If you purchase something mentioned in this article, we may earn a small commission.With a whopping 95% of the U.S. population1 failing to get adequate fiber in their diet each day, the average American faces a serious fiber gap. Loading up your plate with fiber-rich foods (like fruits, veggies, whole grains, legumes, and seeds) at every meal is critical—and most will still struggle to meet their daily fiber needs.
"Most Americans do need to consume more fiber every day," says food science and nutrition professor at the University of Minnesota Joanne Slavin, Ph.D., R.D. "Since the recommended intake for fiber is 28 grams per day and most folks only consume around 16 grams, there may be a need for supplements."
Adding a high-quality fiber supplement with an efficacious dose of plant fiber to your daily routine can help you achieve your daily fiber goals to promote gut health, immune function, digestion, blood sugar balance, healthy bowel movements, and more.*

Found exclusively in plants, fiber is a unique complex carbohydrate that doesn't break down in the digestive tract. Instead, it passes through the body undigested, making it an excellent "internal sweeper" for waste.*
There are two types of fiber: Soluble fiber dissolves into a gel during digestion that helps collect and remove unwanted toxins, cholesterol, and extra hormones, while insoluble adds to and forms the bulk of stool (i.e., it supports the motility and evacuation of poop).
While they can be found in capsule, tablet, and gummy form, most of the fiber supplements you'll find online and in stores are sold in a powder format.

How to choose a fiber supplement.
Shopping for a fiber supplement can be overwhelming, to say the least. First and foremost, you should look for efficacious doses of dietary fiber from science-backed ingredients clinically shown to deliver your desired health benefits (like those on this vetted list).
Adding more fiber to your diet can help balance your mood, enhance your gut health, support a healthy body composition, bolster your immune system, aid in digestion, and promote healthy bowel movements and regularity.* Look for a tailored formula that includes an effective dose of fiber and supports the area of health you're looking to improve.
Lastly, it's important to consult your health care provider before adding any new supplement to your routine.
Benefits of fiber.
As you can see from our product list of best fiber supplements, dietary fiber supports myriad areas of health.
It's most famous for its gut health and poop benefits—i.e., supporting a diverse and abundant gut microbiome, increasing bowel transit time, promoting regularity, aiding in stool formation and gut motility, and bolstering gut immunity and intestinal barrier function.* However, fiber also promotes a healthy immune response, delivers mood balance by supporting the gut-brain axis, supports metabolic health factors (e.g., blood sugar balance, healthy cholesterol levels, appetite regulation), and aids natural detox pathways.*
The takeaway.
Fiber makes healthy digestion, regularity, and bowel movements possible—and most Americans aren't getting nearly enough.* In addition to a well-balanced diet filled with fiber-rich plant foods, a daily fiber supplement can help you further address your daily needs and fully bridge the fiber gap.*
