Only nature has the absolute best methods of purifying water, and Smartwater understands that concept. They use the most natural filtration process possible. First, they start with fresh spring water. The water they use is already fresher and purer than tap water, but they want to go farther. They heat the water and turn it into vapor before distilling it back to a liquid in a separate sterile container, leaving behind all the contaminants. The result is water that is just as pure as nature intended. Potassium, calcium, and magnesium are then added to the purified water in order to increase alkalinity and nutrient content. Each mineral acts as an electrolyte in the human body, so they are very important to high-quality health. Once the water has reached the perfect level of alkalinity, it is bottled and distributed for sale. Smartwater has a crisp, smooth taste that feels soft and bright on the tongue.
