Mineral Water vs Normal Water: What's the Real Difference?

Water is essential for life, but the type of water you drink matters more than you might think. While tap water goes through municipal treatment processes, mineral water contains naturally occurring minerals like calcium, magnesium, and potassium that are absorbed as the water flows through underground rock formations.

Key Differences

  • Mineral Content: Mineral water contains at least 250 parts per million (ppm) of total dissolved solids (TDS), including essential minerals. Regular water typically has a lower TDS.
  • Source: Mineral water comes from protected underground sources, while normal water can come from any surface or underground source.
  • Treatment: Mineral water undergoes minimal processing to preserve its natural mineral composition, whereas tap water is heavily treated with chlorine and other chemicals.
  • Taste: The mineral content gives mineral water a distinct, often smoother taste compared to regular water.

Health Benefits of Mineral Water

Studies have shown that regular consumption of mineral water can help maintain bone density due to its calcium content, support cardiovascular health through magnesium, and aid in maintaining proper electrolyte balance. The naturally occurring bicarbonates in mineral water also help with digestion.

Which Should You Choose?

For daily hydration, mineral water offers superior health benefits. At P.T. Healthcare, our Bislaim brand undergoes a rigorous 7-stage purification process while retaining essential minerals, giving you the best of both worlds — purity and nutrition.
