Sources
Nutrition from Bulk UK official product page nutrition table (per 30 g serving); page does not state which flavour the table refers to (ingredient list includes cocoa). Label lists salt 0.19 g per serving rather than sodium, so sodium_mg left null. Headline claims 'up to 26 g' protein but table shows 24 g. No third-party certification stated on page. May contain soya, gluten, mustard, sesame, sulphites (cross-contact). USD price not verified.
