ColonBroom is a fiber supplement built around psyllium husk powder, sweetened with stevia, and flavored to taste like a strawberry drink. Each scoop contains about 5.5 grams of powder and 20 calories. Beyond the psyllium, the formula includes a small number of supporting ingredients, but the fiber is doing most of the work.
The Main Ingredient: Psyllium Husk
Psyllium husk is the core of ColonBroom and the reason people buy it. It comes from the seeds of the Plantago ovata plant and is the same fiber found in Metamucil and other bulk-forming laxatives. What makes psyllium distinctive is its ability to absorb and hold water. When you mix it with liquid and drink it, the fiber forms a thick gel in your digestive tract. This gel retains water as it moves through your small intestine, increasing the fluid content that reaches your colon. The result is softer, bulkier stool that’s easier to pass.
Psyllium is not digested or absorbed by your body in any meaningful way. It passes through largely intact, which is why it adds bulk without adding significant calories. Clinical trials have also found that psyllium contributes to feeling fuller between meals. In one randomized, placebo-controlled study, a dose of about 6.8 grams taken before meals produced significant reductions in hunger and desire to eat compared to placebo, along with increased feelings of fullness. This is part of why ColonBroom markets itself for weight management, though the effect is modest.
Sweeteners, Flavor, and Color
ColonBroom’s strawberry flavor comes from natural flavoring, and its pink color comes from fruit and vegetable juice powder rather than artificial dyes. The sweetener is Rebaudioside A, a compound extracted from stevia leaves. It’s a zero-calorie sweetener that tends to be less bitter than other stevia extracts. There’s no sucralose, aspartame, or sugar in the formula.
Other Ingredients in the Formula
The supporting cast in ColonBroom is relatively short. The product contains citric acid (for tartness), silicon dioxide (an anti-caking agent that keeps the powder from clumping), and sea salt. Some versions of the product sold in different markets include additional medicinal ingredients. A version licensed through Health Canada, for instance, lists aloe ferox, magnesium, slippery elm bark, rhubarb root, and a blend of three fruits known collectively as triphala (Indian gooseberry, belleric myrobalan, and chebulic myrobalan). These are traditional digestive herbs included in small amounts.
The formulation can vary slightly depending on where and when you purchase. The core U.S. product sold on Amazon and through ColonBroom’s website centers on psyllium husk with stevia and natural flavoring. If you want to know exactly what’s in the version you’re buying, the supplement facts panel on the container is the most reliable reference.
Dietary Compatibility
ColonBroom is marketed as vegan, gluten-free, non-GMO, and keto-friendly. The low calorie count (20 per serving) and minimal carbohydrate content make it compatible with most restrictive diets. There are no dairy, soy, or egg ingredients listed. The product does not appear to carry third-party allergen certifications, so if you have a severe allergy, checking the label for shared-facility warnings is worth doing.
Common Side Effects
The most frequently reported side effects are bloating and gas, especially during the first few days of use. This is typical of any high-fiber supplement. Your gut microbiome needs time to adjust to a sudden increase in fiber intake, and the adjustment period usually involves some intestinal discomfort. Most people find these symptoms settle within a week or so.
Drinking enough water matters more with psyllium than with most supplements. Because the fiber absorbs so much liquid, taking it without adequate water can lead to the opposite of what you want: harder stools and worsened constipation. ColonBroom’s instructions call for mixing the powder into a full glass of water and then drinking an additional glass afterward. Skipping that second glass is a common mistake.
How It Compares to Plain Psyllium
A single bottle of ColonBroom with 60 servings costs about $70 at full price, or around $65 on a monthly subscription. For comparison, a generic container of psyllium husk powder with a similar number of servings typically runs between $10 and $20. The active ingredient is the same. What you’re paying for with ColonBroom is the flavoring, the stevia sweetener, and the branding. If you don’t mind mixing unflavored psyllium into water or a smoothie, you’ll get the same fiber at a fraction of the cost. If the taste of plain psyllium is a dealbreaker and the flavored version keeps you consistent, that consistency has value too.
The product is manufactured in NSF-certified facilities in the United States, which means the production process meets Good Manufacturing Practice standards for dietary supplements. This covers things like ingredient purity, contamination testing, and accurate labeling, though it does not mean the product’s health claims have been independently verified.
