Protein is everywhere, but the era of slapping a claim on pack and watching sales climb is over. Shifting consumer attitudes and GLP-1 medications are raising the stakes for brands.
Protein is no longer a trend – it’s a fixture. What began as a niche pursued by gym-goers has become mainstream, with protein claims now stamped across yoghurts, cereals, snack bars, even water. For years, growth felt effortless: put “high in protein” on a pack, and shoppers responded. That phase is ending. UK consumers have grown more sceptical of bold claims that aren’t backed by substance and more attuned to what they actually need.
So where does that leave an industry built on the simplicity of a single number? The answer lies less in formulation and more in how honestly brands communicate value.
