Only 5 percent of adults consume the recommended level of dietary fiber. Choosing the best fiber supplement can help you get the fiber you need for a healthier, happier life.

Without enough fiber, you might experience problems ranging from constipation to weight gain. Fiber is an important part of the human diet, and has been for thousands of years. However, modern diets often lack the whole grains, veggies, and fruits that provide crucial fiber sources.

If you’ve been gaining weight, feeling sluggish or tired, or simply not eating healthy enough lately, it’s time to invest in the best fiber supplement for you. Everyone’s health needs are different, and choosing the best supplement depends on the individual. That’s why we’ve highlighted a wide variety of powerful supplements here -- keep reading to choose the best one for you.


Everything You Need to Know About the Best Fiber Supplement

In a perfect world, everyone would get the fiber they need from the food they eat. But a high-quality supplement can make up for what your diet might be lacking. What sets some supplements apart from the rest?

First, make sure to check the sugar content of your fiber supplements. While it’s great to use a flavored supplement that tastes good, some of them come with more sugar than you should have. Look for sugar-free or low-sugar options instead. You can also take unflavored products, like pills, to avoid sugar altogether.

Also, make sure to check the source of the fiber in your supplements. Some people prefer natural sources, while others might have a sensitivity to some fiber sources, like wheat. It’s important to know what’s in your supplements.

Finally, soluble and insoluble fiber supplements work a bit differently. Soluble fiber is best for people with issues like irritable bowel syndrome, while insoluble fiber works well to combat constipation.

How We Reviewed

To put together our list of the best fiber supplement options, we focused on variety. Different fiber forms and sources work better for different people. You’ll find just about every type of fiber supplement the market has to offer represented on this list.

We also looked at consumer ratings, as well as prices, to choose the best supplements to feature. High ratings are important, but fiber supplements also don’t need to break the bank.

Overall Price of Fiber Supplements

The sources of fiber in supplements, like wheat or psyllium husks, don’t cost much. So there’s no reason for fiber supplements to cost much, either.

Your body doesn’t store fiber for future use. Fiber simply helps your digestive tract work better. While this task is important, it doesn’t make sense to pay a lot for something that’s just going to move through your digestive system.

You can try most fiber supplements for a very low price, making it very cost effective to test out a few things until you find out what works for you. High prices rarely translate to higher quality in the world of fiber supplements, so avoid anything that costs you a lot (unless you’re looking for specific specialty ingredients).

Our Verdict

Are you getting enough fiber in your diet? If you’re not sure, it might be time to find the best fiber supplement for you.

Dietary fiber intakes among adults in the United States average about 15 grams a day. However, most adults need 25 to 30 grams of fiber a day for optimum health. Doubling your fiber intake from food alone can prove difficult, so use fiber supplements to give you a boost.

While we’d love to tell you the single best fiber supplement, the truth is that it depends on your unique health needs. The fiber source that works for one person might trigger sensitivities in another. Some people may love taking fiber gummies, while others prefer a simple capsule form. We’d suggest trying less expensive options first, though, and trying the pricey ones only if those don’t work.
