8 of the Best Fiber Supplements, According to a Dietitian

Fiber plays a crucial role in maintaining a healthy diet, yet many people struggle to get enough of it in their daily meals. The average American only consumes about half of the recommended daily amount of fiber, which is 25-30 grams per day. That’s where fiber supplements can come in handy.

Not all fiber supplements are created equal, however. Some may be more effective than others at improving digestion, reducing cholesterol levels, and aiding weight loss. To help you choose the right one, we spoke with a registered dietitian to determine which fiber supplements are the best on the market.

Whether you’re looking for a powder, pill, or gummy, there’s a fiber supplement out there that’s right for you. Below are eight of the best options recommended by our dietitian expert.

Why Fiber is Important for Your Health

What is Fiber?

Fiber is a type of carbohydrate that the body cannot digest. It is found in plant-based foods such as fruits, vegetables, whole grains, nuts, and seeds.

Fiber can be divided into two main types:

  • Soluble fiber: This type of fiber dissolves in water and forms a gel-like substance in the intestines. It can help lower cholesterol levels and improve blood sugar control.
  • Insoluble fiber: This type of fiber does not dissolve in water and adds bulk to the stool. It helps regulate bowel movements and prevent constipation.

The Benefits of Fiber

Fiber offers a wide range of health benefits, including:

  • Lowering cholesterol levels: Soluble fiber can bind to cholesterol and help the body eliminate it.
  • Improving digestion: Insoluble fiber adds bulk to the stool, helping to promote regular bowel movements and prevent constipation.
  • Reducing the risk of developing chronic diseases: Fiber intake has been linked to a reduced risk of several chronic diseases, including heart disease, diabetes, and certain types of cancer.

How Much Fiber Do You Need?

The recommended daily intake of fiber is 25 grams per day for women and 38 grams per day for men. However, most Americans do not consume enough fiber in their diets.

The best way to increase fiber intake is to include more fiber-rich foods in your diet, such as:

  • Whole grains – brown rice, quinoa, whole wheat bread
  • Fruits – berries, oranges, apples, pears
  • Vegetables – broccoli, carrots, spinach, kale
  • Nuts and seeds – almonds, chia seeds, flaxseeds, pumpkin seeds

If you are unable to meet your daily fiber needs through diet alone, fiber supplements can be a helpful option. Talk to your doctor or a registered dietitian before taking any supplements.

How to Choose a Fiber Supplement

1. Consider your dietary needs

Before choosing a fiber supplement, it’s important to consider your specific dietary needs. If you already eat a high-fiber diet, you may only need a supplement with a small amount of fiber. However, if you struggle to meet your daily fiber intake, opt for a supplement with a higher fiber content.

2. Examine the type of fiber

Fiber supplements come in different forms, such as psyllium, glucomannan, methylcellulose, and inulin. Each type of fiber has unique properties that can provide different health benefits. For example, psyllium supplements can help regulate blood sugar levels, while glucomannan supplements can aid in weight loss.

3. Check for added ingredients

Some fiber supplements may contain added ingredients, such as artificial sweeteners or flavors. It’s important to check the ingredient list to ensure that you are not consuming any unwanted ingredients that could negatively affect your health.

4. Evaluate the form of the supplement

Fiber supplements come in various forms including powder, capsules, and chewable tablets. If you have difficulty swallowing pills, a powder or chewable supplement may be a better option for you. Checking the form of the supplement is important to ensure that you are able to consume it comfortably.
