Our take
CleanPlate reviewWhey isolate with only lecithin and bromelain
The Whole Truth Whey Protein Isolate (Unflavoured) is a 1 kg tub with two ingredients: whey protein isolate (99.4%, instantised with lecithin) and bromelain (0.6%). One 35 g scoop gives 30 g of protein. The brand says it contains no flavours, sweeteners, gums or anti-caking agents.
CleanPlate scores it CC2. The C for nutrition is middling: 86.9 g protein per 100 g. The C for ingredients reflects mostly refined or industrial ingredients (led by whey protein isolate). The 2 for risk is low: sodium, free sugar and saturated fat are all modest (sodium 207 mg, free sugar 0 g, saturated fat 0.9 g per 100 g).

A closer look
Does the label add up?
Whey protein isolate (instantised with lecithin) 99.4% and bromelain 0.6%.
Per 100 g: 374 kcal, 1.9 g fat of which 0.9 g saturated, 1 g sugar of which 0 g added, 86.9 g protein, 207 mg sodium. Trans fat is printed as less than 0.01 g, so it is accepted as a declared zero. The listing's 88.9 g protein differs from the pack's 86.9 g, which matches the 30.4 g per serve and is used. The unflavoured powder has 1 g of total sugars per 100 g and 0 g added.
Ingredients to watch
- Lecithin and enzymeWorth watching
Lecithin (INS 322) and bromelain cost 1 point each in the additives score.
- Concentrated proteinWorth watching
A whey isolate is an industrial extract, which is why the ingredients grade is a C.
- SodiumFine
207 mg per 100 g, about 72 mg a scoop.
- SweetenersFine
None, and no flavour.
Common misconceptions
Myth: "Unflavoured whey is raw milk protein"
It is a filtered isolate with a dispersing agent added, not a whole food.
Myth: "Isolate has no lactose"
The brand states less than 0.5 g lactose per scoop, not zero.
