Similar to mineral water, spring water also comes from underground sources, but they are shallower and less strictly monitored.
Spring water can undergo treatment, such as iron or sulfur removal, filtration, or infusion with ozone-enhanced air. But it can’t be treated with chemicals. Only carbon dioxide can be added.
Mineral water comes from dozens or even hundreds of meters underground where pollutants created by human and agricultural activity can’t reach it. Moreover, no chemical treatment is allowed, so mineral water only contains what it was endowed with by Mother Nature.
Groundwater sources are strictly protected, and their quality is regularly and thoroughly checked. Mineral water must be bottled at its source. Its composition should be displayed on the label, so that you always know exactly what you’re drinking.
Even though tap water is usually drawn from protected surface water reservoirs or upper course rivers, it comes into contact with waste, chemicals and other impurities related to human activity.
To become drinkable, it must undergo thorough mechanical and, more importantly, chemical purification, most often using chlorine which may be hazardous to some of us. Moreover, even after purification, some bacteria may still remain.

Why do we need minerals?
Magnesium (Mg) 24.3 mg/l
is important for the normal functioning of our nerves and muscles. It relaxes tissues and organs and helps relieve muscle tension in case of back or neck pain. It boosts immunity and helps prevent kidney stones and heart diseases. Magnesium and calcium intake must be kept in balance. Therefore, Korunní mineral water contains their optimal ratio of 1 (Mg) : 2 (Ca).
Calcium (Ca) 68.4 mg/l
is vital for the healthy development of our bones and teeth. It also promotes regular transmissions between nerve cells and plays an important role in the formation of digestive enzymes and metabolic hormones. Optimal calcium intake enhances the absorption of magnesium and vice versa. Therefore, Korunní mineral water contains their optimal ratio of 2 (Ca) : 1 (Mg).
Sodium (Na) 74.7 mg/l
is essential for the production of red blood cells and hydrochloric acid that aids digestion in our stomach. It stimulates kidney activity, and its lack can cause dehydration. But excess sodium isn’t healthy either. Therefore, Korunní has a balanced sodium content, so you can drink it every day.
Potassium (K) 17.5 mg/l
maintains the right fluid balance in our body together with sodium. It has a beneficial impact on blood pressure, heartbeat, and nerve activity. Since it’s also crucial for muscle activity, it’s especially important to athletes.
Total dissolved solids (TDS) content in Korunní: 493 mg/l
Based on its mineral content, mineral water can be classified as lightly, moderately, or highly mineralized.
Since it falls under the lightly mineralized category, Korunní is a suitable choice for daily water consumption.
Fluorine (F) 0.61 mg/l
is an important component of bone formation and also contributes, among other things, to tooth decay prevention. It also promotes the production of the necessary organic compounds in our kidneys.
