Swizzels Originals Love Hearts 127g contain sugar, acidity regulator (malic acid), anti-caking agents (stearic acid, magnesium stearate, and magnesium carbonate), sodium bicarbonate, modified starch, flavourings, and colours (anthocyanin, beetroot red, copper chlorophyllin, curcumin, lutein, and paprika extract). These sweets are suitable for vegans and do not contain common allergens such as dairy, soy, or nuts as direct ingredients. However, Swizzels and various retailers explicitly state that the product is made in a factory that handles nuts and milk, which means there is a risk of cross-contamination. Therefore, individuals with severe allergies to these substances should exercise caution.
