Minerals are essential for the body. Insufficient quantities can lead to certain deficiencies. Too much of them can cause premature kidney fatigue.

But what are they used for, are they present in tap water and what happens when you use Berkey® filters? The explanations are given below.

Minerals are present in water in the form of mineral salts from the rocks through which it passes. Did you know that they are present in relatively high quantities in the human body, up to a few grams for some of them? They are mainly calcium, magnesium, phosphorus and potassium, but also sodium and iron.

These minerals, which are essential for health, play an important role in the regulation of water in the body, for cardiac activity, the maintenance of hair or skin, as a regulator of blood circulation, but also for the constitution of tissues, or for the development of certain hormones and enzymes.

The body, through the kidneys, eliminates a certain amount every day. It is therefore essential to find supplements to compensate for this loss. These minerals are found in plant foods, in certain dairy products, meat or fish and seafood, but also in significant quantities in drinking water.

And contrary to what we might think, tap water also contains minerals! Indeed, in its natural course, like mineral water, it is loaded with mineral salts and trace elements. Among other things, it contains calcium, up to 25% of daily needs (depending on the region) and magnesium, from 15 to 20 mg per liter.

Unlike mineral water, which often contains a significant amount of magnesium, tap water does not contain as much. If we consider that we eat a balanced diet, the mineral intake is largely compensated by the absorption of plants and other foods rich in minerals such as whole grains or nuts. Too much consumption of mineral water leads to an overconsumption of minerals, forcing the kidneys to work hard to eliminate them. The mineral intake of tap water is therefore finally interesting and sufficient.

These elements are essential to our health, so why remove them? Well, the Berkey® filters used in our purification systems do not remove them. They retain the undesirable pollutants but allow the mineral salts to pass through.
