What is Selenium?
With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives.

Selenium exists in nature in two ways: inorganic selenium and plant-active selenium. Inorganic selenium generally refers to sodium selenite and sodium selenate, obtained from by-products of metal deposits; The latter is formed by the combination of selenium with amino acids through biotransformation, generally in the form of selenium methionine.
