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.

Food that contains this element the most.

Chloride

Chloride (Cl) tastes salty and a bit bitter.

Chloride, along with other minerals, affects the osmotic pressure in the cells and the balance of the body's acid-alkaline balance.

Combined with hydrogen, it forms the hydrochloric acid in the stomach and thus promotes digestion.

If the body lacks chloride, symptoms include stomach acid disorder, diarrhea. Chloride as an ingredient in gastric juice ensures the balance of acids and alkalis.

Chloride deficiency can be manifested in muscle spasms or heart dysfunction.

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.

Sodium

Sodium (Na) has a salty taste.

Combined with chloride and potassium sodium regulates fluid balance in the body, it is necessary for nerve and muscle activity, for the activation of enzymes.

Most often sodium is taken with salt-containing products.

Every day you need 3000 mg of sodium and 3000 mg of chloride. Athletes need more sodium.

Sodium deficiency can cause weakness and seizures, even up to the circulatory collapse, especially in sports.

Caution: Sodium is not the same as cooking salt.

If there is a lot of physical activity, the amount of sodium needed per day may increase.

We often hear alerts on sodium overdoses, usually associated with salt in the diet. The cooking salt is a chemical compound - sodium chloride.

Mineral waters typically contain sodium in the form of sodium bicarbonate and only very small amounts such as sodium chloride.

If you are considering a low salt diet, use mineral water with low sodium content.

Nitrat

Nitrate (NO3). The presence of nitrates indicates water pollution.

Nitrates in water may also be of natural origin, without chemical pollution of water. Geologists have observed that naturally, nitrate levels can be up to 15mg / l.

A small amount of nitrates is found even in waters where they should not seem to be. For example, in glacial waters, where hundreds of kilometers of economic activity do not occur.

We ingest nitrates with food or drinking water. They are harmless to adults without intestinal problems if the limit values are not exceeded.

Compared to tap water, mineral waters are mostly low in nitrate. Mineral waters are more protected from environmental effects, such as fertilizers and other chemicals, as sources are usually deep underground and are regularly tested.

The nitrate limits are:

• 0-1 mg / l - superior,
• 1-4 mg / l - very good,
• 4-7 mg / l - well,
• 7-10 mg / l - acceptable,
• 10-50 mg / l - within the normal range.

But if NO3 and NO2 pollution is not indicated on the bottle, it does not mean that it is not there.
