Supplements are drinks, powder preparations, chewable tablets at different concentrations and chemical-physical compositions that help to restore the correct levels of mineral salts lost through perspiration during normal physical activity or after a physical effort made in unfavorable external conditions.
Usually the basic formulation is composed of sodium, chlorine, potassium and magnesium.
A major cause of summer illness is excessive sweating. Sweating, the human body, expels a greater amount of water and mineral salts indispensable for the functioning of organs.

Potassium, along with sodium, is crucial to maintain the balance of the acid base, therefore, proper intake it is important. A shortage of potassium, can have an important impact on the heart muscle, leading to episodes of hypertension precisely for the accumulation of sodium in the cells.
Potassium stimulates the kidneys in urine production and thus combats water retention, swollen legs and accumulation of harmful metabolic waste in the limbs. Potassium deficiency leads to the immediate weakness, tremors, tachycardia, muscle cramps, swelling of the limbs and loss of muscle tone.
Magnesium and potassium are minerals which undergo a major decline in the human body during sweating.
