Our Science

Our Groundbreaking Sleep Study

We are thrilled to announce the successful completion of our pioneering clinical trial for Defined Sleep. We are presenting the results from the clinical trial at Sleep 2023, a joint meeting of the American Academy of Sleep Medicine and the Sleep Research Society.

Defined Research has also made a manuscript describing the clinical trial freely and publicly available at medRxiv, a free online archive and distribution server for complete but unpublished manuscripts (preprints) in the medical, clinical, and related health sciences, while it awaits the results from peer review. 

In 2022 we completed the rigorous, double-blind, placebo-controlled trial of Defined Sleep’s patent-pending formula. This industry-first trial represents  a landmark step in understanding CBD’s effects on human Restorative Sleep. Visit ClinicalTrials.gov for in-depth information on our work.

Trial participants consisted of ~125 insomnia-suffering adults selected from across the United States. Objective and subjective sleep data was collected via wearable technology and participant surveys, respectively. Importantly, the clinical trial was approved by an Institutional Review Board (IRB), which ensured the human study was governed in accordance with FDA regulations and can be published in peer-reviewed scientific journals.

Why Purity Matters

At Defined Research, we’re committed to delivering the highest level of formula purity in all of our ingredients. We’ve spent years carefully selecting and testing everything that goes into our product, and we lab-test every batch before it’s bottled. The result is that Defined Sleep contains the same, precise concentrations of active ingredients – consistently resulting in a better night’s sleep.

This rigorous approach is different than most CBD sleep products which are composed of extracts from hemp plants. The problem, for consumers, is that the specific contents of every extract can dramatically vary from batch to batch – just like wines from the same vineyard taste different each year.

Sleep & Beyond

Creating a solution for insomnia is just the first step in our scientific exploration of CBD’s wellness capabilities. We’re committed to discovering CBD formulas that provide valid pharmaceutical alternatives for a wide range of chronic human conditions. In addition to insomnia, we believe CBD promises substantial therapeutic benefits for anxiety, pain, arousal, inflammation and more. These will be the focus of our journey as we continue to expand and perfect our science.

Test Results

Defined Research tests every lot to ensure safety and quality standards are met. We use CBD isolate that is 99.9% pure to ensure each batch is exactly the same and has 0.0% THC. Our CBD isolate is from a GMP certified manufacturer using Colorado grown hemp.

Our third party testing is done at an ISO/IEC 17025:2005 accredited laboratory and recognized by the United States Food and Drug Administration (FDA) lab. All of our products are tested for Potency, Terpenes, Pesticides, Heavy Metals, Residual Solvents, Foreign Materials and Bacteria.

Nothing is sold unless it passes.
