ColonBroom Review: It's Psyllium Husk — at Three Times the Price

ColonBroom is one of the most heavily marketed gut products on social media, and if it's in your feed, the pitch — sweep yourself clean, lose weight, "detox" — is working on millions of people. Here's the entire review in one sentence: ColonBroom is flavored psyllium husk, the same active ingredient as Metamucil, sold at roughly three times the price per dose. The rest of this page is us showing that math, saying what psyllium genuinely does (a lot, actually), and letting you make an informed choice either way.

What's Actually in It

Per ColonBroom's own supplement facts label, one 5.7g serving contains 3.6g of psyllium husk powder — plus citric acid, natural flavor, stevia leaf extract, sea salt, fruit and vegetable juice for color, and rice hulls. That's the whole formula: psyllium and flavoring.

For comparison, a standard dose of sugar-free Metamucil is 5.8g of powder carrying approximately 3.4g of psyllium husk, per its FDA drug label. These are, for practical purposes, the same product: a flavored scoop of the same fiber at the same dose.

The Part That's True

We want to be fair here, because the ingredient itself is excellent. Psyllium is one of the best-evidenced over-the-counter treatments for chronic constipation — the updated systematic review of OTC therapies gives psyllium its strongest fiber recommendation, and the 2022 meta-analysis of fiber trials found meaningful improvement in stool frequency and consistency. It also carries an FDA-recognized cholesterol-lowering claim. Our Metamucil review covers the same evidence, because it's the same molecule.

So yes: if you started ColonBroom and things are moving, it's genuinely working. The question this page exists to answer is what you're paying for that result.

The Math

Both prices below are live Amazon prices we verified on September 1, 2026 — they'll drift, but not enough to change the conclusion:

• ColonBroom (strawberry, 50 servings, $39.99): about $0.80 per dose, each delivering 3.6g psyllium.
• Sugar-free Metamucil (orange, 114-dose canister, $26.99): about $0.24 per dose, each delivering ~3.4g psyllium.

Same active ingredient, same dose, roughly 3× the price — and plain store-brand psyllium husk runs cheaper still. Over a year of daily use, the ColonBroom premium is around $200. That buys a lot of strawberry flavoring and TikTok advertising.

The Part That Isn't True

Two claims in ColonBroom's marketing deserve a direct answer:

"Detox" and "cleanse." Fiber does not detoxify anything. Your liver and kidneys perform that function continuously; no toxin-removal benefit of psyllium has ever been demonstrated, and the "swept clean" feeling is simply what regular bowel movements feel like. It's a real benefit wearing a fake costume.

The implied product-specific science. As of this writing, a PubMed search for ColonBroom returns zero published studies. There is no trial of ColonBroom the product — every legitimate claim it makes is borrowed from research on generic psyllium, which is available from any product in our fiber rankings at a fraction of the cost.

If You Still Want It

Some readers will prefer ColonBroom anyway — the taste is genuinely more palatable to some people than Metamucil's texture, it's stevia-sweetened, and if a prettier canister is what gets you to take fiber every day, that consistency is worth something real. In that spirit: it's available on Amazon for about $40 (a paid link — we earn a commission, and we'd earn one on the cheaper products we actually recommend too, so our math above is against our own interest). Skip the subscription funnel on the brand's own site, take it with a full glass of water like any psyllium, and know that if it works, you can switch to the cheaper identical thing any time without losing a single gram of fiber.
