Yes, most Huel Complete Protein flavors contain sucralose, a widely used non-nutritive sweetener. The Unflavored & Unsweetened version contains no sweeteners.

Sucralose is an artificial sweetener that is approximately 600 times sweeter than sugar. It is non-caloric, not stored in the body, and licensed for use in the USA, EU (E955), and over 80 countries worldwide. Only a small amount is absorbed — most is excreted without change. Sucralose has no effect on blood glucose, insulin response, or hunger signals, making Huel Complete Protein suitable for people with diabetes or those managing calorie intake.

Sucralose allows Huel Complete Protein to deliver a pleasant taste without added sugar, helping reduce the risk of tooth decay, weight gain, and cardiometabolic issues linked to excess sugar intake. Sucralose is approved by the FDA, EFSA, and other major health authorities.

Some early studies raised concerns about sucralose and gut microbiota, but most were animal-based studies using doses far beyond typical human consumption. More recent human trials show no consistent effects on gut function or the microbiome at realistic intake levels. Sucralose in Huel Complete Protein is consumed alongside prebiotic fiber, which supports a healthy gut environment.

If you prefer to avoid sucralose, Huel Complete Protein Unflavored & Unsweetened contains no sweeteners at all.
