We analysed every protein bar listed on Tesco.com in March 2026. Nutritional data comes directly from Tesco product pages. Ultra-processing markers, hidden sugar aliases, and dietary flags were computed by SpikeSaver's analysis engine.
All values are per 100g unless stated otherwise. “Hidden sugar aliases” counts the number of different names sugar appears under in the ingredients list. UPF markers identify ingredients characteristic of ultra-processed food under the NOVA classification.
SpikeSaver shows sugar analysis, NOVA scores, and hidden ingredient warnings — automatically on every Tesco product page.
No label reading. No guessing. Just better decisions.
