Degree of mineralization of water

Degree of mineralization of water

Water, which constitutes 55 to 60% of the human body mass, is extremely important for the human organism. It is responsible for proper blood circulation, regulates heat, supports digestive processes, and affects many other vital functions. Therefore, it is worth ensuring that we consume it in good quality and appropriate amounts, which is crucial for health and well-being.

What is water mineralization?

The total mineralization of water determines the amount of compounds and mineral components dissolved in the water. By understanding the saturation of water with mineral salt ions, we cancreate the following division:

It's worth remembering: Low-mineral waters are a good choice for those who prefer milder flavors and do not need additional minerals in their diet.
  • very low-mineral water – below 50 mg/l;
  • low-mineral water – 50-500 mg/l;
  • watermedium mineralized – 500-1500 mg/l;
  • highly mineralized water – 1500 mg/l and more.

Very low mineralized and low mineralized waters

The first of these, namely very low mineralized and low mineralized waters, are spring waters that can be consumed in practically unlimited quantities. They constituteone ideal base for preparing meals for children or infants, and when there is suspicion about their questionable quality, they can be easily boiled. These waters are characterized by low mineral content, making them safe for the delicate digestive system of children.

Medium mineralized waters

The second group consists of watersmoderately mineralized, which can serve a preventive function by maintaining the appropriate level of mineral components in the body. Children under 3 years of age should avoid it, while there are no major contraindications for adults. These waters can be beneficial for people leading an active lifestyle, as they provide essential minerals that support the body's regeneration.

It's worth remembering: WatersModerately mineralized waters are a good solution for adults who need additional support in their daily diet.

Highly mineralized waters

The last group includes highly mineralized waters, which, in addition to mineral salts, also contain healing water. Since they are located in underground, deeply situated aquifers, they...the negative impact of external factors is minimized. Highly mineralized water should be consumed by individuals with mineral deficiencies and those who exercise regularly. On the other hand, it is not suitable for pregnant women, breastfeeding mothers, and children. Unlike low-mineralization liquids, highly mineralized waters should not be boiled, as this causes sedimentation of scale. It is also worth remembering that their regular consumption can support processesdetoxification of the body.

What do mineral waters contain?

The most important components of mineral waters are:

It is worth remembering: Highly mineralized waters can be helpful in replenishing mineral deficiencies, but they should be used with caution.
  • sodium – positively affects the functioning of the heart muscle, as well as regulates water-electrolyte and acid-base balance;
  • potassium – supports the circulatory and nervous systems, provides oxygen essential for proper brain function, and improves memory and concentration;
  • magnesium – supports the functioning of the nervous system andcirculatory;
  • calcium – influences the proper structure of bones and teeth, additionally strengthening them;
  • chlorine – regulates water-electrolyte balance and supports the appropriate pH of the body;
  • sulfur – supports liver function and increases joint flexibility.

Remember what you drink. Healthy water is essential! Choose mineral waters that suit your needs to support your health and well-being.
