Information for participants and sponsors.

Each study has its own eligibility criteria. Start by completing the confidential online screening questionnaire on the relevant study page. If you appear suitable, a researcher will contact you to discuss the study and confirm eligibility. Completing screening does not commit you to taking part.

You will receive a Participant Information Sheet explaining the purpose of the research, what you would need to do, possible risks and benefits, privacy arrangements and who to contact. You can ask questions and take time to decide before providing informed consent.

Yes. Taking part is entirely your choice. You may decline to participate or withdraw later without penalty. Withdrawing will not affect your healthcare or your ability to enquire about other CRA studies.

Many CRA studies are randomised and placebo controlled. This means you may receive either the active study product or an inactive placebo, usually without you or the research team knowing which one during the trial. The information sheet for each study explains the allocation process.

Some studies provide gift vouchers or reimbursements in recognition of the time and travel involved. The amount and payment schedule differ between studies and are stated on the study page and in the Participant Information Sheet.

Personal and health information is handled according to the approved study protocol, privacy requirements and the Participant Information Sheet. Study results are generally reported in a way that does not identify individual participants.

Absolutely. You can contact the CRA research team before applying, while considering participation or at any time during a study. Current participants should use the contact details in their Participant Information Sheet.

Yes. CRA is based in Perth, Western Australia and collaborates with nutraceutical, botanical and natural-health companies worldwide. Projects can be planned and managed efficiently across time zones, with direct access to the researchers responsible for the study.

Our experience includes nutraceuticals, botanical extracts, probiotics, functional ingredients and selected lifestyle and natural-health interventions. We assess each opportunity for scientific merit, safety, regulatory practicality and recruitment feasibility.

You can contact us at the concept stage. A product summary and brief description of the evidence you hope to develop are enough for an initial conversation. We can help refine the research question, target population, outcomes, design and development pathway.

Timing depends on the study design, ethics review, target population, sample size, intervention period and recruitment complexity. Following an initial feasibility review, we provide a project-specific timeline covering preparation, recruitment, treatment, analysis and reporting.

Budgets vary according to sample size, study duration, visits, assessments, laboratory testing, recruitment requirements and reporting needs. CRA provides a transparent, itemised quotation after the scope and practical requirements have been clarified.

Yes. CRA can support the full study lifecycle—from feasibility, protocol development and statistical planning through ethics, recruitment, trial delivery, data management, analysis, clinical study reporting and peer-reviewed publication. We can also provide focused support for selected stages.

We design each study around a meaningful evidence objective, with appropriate participants, validated outcomes and prespecified analyses. Our team then interprets the findings clearly and helps identify practical next steps. Peer-reviewed publication depends on the study and journal process, but we can prepare the manuscript and support submission and peer review.
