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
