Our take
CleanPlate reviewTwo-ingredient whey isolate with 90 g protein
Isopure Isolate Whey Protein Powder (Unflavored) is a 1 kg tub of whey protein isolate (100%) with an emulsifier (INS 322 i). One 28 g serve gives 25 g of protein. The pack says only two ingredients and no added colours, flavours or sweeteners.
CleanPlate scores it CC2. The C for nutrition is middling: 90 g protein per 100 g. The C for ingredients reflects mostly refined or industrial ingredients (led by whey protein isolate), and almost no additives. The 2 for risk is low: sodium, free sugar and saturated fat are all modest (sodium 178 mg, free sugar 0 g, saturated fat 0.3 g per 100 g).
