For the health condition: Free Radical Damage
Synopsis
Source of validity: Scientific
Rating (out of 5): 3
L-Glutathione is widely recognized in scientific literature as a key endogenous antioxidant, playing a central role in protecting cells from free radical damage. It is a tripeptide composed of glutamine, cysteine, and glycine, and is found in virtually every cell in the human body. Glutathione's primary function is to neutralize reactive oxygen species (ROS) and maintain redox balance within cells. Numerous in vitro and animal studies demonstrate that glutathione can directly scavenge free radicals and regenerate other antioxidants such as vitamins C and E, thereby enhancing overall cellular defense mechanisms (Reference).
Human studies examining glutathione supplementation for reducing free radical damage are more limited, and results are mixed. Some clinical trials have shown that oral or intravenous glutathione supplementation can increase tissue or blood glutathione levels and markers of antioxidant capacity, while others report minimal changes, possibly due to poor oral bioavailability (Reference). Despite this, the fundamental role of endogenous glutathione in neutralizing oxidative stress is well-established, and deficiency is associated with numerous disease states characterized by excessive free radical damage.
In summary, there is a scientific basis for using glutathione to support antioxidant defenses and mitigate free radical damage, but more robust clinical evidence is needed to confirm the efficacy of supplementation in healthy and diseased populations. The evidence rating is moderate (3/5) due to established mechanisms and promising preliminary data, but limited large-scale clinical trials.
