What are Epsom Salts?

Epsom Salts are a naturally occurring mineral compound (Magnesium Sulphate in crystal form). Epsom salts have been used for hundreds of years as both a beauty therapy, and for the treatment of health conditions.  However, today, most Epsom Salt are manufactured in a laboratory.

How to use Sam Walker Epsom Salts

Because Epsom Salts are a natural detoxer, you’ll need to start slowly (as you would with any detox) to ensure you don’t push your body too quickly.

Start with half a cup or less of Epsom Salts in a bath (or foot bath) of water per day. Soak in the bath for at least ten minutes every day.

You can soak for up to 30 minutes a day – relax and enjoy!

Over a period of a few weeks, you can increase the quantities to two to four cups of Epsom Salts in a bath of water per day.

For babies, young children, and those with eczema, start super low and super slow, just a teaspoon at a time, and gradually increase.  If you have kidney disease please consult your doctor before using.

Epsom salts are absorbed through the skin when used as a bath soak, effectively increasing the level of magnesium and sulphates in the body. A good soaking does wonders!


Magnesium is a key ingredient in Epsom Salt, it’s a mineral that’s essential for good health.

Magnesium is needed for more than 300 biochemical reactions in the body. It helps to maintain normal nerve and muscle function, supports a healthy immune system, keeps the heart beat steady, and helps bones remain strong. It also helps regulate blood glucose levels and aid in the production of energy and protein. There is ongoing research into the role of magnesium in preventing and managing disorders such as high blood pressure, heart disease, and diabetes.

Sulphates (sulfates) are also essential for good health.

  1. Sulfate is essential for many biological processes.
  2. Sulfate is needed for formation of proteins in joints; low levels of sulfate are found in plasma and synovial fluid from patients with rheumatoid arthritis.
  3. Sulfate is needed to start the cascade of digestive enzymes released from the pancreas. Without proteases, lipases and amylases, food is not digested efficiently.
  4. Sulfate is essential in forming the mucin proteins which line the gut walls. These have 2 main functions – they stop the gut contents from ‘sticking’ and they block transport of toxins from the gut to the bloodstream. Low plasma sulfate has been found in patients with irritable bowel disease.
  5. Sulfate is necessary for formation of brain tissue. Before birth, the functional units of the brain, ‘neurons’, are laid down on a scaffolding network of sulfated carbohydrate chains. Reduced sulfation can lead to faulty neuronal connections and later dysfunction.
  6. Sulfation is a major pathway in detoxifying drugs and environmental contaminants.
  7. Sulfate is not easily absorbed across the gut wall. Recent research has shown that it can be absorbed across the skin. It is also formed in the body by oxidation of the aminoacids cysteine and methionine. However, this pathway is often sub-optimal and many people benefit from sulfate supplementation.

How long will my Epsom Salts last?

I am often asked this question.  It will depend on how many people are using the salts, how much you use and how often you bath.

As a guideline most people start with half a cup and gradually increase to 2 cups, some people use 4 cups.  Many people bath every night in Epsom Salt.

1 cup of Epsom Salt weighs approximately 240g, so…

1kg = 4 cups

5kg = 20 cups

10kg = 40 cups

15kg = 60 cups

20kg = 80 cups
