What’s in it
Amounts are shown only where the manufacturer publishes them. Anything without a figure is undisclosed — and for an active ingredient, an undisclosed dose is the central problem with this category.
- Plant-based prebiotic fibre6 g per serving
How the manufacturer says it works
Positioned by the manufacturer on the ingredient category described above rather than on weight loss outcomes.
What the evidence actually supports
The ingredient categories here — berberine, soluble fibre and probiotics — each have their own evidence base, covered in our ingredient guides. None acts on the GLP-1 receptor.
Where that evidence stops
No published human trial of this specific product. Ingredient-level evidence does not transfer automatically to a particular formulation or dose, and none of these products has weight loss outcome evidence.
