Selenomethionine Powder

 

Selenomethionine powder, abbreviated as SeMet, is an organic selenium compound formed by the replacement of the sulfur atom in methionine by selenium. It is one of the main storage and transportation forms of selenium in organisms.

 

It has high bioavailability, with an absorption rate of more than 90% in the human body, because it is actively absorbed through the intestinal amino acid transport system. And its half-life is long, which can slowly release selenium and avoid sudden rise and fall in blood selenium concentration.

1. Antioxidant
As a selenium source for glutathione peroxidase and thioredoxin reductase, it directly removes free radicals and protects cell membranes from oxidative damage. It is often used in combination with vitamin E to significantly enhance its ability to resist lipid peroxidation.

 

2. Immunomodulatory
Selenomethionine powder can promote T cell proliferation and antibody production, especially for the elderly and those with low immune function. Recent studies have found that it may regulate inflammatory factors through selenoprotein S.

 

3. Thyroid hormone metabolism
As an essential component of iodothyronine deiodinase, it regulates the conversion of T4 to active T3 and maintains the balance of thyroid function.

 

 

1. Nutritional supplements
Safety: Its maximum tolerable intake is 400 μg/day. Excessive intake may cause selenium poisoning and hair loss. It can be combined with zinc and vitamin D.

 

2. Agriculture and feed additives
As a source of selenium for animals, selenomethionine powder can increase the selenium content in meat and is less toxic than sodium selenite.

 

3. Cancer prevention research
Studies have shown that it may reduce the risk of prostate cancer. However, the association between a high-selenium diet and the risk of type 2 diabetes remains controversial and more research is needed.
