How are Radicle Science studies different from other studies?
Our core focus is gathering clinical data to validate health and wellness products, the first of its kind! Our virtual, direct-to-consumer studies enable a smooth experience for participants, as well as enabling us to bring much needed equity and diversity into medical research. The unprecedented scale and reach of our studies finally enables inclusion of diverse ethnicities, genders, age groups, behavioral habits, and pre-existing health conditions to move us closer to personalized medicine for the population at large.
And unlike most studies, we share your results with you after the study in the form of a Personalized Participant Report, which not only summarizes your usage patterns over the course of the four-week study, but also compares your individual data to both the study population and relevant demographics and/or behavioral subsegments for actionable insights.
