Best Fiber Supplement for Weight Loss: Top 7 to Try in 2023
Dietary fiber is an essential macronutrient in every diet.
It keeps the digestive system strong and functioning at its best, encouraging healthy gut flora and promoting regular bowel movements by bulking the stool. Besides supporting your digestive health, fiber-rich foods fill you up, aiding weight loss and weight management.
Plant foods, including whole grains, fruits, vegetables, beans, nuts, and seeds, are great fiber sources to include in a balanced diet. Nevertheless, many people don’t get enough fiber in their diet. So, taking fiber supplements can ensure you get your recommended daily fiber intake.
Keep reading as we bring you 7 of the best fiber supplements to try for weight loss.
Best Fiber Supplement for Weight Loss: 7 Top Options
With so many fiber supplements available, where do you begin?
Below, you can find our review of 7 fiber supplements to aid your weight loss journey and promote optimal health. We cover each product’s key features, pros, and cons to help you make an informed decision on the fiber supplement that will best match your needs.
#1 ColonBroom – best for suppressing appetite
- Promotes good gut health and a healthy digestive system
- Facilitates bowel movements
- May help to feel more satiated
ColonBroom is a dietary fiber supplement containing psyllium husk – a natural form of soluble fiber from the Plantago ovata plant. Psyllium husk is excellent for treating constipation, lowering bad cholesterol levels, and improving blood sugar control.
This powder supplement is marketed as an effective product for gut health as it fights bloating and constipation, cleanses the gut, and promotes regularity.
Although ColonBroom encourages bowel movements, it is not a laxative. It is also organic and free from sugar and artificial ingredients. As it’s non-addictive, you can safely incorporate ColonBroom into your diet.
Furthermore, if you practice intermittent fasting to shed excess pounds, ColonBroom will not break a fast. You can use it in the fasting window without hindering your progress. As the fiber content fills you up and suppresses cravings, it may stop hunger pangs when fasting.
- Acts as a gut and colon cleanser
- Promotes a bowel movement within 24–72 hours
- Helps regulate blood sugar levels
- Contains natural soluble fiber
- Zero sugar
- Vegan-friendly and gluten-free
- Fast-friendly
- Higher price point
- May cause bloating as your body adjusts to the extra fiber
#2 Benefiber – best with wheat dextrin
- Nourishes the good microflora in the digestive system
- Boosts daily fiber intake
- Supports gut health
- Good for the gut bacteria
- Promotes healthy digestion
Benefiber is a prebiotic supplement created to improve overall digestive health. The human body cannot digest prebiotic fiber. Instead, it travels through the body, nourishing and feeding the friendly gut bacteria to keep your digestive system healthy and happy.
Prebiotic supplements create a positive environment for weight loss. Although Benefiber is not exactly designed for weight loss purposes, it contains a soluble fiber called wheat dextrin. Studies show that wheat dextrin can decrease body weight and reduce cholesterol levels.
- Contains plant-based prebiotic fiber
- Dissolves easily in food and drinks
- No taste, which some people might prefer
- Sugar-free
- Wheat dextrin may cause bloating and gas in some people
- Requires 3 servings per day
- It meets the FDA requirements for gluten-free foods, but it is not entirely free from gluten and may not be suitable for people with celiac disease
#3 Metamucil – best for variety
- Promotes digestive health
- Supports heart health
- May lower cholesterol
- Boosts daily fiber needs
Metamucil is another fiber supplement designed to increase your daily fiber consumption to maintain gastrointestinal health. The makers of Metamucil claim that this product promotes appetite control and healthy blood sugar levels – two benefits that may help you lose weight.
Like ColonBroom, Metamucil contains psyllium husk, which is great for your digestive tract. It forms a gel-like mass that helps you feel full for longer. Unlike ColonBroom, however, Metamucil contains artificial sweeteners and flavors that are not ideal for your overall health.
- May lower cholesterol
- Supports appetite control
- Available in several forms, including fiber powder, fiber gummies, capsules
- Contains artificial ingredients
- May cause adverse effects, including bloating, diarrhea, and gas
- Psyllium is well-tolerated by most people, but it may cause an allergic reaction in some
#4 FiberCon – best with polycarbophil
- Great for constipation relief and maintaining normal bowel function
- Focuses on easier bowel movement with insoluble fiber
FiberCon is a bulk-forming fiber therapy, also known as a bulk-forming laxative, that provides occasional constipation relief. It is purposefully designed using insoluble fibers to get things moving again quickly. The active ingredient in FiberCon is calcium polycarbophil.
It adds bulk and moisture to stool for easier bowel evacuation. Insoluble fiber is not the best type for losing weight, as it primarily cleanses the colon and helps flush waste from the system. Bulk-forming laxatives may cause temporary weight loss results due to water loss.
- Promotes a bowel movement within 12–72 hours
- Reduces bloating and gas
- Suitable for a low-carb diet
- Convenient capulet form
- Requires multiple daily doses
- It should not be used for more than 7 days
- Doesn’t directly target weight loss
#5 Unbloat – best for bloating
- Promotes regularity
- Reducing bloating promotes a trimmer waistline
- Contains probiotics
As the name suggests, Unbloat is a prebiotic fiber supplement created to beat the discomfort of bloating. Digestive enzymes encourage digestion, helping you fully digest the food you consume. With greater digestion, you can expect healthier and more regular bathroom habits.
Bloating can make you slightly heavier, and reducing bloating may help you shed the odd pound. However, reducing your bloated belly will not lead to legitimate, long-term weight loss.
That doesn’t mean you shouldn’t try this fiber supplement. Removing the bloat will make you feel more comfortable in your body. It will mitigate discomfort so you can continue with your weight loss journey.
- Convenient pill form
- Can be taken long-term
- Claims to improve digestion within 6–8 weeks
- Vegan-friendly
- It fights bloating but will not aid in fat loss
#6 Bellway Fiber – best for regulating digestion
Bellway is a natural fiber supplement containing psyllium husk powder. It promotes a happy gut as it gently travels through the system, clearing out waste and toxins along the way. In doing so, it can reduce bloating and other digestive issues and can contribute to a balanced weight.
As psyllium absorbs fluid in the body, it can promote feeling full. In turn, taking this supplement may help you lose weight by reducing your overall caloric intake. When you eat fewer calories, you can create a healthy calorie deficit.
- Effective against constipation, diarrhea, and other digestive troubles
- Keeps your heart healthy
- May cause minor bloating in the beginning
- The fiber powder will not blend properly if the water is too cold
- Not suitable for people who have difficulty swallowing
#7 Sunfiber – best with galactomannan
- Good for occasional constipation and diarrhea
- It has a satiety effect that may promote weight loss
Sunfiber is a galactomannan-based soluble fiber known as partially hydrolyzed guar gum (PHGG).
This soluble fiber can help food move smoothly through your gut to mitigate constipation and diarrhea, promoting greater digestive balance. Meanwhile, it feeds the good bacteria in the gastrointestinal system to foster a healthy gut flora, an excellent benefit for overall wellness.
Unlike the fiber found in many other fiber supplements, Sunfiber encourages regularity without causing adverse side effects, such as excess gas and bloating. Furthermore, Sunfiber slows digestion and helps you feel full and satisfied for longer, which could aid in weight loss.
- No taste, so it doesn’t impact the flavor of food and drinks
- Gluten-free
- Won’t necessarily target your weight
How We Tested
We follow a decision-making process to bring you the best products to try. We rate products based on several factors, including overall quality, effectiveness, pricing, and brand reputation. Below, you can gain an understanding of what we look out for when giving recommendations for the best fiber supplements.
Quality
A high-quality supplement is important because you’re incorporating it into your daily diet. The best dietary supplements contain the ingredients necessary to deliver results with every serving while optimizing your overall health and wellness.
Those with natural ingredients and without sugar and artificial sweeteners are the healthier options. For example, ColonBroom contains psyllium husk – a natural source of fiber that offers various health benefits. It doesn’t have any harmful ingredients that reduce quality.
Effectiveness
There’s really no use in taking a fiber supplement if it doesn’t work.
Fiber supplements may work differently for everyone, but most fiber supplements should give you enough fiber per serving to help reach your daily recommendations. With the correct dose of fiber, a fiber supplement will encourage bowel movement, appetite control, and weight loss progress.
Price
Price is often the determining factor when choosing between fiber supplements. If the cost is too high, the product becomes unsustainable. It’s best to find a supplement that aligns with your expectations and your budget, so you can continue using it in the long term if needed.
Brand reputation
Rather than buying from an unknown company, it’s better to research a brand’s reputation. An insight into the brand can help you conclude if its mission matches your health goals. You can find relevant information through the company websites and reviews.

A Word From a Nutritionist
We all need dietary fiber to stay healthy.
There are two dietary fiber types – soluble and insoluble fiber. Soluble fiber dissolves in water and breaks down into a gel-like substance, promoting healthy digestion. Insoluble fiber draws water into the stool, adding bulk and making it easier to pass regular bowel movements.
Fiber consumption benefits many other aspects of human health. Fiber can help regulate blood sugar levels, reduce cholesterol levels, improve insulin sensitivity, and aid diabetes management. Adequate fiber intake can also aid weight management and help you lose weight.
Fiber can promote weight loss because it promotes satiety. It keeps you feeling full, which can help you refrain from binge eating and giving in to sugar cravings. If you are following the keto diet to lose weight, keto and fiber are essential to prevent keto diarrhea and constipation.
You should aim to eat lots of fiber sources from high-fiber foods, like barley, beans, lentils, nuts, seeds, and vegetables, but you can also take a fiber supplement. Fiber supplements are a great way to boost your fiber intake if you are not getting enough fiber from your diet alone.
The recommended daily fiber is 21–25 grams for women and 30–38 grams for men.
Dietary supplements should not replace fiber sources from the diet, but they can help balance things out. Keep in mind that the best fiber supplements for weight loss contain healthy ingredients and are free from added sugar and artificial sweeteners.
Conclusion
We’ve covered 7 fiber supplements to consider trying as part of your weight loss plan. These supplements provide a good amount of fiber to boost your health and help you reach your body goals. If you’re still trying to decide from our list, ColonBroom is our recommendation.
This sugar-free powder supplement targets gut health and might reduce cravings. It eliminates discomfort in the digestive system and increases energy levels.
A sudden increase in the amount of fiber you consume can cause digestive issues, such as bloating and gas. It’s better to start slow and gradually build up your intake to healthy levels.
