Common questions about Klean Athlete Klean Isolate
How much of a Klean Athlete Klean Isolate scoop is actually protein?
20 g of protein from a 22.3 g serving — about 90%. The rest is flavoring, fats, carbs, and whatever else the label lists. A higher percentage means less filler per scoop.
Does Klean Athlete Klean Isolate disclose every dose?
Yes — the label lists an individual amount for each ingredient, with no proprietary blends. That is what the "label fully disclosed" tag on Scoop Sense means, and it is what lets each dose be compared against the amounts used in published research.
