2. What is L‑Methionine?

L‑Methionine is an essential sulfur-containing amino acid crucial for protein synthesis, methylation pathways, and the production of antioxidants such as glutathione. It cannot be synthesized by humans and must be obtained through diet or supplementation. L‑Methionine plays a critical role in nutraceutical, pharmaceutical, and functional food formulations.
