Smint Mint Sugar Free Mints (8g) contain sweeteners, primarily xylitol and aspartame, along with natural mint flavourings. Some versions also contain an anti-caking agent, such as mono- and diglycerides of fatty acids (from rapeseed) or magnesium salts of fatty acids, and fully hydrogenated cottonseed oil. The key allergens to note are that the mints contain aspartame, making them a source of phenylalanine. Additionally, excessive consumption of sugar-free products can have a laxative effect. While typically considered free from most common allergens like nuts and gluten, specific product variations can differ, so it is always best to check the individual package for the most accurate information.
