Magnesium is the second most common mineral found in the body (about 25 g). It is evenly distributed between the skeleton (50-60% of total) and the soft tissues (40-50% of total). In the skeleton, about one third of the magnesium is on the surface of bone. Body magnesium is most closely associated with cells; only 1% of total body magnesium is extracellular. Within the cell, magnesium is found in all of the compartments.
Epsom salt is also known as magnesium sulphate. It is a chemical compound made up of magnesium, sulphur and oxygen. When Epsom salt is dissolved in the water, it releases magnesium and sulphate ions. These ionic mineral particles can be absorbed through the skin, providing the body with magnesium and sulphates. These are minerals that have important functions in the body. The most common use for Epsom salt is in baths, where it is simply dissolved in bath water, and whole body is immersed in the solution. However, instead of whole-body immersion a specific part of the body can be soaked in Epsom salt solution; for example, foot bath or hand soak, it can also be applied to the skin as a cosmetic product. We do not recommend to ingest Epsom salt.
