Reviewed November 3, 2026. Reputable Health, Citruslabs and Radicle Science offer research for consumer health products. Their services overlap, so the useful comparison is the study each proposes for your specific question.
The short answer
Reputable Health
Reputable designs and runs decentralized clinical studies for health and wellness brands and ingredient manufacturers. Depending on the protocol, studies can combine wearable measurements, participant questionnaires, laboratory measurements and other assessments. The agreed scope defines responsibilities and deliverables. Source: Reputable’s clinical research program.
Citruslabs
Citruslabs describes consumer perception studies, single-arm clinical studies and randomized controlled trials for consumer health brands. Its published services include protocol development, recruitment, data analysis and reporting, with laboratory measurement options. Source: Citruslabs.
Radicle Science
Radicle Science describes research for supplements, foods, beverages and pet products. Its published trial options include randomized controlled trials, open-label studies and in-home use tests, with survey, biomarker, wearable and digital measurement options. Source: Radicle Science.

How to decide which partner fits
Send the same research brief to each provider. Specify your product or ingredient, intended participants, outcome, assessment period and the decision you need the study to inform.
- Ask why the proposed design fits the question and what comparison is needed.
- Confirm which measurements are appropriate for the population and intended use.
- Ask how the team will handle unusable recordings, missing data and withdrawals.
- Separate included services from optional recruitment, laboratory work, communications or publication support.
- Request the reporting and data-access terms in writing.
- Compare proposals on responsibilities and evidence needs, not just a starting price or participant count.
For manufacturers, our ingredient clinical study buyer’s guide provides a more detailed planning checklist. Citruslabs also publishes pricing information; confirm how the quoted design, services and schedule apply to your project.
Inspect the evidence and its limitations
Reputable’s published phytomelatonin sleep pilot summary links to the PubMed publication. It is an exploratory open-label pilot with baseline comparisons. It should not be presented as a placebo-controlled efficacy trial or proof that another product will produce the same findings.
Read our research methodology and evidence standards and platform overview to understand our approach. For other providers, request published examples and documentation relevant to the study being proposed.
Match claims to the evidence
Remote collection, a wearable device or a large participant count does not by itself determine what a study can establish. Interpretation depends on the design, measurements, execution and analysis. Ask the research team to explain both the conclusions the study could support and what would remain uncertain. Our structure/function claims evidence guide discusses the U.S. supplement context.
Questions to ask before choosing
Does one provider have the best design for every product?
No. Start with the research question and compare justified proposals. Provider descriptions and general rankings cannot replace a protocol-specific assessment.
Are wearable measurements unique to Reputable?
No. Radicle Science also publicly describes wearable measurement options. Ask each provider which devices, outcomes and collection methods fit your study rather than assuming exclusivity.
Is publication included?
Reputable’s manuscript and journal-submission support is separately scoped, and acceptance and publication are not guaranteed. Ask every provider to specify what publication support, if any, is included.
