Swizzels Originals Love Hearts 125g are fizzy, fruit-flavoured sweets made with sugar, an acidity regulator (malic acid), and anti-caking agents (stearic acid, magnesium stearate, and magnesium carbonate). The recipe also includes sodium bicarbonate, modified starch, flavourings, and a variety of colours, such as anthocyanin, beetroot red, copper chlorophyllin, curcumin, lutein, and paprika extract. These sweets are suitable for vegans and do not contain common allergens like dairy, soy, or nuts as direct ingredients. However, Swizzels and retailers advise that because they are made in a factory handling products that do contain these common allergens, there is a risk of cross-contamination. Individuals with severe allergies should therefore check the packaging for any “may contain” warnings.
