Nutrition from the US brand page's nutrition table, labeled as the Unflavored version (1 scoop 29 g: 110 kcal, 0 g fat, 40 mg sodium, 1 g carbs, 0 g sugar, 25 g protein) (2026-10-13). Page inconsistencies: Suggested Use says '1 large scoop (25g)', copy claims '90% protein' (panel works out to 86%) and 'no added sugar' although Strawberry Milkshake ingredients include sugar. Strawberry Milkshake ingredients: whey protein isolate (whey protein, sunflower lecithin), natural & artificial flavor, stevia leaf extract, cellulose gum, salt, vegetable juice (color), sucralose, acesulfame potassium, sugar; contains milk. Sweeteners listed are those in flavored versions; Unflavored has none. Page also shows a second ingredient list for some flavors beginning with whey protein concentrate, which may be a site error. No BCAA/leucine amounts given. Informed Choice listing for Impact Whey Isolate (USA) (certified 2024-05-30) and Informed Protein listing confirmed via certifier-site search results; brand page claims both. Only the 0.55 lb size/price ($23.99 sale, $29.99 list) was visible.
