Nongfu Spring only produces natural weak alkaline healthy drinking water, and resolutely opposes adding any artificial minerals to the water. The World Health Organization's drinking water quality guide shows that no matter whether the diet structure is rich or not, the human body must take a certain proportion of minerals and trace elements from drinking water. Therefore, Nongfu Spring believes that drinking water should contain comprehensive, balanced and natural mineral elements needed by human body, and opposes adding any artificial minerals to water.
