Fiber supplements are used daily for various reasons. Whether to ease constipation, promote gut health, or support weight loss, there are so many to choose from that picking a fiber supplement can feel a little overwhelming. But fear not; in this article, we’re going to help you find the right one for you.

Getting adequate fiber means eating as many fiber types and fiber-rich food sources as possible. This means eating more fruits, vegetables, whole grains, nuts, and seeds. Many plant foods contain lots of fiber, and adding more fiber to your diet is an excellent way to boost weight loss.

However, some people may find it difficult to get more fiber in their diet. In these cases, a supplement can be incredibly useful. There are a few different kinds of supplements, including powders and capsule forms. Some help to treat constipation, and others can be used daily to boost your overall health. We’ve taken a look at all different kinds in this article.

7 Best Fiber Supplements for Weight Loss

Below, we’ve summarized the pros, cons, and key features of each of our top 7 fiber supplements for weight loss. Check it all out to find out more about each fiber supplement and choose the one that is right for you.

  • Aids combat constipation
  • Boosts energy and cleanses the gut

Our Rating:

4.5

ColonBroom is a psyllium husk-based fiber supplement used to improve digestive health, ease constipation and bloating, increase metabolism, cleanse the gut, and support overall weight loss.

This supplement has a great strawberry taste and is offered to customers alongside a personalized diet guidebook. This guidebook offers handy tips and tricks and helps customers understand how to lose weight and keep it off. The product is also delivered free in the US.

ColonBroom doesn’t have any artificial ingredients, so you can be sure it is healthy and doesn’t have any additives that might compromise your weight loss journey. Moreover, this supplement is not a laxative, not habit-forming, and might even help with reflux and other digestive issues.

Insoluble fiber, such as psyllium husk, regulates blood sugar and cholesterol while reducing cravings and boosting metabolic processes in your body. This means you can lose weight faster.

ColonBroom requires two daily doses. To take this fiber supplement, you simply add the solution to a glass of water and drink it twice a day. If you’re taking this supplement for constipation, you’ll see results within 24–72 hours.

  • Promotes better digestive health
Our Rating:
stars
4.2

Metamucil fiber supplements are designed to increase your fiber intake and are suitable for those who may not get enough dietary fiber. The fiber in these supplements is a mix of soluble fiber and insoluble fiber, coming from psyllium husk and dried Plantago ovata seed, the same as in ColonBroom.

Metamucil is also useful in supporting appetite control. It can help you feel fuller for longer, helping you eat less and, therefore, enforcing a calorie deficit, meaning this psyllium fiber powder may be good for weight control.

Other benefits of the Metamucil supplement include lowering cholesterol levels, which support better overall heart health. Psyllium husk in this supplement may also be good for blood glucose management, offering better blood glucose regulation.

#3 Benefiber

  • Promotes good gut health and nourishes gut bacteria
  • Benefiber’s fiber source is completely plant-based
Our Rating:
stars
3

Benefiber is a prebiotic fiber supplement designed to boost the health of your digestive system by nourishing your gut bacteria. It is a plant-based fiber supplement that dissolves in beverages and food. A daily dose requires adding one scoop to a drink or food product three times a day.

The main goal of Benefiber is to support better colon health. It may also work to reduce cholesterol levels in users, but more research is needed. The formula helps feed gut flora and ensure it is in good condition.

While it is not specifically designed for weight loss, Benefiber may help support better weight control. Adding more prebiotic fiber to your diet can help you feel fuller for longer and may induce appetite control. This can help you eat less throughout the day, creating a calorie deficit and promoting weight loss.

#4 FiberCon

FiberCon
  • Contains insoluble fiber
  • Easy to use
  • Used to treat bouts of constipation
Our Rating:
stars
3.9

FiberCon is a bulk-forming fiber therapy that helps soften your stools and treats bouts of constipation. FiberCon contains insoluble fiber and comes in an easy-to-swallow pill. This fiber supplement promises to cause a bowel movement within 12–72 hours if the product is being taken to treat constipation.

FiberCon is not a carbohydrate-based supplement and is therefore suitable for use on the ketogenic diet and an intermittent fasting regime. It needs to be taken twice daily and should be taken for between 1–3 days, depending on your symptoms. It is not advised you take this supplement for any longer than 7 days.

Though bulk-forming laxatives can help you lose weight, there are dangers to using them for long periods. These laxatives can cause electrolyte imbalances and dehydration. It is not advisable to use laxatives as a long-term solution for weight loss.

#5 Citrucel

Citrucel
  • Made from 100% soluble fiber, namely Methylcellulose fiber
  • Comes in powdered and caplet format
Our Rating:
stars
3.8

Citrucel is a fiber therapy that claims not to give users the normal side effects of taking fiber, like gas and bloating. It uses 100% soluble fiber to help get things moving again, using a form called methylcellulose fiber.

Citrucel comes in several product options, including an orange mix, sugar-free options, and pills. The product is taken by adding a scoop of the mixture to a glass of water. You can take up to 3 doses each day as needed. Four pills are equal to a scoop of powder.

Citrucel is not specifically designed for weight loss. It is specifically stated that the supplements are used to treat occasional constipation and irregularity. The product is described as a bulk-forming laxative.

There is some research that suggests soluble fiber can slow the emptying of the stomach, prolonging fullness and reducing your appetite. This means this supplement could support weight loss. However, as a bulk-forming laxative, it is not advisable to use it as a long-term solution for weight loss.

Garden of Life Organic Fiber
  • Prebiotic-formulated organic fiber
  • Added superfoods
  • Supports healthy gut flora
  • 5 grams of fiber per serving to be taken daily
Our Rating:
stars
4.2

The Garden of Life Organic Fiber supplement uses a prebiotic form of fiber mixed with other superfoods and comes in both citrus and unflavored options. It is free from psyllium husk as well as dairy, soy, added sugar, and filler ingredients.

One teaspoon of this powdered supplement, dissolved into a glass of water, is meant to feed your gut bacteria and promote healthy digestive function. It also adds good bacteria to support a healthy microbiome.

Taking this fiber powder could also help make you feel fuller for longer and promote appetitive control. As it is fiber-based, it should not break a fast and could be used during long fasting periods on an intermittent fasting diet, like the OMAD method. Supplements like this can help you fast for longer.

There is research that suggests that prebiotic fiber may play a role in increased fat loss. It is understood that the gut microbiota has a major impact on weight loss, and as such, keeping it as healthy as possible could increase fat metabolism.

#7 Vitafusion Fiber Well

Vitafusion Fiber Well
  • Ups the amount of fiber you get daily
  • Gummy format
  • Added B vitamins for energy support
Our Rating:
stars
3.5

The Vitafusion Fiber Gummies offer 5g of fiber per serving and come in three different flavors: natural peach, strawberry, and blackberry. These fiber gummies are sugar-free and come with added B vitamins to enhance your overall health and give your energy levels a boost.

These gummies can be taken to up the amount of fiber you get per day, but they may also be useful for weight loss. Fiber consumption can make you feel fuller for longer and supports appetite control, both of which help you eat less throughout the day. Though gummies are easy to consume and could be good for children, they tend to be high in sugar.

These gummies may also be used during extended fasting on an intermittent fasting diet, like the 20:4 method, to help you feel fuller throughout your fast and stop hunger pangs.

The addition of B vitamins to these gummies could support weight loss. There is evidence to suggest that B vitamins play a role in increased fat metabolism and weight reduction. Though this study was carried out on rats, there is a potential benefit for human health.

A Word From a Nutritionist

Fiber is an important macronutrient in the body, and there are two different kinds you can get in your diet: soluble fiber and insoluble fiber. Both of these kinds of fiber work in different ways in the body, and both promote good digestive function.

While there are many fiber-rich foods, like fruits, vegetables, and whole grains, you can also add a fiber supplement to your diet to boost your overall intake. A fiber supplement can help promote a healthier digestive system, and it could treat constipation. Additionally, fiber supplements may promote weight loss.

Fiber supplements can help with weight loss by helping users feel fuller for longer, increase appetite control, and could help regulate blood sugar levels better. Fiber supplements can contain both soluble and insoluble fiber.

Soluble fiber is water-soluble and helps create soft and bulky stools. You will find soluble fiber in oats, peas, beans, and psyllium husk, which is a common ingredient in fiber supplements.

Insoluble fiber is not water-soluble, unlike soluble fiber. Insoluble fiber essentially acts as a sweeping brush in the colon. It moves stool along the intestines and out of the body. Insoluble fiber is found in whole wheat, wheat bran, nuts, and beans.

The best fiber supplements can help with weight management as well as many other things. They can ensure you have regular, soft, and bulky stools to help you avoid constipation and other digestive problems.

They could also help improve your blood sugar levels and reduce your cholesterol levels.

Most fiber supplements come in powdered or capsule form, making them very easy to take daily. Ensure you understand how much fiber you will get per serving and whether this is enough. It is important to note that you may have some side effects as you begin taking your fiber supplement while your body gets used to the increased intake.

Conclusion

Taking a supplement to increase the amount of fiber you get daily is an easy way of staying healthy and supporting appetite control. Fiber can help you feel fuller for longer, ensuring you eat fewer calories each day.

There are many different supplement types on the market, so it can feel a little overwhelming to choose one. We have taken a look at seven in this article, but our top choice has to be ColonBroom.

This powdered supplement has a great strawberry taste and supports better appetite control along with increased metabolism, better body detoxification, and even better skin, hair, and nails. It’s an all-around supplement that will work perfectly for your weight management goals.
