Selenium-enriched balls are made by uniformly mixing nano-selenium micro-powder in clay materials and firing them into ceramic balls, which enables the selenium-enriched balls to effectively and slowly release selenium ions that can be absorbed by the human body.
Advantages: 1. Slow release 2. Stable effect3. Long service life
