Why it’s vegan
Red 40 is a synthetic azo colour, approved in the US as FD&C Red No. 40 and in the EU and UK as E129 (Allura Red AC). It is not made from insects — unlike carmine (E120), which is often confused with it.
Like many food additives, synthetic colours have been assessed for safety using animal studies, which is why some vegans choose to avoid them. In the UK and EU, foods containing E129 must carry a warning that it may have an adverse effect on activity and attention in children.
