@lenorj We know that adequate glutathione levels are important to lung health, but surprisingly little clinical research exists. Everything I was able to fine on an internet search was promoter-driven, with no research studies cited. When I switched to scholar.google.com, I found research evaluating the various components of glutathione, and their effects on human tissue, but no studies of its actual use and the results.

Can you explain who has recommended this? Have you spoken to your pulmonologist or primary provider about using it?
