Sodium Selenite, anhydrous Applications

Selenium is an essential trace element that plays a vital role in numerous physiological processes in the human body. It is a structural component of several selenoproteins, which are crucial for protecting cells, regulating metabolism, and maintaining the immune and hormonal systems.

Key Biological Functions of Selenium

Antioxidant Protection:
Selenium forms part of the enzyme family glutathione peroxidases (GPx), which neutralize harmful peroxides and protect cells and tissues from oxidative stress. This function safeguards cell membranes, lipids, and DNA from damage caused by reactive oxygen species.
Thyroid Hormone Regulation:
Selenium is required for the activity of deiodinase enzymes, which convert inactive thyroxine (T₄) into the active thyroid hormone triiodothyronine (T₃). Adequate selenium levels are therefore essential for proper energy metabolism and hormonal balance. This can support proper thyroid function, helping to alleviate issues like hypothyroidism or Hashimoto's thyroiditis, which are more prevalent in women.
Immune Function:
Selenium supports immune cell activity, enhances antibody formation, and helps regulate inflammation. It contributes to the body’s defense against infections and oxidative damage.
Reproduction and DNA Maintenance:
Selenium is involved in sperm formation and in the protection and repair of DNA, contributing to overall cellular health and genetic stability. Based on studies Selenium plays a role in female fertility and reproductive health. It can support the function of the ovaries and the development of healthy eggs, potentially contributing to improved fertility.

Because the human body cannot synthesize selenium, it must be obtained from external sources. In pharmaceutical and nutritional applications, sodium selenite (Na₂SeO₃) is the most commonly used inorganic selenium compound. It is water-soluble, chemically stable, and efficiently converted into biologically active selenium forms in the body.

Nutritional Applications

Sodium Selenite, anhydrous is widely used as a selenium source in dietary supplements and fortified foods. Selenium is an essential trace element that supports immune function, antioxidant defense, and thyroid metabolism.

Pharmaceutical Applications

In pharmaceutical formulations, Sodium Selenite is applied as an active ingredient in therapeutic products. It is used in drugs aimed at treating or preventing selenium deficiency-related conditions, as well as in formulations where selenium contributes to antioxidant protection and immune health. Its well-defined chemical profile ensures reliable integration into strict pharma-grade applications.

FAQ Sodium Selenite, anhydrous

1. What is sodium selenite?

Sodium selenite is an inorganic form of the trace element selenium, often used in supplements and fortification. It appears as a white or colorless crystalline powder.

2. What is sodium selenite used for?

It is used to prevent or treat selenium deficiency, support antioxidant activity, and contribute to healthy immune function and thyroid function.

3. How should sodium selenite be taken?

It is usually taken orally in capsule, tablet, or liquid form.

4. What is a safe dosage for adults?

The recommended daily intake for adults is typically around 55 micrograms of selenium per day. Excessive intake should be avoided, as it can be toxic. Sodium selenite supplements usually provide controlled amounts within this range. The tolerable upper intake level (UL) is 300 micrograms of selenium per day.

5. Can sodium selenite be taken during pregnancy or breastfeeding?

Yes, but only at recommended daily doses. Pregnant and breastfeeding women should consult a healthcare professional before supplementation.

6. Are there any side effects of sodium selenite?

At recommended doses, it is usually safe. High doses can cause nausea, hair loss, fatigue, irritability, or gastrointestinal discomfort.
