What is mineral water?

What is mineral water?

March 19, 2025

Drinking high-quality water is always a good idea. But what water is best to drink? If you’re currently drinking unfiltered tap water it might not be doing enough for your hydration and health. Moreover, this water supply might not have the delicious taste you need to keep away from a midday soda. 

At the end of the day, you deserve a water solution that drives hydration and promotes health. We’re taking a closer look at mineral water and why you might consider drinking more of it. 

Where mineral water comes from

Mineral water can be both naturally occurring and manufactured. Natural mineral water originates from underground sources, often aquifers, where it goes through a unique journey absorbing minerals like calcium, magnesium, and potassium. Because natural mineral water sources are located in isolated and well-guarded areas underground, they’re protected from pollution — preserving the water’s purity.

Manufactured mineral water, on the other hand, involves adding minerals to purified water to recreate its mineral-rich composition. This deliberate mineral infusion process supports consistency, customization, and availability. 

The nutritional facts of mineral water

Similar to plain water, mineral water is considered calorie-free. And while its mineral composition varies across brands — with labels indicating “low” or “high” mineral content — there are a few common ones you can expect in these water supplies. According to the U.S. Department of Agriculture, a typical 8 oz. glass of mineral water contains the following nutrients:

  • Calories: 0 calories (cal)
  • Fat: 0 grams (g)
  • Carbohydrates: 0 g
  • Fiber: 0 g
  • Sugar: 0 g
  • Protein: 0 gr
  • Calcium: 79.2 milligrams (mg), 6% of the daily value (DV)
  • Magnesium: 26.4 mg, 6% of the DV
  • Sodium: 31.2 mg, 1% of the DV
