Premier Protein
Score
- Contains non-nutritive sweeteners
- Contains emulsifiers studied for gut effects
Why it scores 81
Premier Protein scores 81 out of 100 (Excellent) under GoodSwap’s published rules. What moved the score most:
- minus 5 points Cellulose gum (carboxymethylcellulose): In a small randomized feeding trial, carboxymethylcellulose modestly increased abdominal discomfort and reduced gut microbiota diversity; in mice it promoted low-grade inflammation. Strong
- minus 5 points Sucralose: In a 2022 randomized study, sucralose and saccharin altered the gut microbiome and impaired glucose responses in some people; a 2023 lab study raised questions about its by-product sucralose-6-acetate. Strong
- minus 5 points Acesulfame potassium (Ace-K): In the NutriNet-Santé cohort, acesulfame-K intake was associated with higher cancer risk; cause and effect is not established. Strong
Every line of the math is on The Receipt below, with its evidence tier and sources.
