In general, its chemical composition, flow rate, water temperature and other dynamic indicators are relatively stable in the natural periodic fluctuation range, and it is a rare mineral resource.
3. Apple vinegar beverage is an acidic beverage, which is alkaline after metabolism in human body. Although the mouth is sour, these organic acids are decomposed into carbon dioxide and various acidic salts in the body and become alkaline, which can effectively improve the acidic constitution of the human body and make the human body weakly alkaline.
