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
US Pepsi uses high-fructose corn syrup — a sweetener closely associated with metabolic disease risk at high consumption levels — while the UK version uses regular sugar. Both versions contain caramel color, but EU regulations place strict limits on 4-MEI content in caramel color, a compound California lists as a carcinogen. PepsiCo committed to reducing 4-MEI in US sodas in 2012 after California pressure but the UK/EU market has faced stricter limits from the outset.
