Read the detailed description
This is a randomized, double-blind, placebo-controlled study conducted with adult participants, residing in the United States. Eligible participants will (1) have the opportunity for meaningful improvement (at least 30%) in their primary health outcome, and (2) express acceptance in taking a product and not knowing its formulation until the end of the study. Participants that report a known cardiac dysfunction, liver or kidney disease may be excluded. Participants that report a known contraindication or with well-established, significant safety concerns due to illness will be excluded. Heavy drinkers and those who report they are pregnant, trying to become pregnant, or breastfeeding will be excluded. Participants that report taking medications with a known contraindication or with well-established, significant safety concerns will be excluded.
Self-reported data are collected electronically from eligible participants for 12 weeks. Participant reports of health indicators will be collected at enrollment and throughout the active period of study product usage. All study assessments will be electronic; there are no in-person visits or assessments for this real-world evidence study.

What is being measured
The primary outcome is the main question the study is designed to answer.
Change in cognitive function
Change in cognitive function: Difference in rates of change over time in cognitive function score as assessed by PROMIS Cognitive Function 8A (scale 8-40; where lower scores correspond to worse cognitive function)
Measured: 13 weeks
Secondary outcomes (3)
Change in fatigue
Change in fatigue: Difference in rates of change over time in fatigue score as assessed by Patient Reported Outcome Measurement System (PROMIS) Fatigue 8A (scale 8-40; where higher scores correspond to more severe fatigue)
Measured: 13 weeks
Change in sleep-related impairment
Change in sleep-related impairment: Difference between rates of change over time in sleep score as assessed by PROMIS Sleep-Related Impairment 8a (scale 8-40; where the higher scores correspond to worse sleep)
Measured: 13 weeks
Change in cognitive abilities
Change in cognitive abilities: Difference between rates of change over time in Cognitive Abilities score as assessed by PROMIS Cognitive Function - Abilities 8a (scale 8-40; where the higher scores correspond to better cognitive abilities)
Measured: 13 weeks

Questions about this trial
What is this clinical trial studying?
A study testing RS Clarity Active Product in people with Cognitive Function, run by Radicle Science at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 6 inclusion and 15 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: under way, not looking for participants, as of the sponsor's last update on 20 Aug 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
