The 25 Top-Rated Fiber Supplements for Digestive Health

The benefits of fiber aren’t lost on most people; however, many people don’t realize that most adults in the U.S. don’t get nearly enough of it each day. The average fiber intake in the U.S. is about 15 grams each day, but the currently recommended amount is twice that – 30 grams every day (specific recommendations vary for men and women of different ages). While it’s best if you get most of your daily fiber intake from your diet, supplements can help to reduce the unwanted effects of not consuming enough dietary fiber.

You may be one of the lucky few who experience few (or no) ill effects from a lack of dietary fiber, but most people aren’t so lucky. Even if you don’t notice any negative health effects from a lack of fiber, it can have long-term health consequences. Fiber can help to reduce cholesterol, maintain bowel health, regulate your weight, and even help to control blood sugar levels. In other words, you don’t want to brush off your fiber intake as inconsequential.

For those who struggle to get enough fiber from their daily diets and those who rely on fiber supplements to help regulate conditions such as IBS (Irritable Bowel Syndrome) or chronic constipation, we rounded up 25 of the top-rated fiber supplements to help you make a smart decision for your health. The 25 top-rated fiber supplements listed below (in alphabetical order) include fiber supplements for kids (yes, kids need fiber, too!), powders, capsules, and even brownies that can help you reach your daily fiber goals.

Note that the information below regarding the benefits of each product are based on claims made by the manufacturer. As with any supplement, it’s recommended that you discuss your options with your healthcare provider, and always carefully evaluate nutritional labels before use.
