Key Differences

L Glutamine is an essential amino acid that plays pivotal roles in the body, including protein synthesis, cell volume regulation, and nitrogen transport. On the other hand, Glutathione, often referred to as the body's "master antioxidant," primarily defends cells from oxidative damage by neutralizing harmful free radicals.
