Five-ingredient plant-based capsule formula now available through major U.S. retail channels alongside direct-to-consumer platform
BOISE, ID – September 3, 2026 – Gut Health UAB, the Lithuania-based company behind the ColonBroom dietary supplement brand, has listed ColonBroom GLP-1 Booster on Amazon and GNC, extending the product’s retail availability beyond its existing direct-to-consumer channel. The five-ingredient capsule formula, which entered the market as Gut Health UAB’s first metabolic wellness product, is now accessible through two of the largest dietary supplement retail platforms in the United States.
Gut Health UAB established the ColonBroom brand in the digestive wellness segment through a psyllium husk-based fiber supplement distributed primarily through direct-to-consumer channels. The addition of a metabolic supplement to the product line marks the company’s first entry outside its established gut health focus. According to company disclosures, the formulation process for the new product drew on peer-reviewed literature across each of its five active ingredients.
The formula contains Berberine, Chromium Picolinate, 5-Hydroxytryptophan (5-HTP), Saffron Extract, and Bupleurum Root Extract. It is manufactured as a 60-capsule bottle at a recommended dose of two capsules per day. The product carries no pharmaceutical GLP-1 receptor agonists or synthetic hormones. It is plant-based, vegan-certified, non-GMO, gluten-free, and stimulant-free. The “GLP-1” designation in the product name refers to the company’s stated interest in ingredients examined in published research for pathways associated with appetite and metabolic signaling — not to the inclusion of pharmaceutical GLP-1 compounds.
Berberine, a plant alkaloid found in goldenseal, Oregon grape, and barberry, is the formula’s primary active ingredient. A study published in Nutrition & Diabetes examined berberine administration in animal models and documented effects on intestinal cells associated with GLP-1 secretion pathways. A review in the Archives of Physiology and Biochemistry examined berberine’s relationship to glucose metabolism mechanisms including appetite-related signaling. UCLA Health has published educational materials noting that berberine’s published effects reflect modest metabolic associations and that its mechanisms differ from pharmaceutical interventions.

Chromium Picolinate provides a bioavailable form of chromium, an essential trace mineral. A study published in the Journal of Psychosomatic Research evaluated chromium picolinate supplementation at 600 to 1,000 micrograms daily over eight weeks, documenting differences in snacking frequency and carbohydrate craving behaviors between supplemented and placebo groups. The National Institutes of Health Office of Dietary Supplements notes that research on chromium’s metabolic effects has yielded mixed results across study populations.
5-Hydroxytryptophan (5-HTP) is an amino acid that the body uses to produce serotonin. A study in the American Journal of Clinical Nutrition examined 5-HTP supplementation at 900 milligrams daily over 12 weeks, finding differences in body weight and carbohydrate intake compared to placebo in a population without dietary restrictions. A separate double-blind crossover study at approximately 656 milligrams daily over five weeks documented differences in appetite and food intake between groups. Memorial Sloan Kettering Cancer Center has noted in published educational materials that further research is needed to establish consistent clinical outcomes. The company advises individuals taking serotonin-affecting medications to consult a healthcare provider prior to use.
Saffron Extract, sourced from Crocus sativus, has been examined in published research specifically in the context of snacking behavior and stress-related eating. A randomized, double-blind, placebo-controlled study published in Nutrition Research evaluated a patented saffron extract in 60 mildly overweight women over eight weeks. The study documented statistically significant differences in body weight, snacking frequency, and satiety scores in the saffron group relative to placebo. Researchers identified mood-related mechanisms as a likely contributing factor to the observed differences.
Bupleurum Root Extract, used historically in traditional Chinese medicine, contains saikosaponins — bioactive compounds studied in published literature for roles in liver function, inflammatory response, and stress modulation. Its inclusion connects the formula to ColonBroom’s established digestive wellness positioning. Gut Health UAB states that the formula is designed around a multi-pathway approach, with each ingredient targeting a distinct dimension of metabolic or appetite-related function. The company acknowledges that the specific ingredient combination has not been evaluated as a finished formula in clinical trials, and that individual ingredient research does not guarantee equivalent outcomes for the complete product.
“The decision to list on Amazon and GNC reflects our assessment of where consumers are currently purchasing dietary supplements and our commitment to making ingredient-transparent products available through those channels,” said Harold Ford, Head of Research, Gut Health UAB. “Each ingredient in this formula has a documented research record, and we have made that information available for consumers and healthcare providers to review independently.”
The supplement is manufactured and marketed in compliance with applicable U.S. dietary supplement regulations. Its statements have not been evaluated by the Food and Drug Administration, and the product is not intended to diagnose, treat, cure, or prevent any disease. Gut Health UAB recommends that individuals with pre-existing conditions — particularly those affecting blood sugar or serotonin metabolism — and women who are pregnant or nursing consult a qualified healthcare provider before use. The product is intended for adults only, and the company notes that individual results may vary.
The U.S. dietary supplement market has continued to expand across metabolic and weight management categories in recent years. Consumer purchasing data tracked by SPINS and published industry analyses have noted sustained demand for stimulant-free, plant-based metabolic support products distributed through both e-commerce and brick-and-mortar retail channels. The concurrent listing of ColonBroom GLP-1 Booster on Amazon and GNC positions the product at the intersection of these two primary distribution channels for the category.
“Retail distribution through established platforms creates accountability,” Ford added. “Consumers can compare products, read ingredient labels, and make decisions based on transparent information. That environment is consistent with how we approach product development.”
ColonBroom GLP-1 Booster is available through the official ColonBroom website, Amazon, and GNC. A satisfaction guarantee applies to qualifying purchases; terms and conditions are available on the official website. Customer and order support is provided through Gut Health UAB’s official contact channels. The company has disclosed plans to continue expanding its product line across gut health and metabolic wellness categories. Scientific references for each ingredient in the formula are accessible through the company’s website.
