What’s actually in it

first on the label · Hydrolyzed whey protein isolate, whey protein isolate, cocoa (alkali), natural & artificial flavor, lecithin, salt, sucralose, full list read.

artificial flavour'Artificial flavouring substances' on the label. Not dangerous at these doses, just a sign the food needs a costume.

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: 88 g/100 g · 23.6 g/100 kcal, may legally print “HIGH PROTEIN” via the per-100 g + per-100 kcal route.
