Evidence supporting the use of: L-glutathione
For the health condition: Ulcers
Synopsis
Source of validity: Scientific
Rating (out of 5): 2
L-glutathione has some scientific basis for its potential use in supporting the treatment or prevention of ulcers, particularly gastric ulcers. Glutathione is a tripeptide composed of glutamine, cysteine, and glycine and is a major endogenous antioxidant in cells. Its main function is to protect tissues from oxidative stress, which is implicated in the pathogenesis of gastric mucosal injury and ulcer formation. Some animal studies have shown that depletion of glutathione in the gastric mucosa increases susceptibility to damage from non-steroidal anti-inflammatory drugs (NSAIDs), alcohol, and stress, while supplementation or preservation of glutathione levels may confer protective effects. For example, research has demonstrated that glutathione administration in rats reduces the severity of ethanol-induced gastric lesions by scavenging free radicals and supporting mucosal defense mechanisms.
However, direct clinical trials in humans using oral L-glutathione to treat or prevent peptic ulcers are extremely limited or lacking. Most human data focus on the general importance of antioxidants or on glutathione precursors (like N-acetylcysteine) rather than glutathione itself. Furthermore, oral bioavailability of L-glutathione is debated, as it may be broken down in the gut before reaching systemic circulation. While the theoretical rationale and animal evidence are promising, current scientific validation in humans is weak, placing the evidence at a 2 on the scale. Therefore, while some scientific rationale exists, L-glutathione is not a mainstream or well-established therapy for ulcers.
