Mineral water contains large quantities of magnesium, calcium, sodium, and other beneficial minerals.
Studies suggest that drinking mineral water may have health benefits, though little research directly suggests that it is better for a person’s health than tap water.
People who want to buy mineral water can find it in supermarkets or choose from brands online.
Also, in the U.S., the EPA strictly regulates tap water quality to ensure that it is free from harmful microbes. Tap water also contains added minerals, making it a cheaper alternative to mineral water.
Drinking carbonated mineral water may cause some tooth erosion, but not to the same extent as sugar-sweetened beverages such as sodas.
Mineral content in tap water varies by location. People in the U.S. can check the EPA’s water quality reports by state. These annual reports contain information about water sources, levels of contaminants, and mineral contents.
