Our verdict
A dead heat — buy on flavour
Per bottle, these are functionally the same drink: 24.1g vs 25.0g protein, both exactly 185 kcal, both 100/A. One gram of protein and zero calories separate them — the rest is noise.
Underneath, small trade-offs: Barebells is denser per 100ml with less sugar (3.5g vs 5.1g); Müller brings the bigger bottle, less fat (0.5g vs 1.4g) and a better Clean Score (93 vs 88).
Verdict: there is no nutritional argument here. Buy the flavour you prefer — banana vs strawberry is the whole decision.
