Product Overview
W&Q's Sodium selenite (molecular formula: Na₂SeO₃) is a water-soluble inorganic selenium compound, presenting as white crystalline powder. As an essential trace mineral supplement, it plays a crucial role in human and animal metabolism. W&Q adheres to strict GMP and ISO certification standards in the production of sodium selenite, using high-purity raw materials and advanced reaction processes to ensure the product’s stability, solubility, and safety. Our sodium selenite is widely applied in dietary supplements, pharmaceutical formulations, and animal nutrition, providing a reliable selenium source for global customers.
Product Benefits
1. Powerful Antioxidant Protection: Selenium, the core component of sodium selenite, is an essential cofactor for antioxidant enzymes such as glutathione peroxidase (GPX) and thioredoxin reductase. These enzymes effectively scavenge free radicals and lipid peroxides, reducing oxidative stress and protecting cell membranes from damage. W&Q’s sodium selenite ensures optimal bioavailability, helping to enhance the body’s antioxidant capacity.
2. Immune Function Enhancement: Sodium selenite modulates the balance of immune cells, strengthens the phagocytic activity of NK cells and macrophages, and improves the body’s response to pathogens and vaccines. Clinical studies have shown that appropriate selenium supplementation can increase antibody titers in the elderly, enhancing immune resilience.
3. Thyroid Health Support: Selenium is necessary for the activity of 5′-deiodinase, which converts inactive T4 thyroid hormone to active T3. W&Q’s sodium selenite helps maintain normal thyroid function, supporting metabolism regulation and overall endocrine balance, especially beneficial for individuals with thyroid disorders.
4. Potential Health Maintenance: Research indicates that sodium selenite may help reduce the risk of certain cancers by inhibiting tumor cell growth and inducing apoptosis. It also supports cardiovascular health by mitigating oxidative damage to blood vessels.
Usage
- Dietary Supplements: For adult daily use, the recommended dosage is 50-60 μg of selenium (equivalent to appropriate sodium selenite content). W&Q provides customized formulations (tablets, capsules, powders) to meet different supplement needs, with dosages adjustable based on age, health status, and regional selenium intake levels.
- Pharmaceutical Applications: As a prescription drug, it is used for preventing and treating selenium deficiency-related diseases (such as Keshan disease, Kashin-Beck disease) and assisting in the management of cardiovascular diseases and certain cancers. Dosage must be prescribed by a physician, with typical oral administration of 1-2 mg per day for adults (11 years old and above).
- Animal Nutrition: Widely used in livestock and poultry feed to improve selenium levels in animals, enhance immunity, and promote growth performance. The recommended addition level varies by animal species and growth stage, with W&Q providing technical guidance for optimal usage.
Storage: Keep in a dry, well-ventilated place, avoid moisture and direct sunlight, and store separately from toxic and harmful substances. The shelf life is 24 months when stored as directed.
FAQ
Q1: Is sodium selenite toxic? What is the safe dosage?
A1: Selenium is toxic in excessive doses. The daily maximum safe intake for humans is 300-400 μg. Acute or chronic poisoning (vomiting, abdominal pain, alopecia, etc.) may occur if the daily dosage exceeds 1 mg. W&Q’s products are formulated within safe limits, and strict dosage adherence is recommended.
Q2: Is sodium selenite less effective than organic selenium?
A2: Organic selenium has slightly higher bioavailability, but sodium selenite offers excellent stability, lower cost, and reliable efficacy. It can fully meet the body’s selenium needs and is widely approved by global regulatory authorities (such as China GB 14880-2012, EU Reg. 1925/2006). W&Q’s sodium selenite ensures consistent quality to maximize effectiveness.
Q3: Can patients with kidney disease take sodium selenite?
A3: Moderate to severe kidney disease patients have impaired selenium excretion capacity. They should monitor blood selenium levels and kidney function regularly, and take sodium selenite under the guidance of a physician to avoid accumulation.
Q4: How does sodium selenite interact with other nutrients?
A4: It can enhance the antioxidant effect of vitamin E. No significant negative interactions with other nutrients have been reported, but concurrent use of multiple selenium supplements should be avoided to prevent excessive intake.
