GLP-1 friendly, big bottle
This bottle qualifies outright (protein per calorie is identical at any fraction of a serving), but it is a lot to finish on a low appetite, so many people on these medications drink half now and refrigerate the rest. Our rankings show it as half a bottle.

Also Contains
Sweeteners
- Sucralose
Synthetic zero-calorie sweeteners such as sucralose, acesulfame potassium and aspartame. Regulators consider them safe at typical intakes, but the WHO advises against using non-sugar sweeteners for weight control, finding no long-term benefit, and in 2023 classified aspartame as possibly carcinogenic while leaving its acceptable daily intake unchanged.
WHO guideline on non-sugar sweeteners (2023)
Emulsifiers & Thickeners
- Cellulose Gel, Cellulose Gum
Cellulose-based thickeners: cellulose gum (carboxymethylcellulose) and cellulose gel (microcrystalline cellulose), often used together in shakes. A randomised controlled feeding trial of carboxymethylcellulose in healthy adults found it altered gut bacteria and reduced the protective mucus layer of the gut. The trial was small and short.
