DL-Methionine Hydroxy Analogue - Feed Ingredient

DL-Methionine hydroxy analogue, also known as 2-hydroxy-4-(methylthio)butanoic acid (HMTBa), is a synthetic compound used as a methionine source in animal nutrition. It is structurally similar to DL-methionine, an essential sulfur-containing amino acid, but includes a hydroxyl group, giving it unique chemical properties.

In equine nutrition, DL-methionine hydroxy analogue serves as an alternative methionine supplement to support protein synthesis, sulfur amino acid requirements, and metabolic functions involving methylation and antioxidant defense. Methionine is essential for tissue repair, hoof integrity, and the synthesis of compounds like glutathione.

The following equine feeds, supplements and products contain DL-Methionine Hydroxy Analogue as an ingredient.
