Complete nutrition, put to the test.

Every Huel study begins with collaboration between our internal nutrition science team and independent researchers. Together, we define the study design, endpoints, and measures — whether it’s appetite hormones, micronutrient status, or consumer perception of wellness 

Each human study is reviewed and approved by institutional ethics committees before participant recruitment begins. Where appropriate, Trials are randomized, calorie- and protein-matched, and often crossover in design to ensure results are objective and comparable.

Our partners include academic institutions such as Newcastle University and independent research organisations such as Aelius Biotech. Huel provides products and funding but does not control data collection or analysis. Some studies using Huel products have been conducted entirely independently, with Huel having no involvement beyond product provision.

Once data collection ends, the research institutions analyze and interpret the results, which are then reviewed by independent statisticians. Huel’s nutrition team reviews the findings to better understand how our products perform and where we can innovate further.

Some trials have already been published in peer-reviewed journals, with others currently under review — a process that can take months to years depending on the study’s complexity and the journal’s timelines. Peer review is a cornerstone of rigorous scientific research, where independent experts assess and provide feedback on a study before it can be published.

Huel’s scientific program is ongoing. We continue to partner with external researchers on studies exploring appetite, metabolic health, nutrient adequacy, and long-term nutrition outcomes. Each new phase of research strengthens our mission to make complete nutrition not only accessible but proven.
