My friend has good taste. Xianyu Selenium Spring is a selenium-enriched natural spring of Suzhou Xianyu Selenium-enriched Food Company. It originated from Dashan Village, the first selenium-enriched longevity village in China, and is a key eco-tourism scenic spot in Anhui Province, the first eco-economic demonstration area in China and a production base of pollution-free agricultural products. Its taste is delicate, and it contains the index elements and components of natural mineral water such as strontium, lithium, zinc, bromine, iodine, metasilicic acid and carbon dioxide. What's more commendable is that the water quality is rich in selenium, an essential trace element for human body. Drinking this water all year round can prevent cancer and health care, and prevent many diseases.
