ColonBroom is a fiber supplement whose main ingredient is psyllium husk powder. It’s marketed primarily as a digestive health product that relieves bloating, supports regular bowel movements, and aids weight management. Sold as a flavored powder you mix with water, it competes in the crowded gut-health supplement space by positioning itself as a tastier alternative to plain psyllium fiber.
What’s Actually in It
The core active ingredient is psyllium husk, a plant-based fiber derived from the seeds of Plantago ovata. This is the same fiber found in well-known, much cheaper products like Metamucil. Everything else in the standard ColonBroom formula exists mainly to make it palatable: stevia leaf extract for sweetness, citric acid and crystallized lemon for flavor, fruit and vegetable juice for color, sea salt, rice hulls, and natural flavoring.
The company also sells a “Premium” version that adds several other ingredients, including cayenne fruit extract, chromium, B vitamins, iron, and an amino acid involved in fat metabolism. This version leans harder into weight-loss marketing.
How Psyllium Husk Works in Your Gut
Psyllium is a soluble fiber, meaning it absorbs water and forms a gel-like substance as it moves through your digestive tract. It’s classified as a bulk-forming laxative. Unlike stimulant laxatives that force your intestines to contract, psyllium works by pulling water into the small intestine and increasing the fluid content that reaches your colon. This softens stool, makes it easier to pass, and increases how often you go.
That extra water in the colon does more than just relieve constipation. Research published in the journal Nutrients found that higher stool water content was associated with increases in several beneficial gut bacteria, including species known to produce butyrate, a short-chain fatty acid that fuels the cells lining your colon. Faster transit times were also linked to shifts in microbial composition, suggesting that keeping things moving has downstream effects on gut health beyond just comfort.
Because psyllium expands in your stomach, it can also create a feeling of fullness. This is the basis for most fiber-related weight management claims: you feel less hungry, so you eat less. The fiber itself contains very few calories.
What the Company Claims vs. What’s Proven
ColonBroom’s marketing covers a wide range of benefits: reduced bloating, better energy, improved mood, weight loss, and enhanced focus. Some of these are well-supported by existing research on psyllium, while others stretch beyond what the ingredient alone can deliver.
Psyllium’s ability to relieve constipation and reduce bloating is well-established in clinical literature. These are the claims you can feel most confident about. The weight management angle is plausible but more nuanced. Fiber supplements can help with appetite control, but they don’t burn fat or boost metabolism on their own. Any weight loss from a fiber supplement is indirect, coming from eating less because you feel fuller.
The company registered a clinical trial on ClinicalTrials.gov to study ColonBroom Premium’s effects on body weight, waist circumference, gut health, metabolism, and energy levels over 12 weeks. Notably, the trial uses a single-group design with 120 participants and no placebo group. Many of the outcome measures rely on self-reported surveys rather than objective lab markers. This study design can show whether participants feel better, but it can’t prove the supplement caused those improvements. As of now, the trial’s results have not been published in a peer-reviewed journal.
Common Side Effects
Because psyllium is a fiber supplement, the most common side effects are digestive. Bloating, gas, nausea, stomach pain, and diarrhea can all occur, especially when you first start taking it or if you don’t drink enough water. These effects are usually temporary and tend to ease as your body adjusts over a week or two.
Starting with a smaller serving and gradually increasing can help minimize the initial discomfort. Drinking a full glass of water with each dose is essential. Psyllium absorbs a significant amount of liquid, and without enough water, it can actually worsen constipation or cause a blockage in rare cases. Allergic reactions, including skin rash, hives, itching, or swelling of the face and throat, are uncommon but possible and require immediate medical attention.
Pricing and the Subscription Model
ColonBroom is significantly more expensive than generic psyllium husk supplements. The product is sold primarily through a subscription model on its website, with discounted pricing for subscribers compared to one-time purchases. This pricing structure comes with a catch worth knowing about: if you cancel your subscription before the first recurring charge processes, you’ll be charged the difference between the subscription price you paid and the higher one-time purchase price. Once that first recurring payment goes through, you can cancel without any additional fees.
Generic psyllium husk powder, containing the same active ingredient, typically costs a fraction of ColonBroom’s price at any pharmacy or grocery store. What you’re paying extra for is flavoring, branding, and convenience.
Who It Might Help
If you struggle with constipation, irregular bowel movements, or bloating related to low fiber intake, a psyllium-based supplement can genuinely help. Most adults in the U.S. eat far less fiber than the recommended 25 to 38 grams per day, and adding a supplement is one way to close that gap.
ColonBroom is not a bad product. It contains a proven, well-studied ingredient. The real question is whether the flavoring and marketing justify the price premium over a basic psyllium powder that does the same thing. For some people, a product that tastes good and comes with clear daily instructions makes the difference between actually using it and letting a bag of plain fiber collect dust. For others, a $5 container of generic psyllium from the drugstore is the smarter choice.
