Nutrition for 2 lb Strawberry Cream from NIH DSLD 316514 (entered 2024-08-22, UPC 810007540887): 30 g, 30 servings, 110 kcal, 1.5 g fat, 2 g carbs, 2 g sugar, 90 mg sodium, 23 g protein; contains FD&C Red #40. Cookies & Cream (DSLD 316504) is 35 g, 140 kcal, 6 g carbs, 3 g sugar with 23 g protein. Leucine and BCAAs calculated from the labeled amino acids per 100 g protein (leucine 10.3, isoleucine 5.8, valine 6.0). 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. Grass-fed, Kosher and Halal are brand claims on si03.com. The 5 lb price on the brand store is shown only as an add-on amount, so only the 2 lb price ($41.09) is recorded. 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.
