Taking fiber supplements can help people get the recommended daily fiber intake since many people don’t eat enough fiber in their diet.

8 Best Fiber Supplements for Weight Loss

With so many good fiber supplements available, where do you begin?

Let’s dive into an overview of 8 fiber supplements to aid your weight loss journey and promote optimal health. You’ll get to learn about each product’s key features, pros, and cons that will help you make an informed decision on the fiber supplement that could best match your needs.

#1 ColonBroom – Best overall

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 regular visits to the bathroom.

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.

#2 Garden of Life Dr. Formulated Organic Fiber – Best for hunger control

Garden of Life is another fiber supplement that is designed to support a healthy digestive system while also curbing appetite and promoting weight loss along the way. It contains a total of nine grams of fiber per serving, which is enough to maintain regular bowel movements and soften the stool.

The supplement is made from only plant-based ingredients, including five organic superfoods: acacia, oranges, baobab, apples, and cranberries. 

Acacia fiber, often called acacia gum, is a well-known soluble prebiotic fiber that promotes healthy waste elimination and acts as an appetite suppressant, giving a greater feeling of satiety and helping reduce calorie intake. It can also help with IBS (irritable bowel syndrome).

Garden of Life is completely organic and available in an unflavored or citrus-flavored form. It can be consumed by dissolving one tablespoon of the powder in water daily. This will be enough to feed the gut bacteria with high-quality prebiotics and ensure the growth of a healthy microbiome.

#3 Benefiber – Best for gut health

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.

Benefiber is often compared with Miralax, another popular laxative supplement that is primarily geared at alleviating constipation and promoting regular bowel movements rather than weight management.

#4 Metamucil – Best for appetite control

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. However, Metamucil also contains artificial sweeteners and flavors that are not ideal for your overall health.

#5 FiberCon – Best for improving bowel movements

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.

#6 Unbloat – Best for bloating

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. 

#7 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 serving size and overall caloric intake. When you eat fewer calories, you can create a healthy calorie deficit.

#8 Sunfiber – Best for mitigating diarrhea

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 ease 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.

How We Tested

In order to complete the list with the best fiber supplements on the market, we rated 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 for weight loss.

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.
