Naturally Produced Cannabinoids for Neuroprotection From Concussion

The goal of this double-blind, placebo-controlled, cross over study is to learn about the neuroprotective properties of a broad-spectrum cannabinoid formulation in normal healthy adults engaged in elite contact sport competition. The main question it aims to answer : • Is the broad-spectrum cannabinoid formulation neuroprotective for athletes participating in competitive contact sports? Can this formulation facilitate recovery in those who suffer from concussion by reducing inflammation and/or reduce the number of concussions sustained without adverse physiological and psychological dysfunction when administered daily? Participants will: * be given a broad-spectrum cannabinoid gel capsule or a placebo twice daily. * have blood samples taken to analyze pharmacokinetics and pharmacodynamics of cannabinoid metabolites, liver function, complete blood count and blood differential, inflammatory biomarkers and genetic analysis * have stool samples collected for gut microbiome analysis; * undergo testing sessions, which will include psychological and health questionnaires, equipment to record signals from the brain and heart, and safety laboratory tests.
