Product Description
DL-Methionine is a sulfur-containing essential amino acid ingredient widely used in animal nutrition, dietary supplementation, and specialized nutritional formulations. It is supplied as a high-purity amino acid powder or crystalline form for manufacturers developing feed additives, amino acid blends, and functional nutrition products.
Unlike L-Methionine, which contains only the biologically active L-isomer, DL-Methionine is a racemic mixture containing both D-Methionine and L-Methionine. Its stable quality, nutritional value, and cost-effective amino acid profile make it one of the most widely used methionine sources in global ingredient markets.
DL-Methionine is a synthetic sulfur-containing amino acid composed of equal proportions of D-Methionine and L-Methionine. Methionine is classified as an essential amino acid because animals and humans cannot synthesize sufficient amounts naturally and must obtain it from dietary sources.
Commercial DL-Methionine is commonly produced through chemical synthesis and supplied as white crystalline powder or granules. It is primarily used in animal feed formulations, amino acid nutrition products, and selected nutritional applications requiring a stable methionine source.

DL-Methionine is one of the most widely used amino acid feed additives. It is commonly incorporated into poultry, livestock, and aquaculture feed formulations to balance amino acid profiles and improve nutritional efficiency.
Feed manufacturers use DL-Methionine in formulated diets where methionine supplementation is required to achieve targeted amino acid composition. It is commonly used in poultry feed due to its established nutritional application.
DL-Methionine may also be used in specialized nutritional products where a methionine source is required. Product selection depends on formulation objectives, regulatory requirements, and target application.
For ingredient buyers, DL-Methionine selection mainly depends on purity, physical form, application category, and quality documentation. Feed manufacturers typically evaluate amino acid content, processing performance, and supply consistency when selecting a methionine source.
| Selection Factor | Why It Matters | Typical Buyer Consideration |
|---|---|---|
| Purity Level | Determines amino acid contribution and formulation accuracy | High-assay grades are commonly selected for feed applications |
| Physical Form | Affects mixing, handling, and production efficiency | Powder or granule forms may be selected according to feed processing needs |
| Application Type | Influences specification and documentation requirements | Select according to poultry, livestock, aquaculture, or nutritional applications |
| Quality Documentation | Supports supplier approval and batch verification | COA, TDS, SDS, and analytical reports are commonly requested |
DL-Methionine is commonly supplied in 25kg bags, fiber drums, or bulk packaging formats suitable for industrial handling. Packaging options can be adjusted according to transportation, storage, and production requirements.
DL-Methionine supports customized nutritional ingredient projects. OEM services may include ingredient blending, customized packaging, labeling solutions, formulation support, and technical documentation preparation.
Typical quality control procedures for DL-Methionine include:
DL-Methionine is primarily used as an amino acid feed ingredient in poultry, livestock, and aquaculture nutrition. It is also used in selected nutritional formulations requiring a methionine source.
DL-Methionine contains both D-Methionine and L-Methionine isomers, while L-Methionine contains only the naturally occurring L-form. Both are used as methionine sources depending on application requirements.
DL-Methionine quality is commonly evaluated through assay testing, amino acid analysis, identity confirmation, moisture testing, and other applicable quality control procedures.
DL-Methionine is a widely used sulfur-containing amino acid ingredient for animal nutrition, feed additives, and specialized nutritional applications. With standardized specifications, reliable quality control, and flexible packaging options, it supports professional formulation development and bulk ingredient procurement.
