Coffee is one of the two most widely consum ed beverages in the world, and comes in many different varieties and preparations. It is safe to say that even the English, so far attached to their traditional afternoon tea, increasingly prefer to replace it with a cup of aromatic, strong coffee. Its main ingredient is caffeine, found not only in coffee, which has numerous healing properties and has a beneficial effect on health, of course when supplied in moderation, in recommended doses.

From a purely scientific point of view, caffeine is simply an organic chemical compound classified as a purine alkaloid. One of its characteristic features, distinguishing it from other compounds, is a unique, specific way of connecting carbon and nitrogen atoms in the molecule. It is a substance quite commonly found in nature, but it can also be obtained artificially, and the first synthesis of it was performed in 1819 by a German chemist Friedrich Runge.

Caffeine obtained in this way has the form of a white powder with a bitter taste, easily soluble in water.

The symptoms of addiction are similar to those of coffee intoxication, so that it is sometimes difficult to recognise them correctly and connect them with supplying the body with too much caffeine.

If we don’t want to give up coffee, additional supplementation of this element will be necessary to supplement the resulting deficiencies. If one cup of coffee is not enough for us, drinking more we must remember that it causes increased urination, and with it we remove calcium, potassium and magnesium, which causes a significant loss of bone mass.
