DL-Selenomethionine Powder
What is DL-Selenomethionine Powder?
Selenomethionine is an organic compound formed by the combination of selenium and methionine, belonging to the naturally occurring organic selenium form. It has high bioavailability in the human body and effectively participates in the operation of the antioxidant system, immune regulation, and thyroid function support, making it one of the essential nutrients for maintaining health.
In the molecular structure of selenomethionine, the selenium atom replaces the sulfur atom in methionine, forming a stable organic selenium form. This structure allows it to be directly integrated into human proteins and slowly released into tissues, prolonging its duration of action. Compared with inorganic selenium (such as sodium selenite), it has a higher absorption rate and safety profile, and is less irritating to the gastrointestinal tract.
Feature
Core of the Antioxidant Defense System
It is a key raw material for the synthesis of glutathione peroxidase. This enzyme is one of the most important antioxidant enzymes in the body, powerfully scavenging free radicals and protecting cell membranes and DNA from oxidative damage. It has a synergistic antioxidant effect with vitamin E, jointly forming the body's antioxidant defense line.
Supports Immune System Function
Selenium can stimulate the activity and proliferation of immune cells (such as B cells and T cells), enhancing the body's resistance to viruses and bacteria. Adequate selenium levels are essential for maintaining healthy immune function.
Regulates Thyroid Hormone Metabolism
It is an essential component for the activation of thyroid hormones and deiodinase. It can promote the conversion of thyroid hormone (T4) into its active form (T3), thereby maintaining normal thyroid function and the body's metabolism.
Protects Cardiovascular and Liver Health
Through its antioxidant effects, it reduces the damage of oxidative stress to vascular endothelial cells and myocardial cells. It has an auxiliary protective effect against chemically induced liver damage.
Applications
Animal Nutrition and Livestock Industry
Feed Additives: As a highly efficient and safe source of selenium, added to the feed of pigs, chickens, cattle, and aquatic animals.
Improving Animal Health and Product Quality: Aimed at enhancing animal immunity and reproductive performance, while increasing the selenium content in meat, eggs, and milk to produce selenium-enriched foods.
Human Nutrition and Health
Dietary Supplements: As a high-end organic selenium supplement, for use by individuals deficient in selenium or requiring additional supplementation, such as the elderly and those with weakened immune systems.
Health Food Raw Materials: Used in the development of health foods with antioxidant, immune-boosting, and liver-protective functions.

Package & Storage
Our packing method is 1KG/Aluminium bags, 25kg/drum
For some products that require special packaging during transportation, we will carry out more delicate packaging. For example, retinal needs to be stored at -20 °C, so we choose cold chain transportation during transportation; deoxyarbutin will change color during transportation, so we will Vacuum packing of deoxyarbutin
