Brief Summary

Cannabidiol (CBD), a non-psychoactive hemp derivative, is an attractive therapeutic target, and is most supported by the scientific community as an antiepileptic, anxiolytic, and antipsychotic. Additionally, CBD may cause alterations in aspects of health and fitness, fatigue, stress, calmness, quality of life, cognitive function, ability to maintain focus, sleep quantity, and sleep quality. Cannabidiol may be associated with alterations in inflammatory response in the human body, which has implications in both healthy and diseased populations. Natural killers cells (NKC) play a vital role in maintain your body's defenses and are an essential component of your immune system. In humans, NKC contain the highest concentrations of receptors associated with the endocannabinoid system and CBD. Human models have demonstrated that CBD use increases the percentage of NKC in peripheral blood. However, similar models found that CBD administration inhibits markers of NKC cytotoxic function, a beneficial cellular mechanism used to prevent malignant cell transformation and viral infection. The overarching goal of this investigation is to determine the effects of an 8-week CBD intervention on measures of fatigue, stress, calmness, quality of life, cognitive function, focus, health and fitness, and sleep quantity, and sleep quality. In addition, this study will explore a potential CBD mechanism of action with a focus on biomarkers of neural health, inflammation, liver health, kidney health, as well as NKC number and function.
