Methods of supplementing selenium:
1, inorganic selenium: toxic, the toxic dose is very close to the human body's needs, so its use is strictly restricted.
2. Organic selenium: high absorption and utilization rate of human body, strong biological activity and little side effect.
Selenium-fortified food is fortified by adding selenium fortifier to dairy products, biscuits, cereals and other foods. The Standard for the Use of Nutritional Fortifiers in Foods clearly stipulates the types of foods fortified with selenium and the dosage of nutritional fortifiers.
Selenium in selenium-enriched foods exists as organic selenium similar to natural foods, such as selenomethionine and selenocysteine, which can not only improve the physiological activity and absorption rate of selenium, but also reduce its toxicity. This method is considered to be the safest and most effective method to improve selenium nutrition.
