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

The EU and UK never approved BVO as a food additive. UK requires hyperactivity warning labels on products containing Yellow 5, effectively pushing brands to reformulate. EU and UK food regulations operate on a precautionary principle requiring safety establishment before approval.
