A high-purity essential amino acid, DL-Methionine is widely recognized for its protein-building role, liver-supportive effects, and antioxidant functions, and is a key component in clinical nutrition, animal feed, and metabolic health formulations.
DL-Methionine is a synthetic form of the essential sulfur-containing amino acid methionine, composed of a racemic mixture of D- and L-isomers. As a key component in protein synthesis, methylation pathways, and glutathione production, it plays an indispensable role in supporting cellular detoxification, liver metabolism, immune system regulation, and tissue repair.
Methionine is not synthesized in the body and must be obtained externally through diet or supplementation, making DL-Methionine a critical input for nutritionally complete formulas—especially in animal feed, clinical nutrition, sports recovery, and metabolic health products.
Chibio Biotech’s DL-Methionine is a pharma-grade white crystalline powder, with a guaranteed assay of 99.6% (on dried basis), produced under GMP and ISO 9001:2015 certified standards. Our product conforms to European Pharmacopoeia (EP 8.8) and China’s GB 29938-2020 quality frameworks, ensuring maximum purity, batch consistency, and regulatory readiness for global markets.
