Frequently Asked Questions About Fiber Supplements

What is Fiber?

Fiber is a plant-based carbohydrate that can not be broken down or digested. It is sometimes called roughage because it is a tough and sturdy filament that the body cannot digest.

In this guide, we are referring to dietary fiber rather than textile fibers.

Fiber passes through the digestive tract more or less unscathed. There are two types of dietary fiber, and they react differently to digestion. These fibers include soluble fiber and insoluble fiber.

Soluble fiber refers to fiber that is water-soluble and, when digested, does change form but is not absorbed by the body. It becomes a gel-like mass in the intestines and is later excreted as waste.

Insoluble fiber does not change form, and remains intact throughout the digestive process.

Soluble fiber can be found naturally in legumes in high concentrations. These include foods such as black beans, kidney beans, navy beans, lentils, peanuts, and peas.

Oats and grains also contain a healthy soluble fiber dose, as well as some fruits and vegetables. Brussels sprouts are one of the best natural sources of soluble fiber.

Insoluble fiber can be found naturally in many seeds, and the skins of certain plant products such as the outer husk of corn kernels, grape skins, and the skins of peas. Insoluble fiber can also be found in whole grains and wheat bran. Dried fruit is also a great source of insoluble fiber.

What Are Fiber Supplements?

In America, 97% of the population is deficient in dietary fiber, so odds are, you are one of them.

Fiber supplements are concentrated forms of fiber that you can take to supplement your daily intake of fiber.

These supplements can come in multiple forms, such as capsules, tablets, gummies, and powders.

There are different types of fiber supplements that are available on the market today. Different forms may have slightly different benefits and may suit one person better than another.

Some of these different forms of fiber supplements include:

  • Inulin – Inulin is a prebiotic form of fiber.
  • Methylcellulose – Methylcellulose is a soluble fiber made from cellulose or the cell walls of plants. Methylcellulose.
  • Lignan – Lignan is an extracted natural fiber, called a polyphenol, that is found in plant cells. Lignans are naturally found in seeds, fruits, vegetables, and some whole grains.
  • Cellulose – Cellulose is an extremely tough insoluble fiber, and can be found in wood, paper, and cotton, as well as in all plant-based foods. Cellulose provides a plant with structural integrity.
  • Pectin – Pectin is a soluble fiber that is extracted from fruits, vegetables, and seeds.
  • Gum – Gums are sugars that are found in seeds that are also soluble fibers.
  • PsylliumPsyllium increases satiety and slows digestion, and is made of 70% soluble fiber. Psyllium comes from the seeds of the Plantago ovata plant.
  • Dextrin – Dextrin is a soluble fiber that is produced from the hydrolysis of starches. It can also be described as a low molecular weight carbohydrate.

Other forms of fiber products exist, and some use fiber straight from certain foods such as oat fiber or beet fiber. Our list above covers the most common forms of fiber that you will see on the labels of fiber supplements that may not be as easily identifiable.

Who Can Benefit from Fiber?

Considering that most of the population does not get enough fiber, most people could benefit from adding a fiber supplement.

With that said, there are certain groups that may notice more benefit than others, such as:

  • Those who are or may become fiber deficient – Only 3% of Americans are consuming enough fiber in their diets, while 97% are at risk of deficiency, or deficient. Without the proper fiber dosage, your body is more prone to heart disease, stroke, and weight loss. You are more likely to become constipated, overeat, and increase your levels of bad cholesterol, and reduce your energy levels. You may also develop type II diabetes.
  • Those who suffer from constipation – Constipation is a condition in which bowel movements are painful or they do not occur frequently enough. Constipation is more serious after three days without a bowel movement, because stool begins to harden, which makes it difficult to pass. Fiber helps constipation in a couple of ways. Soluble fiber retains water in your stool, making it softer and easier to pass, while insoluble fiber adds bulk to the stool. This improves the speed at which stool will pass through your intestines.
  • Those with irregular bowel movements – A regular bowel movement occurs at least once daily, with a strong urge to defecate, with stools that are relatively small volume and size, and that are easy to pass. Anything that does not fall within these characteristics is considered an irregular bowel movement. Irritable bowel syndrome (IBS) and fecal incontinence are some common irregularities, but a range of irregularities can occur. Fiber is one of the most important substances for IBS and healthy bowel movement.
  • Those with inflammatory bowel disease (IBD) – Inflammatory Bowel Disease is an umbrella term for two different bowel diseases that involve inflammation. These diseases include Crohn’s disease and ulcerative colitis. Crohn’s disease is rare and usually affects the lower part of the small intestines. Symptoms include fever, bleeding from the rectum, and diarrhea. It is not curable and causes are still unknown, but research suggests it may be caused by genetics or abnormal immune system processes. Ulcerative colitis also cannot be cured, and it causes inflammation and ulcers throughout the entire digestive tract.
  • Those with type II diabetesDiabetes is a range of metabolic diseases identified by a lack of insulin or insulin resistance. Type II diabetes is not genetic, is marked by insulin resistance, and generally occurs later in life. Type II diabetes is often caused by long term overeating, which overworks the pancreas, the gland that produces insulin. After the body quickly takes in large amounts of glucose from sugary or processed foods, the pancreas produces lots of insulin, and cells may start to become resistant to insulin – which in the long run, can lead to increased risk of developing type II diabetes.
  • Those with high blood pressure – High blood pressure is a condition in which blood forces too much pressure on artery walls. Risk factors for developing high blood pressure include being overweight, smoking, taking in too much dietary salt, drinking too much alcohol, smoking, and stress. Genetic factors also play a role. Over 25 studies have concluded that having a diet high in fiber can help blood pressure.
  • Those who are or may become overweight – Fiber may improve weight loss efforts (although it does not work in the same way a strong fat cutting product would). Weight gain happens when the body takes in too much glucose at once. This can happen from a day of overeating, or it can happen when consuming foods that are full of sugar or refined carbohydrates. Sugar and refined carbohydrates without fiber are basically straight shots of sugar to the metabolism, which causes the body to produce fat. When fiber exists in the diet, it slows down the breakdown of food into glucose, resulting in a steady stream of sugar through the metabolism. With fiber, your body is less likely to produce excess fat.

Are There Any Side Effects of Fiber?

Fiber supplements may cause gas or bloat in some people. This can be prevented by gradually increasing your fiber dosage instead of taking a large dose initially. If your body is not used to having lots of fiber, then shocking your system with a large dose may cause gas.

Some forms of fiber are non-fermentable as well, meaning that they do not ferment in the digestive system and therefore do not produce gas. If you have problems with gas already, choosing a fiber supplement such as methylcellulose to start may prevent gas.

How Do I Pick a Good Fiber Product?

Finding the right fiber supplement for you means reading the labels, researching manufacturers, and understanding the fiber dosage you need. As a consumer, it is important to be aware of what is in your product, who makes it, and how much of it you are getting. All of these factors can help you find the best fiber supplement at a reasonable price.

The label of a good product should be transparent. This means that you should easily be able to tell what type of fiber is being used. For example, if the product uses a fiber blend, the forms of fiber used should be listed on the label and the amount of fiber per serving should also be listed. Fiber blends are actually better than using a single form of fiber, because blends often provide both soluble and insoluble fibers.

Researching the company or manufacturer is another important factor in the decision. Not all brands are created equal. Learn about the company’s reputation and their manufacturing facilities. Ensure that their manufacturing facilities are Good Manufacturing Practices (GMP) certified by an accredited third-party such as NSF, or possess other certifications of the sort.
