Low glutathione levels have been linked to abnormalities in the lungs' lining, and having normal glutathione levels may protect from inflammation by protecting lung tissue from free radical damage.27 Additionally, animal studies found that intravenous glutathione supplementation helped maintain normal lung function and prevent damage such as decreased lung compliance, increased swelling, and reduced lung tissue
Further human studies are required to substantiate the claims
In research studies, this route is evaluated for molecules that may interact with neural pathways or require rapid uptake
