Calcium

Calcium (Ca) can leave a dry aftertaste.

Calcium strengthens bones, teeth and is responsible for nerve impulse action.

If you eat dairy products on a daily basis, that's enough. The other good alternative may be calcium-containing water.

Calcium plays an important role in the formation and maintenance of bones and teeth.

Calcium in the nerves and muscle cells is responsible for impulse and hormonal signal transmission. It also regulates the activity of different enzymes, it has anti-inflammatory and anti-allergic properties.

Every day you need about 1000 mg.

Young people and seniors should receive more calcium. Especially a lot of calcium is in milk and cheese. If you do not eat dairy products every day, calcium-containing mineral water is a great alternative.

If calcium is lacking, the body is taking it from the skeletal bone, which can cause osteoporosis or "bone loss" in the long run. Especially it may affect older people, mainly women. Calcium deficiency can also cause headaches, muscle spasms, and irritability.

Fluoride

Fluoride (F) has a sweet and soapy taste and it plays a very important role in bone and tooth structure.

Fluoride naturally occurring in water can be above, at, or below recommended levels.

Fluoride remains in the teeth and can inhibit dental caries. It also increases bone density.

The result of fluoride deficiency may be brittle bones and bad teeth.

Caution: too much unhealthy. Children and adolescents need fluoride for growing teeth, but they should not be consumed too much. Therefore, the legislator has laid down an appropriate reference to the labeling of mineral waters with a fluoride content of more than 1.5 mg/l. For children under 7 years of age, it is not recommended to drink such water every day for prolonged periods.

Fluoride tends to be concentrated also in tea, coffee, shellfish, spinach, grapes, raisins, carrots, wine, cucumber, dill herb, tomatoes, asparagus, beans, peas, white rice, and potatoes.

It is important to understand that natural fluoride and synthetic industrial fluoride is quite a different substance.

Potassium

Potassium (K) provides water balance in the body.

It tastes a bit salty and bitter.

Potassium plays an important role in the regulation of fluid and acid-alkaline balance.

Potassium activates various enzymes and is especially important for heart and muscle activity.

Potassium is up to 98% in the body cells.

Potassium deficiency causes muscle weakness, decreased blood pressure, disturbances in heart rate, loss of appetite, and constipation.

A good recommendation for active athletes is to consume potassium-rich waters.

Potassium regulates cardiac and muscle activity relaxes muscles and nerves. Together with sodium, it helps to maintain the balance of water in the body.

When eating plenty of vegetables, fruits, and milk, you can take the necessary 2 grams of potassium daily.

Magnesium

Magnesium has a bitter taste, sometimes it can give a sweet aftertaste.

Magnesium is a very important element for the heart.

It is considered to be an antistress mineral and is also vital for the skin.

Magnesium is important for the transport of nerve impulses, which helps the muscles to relax.

Magnesium activates more than 300 enzymes in the body and regulates electrochemical impulses.

Every day you need 350 mg for men, 300 mg for women, 400 mg for young people.

More magnesium is needed for pregnant women, athletes, and people in stressful situations.

Manifestations of magnesium deficiency: leg cramps, migraine, headache, cardiac and circulatory organ failure, may be at increased risk of thrombosis.

Nitrit

Nitrite (NO2). Nitrites enter the human body in two ways: by direct content or by nitrates, which in the digestive tract (mainly in the oral cavity, also the stomach or intestine), are converted into nitrites by the action of the enzyme nitrate reductase.

The presence of nitrites indicates the contamination of water.

In the European Union, the permissible daily dose of nitrites is 0.1 mg/kg of mass (in terms of sodium nitrite)
