Product Overview

Sodium Selenite is an inorganic selenium ingredient used as a trace mineral source in nutritional and feed formulations.

Also known as
Selenious Acid Sodium Salt, Sodium Selenite Anhydrous

Description
Sodium Selenite is a water-soluble inorganic selenium compound widely used as a trace element source in both human nutrition and animal feed formulations. It provides selenium in a stable mineral form suitable for controlled fortification of premixes and nutritional products.

From a B2B ingredient perspective, Sodium Selenite is valued for its consistent selenium concentration, stable quality profile, and compatibility with large-scale premix production. The compound is typically supplied as a white to off-white crystalline powder with defined selenium content levels.

Manufacturers use Sodium Selenite in mineral premixes, fortified nutritional products, and animal feed additives where controlled selenium supplementation is required. Due to its high selenium content, precise dosage and uniform mixing are essential during formulation.

Available Specifications
Sodium Selenite is typically supplied in grades standardized by selenium content (commonly 44–46% Se). Industrial and feed-grade materials are available with controlled heavy metals, moisture limits, and particle size distribution suitable for premix and additive manufacturing.

Applications

Dietary Supplements
Sodium Selenite can be used for selenium fortification in multivitamin and mineral supplement formulations.

Functional Nutrition
Sodium Selenite can be used as a trace mineral source in fortified nutrition powders and functional nutrition blends.

Sports / Active Nutrition
Sodium Selenite can be used as a selenium micronutrient source in advanced nutritional formulations supporting metabolic and antioxidant systems.

Pharmaceutical / Medical
Sodium Selenite can be used as a selenium ingredient in pharmaceutical formulations and medical nutrition products where controlled trace mineral dosing is required.
