Nutrition from the Chocolate flavour declaration on BioTechUSA's official store page (per 25 g: 387 kJ/91 kcal, fat <0.5 g, sat 0.3 g, carbs 0.6 g, sugars <0.5 g, protein 21 g, salt 0.28 g; 36 servings per 908 g). Fat and sugar are declared only as '<0.5 g', so they are left null. The label gives salt rather than sodium, so sodium_mg is left null. Leucine is 2103 mg; BCAA (isoleucine 1142 + leucine 2103 + valine 1106 mg) is 4.4 g, both from the brand's per-serving amino acid table. Despite the 'Zero' name, the label claims 'lactose reduced' (0.20 g lactose per 25 g in Chocolate, 57-68% less than similar products depending on flavour), not lactose-free, so Lactose-Free is not listed. Every flavour also contains a creamer (partly hydrogenated coconut fat, skimmed milk powder, glucose syrup, sugar, milk protein). Chocolate ingredients: whey protein isolate (with soy lecithin) 85%, L-glutamine 5.5%, fat-reduced cocoa 5%, creamer, cellulose gum, xanthan gum, flavourings, salt, silicon dioxide, L-leucine 0.2%, sucralose, L-isoleucine 0.1%, L-valine 0.1%. Brand claims: sugar free (<0.5 g/100 ml prepared) and gluten free (<20 mg/kg). Made in a plant that handles egg, peanuts, nuts, celery, fish, crustaceans and sulphites. Some flavours (Banana, Vanilla, Pineapple-Mango, Pistachio, Strawberry) contain azo colours (tartrazine and/or Allura Red). Brand store prices are in a non-USD currency (908 g listed at 69.90), so no USD price was verified. No third-party certification is stated.
