Nutrition read from the brand's 'Nutritional Information' image on the product page, labeled 'ISO-XP 1.8kg - Mango & Passionfruit' (per 25 g: 390 kJ / 93 kcal, fat 0.2 g, saturates <0.1 g, carbs 0.4 g, sugars 0.2 g, fibre 0 g, protein 22.4 g, salt 0.15 g; 72 servings per 1.8 kg). The image notes 'nutritional information may vary on other flavours'. Mango & Passionfruit still appears in the page's ingredient list but not among the current flavor options. The page headline states 22 g protein and 94 kcal. sodium_mg is calculated from the EU salt value (0.15 g / 2.5 = 60 mg). Ingredients (Vanilla): whey protein isolate (milk) 97% (contains emulsifier sunflower lecithin), natural flavouring, sweetener (sucralose); other flavors add cocoa or colours. 'Informed-Sport Tested' and 'Halal Certified Product' are stated on the brand page; neither was checked on the certifier sites. Gluten-free, non-GMO, vegetarian, soy-free and grass-fed (European) are brand claims. Made in a facility that handles milk, egg, soy, fish and gluten. Sold in GBP (450 g £28.95, 850 g £51.95, 1.8 kg £85.95); no US store was found (appliednutrition.com is an unrelated US company), so USD price is null.
