Comparison

Metamucil vs ColonBroom: the same fiber at different prices

ColonBroom — often written Colon Broom — and Metamucil are both psyllium husk. ColonBroom’s label puts 3.6 g of psyllium in a scoop; Metamucil’s single-serve packet declares approximately 3.4 g. Both deliver 3 g of total fiber and 2 g of soluble fiber per serving. Once you know that, the useful comparison is cost, format and how each one is sold.

Where they differ

1. The fiber is the same, so the price difference is buying something else

3.6 g of psyllium against approximately 3.4 g. Both deliver 3 g of total fiber and 2 g of soluble fiber per serving. Every study either product can point to is a psyllium study. In the meta-analysis of 16 fiber trials in 1,251 people with chronic constipation, psyllium was the fiber with the clearest effect. The American College of Gastroenterology names psyllium the only fiber supplement with sufficient evidence to recommend. 28 trials in 1,924 people show LDL down 0.33 mmol/L. That evidence belongs to the ingredient rather than to either brand. What the price difference buys is flavor, sweetener choice, format and convenience — not a different or stronger fiber.

2. What each one costs per serving

ColonBroom’s plans page prices a bottle at $39.99 for 30 servings on the monthly plan — $1.33 a serving — falling to $0.67 a serving on the six-bottle plan. Its Walmart listing works out at about $1.00 a serving and the GNC listing at about $1.50. The label dose is two scoops a day after the first week, so $1.33 to $2.67 a day depending on which plan you are on. Metamucil at $0.22–0.25 a dose runs $0.66–0.75 a day at three doses. Plain unflavored psyllium husk powder runs $0.31 for a 7 g serving, which is twice the fiber of either.

3. How each one is sold

This is the practical difference for most people. Metamucil is a one-off retail purchase: you buy a tub, and if you do not get on with it you take it back to the shop. ColonBroom is sold direct, and its plans page presents recurring deliveries as the default option, with a one-time purchase also available at a higher per-serving price.

Its published terms are worth reading before you choose a plan, and we would say the same about any subscription. The cancellation policy states that if you cancel before the first recurring charge, “as you were offered the discounted price, you should pay the difference between the subscription and a one-time order.” The refund policy gives 14 days from delivery for products “proven to be not as described or faulty,” asks for photo evidence, and states that in the US and Canada “the shipping label costs $15… so this sum will be deducted from your refund.” It also states that refunds are issued for an initial purchase rather than for recurring subscription deliveries. Buying does not automatically create an account, so managing a plan means registering separately with the order email. None of that is unusual for a direct-to-consumer subscription; it is just materially different from buying a tub in a supermarket, and it is the thing to know in advance.

4. What each company claims

Metamucil carries an FDA-authorized health claim about soluble fiber and coronary heart disease, and its pack states the per-serving amount that claim depends on.

ColonBroom’s homepage cites figures of 83% losing weight within 10 weeks, 82% reducing food cravings in the first week and 90% seeing relief from bloating by week two. The company discloses the basis for these on the same page: “a self-reported survey conducted over 10 weeks with ColonBroom Premium,” adding that “no clinical trials have been conducted on other ColonBroom products at this time.” We are quoting that disclosure rather than characterizing it, so you can weigh a self-reported survey against a randomized trial yourself. For context on what psyllium’s randomized evidence covers: it is strongest for stool frequency, stool consistency and LDL cholesterol. Gel-forming fiber can blunt appetite, and Metamucil markets a two-teaspoon appetite-control dose on that basis, so fiber and appetite is a real connection — but weight loss is not where psyllium’s trial evidence is strongest.

5. The rating figures do not match across sources

Worth flagging because it affects how much weight to give any single number. ColonBroom’s own site cites 12,375 reviews without a star average alongside it. Trustpilot shows 4.0 out of 5 from 3,677 reviews. Its Walmart marketplace listing shows none yet, and the GNC listing for the Premium version shows four. We use the Trustpilot figure on this page because it is the largest independently hosted one we could verify, and we are flagging the discrepancy rather than picking the most flattering number. Metamucil’s 4.6 from 7,984 ratings comes from Walmart Business.

6. One label difference to be aware of

ColonBroom’s retail label carries a California Proposition 65 lead warning. For context, that is a California disclosure requirement rather than a finding that a product is harmful, and it appears on a great many supplements, foods and consumer goods sold in that state — particularly plant-derived ones, which take up trace minerals from soil. Metamucil’s label does not state one. If you would rather avoid Proposition 65 labeling altogether, it is a point of difference; it is not evidence that either product is unsafe.

What we would buy

ColonBroom is not sold through a retailer we link, so we have not linked it. If you want to look at it yourself, its Trustpilot page is here and prices are on the brand’s own site. Figures on this page were read from each company’s published label, pricing and policy pages and may change.
