The Active Ingredient Is: Gymnema Sylvestre Extract

Gymnema sylvestre extract is a plant-derived nutrient used to help with ordinary cellular processes involved in carbohydrate handling day-to-day.

This form is standardised for active constituents and is used as the primary ingredient in this formulation to help with everyday glucose metabolism and nutrient partitioning.

What Does Gymnema Sylvestre Extract Do?

Gymnema sylvestre extract helps manage glycaemic parameters by supporting normal glucose uptake and utilisation, as noted in Diabetes Care literature. These effects are discussed in the context of everyday carbohydrate metabolism and energy balance.

EFSA guidance acknowledges the role of nutrients in supporting normal metabolic function, while NHS guidance emphasises maintainable glucose balance as part of daily wellness.
