Why combine: A mix brings together gentle botanicals that complement each other. While individual herbs have evidence, a combined approach gives variety and supports a broader metabolic boost.

Ingredients to try: Use a small stick of cinnamon, 5 g soaked fenugreek, a few slices of cucumber, mint leaves, and a splash of lemon or lime.

How to make: Place all in a jug, top up with water, let steep in the fridge for a few hours or overnight. Drink through the day.
