DL-Methionine serves as a fundamental building block for biological protein synthesis and is an essential growth factor in livestock. It regulates animal metabolism and is widely used across the feed, pharmaceutical, food, and cosmetic industries.
In the feed industry, DL-Methionine is heavily used to enhance nutritional values. Incorporating just 1kg of DL-Methionine into feed yields a nutritional value equivalent to 50kg of fish powder. The standard recommendation is an addition rate of 0.2% to 0.5% in formulation.
In the medical field, it is a key component in aminophenol transfusions, compound amino acid preparations, and synthetic vitamin formulations. With its strong anti-fatty liver properties, it is commonly utilized in the manufacturing of liver protection medications.
In the food sector, it functions as a highly effective nutritional supplement and is extensively processed in various health foods and amino acid-enriched products.

DL-methionine is an essential amino acid that plays a critical role in protecting liver and kidney functions. It also helps promote healthy hair and nail growth, supports detoxification, and enhances muscle activity.
It is widely used to strengthen the nutritional profile of feed. The standard addition rate is between 0.2% and 0.5%. Adding 1kg of DL-Methionine provides nutritional value equivalent to about 50kg of fish powder.
According to our Certificate of Analysis, the specification standard requires a purity level greater than 99%, with actual test results confirming a high assay of 99.2%.
For smaller quantities of 1kg, we pack using double plastic bags inside an aluminum foil bag and an outer box. For larger orders of 10kg, 25kg, or more, the product is packaged inside drums or cartons containing 2-layer plastic bag inserts.
Small shipments (1kg–25kgs) are shipped door-to-door via express carriers like EMS, DHL, UPS, or FedEx within 3–7 days. Medium weights (25kg–100kgs) can go door-to-door or door-to-airport within 3–7 days. Shipments exceeding 100kgs can be sent by air (3–7 days) or by sea (10–35 days).
