Abstract：Selenium polysaccharide is easy to be absorbed by the human body, with small side effects, and has good effects on antitumor, antioxidation, and improving the body’s immunity, which has become a research hotspot in recent years. In this paper, the biological activities of selenium polysaccharide in immunomodulatory, anti-virus, anti-inflammation, and protective activities are reviewed, which provides an effective theoretical basis for its research and application.
