Research notes
Research notes

Nutrition is from the Frosted Nutrition Facts image on the brand page ('about 5 servings per container', so 4 boxes = 20 servings; 14 g carbs include 9 g allulose). The brand page's marketing copy still says 110 kcal and 11 g protein, but the label image's ingredients (casein/whey concentrate, allulose, sunflower and avocado oil) match the current Amazon ingredient list, so the label was used. Price is Amazon's current one-time price (no deal badge, no Typical price shown); the brand site sells the same 4-box case for $39.00 and a single 7 oz box for $9.75.
