Metabolaid, a blend of lemon verbena and hibiscus extracts marketed by Monteloeder, was found to support weight management goals in a recent U.S.-based consumer evaluation.

A group of 112 adult participants were assigned to take the supplement at a 500 mg dose for eight weeks, and report their experiences. They also completed a self-assessment questionnaire at the end of each week to document their progress.

The participants reported that by the end of the study period, they experienced a weight reduction of around 3% by the end of the treatment, with a population-wide slow but sustained downward trajectory. By week four, participants began to report increases in motivation and energy, which endured throughout the rest of the evaluation. Participants also reported fewer urges to snack due to boredom, stress, or sadness, indicating greater control over emotional eating, the company reported.

More than 70% of participants felt that their eating habits had improved, characterized by greater control over snacking and increased preference for healthier options.

The weight loss was accompanied by a decrease in bloating, which was reported by a third of participants. Around two-thirds of users said they felt more energized, and after four weeks, reported they were exercising more, engaging in a sport or physical activity at least three times per week.

“A common complaint is that healthy eating routines are challenging to maintain,” said Mariana Ortega-Rufino, science marketing manager at Suannutra, parent company of Monteloeder. “Motivation often fades after the first weeks. Restrictive diets also backfire due to low energy, strong cravings, and increased stress, all of which make consistency difficult. This consumer study not only helped us better understand how people progress along their wellness journey but also highlighted how Metabolaid may inspire long-term adherence. Metabolaid seems to offer its users an emotional lift which keeps their motivation strong in addition to its physical effects.”

 Metabolaid has been tested in 10 preclinical and clinical studies, which included more than 450 volunteers, and each study was relevant to the ingredient’s ability to support weight control. Previous studies have demonstrated that it may influence pathways associated with metabolism, including adenosine monophosphate-activated protein kinase (AMPK), which is implicated in energy balance and satiety. It has also been shown to exhibit prebiotic properties. The polyphenol-rich botanical ingredient has also been linked to increases in GLP-1 levels, potentially supporting blood sugar and appetite reduction.

“Following a string of clinical trials that uncovered the science behind Metabolaid’s wellness benefits, we felt a consumer study would provide insights into the consumers’ perceptions of the product,” said Jonathan Jones, PhD, chief R&D officer for Monteloeder. “From their feedback we discovered Metabolaid’s potential to support individuals along their weight management journey by addressing both physical and emotional factors. It seems to be associated with fewer self-reported episodes of emotional eating, while powering users to make better lifestyle decisions, embrace healthier routines, and feel more positive about their daily eating patterns. These self-perceived shifts may contribute to behaviors that support long-term weight management efforts.”
