The unique digestive benefits of mineral water stem from its mineral content. Bicarbonate neutralizes excess stomach secretions and gives immediate relief from heartburn. Magnesium controls the bowel habit and allays constipation. Calcium facilitates the functions of enzymes so that food is broken down efficiently. The proper functioning of the digestive system is achieved through the proper combination of minerals.

Acid Neutralization

  • Bicarbonate creates optimal pH for enzyme activity
  • Reduces heartburn symptoms within minutes
  • Protects stomach lining from acid damage

Bowel Regulation

  • Magnesium draws water into intestines preventing constipation
  • Improves peristalsis for regular bowel movements
  • Reduces bloating and abdominal discomfort

Nutrient Absorption

  • Calcium activates digestive enzymes
  • Creates alkaline environment for better nutrient uptake
  • Enhances protein and fat digestion efficiency

Research shows mineral water improves digestion. Subjects showed 50% less acid reflux symptoms while taking the mineral water. Subjects in the test showed less constipation. In my experience, it is best to drink mineral water before meals, as it helps prepare the digestive system for the meal ahead. The digestive system functions optimally when supplemented with a mineral source in the usual diet.

The bicarbonate and magnesium work in a synergistic way to yield lasting effects on digestion. Bicarbonate neutralizes acidity quickly, while magnesium yields more permanent regulation. Calcium allows for continuous enzyme support. This combination of minerals gives far better relief than antacids, which only act transiently. Your digestive system is kept in perfect equilibrium.

For maximum benefit, opt for high-bicarbonate mineral waters, such as Gerolsteiner, which contain more than 1,800 mg/L of bicarbonate. Drink 500ml thirty minutes before eating. Avoid carbonated mineral waters if you find you get bloated. Your digestion will improve with proper mineralisation.
