How We Tested

Testing supplements is important for determining their quality and overall effectiveness. Nobody wants to invest in something that doesn’t work. So, we examine each product’s essential features, strengths, and weaknesses before reaching a conclusion in our review.

Below, you can see the criteria we followed to reach a verdict.

Quality

We should never sacrifice quality when caring for our health. This is especially true when putting something into our bodies, like supplements. The best supplements are high-quality and contain natural ingredients in their formulas. It shows that the greatest care has been taken when perfecting the recipe.

Effectiveness

If it doesn’t work, why bother?

Supplements should do what they say on the packaging. We studied the ingredient lists to assess how well our chosen products work. Supplemental fiber should contain active ingredients that benefit the digestive system, like natural fibers and other nutrients for a happy gut.

For instance, ColonBroom is a popular fiber supplement because it contains psyllium husk, which is considered a superstar ingredient. This natural dietary fiber can provide relief for constipation, diarrhea, and other intestinal problems. It can also regulate blood glucose levels.

Price

Price is important because when you find the right fiber supplement, you will want to buy it regularly. Supplementing fiber in your diet shouldn’t cost the earth. While one might assume the most expensive product is the best, finding one that ticks the boxes for a reasonable price is better.

Brand reputation

A brand should genuinely care about the products they produce. Their ethos should clearly promote long-term health for customers with realistic results. Our selection of supplements comes from legitimate health companies that seem sincere in their mission to better health and treat digestive disorders.

A Word From a Nutritionist

Irritable bowel syndrome affects about 5% of the US population.

It is one of the most commonly diagnosed functional gastrointestinal disorders. It is a symptom-based disorder that primarily causes abdominal pain and irregular bowel habits. IBS patients may experience constipation, diarrhea, excessive gas, stomach bloating, and cramping.

Treatment includes stress management and a healthy diet that eliminates foods that trigger symptoms. A low FODMAP diet removes fermentable carbohydrates that the gut struggles to break down. Low FODMAP foods include proteins, wheat grains, fruits, vegetables, nuts, and seeds.

Physicians often recommend increasing fiber intake to keep your gut strong. Fiber is an indigestible carbohydrate that’s necessary for digestive function. You should eat a range of soluble and insoluble fiber sources.

Fiber-rich foods include oatmeal, wheat bran, wholemeal bread, bulgur wheat, brown rice, broccoli, and berries. Wheat bran supplementation is advocated as a primary treatment for people with IBS.

Those without enough soluble and insoluble fiber in their diets can benefit from fiber supplementation. Dietary fiber feeds the friendly bacteria in your gut, helping it flourish to keep your gastrointestinal system happy. A lack of fiber can irritate or worsen IBS symptoms.

You can benefit from taking a fiber supplement. Fiber supplementation is considered a safe and effective strategy to reduce IBS symptoms. In addition, dietary fiber has further health benefits. It can improve glycemic control, lower cholesterol levels.

A supplement is not a substitute for fiber sources in the diet. You should continue to eat a variety of fiber types and nutrients from whole foods. The supplement is simply there to boost your daily intake and ensure you get an adequate amount for proper digestive function.

Remember, fiber tolerance differs from person to person and too much fiber can have adverse effects on IBS.

Conclusion

Everyone is different and may have different needs for a fiber supplement. To help combat IBS symptoms like constipation and bloating, we think ColonBroom is the top choice. It contains essential psyllium fiber that improves the gut microbiota and cleanses your digestive system.

Other great options for those with IBS are Heather’s Tummy Fiber and Garden of Life Dr. Formulated Fiber.

Make sure you get medical advice from your doctor before supplementing fiber. They can guide you toward the right product for you based on your current health and ensure that the ingredients of your preferred product will not adversely affect your IBS condition.
