Nutrition from the brand page's 栄養成分表示 for ミルクチョコ風味 per 28 g: 110.0 kcal, 20.6 g protein, 1.6 g fat, 3.3 g carbohydrate, 0.12 g salt equivalent (食塩相当量), plus 11 vitamins and Ca/Mg/Fe; protein content (anhydrous) 76.2% as stated by the brand. sodium_mg = 0.12 g salt x 393.4 = 47 mg (converted from the salt-equivalent value). Sugars are not on the Japanese label, so sugar_g is null. The page says whey protein is 100% of the protein source but does not give the full ingredient list or say concentrate vs isolate, so category is 'other' and sweeteners are null. Milk allergen inferred from whey. Not sold in the US; brand-page prices ¥7,344 incl. tax for 830 g, ¥3,348 for 350 g, ¥18,144 for 2.3 kg on 2026-10-14.
