefiber is a powdered fiber supplement that dissolves in liquid. Fiber supplements help people who don't get enough fiber from regular food intake to meet minimum nutritional amounts. Since Americans consume about half the American Dietetic Association's recommended 20 to 35 grams of dietary fiber per day, fiber supplements such as Benefiber offer an easy and convenient way to add some fiber without having to eat more food.

Measure out your dose. The recommended dose of Benefiber varies depending on age. For ages 12 and up, the dose is 1.5 to 3 tsp. Ages 7 to 11 should take 1 to 1.5 tsp. For ages 6 and under, talk to your doctor about Benefiber dosage.

Decide what to mix the Benefiber into. Benefiber dissolves into liquid. Choose any beverage, or a soft food such as pudding or applesauce. Carbonated beverages are not good at dissolving Benefiber, so try to avoid using any soft drinks for taking your Benefiber.

Pour the beverage or soft food into a cup or bowl. Then add the Benefiber powder. This prevents fiber from getting stuck at the bottom of the dish.

Mix well. Using a spoon, stir the food or drink well to make sure the Benefiber is distributed evenly in the liquid. You don't want a gritty taste, and that grit comes with poorly blended Benefiber.

Drink it all. You have to drink the entire beverage or eat all the food in order to get your full dosage. Eat or drink it to the last drop.

Repeat. You can take up to three doses of Benefiber a day. Repeat steps 1 through 5 for every dose of Benefiber you take.


When starting fiber supplements, don't start on the maximum dose. Start with a low dose, and gradually work your way up to the amount you need. Adding too much fiber at once causes gastrointestinal discomfort and constipation.
