The Halls Mentholyptus Sugar Free Original lozenges (32 g) are formulated with sweeteners—namely isomalt, aspartame, and acesulfame K—alongside flavourings, acidity regulators (sodium lactate, potassium citrates), and acids such as lactic acid and citric acid. According to packaging standards, allergens are emphasized in bold; this product contains a source of phenylalanine, which is particularly important for those with phenylketonuria (PKU). Additionally, excessive consumption may produce laxative effects, a common advisory for lozenges formulated with polyol sweeteners
