DL-Selenomethionine Food Quality Grade Powder Wild Cultivation Selenium CAS 1464-42-2 Plant Extract Product

1.  Description

Chemical properties: DL Selenomethionine belongs to the class of selenium containing amino acid compounds, with a molecular structure similar to methionine. It replaces the sulfur atom in the methionine molecule with selenium atoms and is a DL racemate (including D-selenomethionine and L-selenomethionine). Chemical properties are stable, not easily oxidized or decomposed, and can exist stably in neutral to weakly acidic environments. Most of the activity can still be retained during high-temperature processing.
       Physical properties: DL Selenomethionine is a white to off white crystalline powder at room temperature, odorless and tasteless, with good water solubility. It can quickly dissolve in aqueous systems such as pure water and physiological saline, as well as in acidic solutions such as dilute hydrochloric acid and acetic acid. It is slightly soluble in ethanol and insoluble in non-polar solvents such as ether and petroleum ether. Store stably under dry, sealed, and dark conditions, avoiding contact with strong oxidants and heavy metal ions.
       Source and preparation: DL Selenomethionine naturally exists in small amounts in selenium rich plants (such as selenium yeast, selenium rich grains), animal tissues, and seafood. In industry, it is mainly prepared by chemical synthesis method, using methionine as raw material to obtain racemic products through selenization reaction, or by microbial fermentation method (such as yeast fermentation) to produce selenium rich yeast extract, which is then separated and purified. The purity of the synthesized product is high (≥ 98%), and the biocompatibility of the fermented product is better.

2.  Application

         In the field of dietary supplements, DL Selenomethionine, as a highly efficient organic selenium supplement core ingredient, is used to develop formulations such as capsules, tablets, oral liquids, etc., targeting selenium deficient populations, those concerned with immune health, antioxidant and thyroid function maintenance. The absorption efficiency of its organic selenium form is much higher than that of inorganic selenium (such as sodium selenite), making it suitable for daily selenium supplementation, health preservation, and other scenarios.
      In the field of feed additives, DL Selenomethionine is widely used in feed formulations for livestock, poultry, and aquaculture as an animal nutrition enhancer. It can enhance the immunity, reproductive performance, and stress resistance of farmed animals (such as chickens, pigs, fish, and shrimp), while improving the selenium content and quality of animal products (meat, eggs, and milk), meeting the requirements of green farming.
      In the fields of scientific research and medicine, DL Selenomethionine is used for research on selenium metabolism mechanisms, antioxidant stress, and tumor prevention. In scientific research, cell and animal models are used to explore their effects on selenoprotein synthesis, redox balance, and disease-related pathways, providing experimental evidence for intervention studies on selenium deficiency related diseases.

3. Main Efficacy

Efficient selenium supplementation effect: DL Selenomethionine, as an organic selenium source, can efficiently absorb its amino acid structure through intestinal amino acid transporters, with an absorption rate of over 80%, far higher than inorganic selenium. Selenium is an essential trace element for the human body, involved in the synthesis of various selenium proteins such as glutathione peroxidase and thyroxine deiodinase, and is key to maintaining normal physiological functions of the body.
       Antioxidant and cell protective effects: DL Selenomethionine participates in the synthesis of glutathione peroxidase, which can clear reactive oxygen species (ROS) and lipid peroxides in the body, reducing oxidative stress damage to cells; At the same time, it protects the integrity of cell membranes, proteins, and DNA from oxidative damage, delays cell aging, and has a protective effect on organs such as cardiovascular and liver.
      Immune regulation and metabolic support effects: DL Selenomethionine regulates the activity of immune cells (such as lymphocytes and macrophages), promotes the secretion of immune factors (such as IL-2 and TNF - α), and enhances the body's immune response to infections and tumors; Simultaneously participating in thyroid hormone metabolism, maintaining stable thyroid function, and assisting in regulating energy metabolism.
      Optimization effect of animal farming: DL Selenomethionine can enhance the disease resistance of farmed animals and reduce the occurrence of diseases such as diarrhea and respiratory infections; Promote the secretion of growth hormone, improve feed conversion rate and growth rate; Improve reproductive performance, increase egg production rate, hatching rate, and piglet survival rate, while increasing selenium content in animal products to enhance nutritional value.
