What’s actually in it

first on the label · Whey protein isolate, guar gum (INS 412), lecithin (322i), taurine/inositol, protease, full list read.

⚠thickener gumsGuar/xanthan/CMC/carrageenan, thickness that reads as 'richness'. Harmless for most, bloating for some.
✓digestive enzymesDigeZyme-style enzymes that help whey sit easier, useful if milk usually argues with you.

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.
FSSAI: 83 g/100 g · 22.3 g/100 kcal, may legally print “HIGH PROTEIN” via the per-100 g + per-100 kcal route.
