See how Reducose® works

Reducose® is a patented water extract from white mulberry leaves designed to support healthy blood sugar levels after meals. With a scientifically proven mechanism of action, it works by partially inhibiting the alpha-glucosidase enzyme responsible for breaking down refined carbohydrates.
