The 6 best fiber supplements for healthy digestion

Fiber is an essential carbohydrate that helps the body regulate sugars, appetite and digestion. Fiber is important, but it is estimated that only 5% of people consume the recommended amount of fiber daily.

Fiber supplements meet your nutritional needs while regulating digestion, preventing constipation, and managing glucose and cholesterol levels. There are two types of fiber in supplements: soluble fiber and insoluble fiber. Soluble fiber dissolves in water and helps lower blood sugar and cholesterol levels. Insoluble fiber is the type that helps move food through the digestive system.

If you’ve been looking for a fiber supplement, you’ve come to the right place. Here are our picks for the six best fiber supplements that will keep your gut happy.

Frequently asked questions about fiber

Fiber is an essential carbohydrate that our body uses to manage sugars, appetite and body digestion. Our bodies cannot break down fiber, so it passes through our digestive system undigested. This adds weight and softens the stool, making it easier to pass.

Fiber-dense foods:

  • Beans
  • Edamame
  • Berries, pears, apples
  • Brussels sprouts and broccoli
  • chia seeds
  • Carrots and beets
  • Quinoa
  • oats

Although fiber is present in so many foods, many people do not get enough of it from their diet. This is where fiber supplements come in.

How often should you take fiber supplements?

Fiber supplements are generally considered safe for daily use. But you should only take them if you don’t get enough fiber from your food.

However, there are side effects of fiber supplements that should not be ignored. Your fiber supplement can cause constipation if you take too much too quickly or if you don’t drink enough water. When starting fiber supplements, it’s best to start slowly and at a lower dose, then work your way up.
