Many people have a strong opinion about fiber supplements (and electrolyte supplements). They think that they’ve not been proven to be beneficial for the health and that they are a waste of money. But they take them anyway, people say. There are lot of claims about what they can improve and cure, from helping with constipation, gas, abdominal pain, irregular bowel movements and even helping weight loss and reducing cholesterol levels.

So are they useless? Is taking a fiber supplement worth it? Or they are harmful?

No need to reach conclusions on that. Let’s take a look at the facts.

What is fiber?

Fiber is the part of plant foods that your body can’t digest. It can be found in all fruits, grains, veggies, and most kinds of nuts. But did you know that fiber is also present in animals, too? In fact, fiber comes in three primary forms — soluble, insoluble and resistant.

Soluble fiber forms a gel or a paste when it encounters water. Basically, this type of fiber absorbs water. You will find soluble fiber in bananas, green peas, carrots and oatmeal. This fiber helps with constipation, diarrhea, irritable bowel syndrome and can even lower cholesterol.

1. Metamucil Fiber Thins

Our rating: 9 / 10

Metamucil Fiber Thins

Check Price on Amazon

Pros:

  • Does the job
  • Sweetened with non-GMO erythritol
  • Fantastic texture
  • Soft and chewy
  • Standard Metamucil taste

Looking for an alternative to highly sugary fiber bars? You may prefer something that offers the same health benefits but less sweet. That’s where the Metamucil’s Sugar Free Fiber Snacks come in.

The sugar free snack bar comes in at 100 calories for each serving, with 3 grams of fiber. The fiber is derived from psyllium husk. The bar is made with organic erythritol, a sugar alcohol.

The texture is very similar to the original Metamucil fiber bar, minus all the extra sugar. In our opinion, the taste is preferable to the original version because they only sweeten this one with erythritol.

Metamucil’s fiber supplement is made to address a variety of ailments such as digestive and bowel problems, and works to alleviate both constipation and diarrhea.

The psyllium fiber alone is not as effective as it is when paired with the methylcellulose, so to get the maximum benefits of these two supplements, they should be taken together as directed by your doctor or nutritionist.

Your microbiome is your gut flora, a collection of trillions of beneficial bacteria and other microbes. This microbiome is constantly interacting with the food and drink your body takes in, as well as its environment. Healthy people have trillions of bacteria happily living and working in the gut, eating the food we consume and keeping harmful bacteria from taking hold.

When the microbiome is out of balance, a variety of things can happen, from serious gastrointestinal problems to simply making you feel “off.” It’s estimated that 80 percent of your immune system lives in your gut. Increased levels of inflammation in the gut correlates with an increased level of inflammation in the body.

6. Pure for Men

Pure for Men

Check Price on Amazon

Pros:

  • Vegan
  • Multipurpose
  • Can be taken daily or when needed
  • No Side effects

The only fiber supplement that is 100% natural, without side effects, developed for men and women. Ingredients: psyllium husk, apple pectin, hazelnuts, guarana, calcium, potassium, folic acid, psyllium husk and vitamins B and C.

We have tested a few crowd-sourced fibers, and our results were slightly mixed:

WishGarden Herbal Fiber was the top fiber we tested. The pills are huge, and give a pretty uncomfortable texture for the first 10-15 minutes of taking (akin to drinking oatmeal). The texture in our experience didn’t last beyond that, but left us with a feeling of fullness and less antsy on our next hunt for food. We still felt hungry, but just a different kind of hungry. Fiber also takes a few hours to hit you, so don’t expect any change right away.

Once you mix it with a liquid or food, it will absorb water and expand in your stomach, which will help to slow down your digestion.

A fiber supplement can help you add more fiber to your diet. Fiber supports digestion, balances blood sugar levels and is the texture of fruit and veggies. You can quickly get fiber with a fiber supplement.

Fiber is defined as any material that is indigestible by the human body. The most common fiber supplements are made from plant sources, such as psyllium seed husks.

Psyllium seed husks can be taken as a supplement because they produce a gel-like substance when they come in contact with water. This gel, which can form a soft, bulk-forming stool, can be helpful for people with constipation.

These fiber gummy bears do boast a lot of powerful nutrients. They’re completely vegan and sugar free. They’re also gluten free. They do contain a lot of fiber though, so if you’re taking this supplement you should drink a lot more water than usual. If you drink a lot of soda, juice or beer, you might want to stay away from this fiber supplement, because it will cause serious bloating! If you’re a running, and you have too much of this in your system, you could also experience some GI problems.

Psyllium Husk Capsules

Pros:

  • No need to travel to the restroom
  • Stays in your stomach a long time
  • High fiber content

Cons:

  • Mouth-filling taste
  • Can cause cramps

Fiber fills you up, so some people use it to lose weight. Because our bodies can’t digest fiber, it passes through the digestive tract relatively untouched to be eliminated in the form of stool. With sufficient fiber in your diet, you can think about food less because it’s not as likely to stick with you, and you may end up eating less.

We really like this psyllium husk supplement because it’s made from 100% natural fiber. This means you don’t have to worry about extra chemicals, preservatives or additives, and that you can take it without any judgment from a healthcare professional.

We also like that it’s made from one ingredient and sourced from the USA.

Frequently Asked Questions (FAQ)

What is the most effective fiber supplement?

The most effective fiber supplement for general well being is psyllium husk. Psyllium husk has soluble and insoluble fiber. It is considered high fiber because it absorbs a lot of liquid and expands once ingested, but its effect is not as significant as a sugar-free diet where fiber intake is a conscious daily effort.

Fiber intake is mostly beneficial for those with high cholesterol, intestinal problems or for those who cannot tolerate sugar. In any case, a fiber supplement should not be your only source of dietary fiber but rather, should be used in addition to your daily diet.

Do fiber pills really work?

Yes! Fiber supplements do work. Actually, the modern medical community has studied fiber supplements in great depth and is particularly convinced that soluble forms increase gut health and can alleviate constipation. Gastrointestinal Function is an extremely important system in your body, as it affects overall well-being. Having a healthy gastrointestinal system can help prevent irritable bowel syndrome, heart disease, and even some forms of cancer. Hence, taking fiber supplements is certainly an effective way of improving the function of this incredibly important system.

Which form of Metamucil is best?

Metamucil comes in several forms, all of them servings of Psyllium husk fiber. The most popular option is the original flavor of Metamucil, which has a strong, unpleasant taste similar to lemon lemongrass. The best way to sweeten the original and the natural varieties is to mix it with fruit juice. The product comes in slightly different shapes and sizes, including those designed for travel and weight loss.

While all Metamucil products do contain the same active ingredient, there are slight differences between varieties, including fiber density. If you’re interested in trying a variety other than the original, we’d recommend the naturals variety. The naturals variety is less sweet than the original, but it has a milder flavor. Anyone who doesn’t enjoy a strong taste will appreciate this option.

What is the best fiber supplement for constipation?

Dietary fiber is an important part of healthy digestive system and overall good health. Dietary fiber is a type of carbohydrate that is partly or fully indigestible by our bodies. The useful fiber supports the growth of healthy bacteria in our large bowels. Food fibers range from the very soluble ones (like hibiscus) to the very insoluble ones (glucomannan).

While research shows that it is generally smart to consume between 20-30 grams of fiber per day, there are few exceptions when you need to increase your fiber intake. For some people, the consumption of high-fiber diets is more beneficial, while, for others, it has no positive effects. In these cases, they can supplement the necessary fiber amounts using fiber supplements.

A fiber supplement is made of any soluble fiber. Soluble fiber can be either a mixture of soluble and insoluble fibers, or it can be any one kind only, soluble or insoluble.

Conclusion

As with almost every benefit of nature, care has to be taken in how these are consumed. Huge benefits are nullified if deficiencies are not avoided. One of the most important nutrients we are likely to neglect is fiber. Fiber is one of the most important additions to diet because of its role in digestion as well as nutrient absorption.
