Tell us about your project

Whether you need a full clinical trial, a protocol review, or a fractional research director, we've got you covered.

Dr. Cavanaugh responds personally to every inquiry within 2-3 business days. If your need is urgent, note that in the message and we will prioritize accordingly.

Why NRI

A named researcher. A published record. Methodological expertise that cannot be matched.


Harvard-trained PI with 25 years of nutraceutical and botanical clinical research. Dr. Cavanaugh personally leads every trial NRI runs. No handoffs to junior staff.


30+ peer-reviewed publications across stress, sleep, immune health, women's health, pediatric aromatherapy, and nutraceutical efficacy. Our methodology holds up in the literature.


Validated psychometrics built specifically, aka fit for purpose, for non-diseased populations and natural product claims. We don't try to fit supplements into pharmaceutical instruments.


95%+ average participant retention across trials. Near-perfect protocol compliance. Studies that produce clean data, not dropout-riddled datasets.

NRI designed the world's largest elderberry randomized controlled trial, n=362.  The data produced a 32% reduction in symptomatic days. This is what methodology-first research looks like.

What happens next

A straightforward process from first contact to signed agreement

You send an inquiry. Tell us about your product, your claims, and what you need. The more context, the more useful our response.

Dr. Cavanaugh responds within 2-3 days. Personally. With information relevant to your specific situation, not a generic auto-response.

We schedule a consultation. One call, usually 30 to 60 minutes. We ask about your product, your label claims, your timeline, and your budget. You ask about methodology, experience, and process.

We send a custom proposal. Scope, timeline, budget, and methodology approach specific to your study. Not a generic template. Usually within a week of the consultation.

You decide. If it fits, we move to agreement and onboarding. If it does not, we will tell you honestly and may be able to point you toward a better fit for your specific needs.
