Mineral water is a type of bottled drinking water that typically contains extra minerals, including calcium and magnesium. Some brands of mineral water are carbonated, while others remain flat and still. Many people believe that these waters provide more health benefits than regular bottled water, although it’s important to note that each brand adds different vitamins and minerals, so you will need to research which ones your body will absorb best.

Unlike distilled or tap water, which comes from municipal or private wells, mineral water is produced by natural springs. These springs usually originate in igneous, sedimentary or metamorphic rocks and can contain dissolved minerals. Some of these mineral waters are known for their healing properties, and they’re frequently used in spas and health resorts.

Mineral waters are regulated by a number of countries, and can be sparkling (naturally or artificially carbonated) or still (uncarbonated). There is also a wide variation in the amount of minerals – known as Total Dissolved Solids – in each brand of mineral water. This is due to the fact that different geologic sources produce a variety of types of mineral water.

The mineral content in mineral water varies widely, so there is no recommended daily amount. However, studies have shown that the consumption of certain minerals, such as calcium for bone development and magnesium for protection from cardiovascular risk, can be beneficial.

In addition to calcium and magnesium, mineral water is rich in potassium. This mineral is required for muscle function and regulation of the acid-base balance in the body. It is also needed for the production of ATP, an energy source for biological processes.

Some mineral water is rich in sodium, and may be harmful to those who need a low-sodium diet. Some brands of mineral water can also contain microplastics, which are small plastic particles that may be released by the manufacturing process or when the bottle is left in sunlight.

Some mineral water is highly carbonated, and this can be problematic for those with GERD (gastroesophageal reflux disease). The gas bubbles can cause bloating, and they can also increase acidity in the digestive tract. Additionally, some studies have found that carbonated mineral water can irritate the teeth and throat. It is also a poor choice for those trying to quit soda, as it can encourage the formation of tooth decay and tooth erosion. Choosing an uncarbonated mineral water can help alleviate these problems.
