The selenium-enriched yeast powder we supply is produced by introducing inorganic selenium (sodium selenite) during the yeast fermentation process. Through subsequent biotransformation by the yeast cells, the selenium is organically sequestered within the yeast proteins and polypeptides-primarily in the forms of selenomethionine and selenocysteine. The product is then obtained as a fine, pale yellow to brownish-yellow powder following a series of processing steps: inactivation, washing, drying, and pulverizing. It possesses the characteristic aroma of yeast and is free of any off-odors.
The total selenium content of this product can be consistently controlled within specified standard ranges according to customer requirements. Typically, the organic selenium fraction constitutes no less than 95% of the total selenium, with selenomethionine serving as its predominant chemical form. Every batch of the product undergoes rigorous testing to verify its total selenium content, organic selenium ratio, selenomethionine levels, heavy metal concentrations, microbiological limits, and pesticide residues, thereby ensuring full compliance with relevant standards for dietary supplements and food fortification.

Benefits of Selenium enriched Yeast Powder
Contains the inherent nutrients of yeast
In addition to selenium, selenium-enriched yeast also contains high-quality protein, B-complex vitamins, minerals, and dietary fiber.
Supports normal immune system function
Selenium serves as an active component of various selenium-containing enzymes, participating in the proper functioning of the body's immune system.
Participates in antioxidant defense processes
As a key constituent of glutathione peroxidase, selenium plays a vital role in cellular antioxidant protection.
Supports normal thyroid function
Selenium is involved in the synthesis and activation of thyroid hormones, helping to maintain the proper functioning of the thyroid gland.
Helps protect cells from oxidative damage
Selenium participates in the body's antioxidant defense system, helping to maintain the structural integrity of cells.
Helps maintain the normal condition of hair and nails
Selenium plays a role in supporting healthy hair and nail structure.
Application Fields
Dietary Supplements
Selenium tablets, capsules, multivitamin blends, and immune support formulas.
Functional Foods
Fortified cereals, nutritional biscuits, beverages, energy bars, and health drinks.

FAQ
Q: How is Selenium Enriched Yeast different from sodium selenite?
A: Selenium yeast contains organic selenium , which is absorbed more efficiently and retained longer in the body than inorganic selenite.
Q: What are the available selenium grades?
A: We offer 1000ppm, 2000ppm, and 3000ppm grades. The 2000ppm grade is the most commonly used for dietary supplements and functional foods.
Q: Is Selenium Enriched Yeast GRAS approved?
A: Yes. Certain selenium yeast products have received GRAS (Generally Recognized as Safe) notification from the FDA for use in human foods, and GRAS approval has also been granted for use in infant formula.
Q: Can I brand it as my own?
A: Yes-we handle private labeling and custom packaging so it looks, feels, and sells like yours.
Q: Can it be used in tablet and capsule formulations?
A: Absolutely. The powder is suitable for direct compression, granulation, capsule filling, and liquid suspensions, as well as incorporation into functional food matrices.
