Synopsis

Source of validity: Scientific
Rating (out of 5): 2

L-cysteine is a semi-essential amino acid known for its antioxidant properties, particularly due to its role as a precursor to glutathione, a major intracellular antioxidant. The scientific interest in L-cysteine for gastritis stems from these properties, as oxidative stress and free radical damage are implicated in gastric mucosal injury and inflammation associated with gastritis. Experimental studies, mostly in animal models, have investigated whether L-cysteine supplementation can help protect or heal the gastric mucosa by reducing oxidative damage. For example, some rodent studies have shown that L-cysteine or its derivatives (such as N-acetylcysteine) can decrease gastric lesions induced by ethanol or NSAIDs, likely through upregulation of antioxidant defenses and inhibition of inflammatory mediators. There are also a few small clinical studies suggesting that cysteine-containing compounds may have some protective effect on the gastric lining. However, robust, large-scale clinical trials in humans specifically evaluating L-cysteine for the treatment or prevention of gastritis are lacking. Most clinical evidence pertains to N-acetylcysteine rather than pure L-cysteine, and often in the context of related conditions such as H. pylori infection. Therefore, while there is a plausible scientific rationale and some preliminary supportive evidence, the overall level of direct scientific validation for using L-cysteine specifically in gastritis remains modest.
