Yes. Most Huel Complete Protein flavors contain sucralose, a widely used non-nutritive sweetener.
What is sucralose?
Sucralose is an artificial sweetener that is:
• Around 600 times sweeter than sugar
• Non-caloric and not stored in the body
• Licensed for use in the EU (E955), USA, and over 80 countries worldwide
Only a small portion is absorbed, and most is excreted without change. It has no effect on blood glucose, insulin response, or hunger signals, making it suitable for diabetics and those managing calorie intake.
Why do we use it?
Sucralose allows us to deliver a pleasant taste without added sugar, helping reduce the risk of:
• Tooth decay
• Weight gain
• Cardiometabolic issues linked to excess sugar intake
Sucralose is supported by robust safety data and is approved by the EFSA, FDA, and other health authorities.
Gut health and sucralose: what does the science say?
Some early studies raised concerns about sucralose and gut microbiota, but:
• Many of these were animal-based and involved doses far beyond human use
• More recent human trials show no consistent effects on gut function or microbiome at realistic consumption levels
• Sucralose in Huel is consumed alongside prebiotic fiber, which may help balance any minor effects
Want a sucralose-free option?
If you’d prefer to avoid sucralose, try our Unflavored & Unsweetened version of Huel Complete Protein, which contains no sweeteners at all.
