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.

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.

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.

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)

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.
