What studies say about the key ingredients
Traditional use is not the same as clinical proof. Here is the strongest human research we found for each ingredient, limitations included.
- Mung beans
Breath hydrogen and methane were higher after wheat than after rice or mung bean noodles. Bloating scores after mung bean did not differ significantly from wheat, and mung bean produced gas levels similar to rice.Limitation: Small sample of 20 patients, with single meals tested rather than habitual intake, so longer-term effects of mung bean on symptoms are unknown.PubMed 31484315 · 1 more mung beans study - Tangerine peel
The tangerine peel drink group showed significant reductions in body weight and triglycerides after the intervention compared with the control group (p < 0.05). Safety markers showed no adverse effects. Gut microbiota and serum metabolite profiles also differed.Limitation: Small pilot trial with only 55 of 72 participants completing. The fermented product is not the same as plain tangerine peel, and the control group is not described.PubMed 40225325
