Brief Summary

The goal of this clinical trial is to test whether the gamma - glutamylcystiene (GGC) oral supplement can reach the brain and subsequently increase antioxidant glutathione (GSH) level in people with repetitive head impact (RHI). This will reduce the oxidative stress related injury in people with RHI.This unique study's main objective is to test the: 1. Change in GSH in brain and blood levels through GGC supplementation. 2. Change in the cognitive function in RHI patients due to GGC supplementation.
