Water's Good

Mineral Water: Healthy or Equal to Tap Water?

Posted On 06/24/2024 By iSpring Water Systems

While all water contains minerals, what sets mineral water apart is that it features naturally occurring minerals and contains a minimum of 250 parts per million of total dissolved solids to meet FDA standards. Also, because it’s bottled straight from its underground source, it does not undergo chemical processing. 


It’s important to keep in mind: all mineral water is not created equally. The mineral content is dependent on the source, and each one has a unique composition. The most commonly occurring minerals in water sources are magnesium, calcium, and sodium. However, many mineral waters can also include zinc, iron, potassium, and bicarbonate which can be beneficial to your overall health. 


Why Mineral Water? 

Mineral water contains minerals that are essential for overall health. However, don't overlook tap water as it also contains similar minerals because treatment plants will enhance water with essential minerals during the treatment process. Though the content is not dissimilar, the primary difference between mineral water and tap water is how the minerals came to be in the water. 


While consuming water with high mineral content effortlessly aids you in ensuring these are included in your daily diet, you can also get these minerals through food and supplements, making the necessity of mineral water less important.


Benefits of the Minerals Commonly Occurring in Mineral Water

Magnesium, calcium, and sodium are the three most common minerals found in underground reservoirs where mineral water is derived. Each of these minerals plays an important role in maintaining a healthy system. 


Both bottled mineral water as well as tap water contain magnesium, which aids in regulating blood pressure, blood glucose levels, and nerve function. Maintaining the recommended levels of magnesium can lower the overall risk of cardiovascular disease. Magnesium also aids in digestive help by drawing water into the intestines and helping reduce constipation. 


Magnesium, along with calcium and potassium also work to help blood circulation and all are commonly found in mineral water. Calcium is also widely known to be important for bone health, but magnesium also helps bone density. 


Concerns with Mineral Water

One concern with mineral water is that when considering babies, some natural mineral water contains too much sodium or sulfate, which may not be suitable for infants due to their developing kidneys and digestive systems. Excessive intake of these minerals can potentially damage a baby's organs or cause imbalances in their delicate electrolyte levels. Therefore, it's crucial for parents to carefully check the label to make sure the figure for sodium (sometimes labeled as Na) isn’t higher than 200 milligrams (mg) a liter. Sulphate shouldn’t be higher than 250 mg/l. You might need to look for ‘SO’ or ‘SO4’ on the label as these also mean sulfate.


Another concern is specifically related to those with high blood pressure or those following low-sodium diets. These individuals would likely want to steer clear of mineral water to avoid consuming additional sodium unnecessarily. Also, like any carbonated beverage, drinking sparkling mineral water can break down the enamel on teeth. 


One of the larger concerns, and something that is a part of iSpring’s mission, is the environmental impact of single-use plastics. Here at iSpring, we are focused on reducing single-use plastics. Not only can these single-use plastics be bad for the environment, but they can also put consumers at unnecessary health risks if they contain microplastics, which enter the body and could potentially cause negative health effects. 


The iSpring Difference 

Taking into consideration mineral water’s composition is not that dissimilar of tap water, consumers have to determine what is truly important when it comes to the water they’re consuming. Our reverse osmosis (RO) water filtration systems use a powerful RO membrane to filter out over 99% of contaminants that may be lurking in your water including vinyl chloride, chlorine, fluoride, lead, arsenic, asbestos, calcium, sodium, and more, making it far superior to both mineral water and tap water in many ways. 


The below-recommended systems also have the ability to add healthy minerals back into your water safely and without the use of plastics. 


Our RCD100HCG is a portable countertop reverse osmosis water filtration system that provides consumers with effortless high-quality water with no installation required. This system also

  1. is comprised of a stainless steel filter, PP CTO composite filter, RO membrane, and alkaline filter
  2. provides up to 100 gallons per day of great-tasting pH-balanced water with its alkaline filtration stage
  3. has hot & cold temperature options and 6 dispensing volume options
  4. features a 2.5:1 pure-to-drain water ratio
  5. has real-time monitoring of source water and filtered water TDS levels, along with a temperature display and a low water level reminder
  6. offers a 10-second auto-flush process upon opening or closing the source water tank cover, extending the lifespan of filters
  7. includes filter life monitoring and features a twist-and-lock design for easy filter replacements
  8. features dual pitchers, allowing you to have constant filtered water at your fingertips

Our RO500AK-BN is the next-generation, tankless reverse osmosis system. It also uses an alkaline RO filter system and

  1. is NSF/ANSI 58 certified
