Your body can produce glutathione if you consume sufficient quantities of its precursors, especially cysteine, methionine, glutamate, and glycine
The search strategy was developed using keywords and Boolean operators such as rumen-protected methionine, methionine supplementation AND dairy cows, and methionine supplementation AND beef cattle. After retrieval, duplicate records, in vitro studies, literature reviews, and meta-analyses were removed

Published Phase 2 studies provide controlled evidence, but longer-range characterization, broader population diversity, independent replication, and final regulatory review remain incomplete
