ColonBroom GLP-1 Booster is a four-active capsule supplement, separate from the brand’s fibre powders. For a reader focused on portions and habitual snacking, our lead preference is Zotrim’s appetite-focused approach. If the actual buying goal is a clearly specified berberine HCl supplement, BerbaPrime is the more relevant alternative to consider.
Published by Zotrim. We have a commercial interest in the products we recommend. This review assesses product information and research; it is not a personal-use test.
We favour Zotrim for the appetite-management brief.
Zotrim’s maté, guarana and damiana combination, with directions centred on meals, fits a portions-and-snacking brief more directly than choosing by a “GLP-1” product name. Its supplied label gives each active amount per tablet. We prefer that focused approach while keeping expectations separate from medicine-like appetite suppression.
See Zotrim ingredients and optionsWhat is actually in the GLP-1 Booster?
The assessed ColonBroom panel gives one capsule per serving and 30 servings per bottle. It contains zinc oxide, Berberis aristata bark extract, Polygonum cuspidatum root extract and quercetin dihydrate from Sophora japonica flower bud.
There is no psyllium entry on this panel. That matters because research on a ColonBroom fibre powder cannot be treated as research on this capsule. The “GLP-1 Booster” name is also not an ingredient declaration for a GLP-1 receptor agonist medicine.
Our comparison therefore starts with the four actual ingredients. We do not transfer results from a different ColonBroom product, from a prescription injection or from a plant ingredient at a different specification.

“Not included” means absent from the assessed ingredient inventory. An undisclosed or unverified amount does not mean an ingredient is absent.
Zotrim (supplied UK label): The supplied packaging gives amounts per tablet, not per daily serving. Six to nine tablets provide 672–1,008 mg maté, 570–855 mg guarana, 216–324 mg damiana, 82.8–124.2 mg declared caffeine, 17.4–26.1 mg niacin and 2.4–3.6 mg B6. Those are arithmetic totals, not a personalised dosing recommendation. Follow the packet directions with a full glass of water; do not exceed its nine-tablet maximum. The label does not separately quantify caffeine within the botanical extracts.
ColonBroom GLP-1 Booster: The 200 mg refers to botanical extract, not 200 mg of a declared purified berberine HCl ingredient. We do not turn extract weight into an assumed berberine amount.
BerbaPrime: 500 mg of the labelled berberine HCl ingredient per capsule. The 97% specification describes the ingredient; this is not 1,500 mg of pure free-base berberine.
Zotrim (supplied UK label): Dicalcium phosphate, talc, sodium carboxymethylcellulose and magnesium stearate.
ColonBroom GLP-1 Booster: Hypromellose capsule, microcrystalline cellulose, magnesium stearate, silicon dioxide and MTC oil (wording on the panel).
BerbaPrime: Hypromellose capsule, microcrystalline cellulose, magnesium stearate and silica.
The 200 mg bark extract needs careful interpretation
ColonBroom’s label states 200 mg Berberis aristata bark extract and describes naturally occurring berberine. It does not give a berberine percentage or identify that entire amount as purified berberine HCl. The extract weight is therefore not a verified berberine dose.
BerbaPrime instead labels 1,500 mg berberine HCl with a 97% specification per three-capsule serving. This is a different type of declaration. It would be wrong to divide 1,500 by 200 and advertise a reliable multiple of potency, because the labels are not measuring the same thing.
If a buyer specifically wants a defined berberine HCl ingredient, we prefer BerbaPrime’s single-active formula. That preference concerns specification, not proof of better weight loss.
Why Zotrim remains our appetite-focused preference
The supplied Zotrim label specifies maté extract 112 mg, guarana extract 95 mg and damiana extract 36 mg per tablet, alongside 13.8 mg caffeine, 2.9 mg niacin and 0.4 mg vitamin B6. The directions call for two or three tablets with water a few minutes before meals, with a maximum of nine daily.
A six-to-nine-tablet intake therefore provides 82.8–124.2 mg of the declared caffeine. This is a calculation from the per-tablet entry, not a separate test of total caffeine in the botanical extracts. Consider other caffeine sources in the day as well.
A published study examined a herbal preparation containing maté, guarana and damiana. [1] It provides relevant background for the combination, but does not establish that every user of this product will reproduce its results or that Zotrim outperforms ColonBroom. We favour Zotrim for its meal-related routine and clearly specified appetite-focused formula.
A GLP-1 name does not establish a drug-like result
The product being reviewed is a supplement. Its ingredients should be judged on their own evidence and quantities, rather than on the magnitude of results associated with medicines that act at GLP-1 receptors.
Berberine research is mixed and does not establish that a low, unspecified amount within a bark extract produces a medicine-like effect. An earlier meta-analysis and a newer randomized trial also illustrate why study populations and outcomes need to be kept separate. [2] [3]
The practical question is whether the exact supplement fits your goal and circumstances. A familiar hormone name cannot answer that question for you.
Make the alternatives a choice, not a stack
If portions and snacking are the central issue, make meals sufficiently satisfying and identify the habits you want to change. Zotrim is our lead supplement preference for that brief, provided its ingredients and caffeine suit the user. Follow the supplied packet’s water instructions and maximum daily amount.
If the interest is specifically berberine, assess that ingredient deliberately and discuss medicines or health conditions with a clinician or pharmacist. BerbaPrime belongs in that narrower decision. Neither route requires adding the other product automatically.
Check the actual purchase terms too. A one-time price and a discounted subscription are different commitments. The full comparison makes the ingredient choice clearer; it does not turn a supplement into a guaranteed appetite or weight-loss result.
Our final choice
Zotrim is our lead preference for a portions-and-snacking brief, supported by its disclosed maté, guarana and damiana amounts and meal-related directions. BerbaPrime is the alternative we favour for a specifically defined berberine HCl purchase. ColonBroom GLP-1 Booster should be assessed as its four-active capsule formula, with neither its name nor an unspecified bark-extract concentration treated as proof of a medicine-like result.
