Nutrition for 2 lb Chocolate Shake from NIH DSLD 316560 (entered 2024-09-25, UPC 810007541013): 32 g, 28 servings, 120 kcal, 2 g fat, 4 g carbs, 1 g sugar, 150 mg sodium, 23 g protein. Label states no taurine, glycine or maltodextrin. Leucine and BCAAs calculated from labeled amino acids per 100 g protein (leucine 10.5, isoleucine 5.7, valine 5.7). Glutamine peptides are a wheat-derived peptide ingredient (not free amino acids), so added_amino_acids is false; they are why the label declares wheat. Brand store showed "Not Available For Sale" for the default variant on 2026-10-14; the line is on-market (not marked off-market) in NIH DSLD.
