1, composition and absorption effect: amino acid selenium is an organic selenium supplement with amino acid as carrier, which has good bioavailability and absorption effect. Selenium is a trace element, and its absorption and utilization are very important to human health. In contrast, malt selenium is a selenium supplement with malt as the main component, and its absorption effect is not as good as amino acid selenium.

2. Stability and storage mode: amino acid selenium has good stability in the preparation process, and can maintain the activity and effectiveness of selenium. However, malt selenium is easily affected by oxidation or other factors during storage, which leads to the decline of selenium activity. Amino acid selenium has more advantages in stability.
