Why the difference?
The same company makes both versions — but they use different formulas depending on where the product is sold. In the EU, UK, and Canada, regulations require either banning certain additives outright or mandating warning labels (e.g., "may have an adverse effect on activity and attention in children" for certain synthetic dyes).
Rather than print warning labels, most manufacturers reformulate the product for international markets — using natural colorants like paprika extract, beetroot concentrate, or spirulina instead of petroleum-derived synthetic dyes.
The US FDA has a different standard: it deems additives "Generally Recognized as Safe" (GRAS) based on older safety data, while EFSA (the European Food Safety Authority) applies stricter precautionary principles and requires manufacturers to prove safety rather than assume it.

Key differences explained
Kellogg's voluntarily removed BHT from several US cereals after consumer petitions, yet BHT persists in Frosted Flakes varieties sold stateside. The UK version — branded Frosties — has never contained BHT, which is banned from cereals across the EU. The Texas Attorney General's 2025 investigation specifically named this double standard, noting Kellogg's reformulates for markets that demand it while maintaining cheaper formulations in the US.
