We supply as under:
Sodium Selenite is an inorganic form of the trace element selenium with potential antineoplastic activity. Sodium selenite appears as a white colored crystalline solid, soluble in water. It has a role as a nutraceutical. Because selenium is an essential element, sodium selenite is an ingredient in dietary supplements such as multi-vitamin/mineral products. The USA Food and Drug Administration approved a selenium supplement to animal diets; the most common form is sodium selenite for pet foods. It is also approved addditive in dietary supplements in limited quantities.
