Our take

CleanPlate review

Whey blend with lecithin and nothing else

Optimum Nutrition Gold Standard 100% Whey Protein (Unflavored) is a 907 g tub of a protein blend of whey protein isolate and whey protein concentrate with lecithin as an emulsifier. One 29.5 g scoop gives about 24 g of protein. The panel is printed per 100 g.

CleanPlate scores it CC2. The C for nutrition is middling: 82 g protein per 100 g. The C for ingredients reflects mostly refined or industrial ingredients (led by whey protein isolate and whey protein concentrate), and almost no additives. The 2 for risk is low: sodium, free sugar and saturated fat are all modest (sodium 209 mg, free sugar 0 g, saturated fat 1.8 g per 100 g).

Per 100 g: 383 kcal, 3.4 g fat of which 1.8 g saturated, 2.8 g sugar of which 0 g added, 82 g protein, 209 mg sodium. The panel is per 100 g as printed. The isolate and concentrate shares are not declared and are estimated from the protein balance.

Ingredients to watch

  • EmulsifierWorth watching

    Lecithin (INS 322) costs 1 point in the additives score.

  • Concentrated proteinWorth watching

    Whey isolate and concentrate are industrial extracts, which is why the ingredients grade is a C.

  • SodiumFine

    209 mg per 100 g, about 62 mg a scoop.

  • Sweeteners and flavourFine

    None.

Common misconceptions

Myth: "Gold Standard means a pure isolate"

The first named protein is isolate, but the blend also holds concentrate.

Myth: "Unflavored whey has no additives"

Lecithin is listed as an emulsifier.
