What’s actually in it

first on the label · Whey protein isolate, nature-identical vanilla flavour, agar (INS 406), xanthan (INS 415), dipotassium phosphate, full list read.

⚠thickener gumsGuar/xanthan/CMC/carrageenan, thickness that reads as 'richness'. Harmless for most, bloating for some.

The fine print

Sucralose: Zero-calorie artificial sweetener. Regulators rate it safe at normal intake; a 2023 lab study flagged a trace impurity (sucralose-6-acetate) as genotoxic in cells. Doses there were far above what a scoop delivers.
Acesulfame-K: Zero-calorie artificial sweetener, usually paired with sucralose to round off the aftertaste.
FSSAI: 82 g/100 g · 21.9 g/100 kcal, may legally print “HIGH PROTEIN” via the per-100 g + per-100 kcal route.
