Our services
We design and deliver nutritional intervention studies with the rigour of a regulated clinical trial — from dietary interventions and supplement efficacy to microbiome analysis and biomarker profiling.
We work with nutrition brands, food manufacturers, and academic institutions to design and run studies that generate credible, publishable evidence. From supplements and probiotics to complex dietary interventions, we apply robust clinical methodology to ensure your data is defensible.
Our remote-first approach enables large, geographically diverse participant cohorts — increasing the generalisability of your findings while keeping costs under control.
Study types
Supplement and probiotic RCTs, dietary intervention trials, microbiome studies, and bioavailability research
Outcome measures
FFQs, eDiaries, validated PROs, biomarker panels, and microbiome composition analysis
Compliance
GCP-aligned operations, ethics approval, and full GDPR compliance throughout
Delivery
End-to-end — from protocol and ethics through to final report and publication support
From study design to final report, we manage the full operational scope of your nutritional research study.
Study design, protocol and SAP drafting, ethics submission via IRAS or Ethiclear, and study registration where required.
Food frequency questionnaires (FFQs), multi-day eDiaries, 24-hour dietary recalls, and validated nutritional scoring tools — all captured remotely.
At-home blood, urine, or stool sample collection with laboratory analysis partners. Microbiome composition profiling and biomarker panel design included.
Statistical analysis to the pre-agreed SAP, final study report, and publication-ready outputs. We write results that are clear, credible, and defensible.
A typical nutritional intervention study with Comet Clinical follows four clear phases.
Protocol, design & ethics
We define the study design, select outcome measures, draft the protocol and analysis plan, and manage ethics submission — via IRAS or Ethiclear for non-CTIMP studies.
Setup & recruitment
EDC and eDiary built and validated, participant recruitment launched, remote screening completed, and eConsent obtained digitally before the study begins.
Intervention & data collection
Participants follow the dietary or supplement protocol at home, completing eDiaries, FFQs, and PROs at defined timepoints. Biomarker samples collected and dispatched to laboratory partners.
Analysis & reporting
Database lock, statistical analysis per the SAP, integration of biomarker and microbiome data, final report, and publication support if required.
