Dl-Methionine (CAS 59-51-8) is a high-purity essential amino acid serving as a critical nutritional building block for protein biosynthesis. Engineered for versatility, our pharmaceutical, food, and feed grades provide a potent solution for correcting amino acid imbalances in plant-based diets and promoting optimal metabolic regulation across diverse biological systems.
Widely recognized as a "skeleton" amino acid, Dl-Methionine is indispensable in livestock production, where it prevents stunted growth and muscle atrophy, and in medical applications for treating liver diseases and protein deficiency. With a purity level of up to 99%, it ensures maximum bioavailability and efficiency, offering a cost-effective alternative to L-methionine without compromising physiological efficacy.

Frequently Asked Questions
Physiologically, DL-Methionine produces the same effects as L-Methionine but is significantly more cost-effective. Because L-type is often derived from DL-type, DL-methionine is the standard choice for large-scale feed and industrial applications.
It acts as a nutritional enhancer that prevents stunted growth, weight loss, and muscle atrophy. It specifically supports liver and kidney function and improves fur/feather quality.
Yes, our Food Grade DL-Methionine is used as a nutritional supplement for amino acid fortification in health products. However, due to its specific odor, it is primarily utilized in specific products like fish cakes.
It is used as a primary component in amino acid infusions, composite amino acid preparations, and the synthesis of medicinal vitamins, as well as in liver-protective preparations due to its anti-fatty liver effects.
The general recommended addition amount in feed is between 0.05% and 0.2%, depending on the specific species and the existing protein levels in the base feed.
Many plant foods like corn, soy, and wheat are deficient in methionine. Adding DL-Methionine balances the amino acid profile, ensuring the body receives all essential building blocks for protein synthesis.
