For their amount fold up 46 ingredients, and 30 of them are thought as essential to live. Mineral ingredients are taken almost solely with nourishment, because human's organism has no ability to produce them.

Classification of minerals, functions, food sources, nutritional requirements, interesting facts 
  Mineral ingredients in respect of organism demand are divided into two groups: macro elements and micro elements (trace elements). Macro elements are elements for which daily requirement exceeds 100 [mg]. Daily requirement for micro elements does not transcend 100 [mg].

Function of minerals: 
Calcium constitutes a part of build material of bones and enamel. Calcium is constantly exchanged - this exchange is based on building it into bones and enamel and resorption. It fulfills a role in conducting nervous impulses, mechanism of muscle contraction, permeability of cellular membranes, in adjustment of blood coagulation process, adjustment of heart beat and absorption of vitamin B12, affect arterial pressure control. Correct concentration of calcium reduces hazard of occurring heart diseases, stroke, large intestine cancer, and kidney calculus. It is in composition of many enzymes.

Food sources: 
Cheese, cottage cheese, milk, sardine, cress, eggs, cabbage, meat, potato, beet, pod vegetables, nuts.
