Yes — most Huel Complete Protein flavours contain sucralose, a carefully chosen non-nutritive sweetener.
What is sucralose?
Sucralose is a premium sweetener that is approximately 600 times sweeter than sugar. It's non-caloric, non-addictive, and not stored in the body — meaning it doesn't impact blood glucose, insulin response, or hunger signals, making it ideal for diabetics and anyone managing calories.
Safety and approval: Sucralose is approved by the EFSA, FDA, and regulatory bodies in over 80 countries. It has robust safety data supporting its use in food and beverages.
Why we use sucralose: It allows us to deliver the dessert-like taste that makes Huel Complete Protein enjoyable — without added sugar and the associated risks of tooth decay, weight gain, and cardiometabolic issues.
What the science says about sucralose and gut health: Early animal studies raised questions about sucralose and gut microbiota, but many involved doses far beyond typical human consumption. Recent human trials show no consistent effects on gut function or microbiome at realistic consumption levels. Additionally, because Complete Protein contains prebiotic fibre, it may help balance any minor effects.
The result: Great taste without the sugar crash, perfect for protein-focused nutrition without compromise.
