Selenium Rich Yeast Powder

Premium Bioavailable Trace Element by Xi'an Tihealth

Formulating with inorganic selenium (such as sodium selenite) presents significant challenges regarding toxicity, poor absorption, and gastrointestinal irritation. Xi'an Tihealth resolves this with our pharmaceutical and food-grade Selenium Enriched Yeast Powder, the gold standard for safe, high-bioavailability trace element supplementation.

Through a highly controlled submerged fermentation process using premium Saccharomyces cerevisiae strains, inorganic selenium is naturally biotransformed into stable, organic Selenomethionine and Selenocysteine. This yields a nutrient-dense powder containing up to 2500 mg/kg of organic selenium, alongside naturally occurring yeast proteins (≥ 45%), B-vitamins, and beta-glucans. With an organic conversion rate exceeding 98%, our extract provides formulators with an incredibly safe, non-toxic, and highly bioactive foundation for premium immunity capsules, Foods for Special Medical Purposes (FSMP), and advanced animal nutrition.

For R&D nutritionists and feed formulators, the chemical form of selenium directly dictates its safety margin and physiological efficacy. Our fermented yeast extract delivers profound B2B advantages:

•  
• Superior Bioavailability (Active Transport):
• Inorganic selenium is absorbed passively and poorly retained. The organic Selenomethionine in our yeast is recognized by the body as an amino acid. It utilizes active transport mechanisms, resulting in absorption and tissue retention rates that are roughly double those of sodium selenite.
•  
• Unmatched Safety Profile (Low Toxicity):
• Inorganic selenium carries a narrow therapeutic window and strict toxicity risks. Our organic biotransformation mitigates this hazard entirely, preventing gastrointestinal stress and ensuring a vastly superior safety profile for pediatric, senior, and veterinary applications.
•  
• Nutritional Synergy (Yeast Matrix):
• You are not just adding a single trace mineral. The yeast cell matrix naturally supplies high-quality complete proteins, essential B-vitamins (B1, B2), and immune-supporting polysaccharides, offering a multi-dimensional nutritional boost to your end product.

Batch-to-batch consistency and the strict control of residual inorganic selenium are critical for regulatory compliance. Below is the analytical data sheet for our standard 2000 ppm specification.

Replacing non-compliant disease-treatment claims with scientifically validated biological mechanisms, this organic trace element supports premium formulas targeting:

• Dietary Supplements & Nutraceuticals:
• The primary active ingredient in immunity-boosting capsules, thyroid support multivitamins, and anti-aging antioxidant formulas.
•  
• FSMP (Foods for Special Medical Purposes):
• Officially approved in multiple international markets as a safe, highly tolerated selenium source for clinical nutrition and post-operative recovery blends.
•  
• Functional Foods & Dairy Fortification:
• Easily blended into fortified milk powders, nutritional biscuits, and solid beverages to enhance their mineral claims.
•  
• Advanced Animal Nutrition & Aquaculture:
• Widely utilized in premium livestock and poultry feed to drastically improve meat quality (reducing drip loss), boost reproductive fertility, and enhance disease resistance in high-density aquaculture.

Our extraction methodology guarantees the complete conversion of toxic inorganic elements into safe, bioactive organic molecules:

1.  
2. Strain Selection & Cultivation:
3. We utilize highly specialized, selenium-tolerant strains of Saccharomyces cerevisiae (Baker's Yeast).
4.  
5. Submerged Fed-Batch Fermentation: The yeast is cultured in large fermentation tanks. Inorganic selenium (sodium selenite) is carefully and progressively dosed into the nutrient broth. The growing yeast absorbs the selenium, substituting sulfur with selenium in the synthesis of amino acids (creating Selenomethionine).
6.  
7. Centrifugation & Rigorous Washing:
8. The fermented yeast cream is centrifuged and repeatedly washed with purified water. This is a critical QC step that entirely removes any unabsorbed, free-floating toxic inorganic selenium from the batch.
9.  
10. Autolysis & Pasteurization:
11. The yeast cells are gently autolyzed (broken down) and subjected to high-temperature pasteurization. This completely inactivates the yeast (ensuring no continued fermentation in your product) while preserving the protein and organic selenium structures.
12.  
13. Spray / Vacuum Drying:
14. The purified yeast cream is rapidly dried into a stable, fine powder and immediately packaged to prevent moisture ingress.

Operating under an ISO9001:2015 Quality Management System, Xi'an Tihealth utilizes high-barrier packaging to ensure the integrity of your trace minerals during global transit.

How do you prove that the selenium is actually organic?

This is the most critical quality metric for Selenium Yeast. Using advanced HPLC-ICP-MS testing, our QA lab analyzes every batch to distinguish between organic (Selenomethionine) and inorganic (selenite) forms. We strictly guarantee that the Organic Selenium Ratio constitutes ≥ 98.0% of the total selenium, with residual inorganic selenium kept strictly below 2.0%.

Can this powder cause further fermentation or gas in my product?

No. During our downstream processing, the yeast is subjected to a rigorous, high-temperature pasteurization step. This completely inactivates the yeast cells. It is biologically "dead" and will not cause any fermentation, gas production, or spoilage in your final capsules, foods, or liquid formulations.

Why is this preferred in premium animal feed over cheaper Sodium Selenite?

Sodium selenite is a toxic heavy metal salt that causes severe oxidative stress in the animal's gut and is poorly absorbed. Organic Selenium Yeast is absorbed actively as an amino acid, accumulating in the animal's muscle tissue. This drastically reduces the feed toxicity risk, improves meat quality (reduces drip loss), and enhances the reproductive health of the livestock.
