Swizzels Mega Double Lollies contain dextrose, cornflour, modified starch, and an acidity regulator (malic acid). To achieve their distinctive colour, they use anthocyanin, copper chlorophyllin, curcumin, lutein, and paprika. The lollies are known to be free from artificial colours and are suitable for vegetarians and vegans. As with most sweets from this manufacturer, there are no common allergens such as milk, soy, or nuts listed as ingredients. However, as Swizzels facilities produce a wide range of products, there is always a risk of cross-contamination with common allergens, so individuals with severe allergies should still exercise caution.
