The present invention produces fermented kombucha beverages with reduced alcohol content by utilizing allulose or analogues thereof as the primary fermentable sugar. These rare sugars limit ethanol production during fermentation while preserving flavor, probiotic benefits, and acidity. The invention further encompasses the incorporation of Kratom (Mitragyna speciosa) extracts or alkaloids into the fermentation process or final product, enabling a low-alcohol kombucha with potential enhanced wellness properties. The resulting beverage maintains an alcohol content below 0.5% by volume, making it suitable for non-alcoholic labeling and broader consumer appeal. The invention is preferably a bottled beverage.

The present invention relates to a green coffee-based composition comprising hydrolysed chlorogenic acid for use in the treatment or prevention of a disorder linked to an increase in plasma postprandial insulin in a subject. The invention relates also to the non-therapeutic use of a composition comprising an esterase treated decaffeinated green coffee extract with an amount of 40-200 mg administered to a subject per day to decrease plasma postprandial insulin concentration. A further aspect of the invention is a process for forming green coffee based compositions.
