Although selenium supplementation is necessary, it cannot be taken blindly, and if it is done blindly it may cause side effects. Scientific selenium supplementation methods are: 1, artificial selenium supplementation: ingestion of artificially added all kinds of selenium supplementation products are mainly divided into two categories of inorganic selenium and organic selenium, inorganic selenium is mainly sodium selenite, foreign countries are mostly used for feed use, there are great toxins, as well as on the verge of technological elimination. Compared with inorganic selenium such as sodium selenite, organic selenium has the advantages of safe consumption, non-toxic side effects, high absorption and utilization, and high nutritional value (such as high level of vitamins, high quality protein, etc.). There are many kinds of organic selenium, such as selenium yeast, selenium eggs, selenium-enriched algae, selenium-enriched mushrooms and selenium malt, etc. Among them, selenium malt is the highest stage of organic selenium development at present, which has better activity, higher utilization rate, no accumulation of toxicity and can be taken for a long time than mushroom selenium and yeast selenium.
