The powders contain natural flavours, which make them more enjoyable to consume. They are only in the powders in very small percentages. We only use the highest quality natural flavours and ensure that they meet stringent food safety regulations and standards. All ingredients used in the manufacture of our natural flavours are approved for use in the FSANZ Food Standards Code 2002 (including all gazetted amendments). They are all made from natural ingredients, all of which are also classified as FEMA/GRAS according to US FDA regulations (this means that they are recognised as safe by the US FDA).
