Magnesium is an essential mineral that every human being needs above all for the optimal nutrient supply of the muscle cells. A deficiency of magnesium manifests itself in frequent muscle cramps, muscle twitching or migraines. A sufficient supply of magnesium (300-400mg/day) can prevent these deficiency symptoms. Zechstein Magnesium Oil is not an oil in the true sense of the word, but a magnesium chloride solution with an oily consistency. The magnesium oil is sprayed directly onto the skin, where it is absorbed and transported to the cells. It is therefore particularly suitable for athletes, as magnesium in this form can be easily absorbed through the muscles. The magnesium comes from the Zechstein Sea in the Netherlands.
