INCI: Magnesium Sulfate. The health benefits of Epsom Salt, seem to be becoming more well-known, making it a popular choice of many for bath time. Magnesium Sulfate, or Epsom Salt, was first discovered near the town of Epsom, England, hence the given name. Magnesium helps keep enzyme activity regular in your body, while also assisting your body functions to run smoothly. Sulfate plays an important role in the formation of brain tissue and joint proteins, and can strengthen the walls of the digestive tract. According to the Epsom Salt Council, more than half of Americans have a Magnesium deficiency. Taking a bath in Epsom salts can help restore both levels of Magnesium and Sulfate, as they can be readily absorbed through the skin. Product Origin: Arizona, USA.
