Colon Broom Review: Overpriced Fiber or Health Breakthrough?

Colon Broom Review: Overpriced Fiber or Health Breakthrough?

| |
| |

Colon Broom is a fiber-based dietary supplement that claims to not only improve bowel regularity, but also to cause weight loss and reduce bloating. The company makes the bold claim that their product was formulated “thanks to modern breakthroughs in gastrointestinal science.”

But is Colon Broom actually superior to regular fiber or are these just marketing claims? Is the fiber dose effective for gut health? Are there questionable additive ingredients in Colon Broom? And how do real Colon Broom users rate and describe the effects of the supplement?

In this article we'll answer all of these questions and more, as we analyze the ingredients in Colon Broom based on clinical studies to give our take on whether or not this supplement is likely to support optimal gut health and cause weight loss.

We'll highlight some questionable health claims on the brand's website, feature unsponsored customer reviews, and provide a cost comparison to show which retailer sells Colon Broom for the best price.

We'll also compare the cost of fiber in Colon Broom to that in other popular fiber supplements to give our take on whether or not Colon Broom is overpriced.

Ingredient Analysis

Colon Broom active ingredient

Psyllium husk powder is the only active ingredient in Colon Broom, and is included at a dose of 3.6 grams (g).

Psyllium husk is a well-studied and effective type of fiber, but this is a relatively low dose. 

A clinical trial published in the International Journal of Molecular Sciences found that psyllium husk supplementation improved gut health, but the daily dose used was 21 g, or 5.83x the amount in Colon Broom.

A 2018 clinical trial found that psyllium husk supplementation improved bowel regularity, but the dose used was 10 g, or 2.78x the amount in Colon Broom.

We are unable to locate any medical studies suggesting that a fiber dose as low as that in Colon Broom has statistically significant effects on any health outcome, and Colon Broom does not appear to cite any on their website, so we will consider this supplement likely ineffective.

There is certainly no "breakthrough in gastrointestinal science" here: Colon Broom provides a relatively low dose of fiber with added flavoring ingredients.

The inactive ingredients in Colon Broom are shown below:

Colon Broom inactive ingredients

Citric acid is a preservative and flavor enhancer that can cause inflammation in some individuals, according to a series of case reports published in the Toxicology Reports journal.

Natural flavor is a broad descriptor that encompasses a wide range of flavoring agents.

As we documented in our Nu Biome reviews article, there exists medical research suggesting that some natural flavor compounds may be suboptimal for human health.

We do not currently recommend Colon Broom because of these inactive ingredients, and because of its price (which we'll discuss more in the next section of this article).

Is Colon Broom Overpriced?

As discussed in the previous section, Colon Broom is essentially psyllium husk fiber and flavoring ingredients.

Psyllium husk is widely available, so its price can be compared between Colon Broom and competitors.

Colon Broom contains 60 servings of 3.6 g of psyllium husk fiber, equating to a price-per-10-g-dose of $3.01 at the time of updating this article (for a one-time, single product purchase).

NOW Brands sells a psyllium husk powder that contains 76 servings of 7 g of psyllium husk fiber, equating to a price-per-10-g-dose of $0.25 on Amazon at the time of updating this article (for a one-time, single product purchase).

This means that per gram of fiber, NOW Foods' psyllium husk supplement costs 12x less than Colon Broom for the exact same active ingredient.

We consider Colon Broom to be overpriced.

Questionable Health Claims

Colon Broom questionable health claim example

Colon Broom’s website has a quiz that diagnoses health problems based on factors like weight and bowel regularity.

We completed the quiz with random answers and got a result showing a “45% chance of candida albicans growth,” as shown above.

This is unscientific and dangerous in our opinion. It's impossible to diagnose specific medical conditions based on bowel regularity quizzes, and we urge the company to stop engaging in this marketing practice without sharing any evidence that their process accurately diagnoses health conditions.

Colon Boom's website also states that the “unique complex of essential ingredients” in their formulation “works to improve your body’s detoxification processes...and eliminating accumulated toxins.”

We don't understand how Colon Broom can make this specific health claim if the supplement hasn't been tested in any clinical trials.

We recommend that consumers avoid supplement brands that make uncited health claims.

Does Colon Broom Cause Side Effects?

Colon Broom doesn't appear to have been studied in any clinical trials, which makes it more challenging to determine whether or not the supplement causes side effects.

However, we can make an educated guess based on its ingredients.

Increasing fiber intake can cause digestive side effects, whether that added fiber comes from a supplement or from high-fiber food like beans. These side effects can range from bloating, increased gas, stomach discomfort and irregular bowel movements.

We do not believe that Colon Broom is likely to cause any significant side effects, given that the fiber dose is relatively low.

The potential for side effects from increased fiber supplementation is why it's logical to slowly increase fiber intake to minimize digestive discomfort.

The brand's FAQ page also suggests that mild side effects are possible when first starting use of this supplement, due to the fiber.

Colon Broom vs. Metamucil 

Metamucil is one of the most popular fiber brands, so consumers are often curious about which product is better. 

Both Colon Broom and Metamucil contain the exact same type of fiber (psyllium husk) at a similar dosage, so the distinction comes down to added ingredients.

We consider Colon Broom to be a healthier choice than Metamucil, because Metamucil contains artificial flavors and artificial color.

Although we don't currently recommend either supplement, we would recommend Colon Broom to consumers intent on choosing between the two brands.

Metamucil is cheaper per-gram-fiber, so it may be a better option for consumers on a budget.

Customers Review Colon Broom

Amazon is a better resource for honest customer reviews than a brand's website in our opinion.

Colon Broom has been reviewed over 500 times on Amazon at the time of updating this article, with an average customer review rating of 3.8 out of 5 stars.

The top positive review from a verified purchaser comes from a user named "Stephanie" who gives the product a 5/5 star rating, and claims that it increased energy:

"i take medication and it states to take it at least 2 hours after (which i did as well). this gave me natural energy not like the crash and burn kind of energy from coffee. make sure to drink a lot of water with it or you will get dry mouth. it helped me have a lot more energy when working out and made me feel less bloated."

The top negative review from a verified purchaser is written by a user named "Mariah E." who gives the product a 1/5 star rating, and claims that it caused side effects:

"So I drank this for like 2 weeks and didn't have really anything dramatic happen. Then I drink it one day and I ended up having to leave work early because I threw up three times. Then when I finally got home had explosive diarrhea. So I stopped drinking it for 2 weeks. After 2 weeks I tried drinking it again, nope, within 2 hours of drinking this realized I had to leave work cuz I was going to throw up again and I didn't even make it home before I started throwing up in my car"

Colon Broom currently has an average review rating of 4.3 out of 5 stars on Google.

Where to Get the Best Price

Colon Broom is sold at a variety of online retailers. Here's a price breakdown at the time of updating this article:

Amazon: $69.99 (free shipping, doesn't require subscription, link to official Amazon listing)

Walmart: $64.99 (free shipping, third-party seller, link)

We do not currently recommend Colon Broom, and we disagree with some of the brand's health claims.

This is not a revolutionary, groundbreaking product. It's a fiber powder at a relatively low dose with added flavors and other inactive ingredients.

You can buy psyllium husk fiber for 12x cheaper per-gram from one of Colon Broom's competitors.

Colon Broom's website has a quiz that diagnoses health conditions, and we urge the brand to remove that section of their site because online quizzes cannot diagnose medical conditions, as we discussed at length in our hormonal imbalance quiz takedown article.

While Colon Broom may support gut function, we cannot identify any clinical studies suggesting that such a low fiber dose has specific health outcomes in humans. 

Colon Broom contains citric acid and natural flavors; both inactive ingredients that we recommend avoiding from a health perspective.

At the time of updating this article, the brand's website has the best price on subscription orders, while Amazon is the best retailer for one-time purchases (which the brand's website doesn't currently offer).
