Nutrition (Dutch Chocolate, 28 g scoop, ~25 servings), ingredients, allergen statement and claims from the Vitacost listing reproducing the label (2026-10-13). Label lists total fat as '<1 g', so fat_g is null. Truly Grass Fed certified micellar casein from Ireland and 'independently certified by Labdoor' from legionathletics.com Casein+ page. Price is the Vitacost price; brand-site price not exposed. A 2.25 lb (1,020 g) size appears in a Harris Teeter search result but was not verified directly, so it is not listed in sizes.
