Epsom salts are Magnesium sulphate. Magnesium is a key micronutrient that most of us are deficient in. Not only does it assist in many health benefits, from reducing inflammation and relaxing the body, but also helps muscles and nerves function properly. Proper magnesium and sulfate levels increase the effectiveness of insulin in the body, and can help to lower the risk or severity of diabetes, as well as draw toxins out of the body. Therefore bathing in it is great to support weight loss.
 
Use 2 cups from the 1.5kg bag and it will last you three or so baths. Otherwise, using a smaller amount per bath will allow for more long term use.
